Alright, before we dive into AWS route 53, let's get a grasp on how the internet really flows, shall we?

So, you're sitting there, in your comfy chair, wanting to check out what's new on the NEWS. Naturally, you'd type "" into your browser. Easy peasy, right? But what if, every time you wanted to visit Google, you had to remember something like… I bet even your phone number is easier to recall! But wait, that's where our hero, DNS, enters the scene. Imagine DNS as this cool translator that takes the tongue-twisting "" and elegantly turns it into the familiar "". Thanks to DNS, you don’t need to remember those funky numbers; it's got your back!

Now, you might be wondering, why the numbers in the first place? Well, every device connected to the internet has a unique address, much like how every home has a unique postal address. These are IP addresses. There's the elder sibling, IPv4 (that looks like and the sophisticated younger one, IPv6 (which has a more complex look). But we'll save that family drama for our AWS VPC.

Okay, so back to you wanting to search on Google. When you hit enter after typing "", a series of super-fast events happen:

  • Your computer shouts out to the router, "Hey, I wanna visit Google!"
  • The router then hollers at your Internet Service Provider (ISP), "Get this person to Google, pronto!"
  • Your ISP, like a well-trained postman, zips your request across the vast landscape of the internet using 'packets'. These packets are like tiny envelopes carrying your message.
  • Finally, the Google server receives your request, packages up the information you need, and sends it back.
You see Google’s homepage, all in the blink of an eye!

And oh, while we're still here, there are these things called 'records' – A record, CNAME record, and a few others. Think of them as the rulebook that the DNS uses. But hey, let’s not spill all the beans now. We'll dive into those waters once we're in the deep end with AWS Route 53. That's the internet for you! Simple, right? (Or at least, we tried to make it sound that way!) ????

There's a whole galaxy of DNS providers out there, from GoDaddy and Cloudflare to Google Domains. But when you pair AWS Route 53 with other AWS services, it's like adding a turbocharger to your engine – there are some unique advantages that can really supercharge your web experience!

Here's an interesting tidbit: When Facebook started, people often abbreviated it as "FB" and typed to reach the site. However, was owned by the American Farm Bureau Federation. To secure the domain, Facebook shelled out a whopping 8.5 million dollars! This showcases the internet's and DNS names' incredible influence and worth.
What is Route 53?
Amazon Route 53 is a highly available and scalable cloud-based Domain Name System (DNS) web service offered by Amazon Web Services (AWS). At its core, Route 53 connects user requests to infrastructure running in AWS, like EC2 instances or S3 buckets, but can also route to external infrastructure. It translates friendly domain names, such as "," into IP addresses, ensuring your users can access your applications and services.
