A propos de "Virtual Application Patterns"...
Extrait de l'article "I've virtualized my systems, isn't that a Cloud ?" [Joe Bohn, Thoughts on Cloud]
[...] We took the abstraction up a level higher and introduced application virtualization last year in our IBM Workload Deployer private cloud management solution. By application virtualization I mean providing the capabilities to abstract the application from the underlying infrastructure such that it can be elastic, highly available, and provide agility across a pool of application infrastructure resources.
This type of application virtualization is built into our virtual application pattern (hence the name) – an application-centric way of defining, provisioning, and managing the complete lifecycle of your application. Features such as elasticity of the application itself and shared services to support non-functional requirements are delivered in policies using common metrics such as response time service level agreements (SLA). Requirements that are common for nearly any application, such as high availability, are “baked” right into the solution without any definition required.
Virtual application patterns support specific types of applications in a highly integrated solution – integrated both on the front-end user interface, and on the back-end implementation of the running systems. Management is from an application perspective – not focused on the various middle components that are necessary to support the application. This a true platform as a service (PaaS) solution where IBM Workload Deployer dynamically builds the necessary platform infrastructure to support the specific needs of the application.[...]
