Basic Cloud Instance

Basic Cloud Instance

A basic cloud instance can be provisioned through the order page.

Basic Networking

In a Basic Networking setup, the Guest Instances use the same IP range as the underlying CloudStack and Hypervisor architecture. When designing your IP Schema, allow sufficient IP Addresses to cater for all of your CloudStack infrastructure including the Guest Instances. Consider using an IP Range such as 192.168.0.0/20 for each Zone, as this will provide over 4,000 addresses IPs per Zone. Warning:, If you use a /16 subnet for your first Zone, there would be no more Private IP Addresses left for additional Zones!

IP addresses will need to be reserved for each POD, and a Guest IP Range assigned during the initial configuration of the Zone. Every Host, System VM and Guest Instance within the whole Cloud must have a unique IP Address.

Each pod in a basic zone is a broadcast domain, and therefore each pod has a different IP range for the guest network.

Guest, Management and Storage are common to Basic and Advanced Networking, Public Traffic is only present in an Advanced Network configuration.

  • Public IP address is obtained from a dhcp server.

  • Instance must always have its networking set to DHCP.

  • Stopping and Starting VMs Once a VM instance is created you can stop, restart, or delete it as needed. In the admin UI, click Instances, select the VM, and use the Stop, Start, Reboot, and Destroy links.

  • Remote Access to VMs The user is able to access virtual machine console through the web management UI.

  • End User Interface The end user UI is an AJAX-based UI available in popular browsers including IE7, IE8, IE9, Firefox 3.5+, Firefox 4, Safari 4, and Safari 5.

  • We offer a number of features for end users: Service Offering Description, Template Management, Virtual Machine Management, Network Management, Event Logs, Snapshot Management, Dashboard

  • Hardware fail over - when hardware devices on the host start to fail, guests can be safely relocated so the host can be powered down and repaired.

  • Snapshots Your VMGuest supports snapshots of disk volumes. Snapshots are a point-in-time capture of virtual machine disks. Memory and CPU states are not captured. Users can create snapshots manually, or by setting up automatic recurring snapshot policies. Users can also create disk volumes from snapshots, which may be attached to a VM as any other disk volume. Snapshots of both root disks and data disks is supported.

   

Provides AWS-style networking with a single network where each VM instance is assigned an IP directly from the network. Guest isolation is provided by security groups (IP address source filtering)

Advanced Cloud Instance

 

Testlabs Australia Advanced Cloud Instance Provides a sophisticated network topology. This network model provides the most flexibility in defining guest networks and providing custom network offerings such as firewall, VPN, or load balancer support. Our Advanced Cloud is located in Melbourne CBD for all your hosting needs.

The traffic types are management, public, guest, and storage traffic.

 

The Guest VMs communicate with each other over a network that can be referred to as the guest network. This network is isolated and the administrator reserves VLAN ranges to provide isolation.

  • Load balancing - guests can be moved to hosts with lower usage when a host becomes overloaded.

  • IP Load Balancing The user may choose to associate the same public IP for multiple guests. The system implements a TCP-level load balancer with the following policies: Round-robin,Least connection,Source IP

  • VPN VMGuest provides a L2TP-based VPN service to guest virtual networks. Clients native to Windows and Mac OS X may be used to connect to the guest network. The user is responsible for creating and managing users for their VPN.

  • Snapshots Your VMGuest supports snapshots of disk volumes. Snapshots are a point-in-time capture of virtual machine disks. Memory and CPU states are not captured. Users can create snapshots manually, or by setting up automatic recurring snapshot policies. Users can also create disk volumes from snapshots, which may be attached to a VM as any other disk volume. Snapshots of both root disks and data disks is supported.

  • Port Forwarding A port forward service is a set of port forwarding rules that define a policy. A port forward service is then applied to one or more guest VMs. The guest VM then has its inbound network access managed according to the policy defined by the port forwarding service.

  • Firewall Rules By default, all incoming traffic to the public IP address is rejected by the firewall. To allow external traffic, you can open firewall ports by specifying firewall rules.

  • Stopping and Starting VMs Once a VM instance is created you can stop, restart, or delete it as needed. In the admin UI, click Instances, select the VM, and use the Stop, Start, Reboot, and Destroy links.

  • Remote Access to VMs The user is able to access virtual machine console through the web management UI.

  • End User Interface The end user UI is an AJAX-based UI available in popular browsers including IE7, IE8, IE9, Firefox 3.5+, Firefox 4, Safari 4, and Safari 5.

  • We offer a number of features for end users: Service Offering Description, Template Management, Virtual Machine Management, Network Management, Event Logs, Snapshot Management, Dashboard

  • Hardware fail over - when hardware devices on the host start to fail, guests can be safely relocated so the host can be powered down and repaired.


In an Advanced Networking setup, each Account is allocated the following:

 

Public IP, this is a live Internet Address and is assigned to their Virtual Router

 

Guest IP Range, for example 10.1.1.0/24

 

VLAN ID for the Isolated Guest Network

 

The default Guest IP Range is the same for all Accounts within a Zone, however it is possible for a Root Administrator to assign custom IP ranges to different Accounts.

 

Guests Instances within an Account communicate with each other and their Virtual Router via their own dedicated VLAN. Guest Instances can be running on any Host within the Zone, the VLANs on the Layer 2 Switches ensure they can always communicate by using VLAN Trunking.
