Pricing Rules Platform ASG migration - tvlk-prod
As Ansible Tower will be decommissioned by the end of March 2020, we are migrating the prp
service from Tower based deployment to ASG.
When is this happening in tvlk-dev
?
This is already completed in tvlk-dev
and has been tested since December 2019.

When is this happening in tvlk-prod
?
ASG migration is planned to be completed on 3rd March, 2020 between 4 - 5AM SGT 3rd March between 9 - 10 AM SGT. We’ve chosen this time based on lowest traffic pattern in Datadog.
What changes are being made?
- New ALB and ASG will be created.
- Old NLB target group will include new ASG instances.
- Service name changes from
prp
to entprp
and CloudWatch log group path changes to /tvlk/app-java/entprp
- No changes made to endpoints in any environment, as a result there will be no configuration changes required by services calling
entprp
- Route 53 points to new ALB on 3rd March between 9 - 10 AM SGT.
What is the impact during this migration?
- During the migration period, we will apply Route 53 changes to point to the new ASG-based ALB.
- There is expected to be no impact during this process as the non-ASG instances are available in the new load balancers as well.
