This conference talk explores the long-term value of gRPC as a communication protocol for backend applications based on five years of practical implementation experience. Follow Konstantin Ostrovsky from Torq.io as he shares his journey of fully adopting gRPC for both backend-to-backend and frontend-to-backend communication. Discover the challenges encountered, successes achieved, and why—after half a decade—he remains convinced it was the right architectural decision. Gain valuable insights to inform your own protocol selection process, whether you're already using gRPC or considering it for your projects. The presentation provides a candid assessment of gRPC's practical benefits and limitations based on real-world implementation experience.
