�  Pros: �  Simple �  Non-intrusive

�  High compatibility (native solution) �  Programmable

�  Cons: �  No role-based discovery �  Necessary service restart

VisualOps Implementation

Clustering

�  My containers on a cluster of machines!

�  Goals �  Efficiency

�  Reliability �  Availability

�  Container’s location is becoming dynamic …

Swarm

�  Part of the Docker “tool chain”

�  Act as a “proxy” to the multiple Docker daemons

�  “Speaks” Docker API

�  Introduce new services discovery solution

�  Compatible with other services discovery solutions (API)

DuneOS
