 • Platform: Developer productivity & experience • SRE: Production and its operation (ROAD(*)) (*) Response, Observability, Availability, and Delivery. See The ROAD to SRE. There are many ways to introduce Site… | by Bruce Dominguez | Medium
6. Embedded SRE
 • Support product teams to improve service reliability • Spread SRE practices across the organization

8. The Works
 • Search Infra Team ◦ The search is one of the critical functionality of the Mercari app where we connect sellers and buyers. They receive the largest traffic, and (because of this) the search infra team frequently adds/releases features. So the service has high-reliability demand. The SRE member joined the team and worked on supporting production release, building the benchmarking system to ensure avoiding latency delegation, optimizing the cost, reviewing and improving the SLI/SLO, and so on. • Monolith API Team ◦ While we’ve been working on microservice migration but we still have the original monolith API and it’s critical for our product. It was running on the on-prem but currently, we are working on migrating it to Google Cloud where the microservice is running. Since we have the knowledge to run services reliably in a cloud-native way, we joined the team and supported its migration. Since the Monolith API is using a different monitoring stack, we are helping to migrate the same stack as other microservices so that we can have seamless tracing between them.
