Part 1: HTTP/1.1 vs. HTTP/2 on AWS Load Balancer - The Online Shopping Analogy
Imagine you're online shopping, and the website is like the store, your browser is you, and the AWS Load Balancer is the store manager.

HTTP/1.1:

One shopping cart, one item at a time: This is similar to how HTTP/1.1 works with the AWS Load Balancer. You (the browser) can only add one item (request) to your shopping cart (request) at a time and send it to the store manager (Load Balancer). The manager then directs you (sends the request) to a specific aisle (server) to get the item. If one item takes a long time to find (large file download), you have to wait with your cart until it's found, which can make shopping slow. This waiting also costs you money, as AWS charges you for each request.
HTTP/2:

Multiple carts, faster checkout: This is where HTTP/2 comes in. It's like having multiple shopping carts and a super-efficient manager. You can add several items (requests) to different carts (send multiple requests) at once. The manager then sends you (sends the requests) to different aisles (servers) simultaneously to find the items. You can potentially get all your items much faster, even if they're in different locations, making shopping quicker and smoother. Additionally, since you're sending fewer individual requests (fewer shopping trips), it can potentially save you money on AWS charges.
Benefits and Cost Savings:

Using HTTP/2 with the AWS Load Balancer can offer:

Performance: Websites load faster, leading to a better user experience.
Cost savings: By sending fewer individual requests, you potentially pay less in AWS charges.
Efficiency: The Load Balancer can handle more traffic with the same resources.
Quantifying the Savings:

The exact cost savings depend on factors like traffic volume, server setup, and pricing models. However, studies show HTTP/2 can improve website loading times by 20-30%, which can translate to significant savings in AWS charges by reducing the number of individual requests.
