Microsoft Azure Service Fabric 9.0 Third Refresh Update Release

Azure Service Fabric 9.0 Third Refresh is now available!

We are excited to announce that 9.0 Third Refresh release of the Service Fabric runtime has started rolling out to the various Azure regions along with tooling and SDK updates. The updates for .NET SDK, Java SDK and Service Fabric runtimes can be downloaded from the links provided in Release Notes. The SDK, NuGet packages and Maven repositories will be available in all regions within 7-10 days.

Key Announcements

• Azure Service Fabric will block deployments that do not meet Silver or Gold durability requirements starting on 9/30/2022. 5 VMs or more will be enforced with this change to help avoid data loss from VM-level infrastructure requests for production workloads. Enforcement for existing clusters will be rolled out in the coming months.
  For details see: Durability characteristics of the cluster.
• Azure Service Fabric node types with VMSS durability of Silver or Gold should always have Windows update explicitly disabled to avoid unintended OS restarts due to the Windows updates, which can impact the production workloads. This can be done by setting the "enableAutomaticUpdates": false, in the VMSS OSProfile. Consider enabling Automatic VMSS Image upgrades instead. The deployments will start failing from 09/30/2022 for new clusters, if the WindowsUpdates are not disabled on the VMSS. Enforcement for existing clusters will be rolled out in the coming months.

Breaking Changes

Customers running Azure Service Fabric Linux Clusters will not be able to scale out or reimage (manual or auto via VMSS OS Image Update) nodes or create new Linux clusters without first upgrading to Service Fabric version 9.0.1086.1. Also, if your application requires JDK, then you will need to install a JDK of your choice since SF will not install the JDK as part of the SF installation. Starting 8/19/2022, the following versions have been deprecated and will not be available on Linux for new cluster creation or node reimage/scale out operations:

• 9.0 CU2/CU1/RTO
• 8.2 CU4/CU3/CU2.1/CU2/CU1/RTO

Details: Service Fabric Runtime (for Linux) placed a dependency on Zulu for Azure build of OpenJDK which is no longer supported as announced in their dev blog. Since the creation of new Linux clusters or scale-out/reimage of nodes required all the dependencies to be installed, these workflows broke when the dependency became unavailable.
Beginning with 9.0 CU 2.1 release, Service Fabric Runtime will no longer install any JDK dependency which will ensure that customer can scale out, reimage, or create new Linux clusters. If your application needs JDK, please utilize an alternate mechanism to provision a JDK. To get the latest Service Fabric Runtime releases with this change, follow the upgrade documentation. If you depend on a JDK, please be sure to install one of your choice.
