Big Cloud is the cloud computing software stack developed by  to support ‘s operation platform and provide services to its more than 600 million customers.

BC-EC, Big Cloud Elastic Computing, chose  as its core component to manage and schedule the virtualization infrastructure in 2008. Since then, we are glad to see OpenNebula to be more full-fledged each day. And BC-EC, matured with OpenNebula, was used both in China Mobile’s internal business and ready to provide public service.

BC-EC includes 3 parts: web portal providing self-service entry, front-end management service providing service and operation management, user management and billing etc, and service database.  Front-end can provide similar functions as OZone to manage several OpenNebula back-ends.

This cloud includes 1000 servers, 700 servers of those will provide virtual machine computing service based on BC-EC and another 300 servers will provide cloud storage based on Big Cloud’s object store system, named Onest.
