Overview

Service Overview

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

CacheStore(DBaaS) provides a Sentinel architecture composed 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 if a failure occurs on the Master server, it automatically fails over the Replica servers to the Master server. Additionally, to prepare for potential issues with the DB server or data, we provide a feature that automatically backs up at a user-specified time, allowing data recovery based on the backup point.

Provided features

CacheStore (DBaaS) provides the following features.

• Auto Provisioning: UI allows installation and configuration of Database (DB), and a redundant configuration with a Sentinel-based Single Master server and Replica servers (1 or 2) is possible.
• Operation Control Feature: Provides a function that controls the status of running servers. * In addition to start and stop, a restart is possible if there is a DB issue or to apply configuration changes. * When configured for high availability (HA), you can switch the Active-Standby servers using a switch‑over.
• Backup and Recovery: Provides data backup functionality based on its own backup commands. * The backup time window and storage location can be set by the user, and additional charges are incurred based on the backup size. * It also provides a recovery function for backed‑up data, so when the user initiates a recovery, a separate database 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, performance monitoring information can be viewed through Cloud Monitoring and Servicewatch.
• Minor version upgrade: Minor version upgrades can be performed within the same Major version to apply some feature improvements and security patches.
