Service Overview

CacheStore(DBaaS) is a service that provides the in‑memory based data stores Redis OSS and Valkey. Samsung Cloud Platform provides an environment that can automate the installation of Redis OSS and Valkey through a web‑based console and perform management functions for operation.

CacheStore (DBaaS) provides a Sentinel method consisting of a Master server that performs read/write operations and read-only Replica servers that replicate Master data. Sentinel checks the status of DB servers where the engine is installed, and if a failure occurs on the Master server, it automatically failovers the Replica servers to become the Master server. Additionally, to prepare for issues with the DB server or data, it offers a function that automatically backs up at a user-specified time, supporting data recovery based on the backup point.

Provided Features

CacheStore(DBaaS) provides the following features.

• Auto Provisioning (Auto Provisioning): UI allows installation and configuration of Database (DB), and a redundant configuration is possible with a Sentinel-based Single Master server and Replica server (1 or 2).
• Operation Control Function: Provides a function to control the status of running servers. In addition to start and stop, restart is possible if there is an issue with the DB or to apply configuration values. When configured for high availability (HA), you can switch Active-Standby servers via Switch-over.
• Backup and Recovery: Provides a data backup function based on its own backup commands. The backup time window and storage agency can be set by the user, and additional fees are incurred depending on the backup volume. It also provides a recovery function for backed-up data, so when the user performs a recovery, a separate DB is created and the recovery proceeds to the point in time selected by the user.
• Parameter Management: Performance improvement and security-related DB configuration parameter modifications are possible.
• Service status query: Retrieves the final status of the current DB service.
• Monitoring: CPU, memory, DB performance monitoring information can be checked through the Cloud Monitoring service.

Components

CacheStore (DBaaS) provides pre‑validated engine versions and various server types according to the open‑source support policy. Users can select and use them based on the scale of the service they wish to configure.

Engine Version

The engine versions supported by CacheStore(DBaaS) are as follows.

Technical support can be used until the supplier’s EoTS (End of Technical Service) date, and the EOS date when new creation is stopped is set to six months before the EoTS date.

According to the supplier’s policy, the EOS and EoTS dates may change, so please refer to the supplier’s license management policy page for details.
