The second phase involves migrating the traffic over to the new systems in a manner that mitigates the risk of incidents while continually monitoring and confirming that we are meeting crucial metrics tracked at multiple levels. This approach has a handful of benefits.

On the Android team, while most of our time is spent working on the app, we are also responsible for maintaining this backend that our app communicates with, and its orchestration code. Image taken from a previously published blog post As you can see, our code was just a part (#2 in the diagram) of this monolithic service.

Global caches like the InnoDB buffer pool and MyISAM key cache and session-level caches like the sort buffer, join buffer, random read buffer, etc. Global memory caches are static in size as they are defined solely by the configuration of the database itself. Do these queries use more caches?

Most monitoring tools for migrations, development, and operations focus on collecting and aggregating the three pillars of observability— metrics, traces, and logs. Using a data-driven approach to size Azure resources, Dynatrace OneAgent captures host metrics out-of-the-box to assess CPU, memory, and network utilization on a VM host.

A couple of things worth noting: All of the sites in the leaderboard sites are pretty speedy, so this is NOT a name-and-shame exercise. Are you compressing and caching the right things? It shows how key metrics align with the rendering timeline (the filmstrip view at the top of the chart). Use code splitting judiciously.

Site performance is potentially the most important metric. Having a slow site might leave you on page 452 of search results, regardless of any other metric. With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. The code for the site is available on GitHub for reference.
