Yesterday saw the announcement of the Open Container Project in San Francisco. It is a Linux Foundation project that will hold the specification and basic run-time software for using software containers. This is all "A Good Thing™."
The list of folks signing up to support the effort contains the usual suspects and this too is a good thing: Amazon Web Services, Apcera, Cisco, CoreOS, Docker, EMC, Fujitsu Limited, Goldman Sachs, Google, HP, Huawei, IBM, Intel, Joyent, the Linux Foundation, Mesosphere, Microsoft, Pivotal, Rancher Labs, Red Hat, and VMware.
