AWS Lightsail is a set of services offered by AWS which can be used to run the infrastructure needed for hosting web applications: virtual servers, managed databases and load balancers. They are similar to the standard offerings from AWS but have a smaller feature set.
Through the AWS CLI setting up the infrastructure and automating it can be automated.
To launch an environment for hosting web applications the launch-environment.sh script can be used. It creates a managed MySQL database, a load balancer and two web servers. The web servers are attached to the load balancer and run a simple nginx as the web server in a Docker container.
