In the world of modern development, serverless computing has become table stakes. Serverless computing has seen a major uptake with AWS Lambda having an increased adoption of 667% in 2018. Companies are making the switch to serverless for shorter time to market and decreased operational costs, but for you the advantage lies in the ability to offload the burden of managing infrastructure to serverless platforms, so you can focus on building even better apps.

In this course, you will learn how to run serverless applications using AWS Lambda. You’ll start with the basics such as creating a web service where you’ll learn the steps to deploy an AWS Serverless Application Model (SAM). You’ll then move on to more advanced topics such as handling HTTP Requests, using external storage, and managing sessions and user workflows. By the end of this course, you will be ready to work with AWS Lambda in a professional setting, and you’ll have a great, transferable skill that employers will love to see.

Running Serverless Applications with AWS Lambda

If an application server approves or rejects client requests, talks to back-end storage, schedules asynchronous processing, and passes back results to client devices, it is an example of a three-tier server setup. 

If an application server approves or rejects client requests, talks to back-end storage, schedules asynchronous processing, and passes back results to client devices, it is an example of a three-tier server setup.

Each user can get their own specific privileges and sign in to the client application with an IAM username and password, and the client application can directly use AWS SDK to access storage, databases, or queues. 

It stores usernames and passwords securely, optionally allowing users to sign up themselves or even sign in through federated authentication systems.

It allows you to safely pass on temporary access rights with the account credentials to client devices. It does not require the creation of any kind of user records or up-front registration.

It allows users to read or write only certain fields of a DynamoDB record matching their ID.

Lambda functions work under temporary credentials that are only valid for a short period. Unfortunately, there is no way to generate signed URLs that last longer.
