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.

Microservices architecture

A microservice is a method used to develop a scalable software system that will support any kind of device. It is an easily and independently deployable modular service that will run a unique process, and communicates through a lightweight mechanism to fulfill business requirements.

To understand microservices architecture, you need to understand what a monolithic architecture style is and why we need microservices. In a monolithic architecture, an application is created with tightly coupled modules as single units and is deployed on the web or an application. If you want to modify or scale the application, then you need to build and deploy an entire application or scale the whole application, instead of specific components. In this case, microservices can help you.

The following diagram shows the difference between monolithic and microservices architecture:
