R19 - Double lane

Service affecting R19 template that improve NFS performance.

Process
We upgrade in two steps to use the new R19 release of the cloud template. Of these two steps, the intermediate step is non-service affecting, and the final step is service affecting.

Overview
This version contains performance improvements for NFS.

Updates

• Ubuntu version update including latest security patches.
• This upgrade is service-affecting, as all instances have to be recreated.

Update Steps

• Use the intermediate template (non-service affecting) (duration: 10 minutes)
  • This step will upgrade the backup machines hosted in the second Availability Zone in your Cloudslot.
  • The network drive containing the Artemis queue store and your Elastic IPs will remain.
• Use the final template (service affecting) (duration: 10 minutes)
  • This step will upgrade the primary machines in the first Availability Zone in your Cloudslot.
  • The runtimes on the machines will be restored using the active release in the eMagiz portal.
• User actions after applying the final template:
  • Check if all runtimes are reachable by Deploy Architecture.
  • Check if all flows have been installed according to the active release.
  • Check if messages pass through the model by verifying a critical message flow in external systems.
