When we talk to IT organizations about using Eucalyptus to set up a private or hybrid cloud, they often ask "How do I get started?" To answer that question, we've published a series of Cloud Reference Architectures which are specific to common use cases deployed in the field. Our Dev/Test Reference Architecture illustrates an example framework for building a private or hybrid cloud for development and QA testing purposes.
The Gap Between Dev and Ops
In many IT organizations, a gap exists between developers and the IT operations team. Developers are trying to create new applications and move them into production quickly. But there are often delays in provisioning the infrastructure and resources that developers need. This gap often leads to lost productivity and time to market delays.
Eucalyptus offers an AWS-compatible private and hybrid cloud solution which provides developers with the same flexibility and agility they've come to expect from the public cloud, while still allowing IT operations teams to maintain control and costs. The Eucalyptus cloud platform features self-service resource provisioning to enable developers and QA engineers tonstreamline workflow processes and do their work quickly and efficiently. Developers don't need to submit an IT ticket and wait for weeks to get what they need. Developers can quickly provision and configure the compute, storage, and networking resources they want on demand.
Cloud Reference Architecture Serves as a Deployment Template
So where does the Cloud Reference Architecture fit in? The Cloud Reference Architecture provides a deployment template for IT ops teams to assist them in setting up a Eucalyptus private or hybrid cloud. The Cloud Reference Architecture provides the resouce details they need and the recommended deployment model for their specific use case (in this case, Dev/Test).
This is important for two reasons: First, it prescribes a bill of materials and how to deploy the Eucalyptus cloud platform on it. Second, the Cloud Reference Architecture provides a "recipe" for the bill of materials needed to run the cloud.
In the case of a Dev/Test environment, Infrastructure as a Service (IaaS) provides the automation for provisioning and de-provisioning resources as application and workload demand ebbs and flows. The Cloud Reference Architectures for Dev/Test Small, Dev/Test Large, and Dev/Test Large with VMware, provide design choices for the IaaS solution, including physical resources required and a deployment topology.
The Cloud Reference Architecture also outlines technologies commonly deployed with Eucalyptus to provide a complete IaaS solution – such as configuration management, monitoring, and workflow management.
Dev/Test is a great place to get started with Eucalyptus and the Cloud Reference Architecture provides you the tools to start.
