An anonymous reader writes: Cloud computing startup Mesosphere has opted to open-source its data center management platform. This move is backed by Microsoft, Hewlett-Packard Enterprise, Cisco Systems and roughly 60 other tech partners. The three-year-old San Francisco company's datacenter operating system (DCOS) was built as an operating system for all services in a data center to function as one pool of resources. Capabilities include the quick, app store-like installation of more than 20 complex distributed systems, including HDFS, Apache Spark, Apache Kafka and Apache Cassandra, Mesosphere said in an announcement. Although some of the company's technologies were already available as open source, others were propriety until now. Mesosphere said it welcomes additional enterprises interested in partnering on this open source project.Wired has more details on this in its slightly enthusiastic report titled You want to build an empire like Google's? This is your OS.
