3. Challenge - Migrating a Web-App to the Cloud
🎯 How do I move my web-app
to the cloud
++ 🦾 design for high availability
++ ⚡ scale dynamically
++ 🎲 deploy application versions safely
++ ⚽ keep the OS patched
++ 😎 modernize it over time?

• Dashboard with detailed
application metrics
• Log events with CloudWatch
Logs streaming
• Easily enable AWS X-Ray for
analyzing and debugging

11. • Automatically deploy to Elastic
Beanstalk with each Code Commit.
• Create a CI/CD pipeline using the
CodePipeline/Elastic Beanstalk
integration.
• Integrate Elastic Beanstalk into an
existing CI/CD pipeline

• Containerize an app
automatically
• Gradually adopt a service-
oriented architecture
Modernize with
containerization
• Run .NET Core apps in EB
Linux environments and save
30% or more vs. Windows
• Convert apps from .NET
Framework to .NET Core to
run on Elastic
Beanstalk/Linux
Replatform from
Windows to Linux

12. Shared Application Load Balancer capability
§ Share an ALB among EB
environments
§ Reduce ALB costs while
modernizing your app
§ Use Host-based and Path-
based rules to serve traffic to
multiple environments or
services hosted on Beanstalk
or ECS

16. What is AWS Elastic Beanstalk?
Automatically handles:
Ø Infrastructure provisioning and configuration
Ø Ongoing management of infrastructure
Ø Deployment
Ø Load balancing
Ø Auto scaling
Ø Health monitoring
Ø Automated Updates
Ø Analysis and debugging
Ø Logging

1. Application: “Container” that
encapsulates code, infra, etc.
2. Application version: Code that you
create and deploy
3. Platform: Language runtimes to run
the application.
Platforms containing the most
popular runtimes (Java, .NET, Go, …)
as well as Docker images, allowing
you to bring your own
4. Environment: Group of AWS
infrastructure elements to support
running the application

Beanstalk

18. Application versions
q Every deployment is its own unique version
q All versions stored in Amazon S3
q Allows easy rollback to a previous version
without having to back out committed code
changes
q Allows you to promote versions across
different environments within an
application
