Summary

InfluxData's platform team undertook a significant architectural transformation by migrating from a Go-based microservices setup to a Rust monolith, aiming to simplify infrastructure and development while enhancing safety and maintainability. The transition supported a new administrative UI for InfluxDB Cloud Dedicated and aligned with plans to rewrite the InfluxDB database engine in Rust. The switch to Rust brought benefits such as a stronger type system, complete and safe error handling, and explicit mutability, which collectively reinforced software correctness and reduced bugs. The migration employed a "strangler fig" approach, allowing for endpoint-by-endpoint transition without downtime, facilitated by integration tests ensuring identical logic between the old and new systems. The use of domain-driven design and hexagonal architecture promoted modularity and flexibility, enabling the team to ship a new V1 REST API alongside the existing gRPC and REST services efficiently. This systematic approach, completed by a team of five in three months, demonstrated increased development speed and software safety due to the strategic use of Rust and upfront design planning.
