Cloud FAQ

What is cloud computing

Cloud computing is a marketing term for technologies that provide computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. A parallel to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.

Network HA Design virtual servers

Cloud computing describes a new supplement, consumption, and delivery model for IT services based on Internet protocols, and it typically involves provisioning of dynamically scalable and often virtualised resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet. This may take the form of web-based tools or applications that users can access and use through a web browser as if the programs were installed locally on their own computers.

Cloud computing providers deliver applications and services via the internet, which are accessed from web browsers and desktop and mobile apps, while the business software and data are stored on servers at a remote location. In some cases, legacy applications are delivered via a screen-sharing technology, while the computing resources are consolidated at a remote data center location.

At the foundation of cloud computing is the broader concept of infrastructure convergence (or Converged Infrastructure) and shared services. This type of data centre environment allows enterprises to get their applications up and running faster, with easier manageability and less maintenance, and enables IT to more rapidly adjust IT resources (such as servers, storage, and networking) to meet fluctuating and unpredictable business demand.

Most cloud computing infrastructures consist of services delivered through shared data-centres and appearing as a single point of access for consumers' computing needs. Commercial offerings may be required to meet service-level agreements (SLAs), but specific terms are less often negotiated by smaller companies.

The tremendous impact of cloud computing on business has prompted the federal United States government to look to the cloud as a means to reorganize their IT infrastructure and decrease their spending budgets. With the advent of the top government official mandating cloud adoption, many agencies already have at least one or more cloud systems online.

Some very good examples of Cloud Computing are Salesforce, Google Docs, Skydrive, Dropbox, Hotmail, Zoho Office, Xero plus many more.

What is virtualisation

Virtualisation is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources.

Virtualisation allows multiple operating system instances to run concurrently on a single computer and by inserting (or installing) a virtualisation layer (or a Hypervisor) on the computer hardware you can effectively separate the hardware from each individual single operating system as per the below diagram.

A Virtual Data Centre (using virtualisation) is a data centre which is created 'Virtually', effectively in memory, on an existing shared computing platform which would be housed, or located within a 'Physical Data Centre'.

The Virtual data centre provider will have several very high performance and high capacity 'physical servers' and in a 'virtual' fashion, segregate and divide the total resources of the physical platform to serve many Virtual Data Centres or Virtual Servers.

Diagram explaining what is virtualisation

This diagram is a simplified representation of what the layers of the Virtual Data Centre are.

Physical Layer - is the physical server, networking equipment and routers and hard disk storage devices

Hypervisor Layer - is effectively the operating system which controls the physical hardware and is the 'container' which allows multiple 'virtual machines' or 'virtual servers' to operate on top of a single physical server. The Hypervisor controls the sharing of all physical resources such as memory and processing and ensures all of the 'guest hosts' (hosted virtual machines) co-exist and 'play nicely together' on the same physical hardware.

Virtual Machine Layer - is what we currently know as the operating system and applications that make up either a server or computer. A good example of a server virtual Machine (VM) would be a Windows Server running Exchange which combined acts as an email and collaboration server, or, the VM could run Windows 7 with Microsoft Office and this could be a user's desktop machine.

End Users - the end users of the VM could be you or me when we check our email, or type a letter or watch a YouTube video or do whatever else it is that we do as IT consumers. The end user function could also be that of a simple off site backup for all of our important data.

As a simple example, let's say you buy a physical server from IBM and ensure it is configured with as much memory and processing power as you can get in it. Let's say you have 100 Gigabytes of memory. Onto that server you could very easily load 10 x Exchange email servers as described above while simultaneously running over 60 x Windows 7 desktop machines for end users.

