Amazon Web Services (AWS) is by far the largest Cloud provider today. It provides many service offerings which simplify the deployment and maintenance of applications. In this chapter, you’ll learn how to use a few of these to deploy a Vapor app.
Your first step is to start an EC2 instance. EC2 is an AWS Virtual Machine product. This gives you a plain Linux machine you can use to run your Vapor application.

Install Swift
To build your Vapor app, you must install Swift on your EC2 instance. Swift supports a number of Linux platforms, including Ubuntu and CentOS. Visit https://swift.org/getting-started/ for details on installing for your platform.

System Memory
The Swift compiler can use a lot of memory. Small cloud instances, such as a t2.micro, don’t contain enough memory for the Swift compiler to work. You can solve this problem by enabling swap space. In Terminal, enter the following:

Setting up your application
To set up your application, you will first clone it from GitHub. To build the TILapp example from the rest of the book, enter the following commands:
# 1
git clone https://github.com/raywenderlich/vapor-til.git
# 2
cd vapor-til
# 3
swift build -c release --enable-test-discovery

Setting up a PostgreSQL server
For your database, you will use Amazon Relational Database Service (RDS). This AWS database service supports several popular relational database systems, including PostgreSQL.

Installing and configuring nginx
nginx is a popular web server, typically used as a proxy server in front of other web apps. For Vapor apps, this is useful because it provides additional features such as compression, caching, HTTP/2 support, TLS (HTTPS) and more.

Running your app as a system service
You want your app to run when your instance boots and to restart if it crashes due to a critical error. The easiest way to accomplish this is to integrate it as a system service. Most versions of Linux that Swift — and, therefore, Vapor — support use a service called systemd to accomplish this.

Where to go from here?
You now have the basics of how to set up a Vapor app on AWS. There are many more things AWS allows, such as scaling, IP pooling, automatic backups, replication and so on. You can add load balancers and custom DNS names with TLS certificates. There are also other deployment options, such as running in Docker or even using AWS Lambda. Covering all of AWS would be a whole book in itself! Spend some time with the AWS documentation and tutorials to learn more.
