About Building a Serverless AWS lambda API on AWS in java

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.