What are the benefits of cloud computing

  1. Reduced costs: Cloud computing reduces your hardware (computers, software (all those downloaded programs), networking management and overall IT expenses. In addition, with cloud computing, you only pay for what you use, when you use it.
  2. Scalability: You can scale your business' storage and processing needs seamlessly rather than having to go out and purchase expensive programs or hardware. A not-for-profit ran a cookbook project and was able to pay for all the cloud apps they needed to create, implement and market their project on a month to month basis. They didn't have to purchase any hardware, buy software licenses or worry about overloading their servers.
  3. Automatic Updates: There is no need for IT to worry about paying for your future updates in terms of software and hardware as it is all catered for in monthly licenses.
  4. Remote Access: employees, partners and clients can access, and update information wherever they are, rather than having to run back the office.
  5. Disaster Relief: With your company's data safely stored in secure data centres instead of your server room (previously known as your storage closet), losing power due to storms, earthquakes or a construction worker cutting the power lines, you are back at work as long as you have an internet connection.
  6. Ease of Implementation: Your IT team (hopefully older than a 10 year old) may not like this, but implementing cloud services can be as easy as, well, setting up a Facebook page.
  7. Skilled Vendors: Who would you rather manage and protect your data? A company such as DC Two (where staff combined have over 40 years experience serving enterprise clients), IBM or Amazon or your IT staff?
  8. Response Time: Cloud computing accomplishes a better response time in most cases than your standard server and hardware.
  9. Even playing field for small firms: This allows small companies to compete more effectively with some of the larger businesses, balancing the playing field. Your small business can utilize the same tools that Fortune 100 companies use and can do this because with cloud computing, your business will only pay for what you need (see #1).

What are the costs of cloud computing

Cloud Computing, when compared to an on-premise deployment, in most cases, can end up being less expensive and more valuable.

Cloud Computing however does not come free, there are costs, but it would be expected that any savings made by moving workloads to the cloud would outway any additional incremental costs incurred by moving to the cloud.

What are the items that you will need to consider for a like-to-like comparison?

Capital Expense (CAPEX) Items such as;

  • On-premise Hardware including Servers, storage, switching, routing, UPSs, racks, PDUs and any annual maintenance for hardware support or firmware updates etc.
  • On-Premise software including Microsoft Windows, Office and other licenses, backup software and any annual maintenance for those software items.
  • Cost of Money - CAPEX spent on the on-premise hardware and software itself has value, don't forget to include the opportunity cost of putting that cash into hardware versus investing it elsewhere in the business. (ie. a crane hire business could buy another crane to generate more revenue)
  • Facilities - How much space (and therefore rent) does your server hardware and equipment take up? 1 rack, several racks, perhaps an entire server room, or maybe you have your equipment in a colocation data centre already? These costs all need to be added.

Operational Expense (OPEX) Items such as;

  • Telecommunications links for internet OR dedicated point to point links - dedicated point to point links direct to the cloud data centre can deliver a lot higher bandwidth at a much lower cost versus an internet connection with internet being delivered through the cloud data centre.
  • IT Support - There is no longer the requirement to service on-premise hardware
  • Insurance - Less equipment on-premise equals lower insurance premiums
  • Power - The average physical server will consume about $80 worth of power each month
  • Off-Site backup - Once you have migrated to the cloud, there is no need for off-site backup, your cloud provider should be performing regular proper backs as part of the service.
  • Traditional telephony versus Cloud IP Telephony - A properly configured and deployed business Voice Over IP (VOIP) PBX service can provide many benefits and much costs saving versus a traditional PABX/PBX system.
  • Any business specific costs - Each business has specific operational cost items - what are yours?
  • Every business is different and this is why you should undertake a complete cost comparison analysis, we can help you with this if you need some assistance.

We undertook a very comprehensive ICT Architecture Scoping Study for a health service that will be operating across 12 sites with over 230 staff across some of the most remote areas of Australia. The study required us to compare three complete deployment options including full cost comparisons for each over a 36 month period.

Some of the results along the way actually surprised us but the outcome was not surprising with the Private Cloud solution working out about 8% less over 3 years than the next closest option.

Cloud computing deployment models

Public cloud

A public cloud is one based on the standard cloud computing model, in which a service provider makes resources, such as applications and storage, available to the general public over the Internet. Public cloud services may be free or offered on a pay-per-usage model.

Community cloud

Community cloud shares infrastructure between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally. The costs are spread over fewer users than a public cloud (but more than a private cloud), so only some of the benefits of cloud computing are realised.

Hybrid cloud

Hybrid cloud is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models. It can also be defined as multiple cloud systems that are connected in a way that allows programs and data to be moved easily from one deployment system to another.

Private cloud

Private cloud is infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally.

Private clouds have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from lower up-front capital costs and less hands-on management, essentially "lacking the economic model that makes cloud computing such an intriguing concept".

