In this session, we introduce you to a solution for easily running a Docker-powered microservices architecture on AWS using Elastic Beanstalk. We will also cover the fundamentals of Elastic Beanstalk and how it benefits developers looking for a quick and scalable way to get their applications running on AWS with no infrastructure work required. Building a microservices architecture using Docker can require a lot of work, from launching and operating the underlying infrastructure to installing and maintaining cluster management software. With AWS Elastic Beanstalk’s multicontainer support feature, many of these tasks are simplified and abstracted away so you can focus on your application code. AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications and services developed with Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker." Learning Objectives: • Learn the basics of AWS Elastic Beanstalk • Understand how to use Elastic Beanstalk to run containerized applications • Learn how to use Elastic Beanstalk to start architecting microservices-based applications

Deploying Containers on EB

2. Agenda
 Elastic Beanstalk vs DIY
 How to use Elastic Beanstalk
 Multi-Container Docker with AWS Elastic Beanstalk
 Recently added features

3. 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

4. What is Elastic Beanstalk?
AWS Elastic Beanstalk is an easy-to-use service for
deploying and scaling web applications and services.

5. 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

6. 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

7. Common Use Cases
 Websites
 API backends
 Mobile backends
 Asynchronous workers

8. Customers

9. 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.)

13. 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

14. 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
environment
04
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

15. 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.
03
$ eb open

16. Docker with AWS
Elastic Beanstalk

17. 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.

18. I’ve built my containers, how do I…?
 Store my container images?
 Configure containers for Beanstalk?
 Test my config?
 Deploy to Beanstalk?
 Update my application?

19. Store your container images: Amazon ECR
 Beanstalk can interact with any Docker Repository
 Options include Dockerhub, Amazon ECR, and private
repos
 Amazon ECR allows access control via IAM for fine-
grained permissions
 Elastic Beanstalk can automatically authenticate with
ECR

20. Amazon ECR Registry Usage

21. Dockerrun.aws.json: Introduction
Specifies the version number as the value "2" for
multicontainer Docker environments
AWSEBDockerrunVersion01
An array of container definitions
ContainerDefinitions03
Mount points in the container instance that a container can use
Volumes02
"volumes": [
{
"name": "volumename",
"host": {
"sourcePath": "/path/on/host/instance"
}
}
],
Format:

Definition
The container definition and volumes sections of Dockerrun.aws.json use the same formatting as the
corresponding sections of an Amazon ECS task definition file.

23. Test your Beanstalk application locally
 Use EB “eb local run” command to run and test
dockerrun.aws.json application locally

24. Choose the right Beanstalk container platform
 Single Container Docker
 Multi-Container Docker

25. 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
