We built Weave Net to make it easy to network your Docker containers however you like. At its core, Weave Net is powered by an eventually-consistent, partition-tolerant, completely decentralised mesh. We're packaging this technology as Weave Mesh, so that you can build your own distributed applications with the same simplicity and reliability as Weave Net. In this talk we will explain the theory behind Weave Mesh, some of the key features we learned were important, and demonstrate some exciting use-cases, like distributed caching and state replication.
