This document discusses Weave, a tool that allows application portability across infrastructure by enabling container networking across hosts, data centers, and clouds without application changes. Weave provides service discovery, address automation through a secure virtual network, and DNS for containers. It allows containers to connect to each other without specialist networking knowledge and works the same way across single or multiple hosts, data centers, or clouds. Upcoming features for Weave include IPAM, faster data paths, and enhanced DNS integration.

- 2. Application ! Portability Independent ! of Infrastructure?!
- 3. Containers!
- 4. Have we not heard this before?!
- 5. Containers! • Easy to use ! • Single Purpose environment! !
- 6. Single Host!
- 7. Containers! • Easy to use ! • Single Purpose environment! ! • But: non trivial once you move beyond a single host and applications need networking and other tooling!
- 8. Multi Host!
- 9. 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!
- 10. Weave Info! • Launched Sept 2014! • Current release (0.9.0) launched in Feb 2015! • 60K Downloads of current release! • 160K Weavetools containers! • ~3150 Stars on Github! https://github.com/weaveworks/weave! ! !
- 11. Weave! • Connect services across hosts! • Across data centres! • Across clouds!
- 12. Weave! • Connect services across hosts! • Across data centres! • Across clouds! With the same interface and ! no application changes!
- 13. Single Host!
- 14. Multiple Hosts!
- 15. Multiple Clouds!
- 16. WeaveDNS! • DNS for containers! • Part of Weave! • nothing to configure! • nothing to maintain! • no change request to submit when you need a new name…. !
- 17. WeaveDNS! • Just launch your containers with a hostname! • WeaveDNS will do the rest! • Application is addressable by a known hostname! • WeaveDNS can do simple round robin load balancing efficiently as you are in a constrained network! • Easy to query via dig for information that load balancers or other tools may need!
- 18. WeaveDNS!
- 19. Upcoming! • IPAM ! • Fast Data Path! • WeaveDNS Enhancements & Tighter Integration! • Docker Plugins! • …. your suggestions? pull requests?! !
