Starting from March 20, 2023, Alibaba Cloud Service Mesh (ASM) will no longer provide maintenance or technical support for Istio resources that are deployed as add-ons in Alibaba Cloud Container Service for Kubernetes (ACK).
Note You can deploy Istio resources as add-ons in ACK by performing the following operations: log on to the ACK console, click the name of the cluster that you want to manage, and choose Applications > Service Mesh.

End-of-maintenance date

March 20, 2023

Impact

  • ASM no longer updates related features or provides technical support. You need to manually maintain the add-ons.
  • Istio resources deployed as add-ons are of earlier versions, and therefore may be incompatible with Kubernetes of later versions. For more information about version compatibility, see Supported Releases.

Solutions

We recommend that you release the Istio resources that are deployed as add-ons in ACK before March 20, 2023.

If you want to continue using the Istio resources, you can recreate the Istio resources in ASM. For more information about ASM, see ASM. For more information about the billing rules of ASM, see Billing rules.
Important Istio resources that are deployed as add-ons are of earlier versions, whereas ASM instances are of later Istio versions. Resource definitions vary based on the Istio versions. Take note of the resource definitions when you configure the resources in ASM. This ensures that your desired features are available.
