Design applications to handle potential downtime gracefully.
Consider non-managed, multi-region deployments to enhance availability.
One of the significant drawbacks of cloud-based managed databases is the lack of control over maintenance schedules, reboots, and performance issues caused by noisy neighbors, i.e., other tenants on the same infrastructure. Cloud providers might schedule maintenance or reboot instances at inconvenient times for users, resulting in potential downtime and disruptions. These maintenance windows, upgrades, and reboots may not be helpful to the organization. Typically, these maintenance australia whatsapp number data windows are non-negotiable. Conversely, non-managed solutions usually do not require such maintenance windows, and organizations can schedule any needed maintenance according to their schedule.
Consider a non-managed solution where maintenance does not involve any interruptions to applications.
Implement monitoring and alerting to prepare for and mitigate disruptions.
Evaluate the provider’s track record for maintenance scheduling and impacts.
Reboot Requirements for Configuration Changes
Modifying database options often requires rebooting the database instance, which can be highly inconvenient, particularly in production environments where uptime is critical. Rebooting can take significant time, resulting in service interruptions and potential data unavailability.
Plan configuration changes during low-traffic periods.
Test configuration changes in a staging environment before applying them in production.
Consider using services that offer dynamic configuration changes without reboots.
Limited Multi-Region Support
Managed MySQL services typically offer very limited, if any, multi-region support, putting applications at risk in the event of a regional failure. For the few services that do provide multi-region support, the topology options are often restricted to a simple read replica in another region. Disaster recovery options are cumbersome, and more complex deployments like Active/Active MySQL are not possible.
