This article series will help you understand what cloud computing is and how it works, and how IBM products can help you succeed with a cloud strategy.
This first article begins by examining some of the technologies that make cloud computing possible, and then explains the basics of cloud computing.
Workload Deployer supports three types of hypervisors: PowerVM®, VMware ESX, and z/VM®. Workload Deployer also enables you to manage multiple hypervisors or cloud groups as isolated pools of hypervisors of the same type.
IBM PureApplication System embeds the capabilities of IBM Workload Deployer and offers the same Web 2.0 interface and pattern modeling technology, but it also integrates the hardware, the hypervisors, the software, and the networking resources needed to support the cloud environment.
IBM PureApplication System is called an Expert Integrated System (EIS) because it includes everything needed for the cloud in a single box. As Figure 1 illustrates, with Workload Deployer, you bring your own cloud into the picture, whereas, with IBM PureApplication System, you get a cloud-in-a box, which also incorporates Workload Deployer technology. Both Workload Deployer and IBM PureApplication System enable the rapid adoption and deployment of Infrastructure as a Service and Platform as a Service offerings.
