Intro to AWS Elastic Beanstalk@dduvnyak

What is Elastic Beanstalk?

PaaS

Deploy scalable web apps without worrying about infrastructure

Elastic Beanstalk Features

• Deployment, scaling and monitoring of three-tier web apps/services

• EB provisions and manages infrastructure while allowing control of it

• Preconfigured app containers (that are customizable)

Supported platforms

Elastic Beanstalk core concepts

Application

Environments• Infrastructure resources

(such as EC2 instances, ELB load balancers, and Auto Scaling groups)

• Runs a single application version at a time for better scalability

• An application can have many environments (such as staging and production)

Application versions• Application code• Stored in Amazon S3• An application can have

many application versions (easy to rollback to previous versions)

Saved configurations• Configuration that defines

how an environment and its resources behave

• Can be used to launch new environments quickly or roll-back configuration

• An application can have many saved configurations

Environments

Two types: - Single instance - Autoscaling environments with load balancing

EB provisions infrastructure (load balancers, DBs, autoscaling groups, security groups)

Preconfigured application containers

Focus on your code

Elastic Beanstalk configures EC2 instances from the ground up to run your application

No need for manual configuration

Your code

HTTP server

Application server

Language interpreter

Operating system

Host

App versions and saved configurations

Deployment Options

• Git / EB CLI • AWS Management Console (Web) • AWS Toolkit for Eclipse and Visual Studio

CLI Deployment

1. Initialize your repository for Elastic Beanstalk> eb init

2. Commit any changes> git commit -a -m 'Add changes'

3. Create and launch the application> eb create

CLI Deployment

Deploying updates: 1. Make code changes 2. Push changes to EB:> git commit -a -m 'Add new changes' > eb deploy

3. Monitor deployment status:> eb status

Demo: Deploy a PHP app to EB
