Maintenance & Upgrades¶

Servala keeps your service instances up to date and healthy as part of the managed service. This page describes how maintenance and version upgrades work in general. Service-specific behavior is documented on the relevant page in the Service Catalog.

What maintenance covers¶

• Security patches: applied to keep instances secure.
• Minor version updates: minor and patch-level software updates are applied automatically as part of the service.
• Infrastructure maintenance: updates to the underlying platform and worker clusters.

Version upgrades¶

Major version upgrades (for example moving a database to a new major release) are treated separately from routine patching:

• They are coordinated and typically require an explicit action or confirmation.
• They can introduce behavior changes, so review the upstream release notes for the service before upgrading.
• Availability and the exact upgrade path depend on the service and offering.

Maintenance windows¶

Maintenance that may cause a short interruption is performed within a maintenance window to limit the impact on your workloads.

High availability¶

Instances provisioned with a high-availability offering reduce the impact of maintenance, as updates can be rolled out without full downtime. Availability depends on the chosen offering and compute plan. See Compute Plans & SLAs.