The irony of cloud computing is that contrary to it's name, every cloud must exist on the ground, in a data centre somewhere!

What do Cloud Computing and Virtual Data Centres have in common?

Just as Cloud Computing is the much publicised marketing phrase for the next genration of hosted applications, the key distinction between Cloud computing and traditional computing is that a cloud environment is virtual and elastic.

For consumers, a properly designed and executed 'Virtual Data Centre' offers the virtualisation capability for Cloud just as the same should be able to offer the flexibility and adaptability to ensure that the Virtual Data Centre also has the elastic properties to allow consumers to scale up resources as demand warrants, just as easily as scaling down resources when demand wains.

A great example of this elasticity would be an accounting firm requiring more processing power at the end of the financial year to perhaps process end of financial year accounts for clients or the christmas period for retailers requiring handling many more transactions.

How do you buy virtual data centres

When a business wishes to utilise the services of a Virtual Data Centre (or VPS) provider, they should be presented with a 'menu' of choice with the below as the key options;

See our MyDaaS product website for full information.

  1. Location: Where will the VDC or VPS be physically located? Which city, country or other specific location will host the platform. There are several laws which are country specific which require certain data to remain within borders. As an example, New Zealand's tax laws require that tax accounting information must remain within New Zealand. This has posed a problem for Cloud accounting software company Xero, which is NZ based and host their platform with a data centre in the USA.
  2. Processor or CPU: Each VPS requires a certain amount of processing power. Smaller less critical VMs such as a simple web servers need very little whereas a database server which processes mining assay data will require significantly more power. CPU is usually sold either by the vCPU core or Ghz (speed of the processor). Processor requirement and memory are almost linked, the more memory a VM needs, the more processing power is needed to process the data stored in the memory.
  3. Memory or RAM: Memory is the most significant piece when sizing a VM as all operating systems and applications need to operate within system memory. Too little and the system will run poorly and too much and resources will be wasted.
  4. Storage or HDD: The amount of storage, or hard disk space, will depend on the actual amount of data that needs to be stored. Storage comes in almost as many shapes and sizes as there are colours in the rainbow, however, it can generally be categorised into 4 or 5 levels of performance and sold accordingly. Some applications and systems, such as database and email systems require high performance storage (Tier 1 and 2 with SAS and maybe SSD disks), whereas general office servers sharing files can comfortably reside on lower performance storage (Tier 3 with NL SAS and SATA disk) while a business' off-site backup storage could very happily be housed on high capacity, low performance SATA disk. Selecting correctly between capacity and performance can have a drastic positive, or negative, impact on the overall price of the storage and performance of the VM.
  5. Data Traffic: There are 2 main ways to access a VDC, either through the internet or via a dedicated point to point connection which could be put in place to connect the VDC back to the business' principal place of doing business.
  6. IP Addresses: To access the VDC, or VMs inside the VDC across the internet, the business will need to be allocated a certain number of IP addresses. The more distinct applications running inside the VDC there are that require direct access from the internet, the more IP addresses will be required.
  7. Network and Security configuration: There are several ways to separate and segregate VDCs from a network security perspective, either they can be deployed in a small 'shared pool' or in a dedicated 'Virtual Local Area Network (VLAN)' or perhaps even on dedicated physical hardware to provide a higher level of security and separation from the other users on the platform.
  8. Operating System: The choice of Operating Systems is almost limitless and this will greatly depend on the applications that are required and the preference of the business. Some popular operating systems are;
    • Microsoft Windows Server
    • Microsoft Windows 10
    • Ubuntu Linux
    • CentOS Linux
    • Debian Linux
    • Open Indiana (Open Solaris)
    • FreeBSD
    • And many more
  9. Applications: Applications which run inside the Operating system are even more numerous than the operating systems. Some popular applications are;
    • Microsoft Office (Word, Excel, Power Point, Outlook etc)
    • Web Browsers such as Internet Explorer, Mozilla, Firefox
    • itunes and other music and video applications
    • Microsoft Exchange email server
    • Microsoft SQL database server
    • MYOB, Quickbooks or other accounting applications
    • Plus many, many more

General FAQ

What are cloud desktops

  • VDI simplifies desktop administrative and management tasks
  • Users access virtual desktops running in the Data Centre
  • Technology Supports both PCs and thin clients
  • Desktop security and data protection are centralised
  • Access can be easily extended to remote users

Many companies have turned to virtualization technologies for their servers in their data centres to simplify administration and to reduce management chores and operating costs while maintaining reliability and safeguarding against disasters. Seeing the significant benefits virtualization delivers in those environments, companies are now looking to apply the same technology to their desktop computers.


