こんにちは、滝澤です。 前回の記事『WireGuardによるマルチクラウド構成VPNの事例紹介』に引き続き、社内事例を紹介します。 弊社ハートビーツではMSP（Managed Service Provider）サービスの可用性向上のために、社内基盤をマルチクラウド構成で運用しています。 複数のクラウド拠点のネットワーク間をWireGuardというVPNトンネルのソフトウェアで接続しています。 さらに、リレーショナルデータベース管理システムにはMySQLを利用しており、MySQLのレプリケーション機能の一つであるGroup Replicationを使って拠点内および拠点間における冗長化を行っています。 今回はこのMySQL Group Replicationの利用事例を紹介します。 行っていることをまとめると次のようになります。 マルチクラウド構成（Azure, AWS, GCP）において、
Jeremy L. England "Statistical physics of self-replication"「自己複製の統計物理学」を読んだ話。 - sun_ek2の雑記。

Due to the immense generation of data, scalability has become one of the hottest topics in the field of databases. Scalability can be achieved horizontally or vertically. Vertical scalability means adding more resources/hardware to existing nodes to enhance the capability of the database to store and process more data, for example, adding a new process, memory, or disk to an existing node. Every D
