Rackspace has implemented an update for its OpenStack private cloud service which adds a 99.99% SLA to enterprise customers.

The service level agreement is for the OpenStack API, and the firm said it will deliver increased scalability to hundreds of nodes and DevOps automation services for application lifecycle management.

Nigel Beighton, VP technology at Rackspace, said: "This is an important indication that OpenStack is maturing fast. Today businesses don’t want to be tied into proprietary systems that stifle innovation and agility, so the principles of an open source platform that is easy to implement, massively scalable and feature rich is increasingly attractive.

"The fact that we are also offering unprecedented API uptime guarantees for our private cloud is testament to our faith in the capability of the platform."

The improvements will be initiated for UK customers in October.

Launched in 2011, the Rackspace Private Cloud was designed and built by the OpenStack experts who co-founded OpenStack and run one of the world’s largest OpenStack-powered clouds.
