Hybrid Cloud Computing
Eucalyptus Drives Innovations in Hybrid Cloud Software
Hybrid cloud computing means accessing the combined resources of one or more public clouds and one or more private clouds in a way that is seamless and transparent. Hybrid clouds typically use a shared API to enable hybrid operation. With hybrid cloud computing, organizations can utilize the cost benefits of a public cloud and when needed, protect confidential data in a private cloud.
Eucalyptus is a Linux-based open source software architecture that implements private and hybrid cloud computing within an enterprise’s existing IT infrastructure. Engineered to emulate Amazon Web Services (AWS), Eucalyptus interacts seamlessly with Amazon public cloud services, including EC2 and S3, without software modifications. This kind of hybrid cloud computing allows IT organizations to quickly “cloudburst” into the public cloud space without purchasing additional data center hardware during very large spikes in enterprise resource demand.
Private-public cloud interoperability is also critical to a hybrid model. If the private cloud triggers a public cloud deployment automatically, the application code and data must be portable between the two domains.
