Video description

This course will introduce you to serverless computing and then quickly dive into how to build serverless apps with Amazon Web Services (AWS).

Specifically, you will learn:

  • To build a REST API without worrying about servers, using AWS API Gateway
  • Set up your on-demand code via AWS Lambda
  • Execute Lambda code whenever incoming requests reach your defined REST endpoints
  • Store data in a database - naturally without managing any database servers!

We won't stop here though! Instead, you'll then dive even deeper into serverless computing and learn:

  • To add user authentication to your existing frontend apps and how you can then also protect your REST API against unauthenticated access with ease!
  • how you can easily integrate a complete user sign up & sign in flow (including user confirmation) into ANY app (web app, iOS or Android app!) with AWS Cognito
  • Deploy your web app in a serverless manner
  • Speed up the delivery of your static web app assets

Secure your serverless app

What else you can build with the services covered in this course and which other services might be interesting to you were to dive deeper regarding advanced development workflows.

What You Will Learn

  • Build, secure and run APIs without managing any servers using AWS API Gateway and Lambda
  • Host SPAs without managing any servers
  • Add user authentication to serverless applications
  • Run code on-demand in the cloud

Audience

Anyone who's interested in focusing on the core business logic instead of the infrastructure needed to run an API and/ or SPA. Anyone who wants to use modern techniques to create highly scalable and extremely cost-efficient web apps. Anyone who works with APIs and/ or SPAs on a regular basis and wants to learn how to create flexible and cost-effective web apps. Every developer who loves the "Dev" in "DevOps" but would be happy to make the "Ops" part easier.

Maximilian Schwarzmüller

Since the age of 13, he has never stopped learning new programming skills and languages. In his early days, he started creating websites simply for fun. This passion has remained and shaped his decision to work as a freelance web developer and consultant. Although he started web development on the backend (PHP with Laravel and NodeJS), he has progressed to becoming a front-end developer using modern frameworks such as React, Angular, and VueJS 2 in many projects.

The most rewarding experience for him is to see how people find new and better jobs, build exciting web applications, acquire amazing projects, or simply enjoy their hobby with the help of his content.
