Cloud federation, also known as a federated cloud, is an implementation of multiple cloud computing infrastructures in a unified cloud environment. A cloud federation combines IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service) services from a diverse group of cloud computing service providers to meet the business requirements. A cloud federation has a single authentication and authorisation framework for cloud providers, allowing them to distribute workloads across the globe, exchange data with different networks, and implement security measures.
Points to Remember
- Cloud federation agreements often allow cloud providers to sell and rent computing resources and components to another service provider.
- Cloud federation may be beneficial for both consumers and cloud providers. A federated cloud enables provider the scalability, availability and flexibility in services while cloud providers can earn revenue from the computing resources that would otherwise be unused.
