Introduction of a new Nova REST API: Why we need to use Nova v2.1 API

admin Talks

OpenStack Summit Vancouver, 2015,

    Vancouver Convention Centre, Monday, May 18 • 2:00pm – 2:40pm

OpenStack projects provide their services via REST APIs.
CLI (commands: nova, keystone, etc) and GUI like Horizon also operate
OpenStack services via REST APIs. In addition, cloud service providers
become to provide REST APIs to external world, and cloud users become
to use these APIs directly on their own applications to use the best
cloud service at the time. So the world is moving to interoperability.

One of OpenStack core projects Nova also provide many services via its
REST APIs. However, current Nova API (v2) contains problems like lack
of input validation, inconsistent interfaces and difficult to add a new
API implementation, etc.
To solve these problems, we have developed a new REST API called “v2.1”
in Juno and Kilo development cycles. By using v2.1 API in many cloud
services, we will be able to get safer services and interoperability will
become easier.

In this session, you will know the outline of Nova v2.1 API, its merits and
how to use v2.1 API for users and cloud service providers. In addition,
we are developing new features based on v2.1 API, so you will know next
features also. I hope this session helps you deploy/use better OpenStack
