Delving into AWS deployment architectures

When deploying applications on AWS, there are numerous ways of deploying the app. One can make use of the services that AWS provides to build an architecture that can maximize performance and reduce costs. We will explore two topologies that can be used to deploy our AngularJS apps in the following sections.

The EC2 server-based architecture
