Great initiative @Vardhan the blog contains almost all kinds of question but this again is a very general question asked.
What is a Serverless application in AWS?
The AWS Serverless Application Repository enables you to quickly deploy code samples, components, and complete applications for common use cases such as web and mobile back-ends, event and data processing, logging, monitoring, IoT, and more. Each application is packaged with an AWS Serverless Application Model(SAM) template that defines the AWS resources used. Publicly shared applications also include a link to the application’s source code. There is no additional charge to use the Serverless Application Repository - you only pay for the AWS resources used in the applications you deploy. You can also use the Serverless Application Repository to publish your own applications and share them within your team, across your organization, or with the community at large. Again, the AWS Serverless Application Model (AWS SAM) extends AWS CloudFormation to provide a simplified way of defining the Amazon API Gateway APIs, AWS Lambda functions, and Amazon DynamoDB tables needed by your serverless application.
Hope this helps everyone!
