1. A system comprising: a datacenter environment, the datacenter environment comprising a first plurality of physical server computers and a second plurality of physical server computers, each physical server computer having a processor, a memory, an associated physical mass storage, a network connection, and a container runtime; wherein the container runtime further comprises: a plurality of isolated containers, each container including one or more application instance processes, wherein the one or more application instance processes are configured to directly communicate via a direct communication link with the physical mass storage associated with the physical server computer; a message bus, wherein the message bus is communicatively coupled with the network connection and with the plurality of isolated containers, and wherein the message bus is operable to send and receive application programming interface (API) messages via the network connection or via a connection with a container, and distribute the API messages to individual associated containers or to other servers via the network connection; wherein the containers within the first plurality of physical server computers do not persist state generated by application instance processes on the first physical mass storage associated with the first plurality of physical server computers; and wherein the containers within the second plurality of physical server computers persist state generated by application instance processes on the second physical mass storage associated with the second plurality of physical server computers.
