&gt; You never know what you don&#x27;t measure and test<p>Funny you should mention that. :) I work at Google on PerfKit Benchmarker (<a href="https:&#x2F;&#x2F;github.com&#x2F;GoogleCloudPlatform&#x2F;PerfKitBenchmarker" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;GoogleCloudPlatform&#x2F;PerfKitBenchmarker</a>). Not only can you measure and test GCP (and other clouds), but we&#x27;re trying to make it very easy for you to do so!<p>(PKB doesn&#x27;t have a benchmark for App Engine yet, though. Sorry.)
