- AWS Elastic Beanstalk is a fully managed platform that allows users to deploy and scale web applications quickly. It automates infrastructure provisioning, deployment, load balancing, auto-scaling, and health monitoring. - It supports deploying containerized and non-containerized applications. Users can deploy applications using CDK, CLI, or IDE plugins and integrate with CI/CD pipelines. - Elastic Beanstalk provides high availability and scalability out of the box. It allows users to safely rollout application updates using different deployment strategies. - It serves as a starting point for modernizing applications and adopting distributed architectures. Features like shared load balancing allow deploying applications across different compute services.

12. Shared Application Load Balancer capability
§ Share an ALB among EB
environments
§ Reduce ALB costs while
modernizing your app
§ Use Host-based and Path-
based rules to serve traffic to
multiple environments or
services hosted on Beanstalk
or ECS

1. Application: “Container” that
encapsulates code, infra, etc.
2. Application version: Code that you
create and deploy
3. Platform: Language runtimes to run
the application.
Platforms containing the most
popular runtimes (Java, .NET, Go, …)
as well as Docker images, allowing
you to bring your own
4. Environment: Group of AWS
infrastructure elements to support

18. Application versions
q Every deployment is its own unique version
q All versions stored in Amazon S3
q Allows easy rollback to a previous version
without having to back out committed code
changes
q Allows you to promote versions across
different environments within an
application
