Intro to Horizontal Scaling, Load Balancing, Immutable Infrastructure with AWS

This video demonstrates how to implement horizontal scaling and immutable infrastructure on AWS EC2, showing both the theory and practical implementation.

You'll learn:

• How horizontal scaling works with load balancing
• The concept of immutable infrastructure and why it's important
• Creating custom Amazon Machine Images (AMIs)
• Setting up multiple EC2 instances from a custom image
• Configuring Nginx as a load balancer
• How to distribute traffic across multiple application instances
• Practical implementation of rolling updates using immutable infrastructure

The video takes a hands-on approach, showing manual implementation to help understand the core concepts, though in production you'd typically automate these processes using tools like Packer and Terraform.

Don't worry about following along with the video step-by-step yet - just watch to understand the concepts and overall process. This will give you a solid foundation for when you implement these patterns in your own infrastructure.
