Service ownership is becoming a best practice for teams looking to innovate while maintaining the level of reliability that customers expect. Service ownership means seeing the service through its entire lifecycle. In short, it means you build it, you run it. You’ll be responsible for the service’s security, reliability, performance, and quality.
This doesn’t mean you won’t have help from SREs to optimize or automate toil. It does mean that, as a developer, you need to build with quality in mind as you’ll be on call if your code breaks.
