DevOps & Cloud: Lessons & Stories
Lakmal WarusawithanaDirector - Cloud ArchitectureWSO2 Inc
How many of you think large scale distributed systems would be easy?
Rule of thumb for cloud deployment
Make the service scale
Make the deployment consistent
Understand all layers of the system
Monitor everything
Plan for failure
Break things under controlled conditions
Don’t deploy a server
● Server break, power fails
Don’t deploy a cluster
● Networks break, server break, power fails
Deploy redundant clusters
● Attempt to send clients to nearest serving cluster
● Use geodns / anycast ...
Never deploy poorly written code into cloud
Load balance is critical
Restartoring
If you can’t automate, don’t deploy it
Thank You
