Use tags as the primary signal, expect <code>ListTagsForResource</code> to be your bottleneck, enforce tagging at provisioning time, and run an audit job that flags untagged resources so the policy stays honest.</p> <p>The &ldquo;delete a lot of AWS resources at once&rdquo; problem shows up in every account: CI sandboxes, expired test estates, dev environments forgotten about, ad-hoc reproductions left behind. Bulk cleanup tools that target this exist and work well. Used carelessly any of them is a footgun. Used carefully with tag filtering, they become one of the most useful pieces of cost discipline you can ship.</p>https://wintermutecore.com/services/Sun, 13 Feb 2022 11:11:11 -0100https://wintermutecore.com/services/<p><p style="text-align:center;"> <img src="https://wintermutecore.com/services.jpg" alt="Services" /> </p> </p> <p>Below is what we actually do day to day.

Most of the work falls into a few buckets: REST and gRPC APIs, distributed systems handling high request volumes, and the occasional batch job that has to be reliable more than fast.</p>
