Azure APIM Upgrades

Question

Dear Team,

How does APIM Upgrades cycle look like?

I noticed that my Developers Tiers instances automatically upgraded with downtime and no notice (only health event alert), which is fine since there is no SLA there - but should I expect the same for my Premium deployment?

If not, do I need to execute upgrades by myself, how often to expect to carry out such operation?

Many thanks,
Federico

@FedericoZarelli-6386 ,

Thanks for reaching out. The upgrade cycle for Azure API Management (APIM) instances varies based on the service tier. For the Developer tier, updates are applied automatically, and there is no SLA, which means instances can experience downtime during upgrades without prior notice.

For the Premium tier, while updates are also applied automatically, it is important to note that upgrades normally do not affect the availability of your apps. The upgrade process adds extra instances to ensure that the same capacity is available during the upgrade, and the full upgrade process typically finishes not more than a day. However, you will not have control over when these updates are applied, and they will occur automatically.

You can monitor service updates and receive notifications about them through the Azure portal, and it is advisable to validate updates in non-critical instances before they are applied to production instances.