The idea behind what is called a Virtual Desktop Infrastructure (VDI) is to run desktop operating systems and applications inside virtual machines that reside on servers in the data centre. Desktop operating systems inside virtual machines are also referred to as virtual desktops. Users access the virtual desktops and applications from a desktop PC client or thin client using a remote display protocol (RDP) such as Microsoft's RDP, VMware View's PCoIP, or even a Citrix technology and get almost the full features as if the applications were loaded on their local systems, with the difference being that the applications are centrally housed, hosted and managed.

Key Benefits of VDI

  • Efficient Use of CPU and memory resources
  • Reduced desktop downtime and increased availability
  • Patches and upgrades performed in data centre
  • New Users can be up and running quickly
  • Data and applications reside in secure data centres
  • Centralised management reduces operational expenses

Similar to server virtualization, VDI offers many benefits. Specifically, desktop administrative and management tasks are significantly reduced; applications can quickly be added, deleted, upgraded, and patched; security is centralised; and data is easier to safeguard and back up.

In today's work environment, where workers can be in geographically dispersed, remote offices, the data stored on distributed desktop computers is often vital to the operation of the business. Such data could include correspondence and documentation that would be essential in protecting intellectual property. Or the data could be essential corporate records, files, or data.

Regardless of what the data is, there is generally a need to protect it from corruption and it must be backed up in case of a hard disk crash, user error, or malicious destruction.

How can I deploy Virtual Desktops (VDI)?

To enable the proper design and deployment of Microsoft Windows Virtual Desktops (VDI) environments, we will need to consult with the business users to ensure that the correct hardware platforms and Microsoft licensing is deployed which will optimise costs and increase ROI.

What is a virtual server

A Virtual Server is a server that shares computer resources with other virtual servers. In this context, the virtual part simply means that it is not a dedicated server -- that is, the entire computer is not dedicated to running that individual server's software.

Traditional architecture vs Virtual Architecture

Virtual Servers are a very popular way of providing cost effective hosting services. Instead of requiring a separate physical computer for each server, dozens of virtual servers can co-reside on the same physical computer. In most cases, performance is not affected and each virtual server behaves as if it is being served by it's own dedicated physical server. However, if too many virtual servers reside on the same physical computer, or if one virtual server is allowed to hog resources, the other virtual servers on the same physical server could operate more slowly.

To ensure performance on the DC2 Platform, every Virtual Server or Virtual Data Centre is restricted to a maximum amount of resources to ensure that no individual Virtual Server or Virtual Data Centre can hog more resources than they are allowed.

The diagram shows you the logical difference between a traditional Physical Server deployment and Virtual Server architecture with the VMware layer installed between the physical computer and the Operating System (OS) and Application (Apps) layer. VMware controls, shares and allocates the physical resources amongst all of the Virtual Servers and ensures that they all work together properly.

What is a virtual data centre

VM Ware virtual data centre structure

As an extension from the Virtual Server, Virtual Data Centres are best described as a dedicated set of resources (or a Resource Pool) on the host Physical Servers.

The maximum (and reserved) resources of the Resource Pool are defined in VMware and the individual Virtual Machines are pooled together in groups to be managed together.

Virtual Data Centres are a great way for organisations requiring larger amounts of resources to deploy and manage those resources.

In the diagram, you can also see that Resource Pools can be 'nested' inside each other. Nesting Resource Pools can make it easy for larger organisations to allocate and divide the Parent Virtual Data Centre, or Parent Resource Pool, into further 'child' resource pools suitable for departments, or sections within the main business.

