Maintenance overview

KakaoCloud Maintenance service is an integrated maintenance solution designed to ensure stable cloud service operations.
Maintenance enables safe execution of instance upgrades and configuration changes through a cloud-based maintenance system. It helps plan stable service operations by identifying tasks with potential downtime in advance and scheduling them at the desired time.

While KakaoCloud Maintenance supports safe execution of cloud service updates, actual updates are carried out according to each service's policy. Service impact may occur during updates, so it is recommended to perform backups in advance.
In addition, through KakaoCloud Alert Center, you can configure event notification policies for each service. When thresholds are reached, alert messages are sent immediately to responsible parties for more efficient resource management. For configurable events, refer to Cloud Trail > Key concepts, and for setting notification policies, see Alert Center > Create and manage notification policies.

Terminology
  • Task: A maintenance unit that includes required version information and recommended/deadline schedules, managing multiple resources together.
  • Resource: An individual unit within a task, representing the smallest management unit for which an execution schedule can be set.

Purpose and use cases​

Maintenance helps safely perform OS, engine, and kernel upgrades and configuration changes for MySQL and other instances in a cloud environment. Without this service, unexpected downtime or difficulty in scheduling updates may directly impact services, making stable operation difficult. Unplanned service outages and operational risks may increase management burden.

Users can schedule tasks during low-traffic hours, anticipate potential downtime, and maintain stable service operation. Automating maintenance tasks such as security patches, performance improvements, and configuration changes enables failure prevention and rapid response, thereby improving operational efficiency.

Features​
