2. AWS Elastic Beanstalk
Easily deploy, monitor, and scale three-tier web applications and services.
Infrastructure provisioned and managed by EB – but you maintain complete control.
Preconfigured application containers that are easily customizable.
Support for these platforms:

3. Elastic Beanstalk object model
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
Applications are the overarching container of multiple Environments, Application Versions, and Saved Configurations
Environments contain actual resources like EC2 Instances/ELBs/ASGs
Application Versions are actual code versions.
We get questions about limits a good amount on increasing Application Version limits. Best practice is to trim those. Do not use EB as an application storage mechanism. They should be using CodeCommit or something for version control. Customers will have to trim old App Versions.

4. Elastic Beanstalk environment
Two types:
Single instance
Load balancing, auto scaling
Two tiers (web server and worker)
Elastic Beanstalk provisions necessary infrastructure resources such as load balancers, auto-scaling groups, security groups, and databases (optional)
Configures Amazon Route 53 and gives you a unique domain name
(For example: yourapp.elasticbeanstalk.com)
Beanstalk is a managed service. Let Beanstalk take care of Infrastructure management and customers just deal with the code.
Single Instance – usually for dev/test

5. On-instance configuration
Focus on building your application
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
No more worrying about logging into instances to install and configure your application stack
Never manually log in and configure EC2 instances. Let Beanstalk do it for you – use ebextensions

6. Application versions and configurations
All versions are stored durably in Amazon S3. Code can also be pushed from a Git repository!
Saved configurations
Save these for easy duplication for A/B testing or non-disruptive deployments
Application lifecycle
Enable auto-deletion of application versions based on application version count or application version age

7. Customizing Your Environment
Elastic Beanstalk manages your AutoScaled environments
Manual changes will be lost on scaling events
ebextensions lets you customize your AutoScaling fleet
Place multiple config files into “.ebextensions” folder
YAML and JSON support
~/my-app/
|-- .ebextensions
| |-- environmentvariables.config
| `-- healthcheckurl.config
|-- .elasticbeanstalk
| `-- config.yml
|-- index.php
`-- styles.css
Ebextensions lets you:
Customize:
API options with option_settings
Installed packages
Groups
Users
Sources
Files
Run custom commands
Ensure services are running
We parse the .config file with both a JSON and YAML parser.

8. Deployment options Via the AWS Management Console Via EB CLI
Via the AWS Toolkit for Eclipse and the Visual Studio IDE
$ eb deploy
This used to be $ git aws.push
The new eb CLI will let you clone environments, run local environments, etc.
Eb deploy takes the most recent check in from your local git repo and deploys that to EB.
If someone in the room says that they’re using git aws.push, then it’s time to upgrade. Git aws.push is from the EB cli v2.6 which has been deprecated.

9. Deployment configuration
Your code
Region 01
Stack (container) type 02
Single instance
Load balanced with Auto Scaling 03 OR
Database (RDS) 04
Optional

10. Example: CLI workflow Prerequisites:
AWS account – your access and secret keys
EB CLI
Linux / Unix / Mac / Windows : Python 2.7 or 3.4 (Not 3.5)
A credential file containing info from 1
Git 1.66 or later (optional)

11. Example: CLI workflow Initial app deployment:
$ git init .
$ git add .
Initialize your Git repository 01
Add your code 04
$ eb init
$ git commit –m “v1.0”
Create your Elastic Beanstalk app 02
Commit 05
Follow the prompts to configure the environment 03
Create the resources and launch the application 06
$ eb create

12. Example: CLI workflow Update your app: Update your code01
$ git add .
$ git commit –m “v2.0”
$ eb deploy
Push the new code 02
Monitor the deployment progress 03
$ eb status

13. Example: Docker container
Three ways:
Dockerfile (image built on instance).
Dockerrun.aws.json (manifest file that describes how to run the Docker image).
Application archive (should include Dockerfile or Dockerrun.aws.json file).
Benefits:
Enables high-fidelity deployments.
You own the runtime. You can use any language or framework, even those not currently supported by Elastic Beanstalk (such as Scala and Clojure).
Dockerfile
Dockerrun.aws.json
Importance of highlighting docker is that you can now use Beanstalk to provision infrastructure and not be bound to the default solution stacks. With Beanstalk multi-container environments (that run on ECS), you can even have more than one container deployed onto ECS for you.

14. Example: Docker container
Using the EB command line tool:
$ git init .
Initialize your Git repository 01
$ git add Dockerfile
Add your code 04
$ eb init
Create your Elastic Beanstalk app 02
$ git commit –am “v1.0”
Commit 05
Follow the prompts to configure the environment and copy Dockerfile 03 06
Create the resources and launch the application
$ eb create

15. Monitoring Enhanced Health Reporting Unique to Elastic Beanstalk
No additional cost
Daemon process running on each EC2 instance in your environment
More detail on each individual instance
EB CLI: eb health
id status cause
Overall Info Command is executing on 3 out of 5 instances
i-bb65c Pending % of CPU is in use. 24 % in I/O wait
Performing application deployment (running for 31 seconds)
i-ba65c Pending Performing initialization (running for 12 seconds)
i-f6a2d Ok Application deployment completed 23 seconds ago and took 26 seconds
i-e8a2d53b Pending % of CPU is in use. 52 % in I/O wait
Performing application deployment (running for 33 seconds)
i-e81cca Ok
Canary deployments
Detect failures early and roll back

16. Deployments – In Batches
Batched Deployments
Customize a percentage of instances to be deployed to
Deploy to X% and only continue if the instances become healthy
Automated rollback on failures
Canary deployments
Detect failures early and roll back

17. Deployments – Zero Downtime
Swap URLs
Create a new environment for an existing application
Deploy your updated application code to the new environment
Use the “Swap Environment URLs” feature to transition users to the new production environment
Swaps the CNAMEs of environments (appname.elasticbeanstalk.com) with another CNAME with a different environment. This allows blue green deployments (red/black).

18. Security Considerations
Deploy within a VPC
Understand security controls created for you
Create well defined permissions in IAM

19. Security Updates
AWS Elastic Beanstalk provides updates to platform configurations periodically
Your responsibility to update your individual environments
Update Platform Version in place
Beanstalk solution stacks are locked to a specific AMI and release version. Hence, you need to upgrade your stacks like this to get the newest security patches.
We do NOT do this for customers.

20. Benefits of Elastic Beanstalk
Focus on your application
Focus on what makes your business unique
Focus on innovation, not undifferentiated heavy lifting
Spend developer time in the right place
Automate as much as you can
Zero downtime deployment
