At the 2013 OpenStack Summit in Hong Kong, Norifumi Matsuya (Technical Director at Yahoo! Japan) described exactly how they’re using OpenStack in their efforts.
By the end of 2014, 80% of Yahoo! Japan’s 50,000 Virtual Machines will be managed by OpenStack.
Originally, they were designing their own private cloud system in-house, but because the development of OpenStack was amazingly fast, they decided that switching to OpenStack would be a wiser choice.
In order to perform the data center life-cycle management, abstraction of all the hardware is necessary. They plan to use OpenStack for this hardware abstraction, and then migration can be performed between the abstracted OpenStack clusters.
