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.

Elastic Load Balancing, auto scaling, and fault tolerant

Elastic Load Balancing (ELB) is a service from AWS to balance the load automatically. It helps to distribute incoming traffic and scale resources automatically to meet demands. Users enable it within a single or multiple availability zones to maintain application performance.

Features of ELB

ELB provides these features:

  • Highly available: In ELB, incoming traffic will be distributed automatically between multiple targets such as Amazon EC2 instances, IP addresses, and containers in a single or multiple Availability Zones.
  • Health checks: In ELB, it will detect unhealthy instances or targets. It will not send traffic to them. This traffic will be sent to healthy instances or targets.
  • Security Features: You can create security groups inVirtual Private Cloud(VPC) and manage them. These security groups are associated with ELB and provide additional networking and security. You can create non-internet-facing or internal load balancers.
  • TLS termination...
