Serverless Web Application on AWS [S3, Lambda, SQS, DynamoDB and API Gateway]

In this AWS video tutorial, we will show you how to create a serverless web application using AWS services like Lambda, API Gateway, SQS, DynamoDB, and S3.

We'll start by creating a static website on S3, which will contain a form for submitting order information. When the form is submitted, the data will be passed to the API Gateway service, which will trigger a Lambda function to process the information.

The Lambda function will then add the order information to an SQS queue for further processing. Another Lambda function will pick up the message from the queue and add the order information to a DynamoDB table for storage.

Throughout the tutorial, we'll discuss the benefits of serverless computing and how AWS services can help you build scalable and cost-effective applications without the need for servers.

By the end of this video, you'll have a better understanding of how to use AWS services to create a serverless web application that can process orders submitted through a form. So, let's get started!

TIP: Learn to use chatgtp by inputing the error your recieving. That is how i breeze thru issues when the arise. Example the Rollback Error: To fix the issue with your AWS CloudFormation template, especially regarding the error that occurred because the Lambda function runtime nodejs12.x is no longer supported, you need to update the Runtime property of your ItemLambdaFunction resource to a supported version

I may have found the issue, it is within the lambda function as the "aws-sdk" is missing

Sir could you please help me with one thing. I followed the exact same instructions. Bit in the template i had to change the node version from 12x to 18x as aws said it was outdated, then it worked. But at the end when i launch the site using the s3 link, the frontend loads, but says failed to display the values, and also it doesn't accept any value that we enter and displays an error
