What Does Eucalyptus Mean?

Eucalyptus stands for Elastic Utility Computing Architecture for Linking Your Programs to Useful Systems. It is an open-source software framework that provides the platform for private cloud computing implementation on computer clusters. Eucalyptus implements infrastructure as a service (IaaS) methodology for solutions in private and hybrid clouds.


Eucalyptus provides a platform for a single interface so that users can calculate the resources available in private clouds and the resources available externally in public cloud services. It is designed with extensible and modular architecture for Web services. It also implements the industry standard Amazon Web Services (AWS) API. This helps it to export a large number of APIs for users via different tools.
