Uploading Different Versions of an Application

Answer - C.

The AWS Documentation mentions the following.

Elastic Beanstalk creates an application version whenever you upload source code.

This usually occurs when you create an environment or upload and deploy code using the environment management console or EB CLI.

Elastic Beanstalk deletes these application versions according to its life cycle policy and when you delete the application.

You can also upload a source bundle without deploying it from the application management console or with the EB CLI command eb appversion.

Elastic Beanstalk stores source bundles in Amazon Simple Storage Service (Amazon S3) and doesn't automatically delete them.

Options A and B are incorrect since this would be the least efficient way to maintain application revisions.

Option D is incorrect since you would not use CodePipeline for application versions.

Elastic Beanstalk is a fully managed service provided by AWS that helps developers deploy and run their applications at scale. It takes care of the underlying infrastructure, including the application server, database, and other resources needed to run the application. Elastic Beanstalk provides an easy-to-use interface for deploying and managing applications.

If your team is looking to upload different versions of an application using Elastic Beanstalk, there are different approaches you can take, such as creating multiple applications, creating multiple environments, uploading the application's source code or source bundle, or using CodePipeline to streamline the various application versions.

Here's a detailed explanation of each of these approaches:

A. Create multiple applications in Elastic Beanstalk: Creating multiple applications in Elastic Beanstalk is one way to manage different versions of an application. Each application would have its own resources, such as a web server, database, and other dependencies, and would be deployed independently. This approach provides greater isolation between different versions of the application but may result in higher costs and greater management overhead.

B. Create multiple environments in Elastic Beanstalk: Creating multiple environments in Elastic Beanstalk is another way to manage different versions of an application. An environment is a collection of AWS resources, such as EC2 instances and databases, that are used to deploy and run an application version. Each environment can have its own configuration settings, such as instance types, security groups, and database settings. This approach allows you to deploy different versions of the application to different environments and provides a high degree of flexibility and control over the deployment process.

C. Upload the application's source code or source bundle in the Elastic Beanstalk console: Uploading the application's source code or source bundle in the Elastic Beanstalk console is the most straightforward approach to deploying a new version of an application. Once the application's source code or source bundle has been uploaded, Elastic Beanstalk automatically creates the necessary resources, such as EC2 instances, load balancers, and databases, to run the application. This approach is ideal for smaller teams or applications that do not require complex deployment workflows.

D. Use CodePipeline to streamline the various application versions: Using CodePipeline is a more advanced approach to managing different versions of an application. CodePipeline is a fully managed continuous integration and continuous delivery (CI/CD) service that automates the entire software release process. It provides a graphical interface for defining the various stages of the deployment pipeline, including building, testing, and deploying the application. This approach is ideal for larger teams or applications that require a more complex deployment workflow.

In conclusion, there are different approaches you can take to manage different versions of an application using Elastic Beanstalk, depending on your team's requirements and level of expertise. Creating multiple applications or environments provides greater isolation and flexibility but may result in higher costs and greater management overhead. Uploading the application's source code or source bundle in the Elastic Beanstalk console is the most straightforward approach, while using CodePipeline provides a more advanced and automated deployment workflow.
