Microsoft is not always associated with the open source movement but to think they no longer play nice is a mistake. Microsoft is a big backer of Open Source Software (OSS) and is putting significant resources behind it. Microsoft’s Azure platform works seamlessly with open source especially when it comes to cloud development interfaces and tools. In 2016, Mark Russinovich, CTO of Microsoft Azure, gave the keynote address at DockerCon; telling attendees that 33% of Azure virtual machines were running Linux. That’s up from 25% in 2015, when Microsoft joined the Cloud Foundry – a popular PaaS architecture that’s becoming the DevOps platform of choice for enterprises. Other Cloud Foundry members include the original founder Pivotal, Cisco, Google, IBM, SAP and Suse.
