• Managed Updated
• Auto Scaling
• Other tips
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
• Lack of consistency across teams
What is Elastic Beanstalk?
AWS Elastic Beanstalk is an easy-to-use service for
deploying, scaling, and managing 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
Elastic Beanstalk benefits
Fast & simple
to begin
Developer
productivity/agility
Impossible
to outgrow
Complete
resource control
No additional charge to use Elastic Beanstalk.
You pay only 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 SDKs 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
03
$ eb open
Sample application details
• Application dependency management
• Configuring/customizing an environment using ebextensions
• Choosing a remote source repository: AWS CodeCommit
• Adding additional AWS resources (e.g.: DynamoDB, SNS, SQS, etc.)

Managed Platform Update
Configure your environment to automatically upgrade to the latest
version of a platform during a scheduled maintenance window.
• Permissions
• Maintenance Window
• Minor and Patch Updates
Key benefits:
• Automated Upgrades
• No/Minimal downtime
• No/Minimal impact on capacity
• Flexibility of manual updates
• Instance replacement

Other tips
Logs, Metrics, & Alarms• Enable log rotation to automatically publish logs to S3.
• Understand metrics available for your environment and what they mean.
• Set up alarms to automatically monitor critical metrics and send notifications when
metrics are outside normal operating range.
• Enable Amazon Route 53 health checks and alarms
Tag your environments• Makes it easy to find resources belonging to a given environment.
• Can be used to monitor costs associated with a given environment and/or
application.
• AWS Elastic Beanstalk automatically tags environments with:
• Environment Name
• Environment ID
