Course Roundup
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
