Web performance is a broad subject, and you’ll find no shortage of performance testing tips and tutorials all over the web. Before you begin tuning your website or application, you must first figure out which metrics matter most to your users and establish some achievable benchmarks. What is Performance Testing?

These have inspired me to summarize another performance activity: evaluating benchmark accuracy. If the benchmark reported 20k ops/sec, you should ask: why not 40k ops/sec?

This means that there is no need to provision or manage servers (or even containers). If you haven’t done so already, providing a testing environment for developers to easily test their functions with AWS solves most of these challenges and makes the required tooling similar to what’s required for operating microservices.
