- Why did Chatwork migrate from EC2 to Kubernetes?
- Issue 1: Deployment becomes unstable when the EC2 instance exceeds about 40 machines
- Issue 2: A rollback cannot be performed depending on the deployment status
- Kubernetes as a solution
- Kubernetes as an option
- Conclusion
Hello! This is cw-ozaki of the SRE Department.
The task of migrating PHP’s legend system from EC2 to Kubernetes that I have been involved with for some time has settled down a bit, so I wanted to share how this migration was made possible.
This article and the referenced articles to follow are the complete versions of the discussions held during the Japan Container Days V18.12 Meetup and the AWS Dev Day Online. I will also talk about some things related to the PHP Conference 2020 Re:born held in December, so I hope you are looking forward to it.
