Overview

Service Overview

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

CacheStore (DBaaS) provides a Sentinel architecture consisting of a master server that handles read and write operations and read-only replica servers that replicate the master data. Sentinel checks the status of the database server where the engine is installed. If a failure occurs on the master server, it automatically fails over the replica servers to the master server. Additionally, to prepare for issues with the DB server or data, it provides an automatic backup feature at user-specified times, enabling data recovery based on the backup point in time.

Features

CacheStore (DBaaS) provides the following features.

• Auto Provisioning: You can install and configure the database (DB) through the UI, and configure a high-availability setup with a Sentinel-based single master server and one or two replica servers.
• Operational Control Feature: Provides functionality to control the status of running servers. * In addition to start and stop, you can restart the service to address database issues or apply configuration changes. * When configured for high availability (HA), you can switch between the active and standby servers using a failover.
• Backup and Recovery: Provides a data backup feature based on a proprietary backup command. * Users can configure the backup time zone and retention period, and additional fees apply based on the backup capacity. * It also provides a data restoration feature for backed-up data. When a user initiates a restore, a separate database is created, and the restoration process proceeds to the point in time selected by the user.
• Parameter management: You can modify DB configuration parameters related to performance improvements and security.
• Service Status Check: Retrieves the final status of the current DB service.
• Monitoring: You can view CPU, memory, and performance monitoring information through Cloud Monitoring and Servicewatch.
• Minor version upgrade: You can upgrade to a minor version within the same major version to apply certain feature improvements and security patches.
