Cloud computing has grown at a significant rate over the past few years. While cloud computing alleviates much of the hardware management challenge, many researchers and educators have difficulty embracing the aspects of cloud computing that make it unique and preferred for many activities. Among the many features cloud computing brings, elastic computing - resources on demand, may be one of the most appealing. A purpose-built virtual machine can be built quickly and easily as a first step. Taking the example further into scripted launching of more resources as necessary is the logical next step. The next step can use elastic computing techniques to create virtual clusters on demand, bringing compute resources into existence when needed and removing them when they are no longer necessary. This elasticity enables gateway providers and researchers to make efficient use of limited resources, while providing a resource for HPC-style jobs that isn't dependent on external HPC resources.
While modest cloud-based virtual clusters won't replace traditional HPC resources for jobs that require high-speed interconnects or large core counts and high memory profiles, many smaller gateway, research, and education projects might benefit from the highly customizable and configurable, programmable cyberinfrastructure afforded by cloud computing environments. This tutorial will explore the basic methods required for interacting with elastic computing environments. It will then show a hands-on approach to creating virtual clusters in an OpenStack environment, including the necessary steps to make the cluster elastic, to take full advantage of the cloud environment.
