AWS Elastic Beanstalk

• Platform as a Service (PaaS)

A Typical Web Application (3-tier) has an ELB and a ASG & a Database (+Cache). This is a standard design. This Application can be made using 3 ways!

- Manually setting up resources (HARDEST!) - Using CloudFormation or Amazon CDK (Mid Complexity but better to maintain) - Using Amazon Beanstalk (Simplest!)

• Managing Infrastructure
• Deploying code
• Configuring all Databases, Loadbalancers, exact
• Scaling Concerns
• Most WebApp have same architecture (ALB + ASG)
• All developers want is for their code to run

Elastic Beanstalk is a sdeveloper centric view of deploying an application on AWS. It uses all the components we’ve seen before. (EC2, ASG, ELB, ROS). But its all in 1 view, that’s easy to make sense of. We still have full control of the configuration!!

There are 3 architecture models: - Single Instance Deployment: Good for DEV env.

• LB + ASG: Great for Production & Pre-Production. - ASG Only: Great for non-webApps in production [other intermediate microservices!]

Elastic Beanstalk suppports many platforms: Go, Java SE, Java with Tomcat, .NET with windows server, Node JS, PHP, Python, Ruby, Packer Builder If not supported you can write custom platforms as well!

• Health agent pushes metrics to cloudwatch as well
• check for app health, publish health events.
