The diagrams below show the different types of cloud-based system architectures that you can build in Rackspace using their public cloud or a hybrid architecture. Some of the diagrams are strictly cloud-based architectures using Rackspace Cloud Servers while others are hybrid architectures that leverage both Rackspace's Public Cloud and Managed Dedicated hosting services.
The architecture diagrams below show the different types of reference architectures.
In this example, Rackspace Cloud Servers are used for each server in the standard three-tier system architecture. ServerTemplates published by RightScale are currently available in the MultiCloud Marketplace to launch each type of server. The Apache/HAProxy load balancer supports SSL termination. Data is stored locally on a single database Cloud Server. Continuous backups of the database are saved as LVM snapshots to the specified cloud storage option. (e.g. Cloud Files Container)
In this example, Rackspace Cloud Servers are used for the application and database tiers, but Rackspace's Cloud Load Balancing service is used for load balancing. SSL termination is currently not supported by CLB.
Rackspace supports hybrid cloud architectures that combine cloud servers and non-cloud servers using RackConnectTM. In the example below, Rackspace Cloud Servers are able to connect to a database server that's located in Rackspace's Managed Hosting data center.
You can also use Rackspace's Cloud Load Balancing service instead of using cloud servers as dedicated load balancers. SSL termination is currently not supported by CLB.
If you want a higher performance load balancing solution that a CLB you can also use a Rackspace F5 Load Balancer.
