ElastiCache Memcached Cluster Upgrade

Scheduled Maintenance Report for Skeddly

Postmortem

The upgrade of our ElastiCache Memcached cluster was a success.

Skeddly was previously using a cache.m3.medium node type, which has now reached end-of-life.

We created a new cache.t3.medium cluster using CloudFormation, and migrated non-customer-facing components to use the new cluster.

Then, during our scheduled window, we migrated our API and web front-end to the new cluster. We chose to use a scheduled window because it affects customer sign-ins.

The old cluster will now be deleted by removing the old cluster from our CloudFormation templates.