Networking FAQ

Virtual Server Basic Security

Diagram showing virtual server basic network security for VMs

VPS Basic security is the base security level on the DC2 Platform which secures single VPSs in several ways;

  • Username and Password security on the Virtual Machine Operating System. Having a secure username and password policy is always the first best line of defence for any computer system and often overlooked.
  • Shared Firewall. All virtual machines are protected behind a DC Two managed firewall to protect communications to and from the external internet and connections. There will be a maximum of 64 hosts behind any individual VM Secure firewall appliance.
  • Internet Port Blocking. The Shared Firewall will be set up to automatically block all ports to your virtual machines except for those specifically required by you to operate your platform.
  • Shared VLAN. Each Shared Firewall above is also protected within a private VLAN to provide segregation and separation of the network segment from the rest of the DC2 Platform.
  • MAC Address locking. Even though there are some shared elements to the networking and deployment of the individual VPSs, the firewall is also configured to lock the network port MAC address of your VPS to your IP adresses.

VPS Basic Secured VPSs can only connect to external communications via the internet as below;

Private Cloud Security with VLAN (Virtual Local Area Network)

A Private Cloud VLAN and private DMZ firewall appliance is the next level of security on the DC2 Platform which secures all of your chosen VPSs in a private, dedicated Virtual Local Area Network (VLAN) behind your own private firewall appliance or device;

Diagram showing private cloud security for VMs on VLAN
  1. Username and Password security on the Virtual Machine Operating System. Having a secure username and password policy is always the first best line of defence for any computer system and often overlooked.
  2. Private Firewall. All of your virtual machines are protected behind your very own firewall virtual appliance or physical device to protect communications to and from the external internet and/or other connections. There can be as many hosts behind your firewall as your network requires. The firewall can be deployed in a few different ways;
    1. By a DC Two supplied and managed virtual firewall appliance.
    2. By a Customer supplied virtual firewall appliance. You may have and use virtual firewalls elsewhere across your network and wish to continue to use what you are familiar with. DC Two can load your preferred appliance onto the DC2 Platform for you.
    3. By a Customer supplied physical firewall/router. Your network and other remote sites may already be configured with a physical security device such as a small Cisco ASA or Juniper SRX. DC Two can install your physical device in our data centres for you to enable consistency and stability in your operating platforms.
    4. If you would prefer, DC Two can supply your very own dedicated physical firewall/router. Please contact DC Two for further details and specifications.
  3. Internet Port Blocking. Any firewall set up will be able to block all internet ports to your virtual machines except for those specifically required by you to operate your platform.
  4. Private VLAN. Your Firewall will provide internet protection for your servers while a Private Dedicated VLAN will provide network segregation and separation for all of your VMs form the rest of the DC Two network and platforms.
  5. IPSEC and VPNs. Now you have your own private VLAN and DMZ firewall appliance, it is very easy to deploy and configure secure VPN tunnels enabling multiple locations to be connected (effectively) on the same private network.

A Private VLAN and Firewall will provide a great level of security for hosting companies and any deployments needing a good, secure internet hosting solution as shown in the diagram below;

Private Cloud Security with VLAN with Direct Connect

A Private Cloud VLAN with a firewall appliance connected back to your main office via a dedicated Point to Point (Direct Connect) communications connection (fibre, BDSL, ADSL etc) is a great way to connect your business premises to the Cloud.

The Private Cloud VLAN and P2P offers all of the same levels of security as the Private Cloud VLAN option with some extra benefits;

Dedicated Point to Point communications - A dedicated, secure point to point communications link between your site and the data centre can achieve several things;

Diagram showing private cloud security for VMs on VLAN with Direct Connect
  1. Reduce communications costs. If your have a larger number of users, implementing a dedicated point to point link to your office via fibre optic or other connection could reduce your overall communications costs when migrating to the cloud. Dedicated point to point links are much less costly to deploy than open internet connections.
  2. Increased Speed and Capacity. Dedicated links generally come in much higher speeds and with unlimited data capacities which is perfect for connections between networks.
  3. Decreased latency. When moving data across the internet you never know and can't control the path the data will take. Internet Service Providers generally route traffic along the shortest path, which obviously for them reduces their costs, but there are some ISPs whose local Perth traffic can travel via Sydney or Melbourne before heading back to Perth. A dedicated link WILL be configured by the provider to travel the shortest and quickest path. The lower the latency, the better the system will perform.

