Deploy, Scale and Manage your Application with AWS Elastic Beanstalk

2. Agenda • Elastic Beanstalk Introduction • Elastic Beanstalk vs. DIY • Getting started with Elastic Beanstalk • Demo – Sample Application • Custom Platforms • Best Practices • Deployment options • Managed Updated • Auto Scaling • Other tips

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 • Lack of consistency across teams

4. What is Elastic Beanstalk? AWS Elastic Beanstalk is an easy-to-use service for deploying, scaling, and managing 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. 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.)

8. Common use cases Websites API backends Mobile backends Asynchronous Workers

9. How do I get started with Elastic Beanstalk?

10. Information required to deploy application 01 02 03 04 Region Stack (container) type Single Instance Load Balanced with Auto ScalingOR Database (RDS) Your code Optional Supported Platforms Custom Platforms Create and manage your own custom Elastic Beanstalk platforms for greater control over the AMI, metadata, and configuration options.

11. Building blocks Application Application Versions ( V1, V2, …,Vx) Environment 1 Environment 2 Environment .. n

12. 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

13. 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

14. 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

15. 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.)

16. Demo

18. Custom Platform • Create and manage your own custom Elastic Beanstalk platforms • Get greater control over the AMI, metadata, and configuration • Enforce and manage standardization/best practices across environments (without the need for .ebextensions)

19. Custom Platform For example: you can now create your own platforms on Ubuntu or Red Hat Enterprise and customize your instances with languages/frameworks currently not supported by Elastic Beanstalk e.g. Rust, Sinatra etc. For example: you can now create your own platform that runs multiple Docker containers, uses encrypted AMIs or custom disk layouts e.g. multiple volumes, EFS mounts etc.

20. Custom Platform Creating a Custom Platform: • Uses Packer: an open-source toll for creating machine images • Methods: EB CLI, API, SDK • Platform Definition archive • Packer template: • Platform definition file: platform.yml • Builder: • EB CLI: • eb platform init • eb platform create • An environment called 'eb-custom-platform-builder-packer' is created in order to build the platform. This environment will not terminated automatically. Once your platform creation has completed, you can terminate this builder environment using the command “eb terminate”

21. Custom Platform Using a Custom Platform in a user environment: • Methods: AWS Management console, EB CLI, API, SDK • EB CLI: • eb init • select option “Custom Platform” for the question “select a platform” • eb create • Console:

22. Best practices • Deployment options • Managed Platform Updates • Auto Scaling • Other tips

Auto Scaling Min/Max instances Availability Zones Scaling cooldown Triggers based scaling Trigger measurement (CPU utilization, network traffic, disk activity, instance health) Trigger statistic Measurement period Breach duration Thresholds Breach scale increment Time-based scaling Name Min/Max instance Occurrence (One-time, Recurrent) Recurrence (CRON expression- 30 8 * * 3)

60. 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
