Expert AWS Development

By: Atul Mistry

Overview of this book

Expert AWS Development begins with the installation of the AWS SDK and you will go on to get hands-on experience of creating an application using the AWS Management Console and the AWS Command Line Interface (CLI). Then, you will integrate applications with AWS services such as DynamoDB, Amazon Kinesis, AWS Lambda, Amazon SQS, and Amazon SWF. Following this, you will get well versed with CI/CD workflow and work with four major phases in the release process – Source, Build, Test, and Production. Then, you will learn to apply AWS Developer tools to your Continuous Integration (CI) and Continuous Deployment (CD) workflow. Later, you will learn about user authentication using Amazon Cognito, and also how you can evaluate the best architecture as per your infrastructure costs. You will learn about Amazon EC2 service and will deploy an app using it. You will also deploy a practical real-world example of a CI/CD application with the Serverless Application Framework, which is known as AWS Lambda. Finally, you will learn how to build, develop, and deploy the Application using AWS Developer tools such as AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy, and AWS CodePipeline, as per your project requirements.

Serverless architecture with Lambda

AWS Lambda is a compute service. It is called a  serverless architecture because you will not provision or manage any servers. Your code will execute whenever you need it. It will scale automatically to 1,000 requests per second.

You will pay for the compute time that you consume to run the code; there is no extra charge when the code is idle. You can virtually run the code for any type of application and backend service, with zero administration.

AWS Lambda provides high-availability compute infrastructure to perform the administration of resources. This includes operating systems and server maintenance, automatic scaling, capacity provisioning, code monitoring, and logging.

You need to write your code in an AWS Lambda supported language; currently AWS Lambda supports Java, Node.js, C#, Go, and Python.

AWS Lambda is also known as event-driven architecture. It will execute the code in response to any events, such as if file is uploaded or downloaded into an...
