Containers!

• Easy to use !• Single Purpose environment!!

• But: non trivial once you move beyond a single host and applications need networking and other tooling!

Multi Host!

Weave!•  What? Portable application clusters made easy!

•  How? Service discovery & address automation via a secure, application orientated virtual container network!

•  Write the application and get the networking to do what you need not vice versa!

•  Minimum configuration, it just works !

•  Containers do not require specialist knowledge of other containers to connect to each other!
