1 - Overview

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 architecture consisting of a Master server that performs read/write operations and read‑only Replica servers that replicate the Master data. Sentinel checks the status of DB servers where the engine is installed and automatically fails over the Replica servers to become the Master server if a failure occurs on the Master server. Additionally, it provides an automatic backup feature at user‑specified times to prepare for issues with the DB server or data, allowing data recovery based on the backup point.

Provided Features

CacheStore(DBaaS) provides the following features.

• Auto Provisioning: It is possible to install and configure the Database (DB) via UI, and a redundant configuration with a Sentinel-based Single Master server and Replica server(s) (1 or 2) is possible.
• 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 based on backup size. It also provides a recovery function for backed-up data; 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: It is possible to modify DB configuration parameters related to performance improvement and security.
• 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.
• Minor version upgrade: Minor version upgrades can be performed within the same Major version to apply some feature improvements and security patches.

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 according to the scale of the service they want to configure.
