Community Cloud

A community cloud is one of the cloud infrastructures designed to meet the shared needs of multiple organizations. It allows them to access common resources and services while adhering to industry-specific requirements. The concept of a community cloud can be compared to a shared community garden where different people cultivate their produce on a common plot of land. Similarly, organizations with shared goals or regulatory needs can build and use a community cloud. This model offers a middle ground between public and private clouds, making it particularly appealing for the healthcare, government and education sectors. In this article, we’ll explore the architecture of community clouds some real-world examples and best practices to implement them effectively.

A community cloud enables organizations with similar operational and regulatory needs to collaborate on shared infrastructure. Unlike public clouds which cater to a broad audience or private clouds, which are typically exclusive to one organization, community clouds strike a balance by addressing collective goals. These clouds are often managed and operated either by the member organizations themselves or by a third-party provider. They provide cost-effective and secure solutions tailored to industries with strict regulations. For instance, during the COVID-19 pandemic sectors like healthcare and education adopted community cloud solutions to meet the increased demand for online operations and data security.

Community Cloud Architecture

The architecture of a community cloud is specifically designed to meet the shared needs of its members. These members are usually part of the same industry or organizational network and they collaborate to share resources such as data storage, applications and bandwidth.
