Since Lambda added SQS as an event source, there has been a misconception that SQS is now a “push-based” service. This seems true from the perspective of your function because you no longer have to poll SQS yourself. However, SQS itself hasn’t changed – it is still very much a “poll-based” service. The difference is that the Lambda service is managing the pollers (and paying for them!) on your behalf.

In our last post, we covered CloudWatch Metrics in a great deal of detail. We looked at how we can use it to monitor the health of our Lambda functions, including setting up service dashboards as well as alerts. In this post, we will focus on its sister service – CloudWatch Logs. We’ll see how it works and how to get the most out of it.

Many articles have been written about AWS Step Functions since it was first introduced in 2016. Most of them create the impression that the service is simply an extension of the Lambda function that allows us to stitch together multiple Lambda functions to call each other. But actually, it is much more than that. Step Functions allows us to design and build the flow of execution of modules in our application in a simplified manner.
