Summary

For now, we have done all we need to do to deploy a robust and secure application on AWS with locked-down traffic and HTTPS enforced. We have covered a lot to get here, and the skillset that you have gained in this chapter can be applied to pretty much any other project you want to deploy on AWS if you can package it in Docker. You now understand the advantages of HTTPS and the steps needed to not only achieve the HTTPS protocol but also to map your URL to the IP address of a server or a load balancer. What is more, we automated the attachment of certificates that we created using Certificate Manager to our load balancer in Terraform using the powerful data query resource that Terraform has to offer. Finally, this all came together when we managed to access our application using HTTPS and only HTTPS. Not only have we developed some practical skills that will become useful in many future projects, but we have also explored the nature of how HTTPS and DNS work, giving us a deeper...
