It so happened that until 2020, I did not deal with clouds. When I finally delved into this topic, I got a little lost from the abundance of services offered in AWS.
It was necessary to create an application with the following features:
- Login via facebook or google.
- The ability to download and display media files.
- Receiving events from the server in real time.
This article describes the services that I needed to implement the project and feel the process.

When I started out, I didn't think I might like it. I resisted. So, for example, I coded the jwt-authentication mechanism myself, instead of using Cognito.
But I changed my mind. Still, it's nice to shrug off the burden of infrastructure code and focus on business logic. After getting a little more comfortable, I began to experience the feelings of a child in an amusement park. Each new service brings new fun. I am glad that this park has not yet been fully explored. For myself, I made a decision that I am here for a long time.
