Private Cloud Strategies

Private cloud management requires tools, such as OpenStack, to create virtualized com-
pute resource pools and provide a user self-service portal, security through authentication,
dynamic resource allocation, and tracking and troubleshooting.
Forrester Research defines internal clouds as “pools of virtualized machines that can be
built upon either virtual server or high-performance computing grid foundations and can
be operated to the specific security and process requirements of the business.”

Private cloud environments are typically organized in terms of portable workloads. The
management tools are usually service driven because the private cloud is highly virtualized.

Community Cloud Strategies

A community cloud is generally not managed in its entirety by one single institution or
organization. Instead, parts of the cloud are managed by various responsible parties
involved in a joint project or sharing a common concern.
Institutions such as universities and research labs generally have focused groups to deal
with issues related to the infrastructure management of the community cloud. These groups
collaborate with groups of other partner universities or research labs to achieve set goals,
diagnose problems, resolve issues, and prepare contingency plans to adopt in the event of a
large-scale failure. However, different partners may not share the same micro-level concerns,
such as time limits to fix an issue, prioritizing tasks, and communicating and reporting
progress to other institutions.
