AWS Elastic Beanstalk is the fastest and simplest way to get an application up and running on Amazon Web Services. Developers can simply upload their application code and the service automatically handles all the details such as resource provisioning, load balancing, auto-scaling, and monitoring. This session shows you how to connect your Git repository with Amazon Web Services, deploy your code to AWS Elastic Beanstalk, easily enable or disable application functionality, and perform zero-downtime deployments through interactive demos and code samples.

and a TOOLBOX for
DEPLOYMENT, ENVIRONMENTS and INFRASTRUCTURE

4. You can, with AWS Elastic Beanstalk!

5. Okay let’s get started!

6. Components of a Web App
• Three tier architecture:
• Web Server
• App Server
• Database
• Components
• Application Compute
• Database Engine
• Storage and Delivery

7. Components of a Web App

• Web Server
• App Server
• Database
• Components
• Application Compute
• Database Engine
• Storage & Delivery

8. AWS Elastic Beanstalk - EB
• Easily deploy, monitor, and scale applications.
• Infrastructure provisioned and managed by EB.
You maintain complete control.
• Preconfigured application containers that are
easily customisable.

9. AWS Elastic Beanstalk Environment
• Two tiers:
• Web Server
• Worker
• Two types:
• Single instance
• Load balanced, auto scaling
• Configures Amazon Route 53
and provides a domain name
https://yourapp.elasticbeanstalk.com

10. Application Versioning
Saved Configurations
Allow for easy duplication for
A/B testing or non-disruptive
deployments
Application Versions
All versions are stored
durably in Amazon S3.
Code can also be pushed
from a Git repository!

11. AWS Elastic Beanstalk Instance Configuration
Your code
HTTP server
Application server
Language interpreter
Operating system
Host
• Each Amazon EC2
instance comes with the
necessary components
to run applications
• No more worrying about
logging into instances to
install and configure your
app stack
Focus on building your app

12. Deployment Options
1. Via the AWS Management Console
2. Via Git / EB CLI
3. Via the AWS Toolkit for Eclipse and
the Visual Studio IDE
$ pip install awsebcli

13. Example: CLI workflow
Initial app deployment:
$ git init . $ git add .
Initialize your Git repository01 Add your code04
$ eb init $ git commit –m "v1.0"
Create your Elastic Beanstalk app02 Commit05
Follow the prompts to configure the
environment
03
Create the resources and launch the
application
06
$ eb create

14. Example: CLI workflow
Update your app:
Update your code01
$ git add .
$ git commit –m "v2.0"
$ eb deploy
Push the new code02
Monitor the deployment progress03
$ eb status

22. Customisation via .ebextensions
• Customize AWS Elastic Beanstalk resources
• Examples:
• Deploy your resources in a custom VPC
• Configure your auto-scaling rules
• Much more
• Simple Chat:
• Custom VPC
• Configure ELB for websockets

23. Live Demo

24. Components of a Web App
• Three tier architecture:
• Web Server
• App Server
• Database
• Components
• Application Compute
• Database Engine

25. Amazon RDS
Amazon RDS
• Fully managed relational database
• Automated full daily backups and 5 min
incremental point in time recovery
• Highly available through Multi-AZ with
automatic failover to standby database
• Easily create cross-region read replicas
• Managed underlying storage layer with
configurable IOPS performance
Aurora MariaDB

26. Using Elastic Beanstalk with Amazon RDS
• Support for running Amazon RDS instances in your AWS Elastic
Beanstalk environment.
• RDS connection details are made available to application as
environment variables
• Database is tied to
beanstalk environment’s
lifecycle
