RightScale Conference Santa Clara 2011: ServerTemplates are the innovative "secret sauce" of the RightScale Cloud Management Platform. Slice up existing configurations into your own custom blueprints for cloud servers in order to easily architect, launch, manage, and monitor multi-server deployments. A majority of the 40,000-plus RightScale ServerTemplates were created from scratch by our customers. We'll share best practices for developing, testing, and maintaining your own custom ServerTemplates.

- PAVELOverview: Today’s webinar focuses on great and not so great workloads for the Cloud and our experiences from in the field!
- First, a point to drive home. Live above the cloud. Live above the image. Configure vanilla machines at runtime. The flexibility of the cloud ends at the image.
- “The ServerTemplate methodology is great because it forces us to script out our configurations, which are best practices anyway.”
- You’ll get all the machine monitoring out of the box – cpu, disk, etc. Input to monitor any other stuff you install… move this script to the end of the template if you do.
- You might just find exactly what you need.Or you can find snippets of what you need and build it and test it. Minimize external dependencies by attaching files or anything you need to compile as a .tar.Finally, we have partners that have put up a lot of the software for you. And they build test it everyday.
