Create a chat web app using Amazon Web Services - Lambda, DynamoDB, API Gateway, S3, Cognito, CloudFront, and moreAbout This VideoS3 (Simple Storage Service) - For storing static HTML and vending it to your users' browsersLambda - For executing logic in the cloud for storing and retrieving data in your applicationIAM (Identity and Access Management) - For securing access to your servicesAPI Gateway - For presenting a well-modeled API to your clients and automatically generating client-side code to communicate with itDynamoDB - For quickly storing and retrieving data at scaleCognito - For managing users, account creation, and logins securelyCloudFront - For accelerating the delivery of your site to end users with a CDNIn DetailImmerse yourself in Amazon Web Services (AWS) with this hands-on, project-based course - and truly internalize some highly valuable skills in the world of technology. We'll walk you through building your own chat website using nothing but AWS services - and no standalone services or server instances at all! Building a "serverless app" using AWS and its Lambda service is a great introduction to the core services AWS offers. We'll tie it all together by learning and practicing Javascript, and we'll learn about CORS to grant browsers the permissions they need to run a serverless application. Even if you're familiar with AWS, you'll learn valuable techniques on how to build a fully functional, dynamic website without maintaining any servers at all - not even via EC2! Your highly experienced guides through this project are Frank Kane, formerly a senior manager at Amazon, and Brian Tajuddin, a principal engineer also formerly working at Amazon. You'll be learning AWS from people who were there when it was being created. You'll join over 140,000 other students of the Sundog Education team who have leveled up their careers with hot technical skills. Show and hide more
