AWS Elastic Beanstalk (EB)Running Microservices and Docker

Agenda

• Elastic Beanstalk vs DIY

• How to use Elastic Beanstalk

• Multi-Container Docker with AWS Elastic Beanstalk

• Recently added features

• Customer Feature - Sean O’Brien (Prezi)

Developer Challenges

• Complexity of deploying code, provisioning

and managing infrastructure

• Expertise and time needed to manage and

configure servers, databases, load

balancers, firewalls, and networks

• How to automate application scaling

What is Elastic Beanstalk?

AWS Elastic Beanstalk is an easy-to-use service for

deploying and scaling web applications and services.

AWS Elastic Beanstalk vs. Do It Yourself

Your code

HTTP Server

Application Server

Language Interpreter

Operating System

Host

Elastic Beanstalk configures each

EC2 instance in your

environment with the components

necessary to run applications for

the selected platform.

Focus on building your

application

Provided by you

Provided and managed by AWS Elastic Beanstalk (EB)

On-instance configuration

AWS Elastic Beanstalk vs. Do It Yourself

• Preconfigured Infrastructure

• Single Instance (Dev, Low Cost)

• Load Balanced, Auto Scaling (Production)

• Web & Worker tiers

• Elastic Beanstalk provisions necessary

infrastructure resources such as the load

balancer, auto scaling group, security

groups, database (optional), etc.

• Provides a unique domain name for your

application

(e.g.: youapp.regionx.elasticbeanstalk.com)

Infrastructure stack

Common Use Cases

• Websites

• API backends

• Mobile backends

• Asynchronous workers

Customers

Elastic Beanstalk Benefits

Fast & simple

to begin

Developer

productivity

Impossible

to outgrow

Complete

resource control

No additional charge to use.

You only pay for underlying AWS resources (i.e.: EC2 instances, S3, etc.)

How to deploy applications

1. Via AWS Management Console

2. Via AWS Toolkit for Eclipse and Visual

Studio IDE

3. Via AWS SDK’s and CLI

4. Via EB command line interface

$ eb deploy

Deploy Sample Application (EB CLI)

Initial application deployment workflow

$ git clone https://github.com/awslabs/eb-node-express-sample.git

Download sample application02

$ eb init

Create your Elastic Beanstalk app03

Follow the prompts to configure the

environment04

05 Create the resources and launch the

application

$ eb create

$ pip install --upgrade awsebcli

Install the AWS Elastic Beanstalk

command line interface (EB CLI)

01

Update Sample Application (EB CLI)

Update application workflow

Update your code01

$ git add .$ git commit –m “v2.0”$ eb deploy

Add & commit code to repository02

Open application once deployment

completes.

$ eb open

Docker with AWS Elastic Beanstalk

Docker Platform Configurations

• Single Container Docker

• Multi-Container Docker

Multi Container: Architecture

• Each environment has its own ECS Cluster

• Supports a single ECS Task definition per environment

• The ECS Task is defined in the Dockerrun.aws.json file

• Uses a flood scheduling mechanism

• Provides out of the box auto scaling for ECS Tasks

Benefits of using Multi-Container Docker with

Elastic Beanstalk

• Automation of capacity provisioning, load balancing,

scaling, and application health monitoring

• One stop management of your application in an

environment that supports range of services that are

integrated with Elastic Beanstalk, including but not

limited to VPC, RDS, and IAM.
