Service Overview

MariaDB(DBaaS) is an open-source relational database(RDBMS) with high compatibility with MySQL. Samsung Cloud Platform provides an environment that can automate MariaDB installation and perform management functions for operation through a web-based console.

MariaDB(DBaaS) is designed as a high‑availability architecture that performs storage‑based data replication and minimizes failover time. To prevent data loss, when the contents of the Active server change, they are synchronously replicated to the Standby server, and the read‑only server called Replica, used for read load balancing and disaster recovery (DR), is provided up to five instances. Additionally, it provides an automatic backup feature at user-specified times to prepare for issues with the DB server or data, enabling data recovery at the desired point in time.

Provided features

MariaDB (DBaaS) provides the following features.

• Auto Provisioning (Auto Provisioning): UI allows installation and configuration of Database (DB), and provides an Active-standby redundancy configuration built on storage replication. * When the active server fails, it automatically fails over to standby.
• Operation Control Management: Provides a function to control 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 high availability (HA) is configured, a switch-over allows the user to directly perform the Active-Standby node transition.
• Backup and Recovery: Provides data backup functionality based on its own backup commands. * The backup time window and storage provider can be configured by the user, and additional charges may be incurred based on the backup size. * It also provides a recovery function for backed‑up data, so when a user initiates a recovery, a separate database is created and the recovery proceeds to the point in time selected by the user (the backup creation time or a user‑specified time). * When restoring to a user-specified point in time, the restore point can be set up to 5 minutes, 10 minutes, 30 minutes, or 1 hour before the stored backup and archive files.
• Version Management: Provides Major and Minor version upgrade features based on certain functionality improvements and security patches.
• Replica configuration: For load balancing reads and disaster recovery (DR), up to five Read Replicas can be configured in the same or different regions.
• Audit setting: Provides an Audit setting feature that can monitor users’ DB access and the results of DDL (Data Definition Language)/DML (Data Manipulation Language) operations.
• Parameter management: It is possible to modify DB configuration parameters related to performance improvement and security.
• Service Status Lookup: Retrieve the final status of the current DB service.
• Monitoring: CPU, memory, performance monitoring information can be viewed through Cloud Monitoring and Servicewatch.
• DB User Management: View and manage the DB account (user) information registered in the DB.
• DB Access Control Management: Based on DB accounts registered in the DB, you can register and revoke allowed IPs for access.
• Archive Management: Within the DB server, you can set the Archive file retention period (1 day~35 days) and configure the Archive mode (On/Off).
• Export DB Log: You can export stored logs to the user’s Object Storage via Audit settings.
• Migration: Synchronizes data in real time with the operational database and supports migration using replication without service interruption.
• OS Kernel Upgrade: You can upgrade the OS Kernel to apply some feature improvements and security patches.
