Elastic Beanstalk

• Developers usually don’t want to manage infrastructure, they want to deploy code (lol :)
• Elastic Beanstalk is a developer centric view of deploying applications on AWS
• It uses all the previous components: EC2, ASG, ELB, RDS, etc.
• These components can be configured and instantiated via configuration files
• Beanstalk is entirely free, we only pay for the underlying infrastructure
• Beanstalk is managed service, which means:
  • Instance configuration, OS is handled by AWS
  • Deployment strategies are configurable but they are performed by Beanstalk
• The application code is the developer’s responsibility (obviously)
• There are 3 architecture models for Beanstalk:
  • Single Instance deployments, recommended for development
  • LB + ASG: great for production or pre-production
  • ASG only: great for non wen applications
• Beanstalk has 3 components:
  • Application
  • Application version: each deployment gets a version
  • Environments
• We deploy application versions to environments and can promote application versions to the next environment
• We can rollback to previous versions of the application
• We have full control over the lifecycle of the application
• Beanstalk has support for many applications:
  • Go
  • Java SE
  • Java with Tomcat
  • .Net on Windows Server with IIS
  • Node.js
  • PHP
  • Python
  • Ruby
  • Packer
  • Single Container Docker
  • Multi-container Docker
  • Pre-configured Docker
• There is an option for custom platform if the stacks above are not what we are looking for
