Walmart has released the OneOps cloud development platform under an open source license. According to the company, it can help prevent vendor lock-in, and it supports the DevOps culture at WalmartLabs.
"This is good news for developers who need technology that can continuously manage and monitor the applications they develop when it's deployed in the cloud," blogged Jeremy King from WalmartLabs. "It's great news for companies who have considered switching cloud providers but experience the 'Hotel California Effect,' where they can 'check out but never leave' their cloud provider."
WalmartLabs acquired the platform as a service when it bought OneOps in May 2013.