A Private VLAN with a private DMZ Firewall and a point to point connection is a great way for businesses to step into the cloud as shown in the diagram below;

Private Cloud Security with Direct Connect Only

Diagram showing private cloud security for VMs with Direct Connect only

A completely Private Cloud network is a good solid way for organisations who already have significant deployments based either at another site, or perhaps on-premise to increase IT compute or storage capacity without re-designing their networking infrastructure.

Connecting your existing networks to the DC Two hosting platform can enable your business to hook into the benefits of the cloud without any 'perceived detriments' while taking advantage of the cost and performance benefits of dedicated point to point communications connections.

Community Cloud Network Security

Diagram showing typical community cloud network security

Community Cloud Networks are a great way to share the benefits of the economies of scale that communities can enjoy.

Communities also often share a lot of data and information between each other and joining together and developing a Community Network, this data and information can much more easily be shared.

By mixing and matching the various internet, peering, P2P over a variety of connection types (fibre, BDSL, ADSL, satellite etc), VLANs, firewalls (physical and virtual), virtual servers and/or virtual desktops and many other components, DC Two can assist you to design, implement and operate whatever you require. Please do not hesitate to contact our team to help you put together whatever it is you are thinking of.

The below diagram is a good example of a Community Cloud that DC Two engineers designed for a regional Health Service in Australia.

Please do not hesitate to contact our team to help you put together whatever it is you are thinking of...

DC Two WAN Network and Carrier Availability

There are several ways you can connect to the DC Two Cloud platform including the below;

Internet connect

1 - Internet Connect

DC Two is an ISP (Internet Service Provider) operating our own BGP and DNS with both IPv4 and IPv6 address space for your internet connectivity, however, you also have the choice to bring your own if you so choose.

Unless specifically required, all of our VMs are supplied with private IP address space (RFC 1918) and then port mapped to external IP address space as required.

Direct connect

2 - Direct Connect

Depending on your communications and security requirements, you might find connecting a dedicated Point to Point communications service from your head and branch offices directly into the DC2 Platform to be advantageous.

Dedicated connections can be provided by a variety of carriers as listed below using a wide variety of mediums such as fibre optic, mid-band ethernet, ADSL, BDSL, SHDSL, ethernet, satellite and microwave.

Peer connect

3 - Peer Connect

Wherever we can, we connect our network with local 'peers' so we can share internet traffic with other network operators which can achieve several key things for our cutsomers inclduing lowering internet latency, increasing connection speeds and bandwidth all while lowering overall costs for those operators who 'peer' with each other.

If required, we can provide a 'Peer Connect' network ONLY connection which enables us to 'lock' your traffic to a specific network path which enables us to 'lock' in your traffic pricing at much lower prices which is very beneficial for off-site backup and cloud storage solutions in particular which both require lots of bandwidth to function efficiently.

Satellite connect

4 - Sat Connect

DC Two have a direct secure network connection into the Satcomms satellite network.

SatComms owns and operates it's own Earth Station (teleport) in Henderson, Western Australia. From this location, SatComms is able to Connect to global telecommunications partners, delivering customers' data & voice traffic with the level of security and performance required. The SatComms Teleport hosts customers' equipment and links remote sites to fibre and PSTN networks. This site also delivers Engineering & Support, along with the management of all customer networks end-to-end within the Network Operations Centre.

Combination connect

5 - Combination Connect

As you can see from the diagram below, it is also very simple for us to provide you with a Combination Connect to either some or all of the connection types of Internet, Direct, Peer or Sat, effectively allowing you to optimise all of your connections for both performance and price.

The DC Two network is flexible enough for you to have as many incoming network points as your network and deployment requires.

Network Hardware and Appliances Platform


DC Two have implemented the Juniper SRX Series Services Gateway devices which offer a high performance security, routing and network solution for enterprise and service providers. SRX gateways pack high port density, advanced security, and flexible connectivity, into a single, easily managed platform that supports fast, secure, and highly available data centre operations.

DC Two utilise both the hardware firewall functionality of the Juniper SRX Series Services Gateway devices and the virtual appliance software capabilities of our own custom built Hardened DMZ/Firewall appliance.


For switching DC Two have deployed Juniper's EX Series Ethernet Switches which address the access, aggregation, and core layer switching requirements of data centre environments, providing a foundation for the fast, secure and reliable delivery of applications that support strategic business processes. EX Series enterprise Ethernet switches deliver operational efficiency, business continuity, and agility.

