# Elastic Beanstalk
### Overview
* Elastic Beanstalk is a developer-centric view of deploying an application on AWS
* It uses all the components we’ve seen before: EC2, ASG, ELB, RDS, etc...
* But it’s all in one view that’s easy to understand!
* We still have full control over the configuration
* Beanstalk = Platform as a Service (PaaS)
* Beanstalk is free but you pay for the underlying instances
* Managed service
* Beanstalk handles instance configuration / OS
* Deployment strategy is configurable but performed by Elastic Beanstalk
* Capacity provisioning
* Load balancing & auto-scaling
* Application health-monitoring & responsiveness
* Just the application code is the responsibility of the developer
* Three architecture models:
* Single Instance deployment: good for dev
* LB + ASG: great for production or pre-production web applications
* ASG only: great for non-web apps in production (workers, etc..)
• Support for many platforms:
* Go
* Java SE
* Java with Tomcat
* .NET on Windows Server with IIS
* Node.js
* PHP
* Python
* Ruby
* Packer Builder
* Single Container Docker
* Multi-Container Docker
* Preconfigured Docker
* If not supported, you can write your custom platform
### Health Monitoring
• Health agent pushes metrics to CloudWatch
• Checks for app health, publishes health events
