VIRTUAL DISKS – SYSTEM AND DATA

Adjust your cloud solution by adding or removing data disks from your virtual servers at any time – from a minimum of 10GB to a maximum of 1,000GB in size.

Through the management console, you can create up to 15 virtual disks per virtual server.

You can also remove or increase the size of a data disk, but can't reduce it.

The system disk, which contains the operating system, can't be removed nor resized.

The system disk size depends on the operating system you choose:

Operating system System disk size
Linux® 10GB
Microsoft® Windows® Server 2003 20GB
Microsoft Windows Server 2008 40GB
Microsoft Windows Server 2012 60GB

IP ADDRESSES

Telstra will allocate a public IP address to each virtual server facing the internet in your network configuration.

You'll assign your own private IP addresses for the virtual servers connected to your private network. Both public and private IP addresses are static.

Configure up to two virtual network interface cards (vNICs) per virtual server.

ABOUT NETWORK AND SECURITY ADD-ONS

CONNECTING TO YOUR VIRTUAL SERVERS

Virtual servers can be connected to the internet and/or a private cloud network. You can connect one or more IP subnets to your private cloud network.

There are two options for connecting to virtual servers through a permanent, private network - the Telstra Next IP® network or an IPsec VPN network tunnel. Both can be requested through the management console.

A Telstra Next IP® network connection can reach all your IP subnets in your private cloud network.

IPsec VPN network tunnels connect only to the IP subnets you specify.

Return to top

 

REMOTE ACCESS TO VIRTUAL SERVERS

You can remotely access and manage virtual servers through SSL VPN technology – a secure client-to-site network tunnel used to remotely access your cloud solution from the internet. You access it over HTTPS, using a web browser. Once authenticated, you have direct access to virtual servers. All the network traffic will be transmitted securely.

Once you've established a VPN connection, you'll be able to use tools such as Remote Desktop Services or Secure Shell to manage your virtual server – just as if you were sitting in front of it.

Return to top

 

IPSEC VPN

To be reachable by IPsec VPN, a virtual server needs to be connected to a private cloud network.

Connect up to three IPsec VPN network tunnels at one time. Add and remove tunnels any time.

Specify one or more source subnets at a single office site and multiple destination subnets in your private cloud network – all within a single network tunnel. Use firewall rules to restrict access to selected virtual servers.

You choose the encryption and authentication protocols that secure your IPsec VPN connection, from the options below.

VLAN EXTENSION

Migrate virtual servers or create a hybrid cloud by extending VLANs between your on-premises infrastructure and our virtual data centre, sharing an IP subnet across both environments.

Connection is through a point-to-point VLAN Extension tunnel, over a Telstra Next IP® network.

VLAN Extension can extend subnets between Telstra cloud infrastructure and any site connected to your Telstra Next IP®network, including third-party data centres or co-location facilities.

To use our VLAN Extension service you'll need:

  • A Telstra cloud infrastructure virtual data centre in Australia
  • A Telstra Next IP® network connection
  • Any Telstra cloud infrastructure compute service
    • Virtual Server (Shared)
    • Virtual Server (Dedicated)
    • Managed virtual server (dedicated)
  • A terminating device compatible with our VLAN Extension service
    • Cisco CSR 1000V AppX Bundle
    • Cisco Nexus 3172 (available from late October 2014)

VLAN Extension cannot be used to connect two Telstra virtual data centres.

To accommodate VXLAN protocol encapsulation overhead, ensure your terminating device and any other inpath devices in your on-premises infrastructure have an MTU size of at least 1600 bytes.

First hop redundancy protocols such as HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol) and GLBP (Gateway Load Balancing Protocol) are not supported by our VLAN Extension add-on.

VLAN Extension can be configured in either a redundant or a non-redundant format. Redundancy of the communication connection is achieved by supporting the VLAN Extension tunnel with an identical second compatible terminating device at your on-premises end of the tunnel.

VLAN Extension enables you to progressively relocate servers across a shared subnet. It also allows you to migrate a server in a compatible format (e.g. OVF) to or from a virtual server (dedicated) service in cloud infrastructure. Note that VMware vMotion cannot be used for this purpose.

As part of your device set up, you'll need to create firewall rules to allow communication between VTEP IP endpoints on UDP port 4789.

For each extended subnet, you can control your traffic flow by locating your gateway either on our cloud platform, or in your on-premises infrastructure.

Whenever the gateway is located in our cloud infrastructure, for configuration purposes we require the first three useable IP addresses of each extended subnet.

Changing gateway location may disrupt access to your servers, and require configuration by both you and Telstra. Your service will be disrupted during a gateway change if your IP subnet is routed to both your on-premises infrastructure and cloud infrastructure environment.

A gateway change is available in two service levels, including a scheduled gateway change. A service level comparison is shown below.

Service feature Gateway change Scheduled gateway change

SMTP MAIL RELAY

All outbound email traffic originating from mail servers operating within the cloud must be sent through our SMTP mail relay service. SMTP mail relay is charged based on the number of email messages sent.

Configure your application using our SMTP mail relay details (which we send to you when your cloud solution is up and running). You're automatically charged for any emails sent through our servers.

EXTRA SERVICES

LOAD BALANCER SERVICES

Want to optimise your virtual server and network performance? Request load balancers for your private and public networks and control traffic between multiple virtual servers.

For more complex network configurations, you have the flexibility to customise the load balancer algorithm to divert particular traffic to different directions. The load balancer health check redirects traffic to other load-balanced servers if one of your virtual servers is not responding.

If your load balancer is facing the internet, we allocate a public IP address. If it's located in your private network, you assign your own private IP address.
