We’re happy to announce that we’ve added a new feature which will make it easier for you to copy your trigger setup from one app to a new one. Anomaly detection triggers are a great way to get notified about unwanted events in your app. These anomalies are things like a high error rate, a lack of free disk space, or a high CPU usage. If your apps have a lot of the same requirements and infrastructure, you may have a lot of the same triggers across your apps.

In our series on how to deploy an app to AWS with the least effort, we've talked about getting started, preventive measures, and securing your app. Today, we're going to focus on DNS (domain name system), specifically the AWS DNS service Route 53. As you're deploying your web app, you will inevitably use DNS.
