Hey guys!!
I would like to explain the concept of Route53 in simple....Let us walk together through my blog..
Firstly Route53 in aws denotes the DNS as a Service.Here's how..
When the user sends any request to the application the flow is as follows
Internet Gateway -> Route53 -> In the Public Subnets we have NAT and Load Balancers -> Private subnets
From the flow Route53's work is like when an user for an instance tries to access the flipkart.com , amazon.com so on ,it has to convert the domain name i.e like flipkart.com into an ip address of a load balancer.Its because its hectic for the users to remember all the ip address instead of accessing them like a piece of cake by the domain names.So the users always tries to access only through the Domain names.Thus the Route53 takes care of this translation into a load balacers's ip address.
How to register our domain names in AWS Route53?
1.If you already have a domain name purchased form GoDaddy or some other else ,aws can integrate it ,or if you are going to purchase a new domain
2.This step is mandatory i.e Hosting Zones in which the aws can have the DNS records that maps the domain name into an ip address
-----------------Its how the Route53 functions--------------------
Also it performs Health Checks by sending request like 2mins once or 5mins once to web server to check the condition of the web servers,if it is good ,it will forward the traffic,and if we have more instances ,it will balance the traffic..
Thank you for your valuable time here .But its a simple concept of Route53 ,there is also a vast complexity too...Happy reading!!
