It provides strategies for implementing Continuous Integration/Continuous Deployment (CI/CD), automated infrastructure management, and monitoring solutions. The text also highlights the importance of designing systems for failure and encourages frequent deployments to reduce failure rates.
DevOps @ Namshi
- 3. DevOps is mainly an advocacy that encourages collaborative working relationship between development and IT operations in order to speed up planned work while increasing reliability, stability and security of production environment. -Gene Kins, author of The Phoenix Project
- 4. It works on my machine...
- 5. It’s not the server, it’s your code...
- 6. Dev Or Ops + I spend 70% of my time waiting to get my code to production. + I don’t know who to escalate to. + I’m constantly firefighting. + Build system is not realistic.
- 7. Trying to work on Namshi production systems about 4 years ago
- 8. Sample Strategy for DevOps Setup CI/CD server (e.g jenkins, travis-ci, bamboo, etc) Develop automated builds (e.g docker, jenkins, bamboo, etc) Automated deployments (docker, jenkins, capistrano, fabric, chatops, etc)
- 9. Sample Strategy for DevOps Infrastructure as a code Automated infrastructure build/tear-down (terraform, cloudformation, etc) Configuration management (saltstack, ansible, puppet, chef, etc) Version-controlled infrastructure code Pull requests Automated monitoring & alerts (icinga, sensu, prometheus, grafana, appdynamics, newrelic, etc)
- 10. Sample Strategy for DevOps Central logging (ELK, graylog, sematext, splunk, etc) Cross-discipline team Automate all things (cron, jenkins, lambda, etc)
- 11. Design a system with the mindset that it’s going to fail
- 12. Stateless applications Blue-green deployments Immutable systems Rollback strategy Cattle vs pets Design a system with the mindset that it’s going to fail
- 13. Deployments are scary because we don’t do it often
- 14. At Namshi, We deploy all the time! The more you deploy, the lesser the failed deployment attempts
