This document summarizes a microservices meetup hosted by @mosa_siru. Key points include:
1. @mosa_siru is an engineer at DeNA and CTO of Gunosy.
2. The meetup covered Gunosy's architecture with over 45 GitHub repositories, 30 stacks, 10 Go APIs, and 10 Python batch processes using AWS services like Kinesis, Lambda, SQS and API Gateway.
3. Challenges discussed were managing 30 microservices, ensuring API latency below 50ms across availability zones, and handling 10 requests per second with nginx load balancing across 20 servers.
今年3月に発売されたFINAL FANTASY XV WINDOWS EDITIONでは、マルチプレイ実装にPhoton Serverを採用しています。コンソールのバージョンとも親和性が高く、なんと約1週間で動作するところまで到達しました!
本セッションでは、FF15内でのパケット送信のカスタマイズやマルチプレイ特有の実装、バックエンドサーバーの構成などのご紹介に加え、Photonのイントロダクションと最新情報も合わせてご案内いたします。内容の濃い45分間、ご期待ください!

REALITYアバターを様々なメタバースで活躍させてみた - GREE VR Studio Laboratory インターン研究成果発表gree_tech
?
The document outlines the research presentations from an internship program at GREE VR Studio Laboratory. The presentations covered topics like motion capture techniques that could be used in metaverses, generating emotive expressions from sound, and representing metaverses using augmented reality. One presentation proposed a way for users to virtually travel the world together by exploring street view locations and taking photos with their avatars.
The document discusses a quality improvement project at Reality Inc. to reduce app startup time. It began with measuring startup sequences on iOS and Android to identify bottlenecks. This showed networking requests and initializing distributions were slow. Performance was then measured in user environments using Firebase and GCP tools. Startup times of over 6 seconds were found. The project aims to parallelize processes, remove unnecessary tasks, and speed up networking to reduce startup time through ongoing measurement and optimization.
This document introduces two operational support tools for making Cloud Spanner more convenient: Spanner Warming Guy and Spanner Up-Down Guy.
Spanner Warming Guy is a tool that performs warmup of Cloud Spanner before releases. It can add load to Spanner through SELECT queries alone and automatically adjusts the number of SELECT bots.
Spanner Up-Down Guy is a tool that auto-scales the number of nodes in Cloud Spanner. It periodically executes Cloud Functions to adjust the node count according to a pre-defined schedule or the load situation. It can gradually decrease nodes to reduce costs.
