1 - Overview

Service Overview

Scalable DB(DBaaS) is a database service designed to efficiently manage rapidly increasing data processing demands and user load.
Scalable DB (DBaaS) automatically scales resources up or down in response to traffic changes, maintaining optimal performance and availability. This maximizes resource efficiency and provides cost savings. Additionally, the Proxy Endpoint configuration feature not only distributes database load by separating read/write and read‑only roles, but also enables more efficient independent connection management per application. By combining these features, users can reduce the complexity of service operations and build a cost‑effective, scalable database environment.

Service Diagram

Provided features

Scalable DB(DBaaS) provides the following features.

• Auto Provisioning: Allows installation and configuration of the Database (DB) via UI, and provides an Active‑standby redundancy configuration built on storage replication. In case of an Active server failure, it automatically fails over to the Standby.
• Operation Control Management: Provides functionality to control the status of running servers. Offers start and stop functions for the entire cluster and restart buttons for each node, supporting a flexible cluster and node management environment for users.
• Scaling feature: Through the automatic scaling feature, read nodes are automatically expanded and contracted according to the policy set by the user. Additionally, users can manually adjust the number of nodes as needed.
• Proxy Endpoint configuration: By using the Proxy Endpoint feature that separates read/write and read‑only connections, it supports database connection optimization and traffic distribution.
• Backup: Provides data backup functionality based on its own backup command. Users can set the backup time window and storage repository, and additional fees are incurred based on backup size.
• Read Node status view: Provides real-time Read Node status view functionality, allowing monitoring of replication lag time (Replication Lag Time) to accurately determine data synchronization status.
• Service Status Query: Retrieves the final status of the current DB service.
• Monitoring: CPU, memory, performance monitoring information can be viewed through Servicewatch.
