Agile devops in the cloud
- 1. Agile Devops inthe Cloud Chamith J Kumarage Member, Cloud Devops Team WSO2
- 2. Outline • Automation • Monitoringand Analytics • Agile Delivery • Tools and Utilities • Scaling into the cloud • Devops at WSO2
- 3. Automation ● Tools thatperform functions otherwise done by humans. ● Task execution ○ Repetitive tasks ● Process flow ○ Connects tasks and decisions ● Decision trigger ○ When and Why to take action
- 4.
- 5. Automation contd. ● Designfor failure ● Validate every operation ● Enforce discipline ( and process ) ● Accelerates execution ● Improves agility Be the automator, without being automated!
- 6. Monitoring and Analytics ●Discovery ○ Normal vs abnormal ● Communication ○ Do you understand what it say? ● The big picture ● Root cause analysis Hint: #monitoringsucks
- 7.
- 8. Agile Delivery ● Discoverability ○Create, Test and Deploy in smaller increments ● Quality ○ Frequent testing, Catch bugs when they are small ● Operations is the first customer ● Continuous delivery or Continuous deployment
- 9.
- 10. Tools and Utilities ●Shorten the pipeline from dev -> production ● Enforce best practices and standards ● No need to reinvent the wheel ● Each tool can be a component of a framework ● Documentation is a must ● Has to comply with the ‘bus monkey’ test
- 11. Scaling into theCloud ● Automatic failure detection and prediction ● Self healing at all possible levels ● Use native cloud offerings ● One-Click operations ● Design for failure ● Kill instance test (chaos monkey test) is a must!
- 12. Devops at WSO2 ●Focused on “one-click” deployments ● Use Puppet and a few homemade tools for automation ● Icinga and Heartbeat Checker for first-level monitoring ● Heavily use Python for automation ● Ruby to extend Puppet features ● Working on getting Continuous deployment to action We are not there yet :)
- 14. Devops at WSO2contd. ● Primarily use AWS infrastructure technologies ● ~100 EC2 instance ● ~15 RDS instances ● ~140 services ● Ownership: ~65 resources/person
