The Aurora MySQL replication features are key to the high availability and performance of your cluster. Aurora makes it easy to create or resize clusters with up to 15 Aurora Replicas. All the replicas work from the same underlying data. If some database instances go offline, others remain available to continue processing queries or to take over as the writer if needed. Aurora automatically spread
Garnet is a new remote cache-store from Microsoft Research, that offers several unique benefits: Garnet adopts the popular RESP wire protocol as a starting point, which makes it possible to use Garnet from unmodified Redis clients available in most programming languages of today, such as StackExchange.Redis in C#. Garnet offers much better throughput and scalability with many client connections an
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、
SREチームの長田です。 Tech Kayac Advent Calendar Migration Trackの15日目です。 S3バケットのバックアップ Lobiでは投稿された画像ファイルをS3に保存しています。 S3に保存しているだけでは、S3から誤って削除した場合に復元することができません。 主に読み書きするS3バケットとは別に、バックアップ用のS3バケットを用意し、そちらに画像ファイルのコピーを保存しています。 バックアップの仕組みを用意した当時はAWS内にこれを実現する機能がなく、自前のLambda functionでコピーを行っていました。 Backup S3 objects with Lambda function S3バケットに画像ファイルがPUTされたイベントをLambda functionに通知し、 対象ファイルをダウンロードして別リージョンにあるバックアップ用のS3バ

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
