Free, opinionated, drop-in. https://zoph.me/posts/2023-01-08-subnet-watcher/ Sun, 08 Jan 2023 13:37:00 +0200 https://zoph.me/posts/2023-01-08-subnet-watcher/ <p>Are you tired of manually checking your AWS subnets to make sure they&rsquo;re not approaching the free remaining IP limit? Look no further than Subnet-Watcher, an open-source tool I&rsquo;ve developed at <a href="https://zoph.io">zoph.io</a>.</p> <p>Subnet-Watcher allows you to automatically check your subnets for a variety of metrics, such as whether they have the correct number of available IP addresses, or the number of detached ENIs. It also allows you to take action if any of these conditions are not met, such as sending an email notification and automatically recording a CloudWatch Metric.</p> https://zoph.me/posts/2020-02-02-cloudwatch-synthetics/ Sun, 02 Feb 2020 13:37:00 +0200 https://zoph.me/posts/2020-02-02-cloudwatch-synthetics/ <h2 id="canary-what">Canary What?</h2> <p><img alt="canary" loading="lazy" src="https://zoph.me/posts/resources/images/posts/2020-CW-Synthetics/canary.jpg"></p> <p>In software testing, a canary (also called a canary test) is a push of programming code changes to a small number of end-users who have not volunteered to test anything. The goal of a canary test is to make sure code changes are transparent and work in a real-world environment.</p> <p>Canary tests, which are often automated, are run after testing in a sandbox environment has been completed. Because the canary is only pushed to a small number of users, its impact is relatively small should the new code prove to be buggy and changes can be reversed quickly.</p>
