Using Cloud Programming Interfaces

There are various programming APIs and language bindings are available for use with CERN private cloud. The support for these comes from the Internet communities rather than the CERN service desk. Different APIs have different levels of portability and compatibility which are included in the Notes section. General information about using APIs with OpenStack is available in the OpenStack API documentation. Software Development Kits are listed in the Developer documentation and SDK documentation. SDKs which work with OpenStack should work with the CERN private cloud unmodified.

Language Bindings

These are programming language specific APIs which can be used to access the CERN private cloud. These are suggestions of potential APIs to use rather than recommendations and the list is not exhaustive.

Note: Support for these APIs should be from the Internet communities, not the CERN Service desk

Programming API Language Links Notes
OpenStack SDK Python Documentation SDK for all OpenStack projects
Nova OpenStack API using python-novaclient Python Documentation
API provided by the OpenStack foundation. It is OpenStack specific but supports all of OpenStack's functions. This library is tested with the appropriate OpenStack release as part of OpenStack's standard release testing.
libcloud Python Web Site
Provides different cloud support including OpenStack. This can be useful for the same program talking to different cloud endpoints.