In the data centre, the EX Series Ethernet switches are well suited to meeting the challenges of server virtualization and distributed applications. By implementing Juniper's 3-2-1 data centre architecture, the EX Series Ethernet switches enable enterprises to not only improve performance but also to increase operational efficiency.


The SRX Series Service Gateways and EX Series Ethernet Switches are based on Junos, Juniper's proven operating system which delivers security and advanced protection services, the foundation of the world's largest networks. Junos also supports rich routing and switching capabilities, and Junos' unique architecture provides reliable service operations and manageability, even under the highest loads.

Network Design

The below is a network diagram showing the High Availability design of each of the virtual platform nodes operated by DC Two.

Cloud Security on the DC Two Platform

The security of the DC2 Platform itself consist of many layers to ensure the ultimate protection for your Virtual deployments and includes the following features;


A Firewall is a device designed to permit or deny network transmissions based upon a set of rules and DC Two uses both hardware Juniper SRX firewall/security devices and hardened Linux virtual Firewall Appliances to secure our networks.

Active Intrusion Detection

DC Two has deployed an Active Intrusion Detection System (IDS) to monitor and secure our networks and systems for malicious activities.

Most network providers have only implemented standard IDS systems whereby they will be notified if there is a problem, but most of the time, by the time you realise there is a problem, it can be too late, whereby with an Active IDS system, the system itself will watch for malicious activities and pro-actively block and engage with the potentially malicious traffic itself.


A Virtual Local Area Network (or VLAN) has the same attributes as a physical Local Area Network (or LAN), but it is configured and run 'in memory' within the networking and communications equipment (switches and routers). A VLAN can also span across multiple switches and communications connections which can allow the VLAN to stretch out to connect remote sites.

VLANs are an ideal and very secure way to divide up network resources to allow multiple customers to share the same physical resources.

Network Segmentation

To ensure that the various network traffic segments do not interfere with each other, we have divided our internal network up into multiple VLANs. Network segmentation via VLANs keeps all of the network traffic such as SAN storage, internet, management, client data and any other traffic types completely separated from one another and unable to interfere and cause issue between each other.

Back End Hardware Management

All of the back end physical management interfaces and ports which control the base functions of physical servers, storage and networking hardware equipment are connected to their own completely separate physical network to ensure maximum security and segmentation and ensure that we always have full unencumbered access to control the entire platform, regardless of external communications.


All of the DC Two systems are monitored and checked every minute of every day by multiple alerting and notification systems to ensure that we can be on-top of any issues pro-actively, before they become a problem.

Cloud Security - Additional Options

Virtualisation is the creation of a virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources.

In addition to the standard security inclusions, there are also several additional security options which you may wish to deploy or implement depending on your requirements and needs such as;

BYO Virtual Appliance

DC Two provide a managed virtual firewall solution however you may wish to deploy a virtual firewall appliance that you are already using and/or familiar with. The DC Two virtual platform can facilitate just about any OS or virtual appliance but just to be sure, please contact DC Two with your specific enquiry.

BYO Physical Appliance

Perhaps your preference is to deploy a physical firewall appliance/device rather than virtual. DC Two can host your routers and join them into the DC Two virtual fabric very easily to give you full access and control over your environment.

Trend Micro SecureCloud

Trend Micro SecureCloud™ provides data protection for public and private clouds and your VMware vSphere virtual environments. Protect and control your confidential information with this efficient and easy-to-use data encryption service that keeps your data private and helps meet your regulatory compliance requirements.

SecureCloud can be deployed on hosted services or as an on-premise software application. Either way, you the customer, control the encryption keys, not the hosting provider, giving you the freedom to encrypt data in virtual data centers or in the cloud, and even to move data between cloud vendors.

Dedicated VM Nodes - Managed Compute and Managed Storage

If security is a serious concern for you and the above options still aren't enough, then considering private dedicated server hosts could be your next step.

DC Two would deploy sufficient physical server hosts dedicated just for you and your compute loads with your own managed private VMware environment, managed private Veeam backup environment which will ensure that the only network traffic that enters your hosts is your own traffic.

To take the dedicated hardware to the next level, we can, if required also deploy your own private managed SAN.
