Interestingly, our partner RedHat reported in 2021 that around 80% of deployed workloads are databases or data caches, storing data in persistent volume claims (PVCs). For example, let’s say you have an idea for a new social network and decide to use Kubernetes as your container management platform.

However, that pesky 20% on the back end can have a big impact on downstream metrics like First Contentful Paint (FCP), Largest Contentful Paint (LCP), and any other 'loading' metric you can think of. Caching the base page/HTML is common, and it should have a positive impact on backend times. But what happens when it doesn't?
