Grasp how aws lambda works and its fundamental concepts
Create a real world API using aws lambda functions and Amazon API Gateway.
Avoid common pitfalls and mistakes.
Understand the security concept around AWS services.
Understand and use triggers for lambda aws functions.
Learn how to call lambda functions directly from java code.

Building a Serverless AWS lambda API on AWS in java is a great way to get started to develop applications on the AWS lambda platform that scale without the hassle of managing servers.

This course is intended for every Java developer that wants to be able to build a productive serverless API within a few hours, using aws lambda and Amazon API Gateway.

The Amazon aws cloud platform offers a lot of amazing services.

However, each one of those services has a learning curve, and it can cost a lot of time become productive with any of these services just by reading the developer guides and taking the Trial and Error approach.

In this course you’ll learn how to write and deploy a aws lambda functions and how to create an AWS API Gateway endpoint to use that AWS lambda function.

At the end of the course you’ll learn to create a production ready webservice on the Amazon Web Services platform that can be used to resize any image on the fly.

We discuss all of the aws-lambda configuration options, how to configure the IAM (AWS Identity and access Management) to give your aws lambda function access to Amazon Web Services such as AWS s3, AWS Cloudwatch, ... and we'll configure AWS API Gateway to create a REST api endpoint for our serverless aws lambda function.
