One of Checkly's strengths is the capability to monitor key transactions on your site. It'd be missed opportunity if we didn't reuse it to monitor our own product! But for some important flows that comes with a couple of pitfalls. In this post, we'll take a closer look at how we monitor one of our top key flows: signup.
The Simple Notification Service, or SNS for short, is one of the central services to build serverless architectures in the AWS cloud. SNS itself is a serverless messaging service that can distribute massive numbers of messages to different recipients. These include mobile end-user devices, like smartphones and tablets, but also other services inside the AWS ecosystem. SNS’ ability to target AWS services makes it the perfect companion for AWS Lambda.

In December, information security researchers discovered a serious vulnerability in the popular open-source logging library, Log4j. If exploited, this vulnerability, known as Log4Shell, could allow malicious attackers to execute code remotely on any targeted computer. Millions of computers use Log4j. According to one study, 93% of all cloud environments are affected by the vulnerability.
