This scalable, highly available Domain Name System (DNS) web service translates these readable domain names into IP addresses that then connect the user’s request with all of the AWS infrastructure services that keep things moving in the digital realm.
How Does Amazon Route 53 Work?
When a user enters a registered domain name through a URL into a web browser, that’s when Amazon Route 53 takes over and gets to work to help connect the browser with your website or web application.
It starts the process by sending an automated request to the app’s or website’s server to verify that it's reachable, available and functional. This service also can notify you if that server is unavailable so you can choose to route internet traffic away from it.
Amazon Route 53’s Traffic Flow feature simplifies how you choose to route your global traffic, offering latency-based routing, geo DNS, geolocation and weighted round-robin. You can combine all of these routing types with DNS failover to deliver low-latency, fault-tolerant architectures.
Route 53’s Traffic Flow feature has a visual editor that helps you manage how users are routed to endpoints. This could be within a single AWS region or even globally. It can re-route traffic to an alternate location if your primary endpoint becomes unavailable.
What are Some of Route 53’s Other Benefits?
If you’re still not sold on using Amazon Route 53 to manage your web traffic, here’s a look at some of the other benefits it offers.
It’s cost-effective and scalable
Because Amazon Route 53 automatically scales up to handle large queries and scales back down for normal usage, you pay only for the resources you use. This includes the number of queries for your domains, zone hosting for those domains and other optional features, including health checks and traffic policies. You don’t pay upfront fees, nor do you have any minimum-usage commitments.
It’s fast and simple
Once you register to use AWS Route 53, you can quickly get up and running. The AWS Management Console or the easy-to-use Amazon Route 53 API helps you easily configure your DNS settings. You also can integrate the API into your web application. Once you’re running Amazon Route 53, its global network of DNS servers automatically route your users to the optimal location. This means they get low query latency, while you enjoy low update latency for DNS records management. Amazon Route 53 Traffic Flow’s features also contribute to this speed.
It’s highly available and reliable
Amazon Web Services offers distributed DNS servers to ensure that your users are consistently routed to your applications. And, as previously mentioned, Traffic Flow ensures failover protections so your users get where they need to go.
You can use it for internal routing.
All of the information I’ve just shared also applies to your organization's internal AWS account DNS.
Because Amazon Route 53 plays nicely with all of the other AWS web services, we want to be sure you understand all that Amazon Web Services has to offer. Be sure to check out other blogs in our AWS 101 series to learn more about these.
