Why Route 53 with ELB integration in AWS? - Purpose & Use Cases

The Big Idea

What if your website could handle traffic spikes without you lifting a finger to update settings?

The Scenario

Imagine you have a website hosted on several servers, and you want visitors to reach it easily. You try to manually update your domain's IP address every time your servers change or scale.
