Fast Application Provisioning for Cloud Computing

The rapid growth of cloud computing combined with improvements in virtual computing have led to large numbers of servers running many LPARs. The time required to create and install an LPAR is a major concern for cloud computing customers and cloud providers. A choice point for customers shopping for cloud services is how quickly an LPAR can be provisioned and the amount of customization available at creation time. Since non-homogeneity among LPARs on a single CEC is a standard in a cloud environment, the provider must offer a way to quickly provision a variety of images to be competitive in this environment. Install time is easily the largest part of the provisioning time for an LPAR.

The method described in this article uses a combination of SSDs and a RAM file system (RAMFS) to greatly reduce the time required to install an LPAR.

Configuring an enterprise class server in a cloud environment usually involves installing an operating system, middleware and applications. The install is usually performed from a network install server to the new LPAR's HDDs. The performance of these installations is dictated by 3 major factors:
1) reading the files from the HDDs from the install server.
2) transferring the files over the network
3) writing the file to the LPAR's HDDs

Installations take on the order of 30 to 60 minutes, depending on the OS, middleware and applications being installed.

This time can be reduced to less t...
