Well, this has been a really insightful chapter indeed. Before we move on to the next chapter, here's a quick look at the things we have learned so far!

First up, we started with a quick look at the various messaging services that are provided by AWS. Next, we deep dived into the amazing world of Amazon SNS, created our very first topic, and subscribed to both email and phone subscriptions. We also looked at how to configure and leverage SNS' text messaging service.

Once we had the basics of SNS covered, we moved on to the next messaging service, SQS, and learned a bit about its concepts and terminologies as well. We created our first queues using both the AWS Management Console and the AWS CLI, and finally we looked at a really useful integration of the two services that you can use to design and build scalable and decoupled cloud applications. We finally topped it all off with a handy next steps guide that you ought to try out in your free time!

In the next chapter, we will be learning and exploring two really awesome analytics services, in the form of Amazon Elastic MapReduce and Amazon Redshift, so stay tuned!
