AWS - Route53 Essentials

If you ever wondered how the internet works, you should first probably learn how the domain name resolution works. Today, every business is digital business and more and more businesses want to digitize their business through websites and apps. Everything starts with a domain and managing a domain is one of the most critical aspect of running any good software-run business. It is increasingly important in an inter-connected world where all devices talk to each other all the time. This makes the DNS management as one of the most important feature of any public cloud because they host a wide variety of services.

If you take a very simple SaaS tool, it probably have a public facing marketing website at their root domain and their app is hosted with “app” subdomain. Similarly, their ticketing can stay in another domain, their payment service can be hosted by another SaaS provider, so the list is endless.

If your business is running in the cloud or thinking about moving to cloud, it is likely that the DNS management is one of the most critical part of your software and AWS Route53 can greatly simplify this effort. The “53” in the names stands for the standard port number of any DNS service. We will go over some cool features of Route53 in this article and understand why is it important.

Some of the notable features of Route53.

  1. Allows you purchase and manage domains for business and provide full-blown DNS management like any other domain registrar.
  2. If you don’t want to purchase or move your domain to AWS, you can use it to route traffic to your business application by utilizing the hosted zones.
  3. High-availability routing configuration allows you to route traffic to the working IP address as a fallback mechanism,
  4. Works for routing traffic within the VPC and makes your applications connect with each other better without using the IP addresses. IP addresses change frequently and it is a best practice not to use them as resource URL.

Conclusion

In short, Route 53 is great for managing domain names, directing internet traffic efficiently, and ensuring high availability and low latency for applications.
