7. #DevFest @tn961ir Technical debts I tackled in 2024 • Cloud Firestore ◦ nam5 (beta) (2018-07) ◦ cf. asia-northeast1 (2019-02) • Used for real-time application mainly targeted for residents in Japan, launched in summer 2019 ◦ Tightly connected with servers in Japan 😱😱😱 • > 100 ms in latency (~ 250 ms round trip) https://developers.googleblog.com/en/nosql-for-the-serverless- age-announcing-cloud-firestore-general-availability-and-update s/
8. #DevFest @tn961ir Replace w/Cloud Run • Cloud Run (TYO) + AlloyDB (TYO) • Direct client SDK (JP) + Firestore (nam5) vs
9. #DevFest @tn961ir Replace w/Cloud Run • Cloud Run supports for a single port. ◦ Limited due to spec of Knative serving. • Our new application: REST (HTTP/2) + WebRTC • 😔😔😔

11. #DevFest @tn961ir Replace w/Cloud Run GKE Autopilot • GKE Autopilot (TYO) + AlloyDB (TYO) • Direct client SDK (JP) + Firestore (nam5) 💡 💡 vs
12. #DevFest @tn961ir • GKE Autopilot (TYO) + AlloyDB (TYO) • GKE? ◦ = “Kubernetes” = hard way ▪ Version upgrade, fleet management, cost efficiency ◦ GKE Autopilot ▪ For both easy-to-use and full flexibility ▪ Autoscaling Replacing w/GKE Autopilot 🏗 🏗
13. #DevFest @tn961ir Summary • We are replacing an existing app based on Firestore (nam5) with apps with multiple ports hosted on GKE Autopilot instead of Cloud Run to minimize response time and data residency.
14. #DevFest @tn961ir TODOs for 2025 • Would like to develop more user-friendly real-time communication tool. • RAG-based app with Firebase Genkit.
