Your company develops a variety of web applications using many platforms and programming languages with different application dependencies. Each application must be developed and deployed quickly and be highly available to satisfy your business requirements. Which of the following methods should you use to deploy these applications rapidly?

Answer options:

A.Deploy web applications from Docker containers in an Elastic Beanstalk environment with Auto Scaling and Elastic Load Balancing.
B.Use the AWS CloudFormation Docker import service to build and deploy the applications with high availability in multiple Availability Zones.
C.Develop each application’s code in DynamoDB, and then use hooks to deploy it to Elastic Beanstalk environments with Auto Scaling and Elastic Load Balancing.
D.Store each application’s code in a Git repository, develop custom package repository managers for each application’s dependencies, and deploy to AWS OpsWorks in multiple Availability Zones.

Answer – A
Elastic Beanstalk supports the deployment of web applications from Docker containers. With Docker containers, you can define your own runtime environment. You can choose your own platform, programming language, and application dependencies (such as package managers or tools) that aren`t supported by other platforms. Docker containers are self-contained and include all the configuration information and software your web application requires to run.
Using Docker with Elastic Beanstalk, you have an infrastructure that automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring.
