Automating Application Code Deployment to Amazon EC2 Instance

Correct Answer: B.

AWS Code Deploy can be used to automate deployment to Amazon EC2 instances and on-premise servers.

Option A is incorrect as AWS Elastic Beanstalk is an application management platform that can be used for managing application deployment handling capacity provisioning, load-balancing, auto-scaling & application health monitoring.

Option C is incorrect as AWS Config can be used to audit, evaluate configurations of AWS resources.

It is not used to automate code deployment to Amazon EC2 instance.

Option D is incorrect as AWS CloudFormation is used for infrastructure deployment & automating resource creation within AWS Cloud Infrastructure.

The correct answer is B. AWS CodeDeploy.

AWS CodeDeploy is a fully managed deployment service that automates application deployments to Amazon EC2 instances, on-premises instances, and serverless Lambda functions. It simplifies the process of deploying and updating applications, making it faster and more reliable.

With AWS CodeDeploy, you can deploy your code to any number of instances, all at once or in batches, and track the status of each deployment. It supports various deployment strategies, including rolling deployments, blue/green deployments, and canary deployments.

AWS Elastic Beanstalk, on the other hand, is a fully managed service that makes it easy to deploy and scale web applications and services. It includes a variety of preconfigured platforms and environments for popular programming languages and frameworks. Elastic Beanstalk automatically handles capacity provisioning, load balancing, and scaling of the application.

AWS Config is a service that provides a detailed inventory of resources and their configurations, as well as configuration change history. It enables you to track compliance with various policies and best practices, and set up automatic remediation actions.

AWS CloudFormation is a service that allows you to create and manage AWS resources using code. It uses templates to define the infrastructure and configuration of your resources, and automates the provisioning and updating of those resources.

While AWS Elastic Beanstalk, AWS Config, and AWS CloudFormation can all be used to manage and deploy applications on AWS, they are not specifically designed for code deployment automation. In contrast, AWS CodeDeploy is focused specifically on application deployment automation, making it the best choice for this use case.
