Amazon Route 53
Amazon Route 53 is the managed DNS service from AWS. It translates domain names into IP addresses, manages domains and uses routing rules to control which server receives a request.
What is Amazon Route 53?
Amazon Route 53 is AWS’s DNS (Domain Name System) service. The DNS is the internet’s address book: it translates a human-readable domain name such as devrocks.de into the IP address of the server that responds to the request. Without the DNS, users would have to memorise long strings of numbers.
Route 53 handles this translation with high availability and speed. Furthermore, the service can register and manage domains, as well as use intelligent routing rules to control which server a request is actually directed to.
Features of Route 53
- DNS hosting: Management of all DNS records for a domain in so-called hosted zones.
- Domain registration: Domains can be registered and renewed directly via Route 53.
- Health checks: Route 53 monitors server availability and automatically redirects requests if a server fails.
- Routing strategies: Requests can be distributed across multiple destinations based on geographical proximity, latency or weighted distribution.
Intelligent routing
Route 53’s routing strategies go far beyond simple name resolution. With latency-based routing, a user is directed to the region with the fastest response time. With failover routing, traffic is automatically redirected to a failover system as soon as a health check detects a failure in the primary system. With weighted routing, a new application release can initially be delivered to a small proportion of users – the basis for low-risk canary deployments.
Availability
Route 53 is designed for 100% availability – a requirement that is particularly important for DNS: if name resolution is disrupted, the entire application is effectively inaccessible to users, even if the servers are running perfectly.
Route 53 for SMEs
Those who run applications on AWS benefit from managing their DNS there too: Route 53 can be linked directly to CloudFront distributions, load balancers and S3 buckets without having to maintain IP addresses manually. Health checks and failover routing increase reliability without the need to run additional software.
Frequently asked questions about Amazon Route 53
Route 53 charges around USD 0.50 per hosted zone per month and small amounts per million DNS queries. Health checks cost extra. For most companies, the monthly Route 53 costs remain in the single-digit euro range. Domain registrations are billed separately.
No. You can use Route 53 as a DNS service for a domain that is registered with any other registrar. To do this, enter the name servers of Route 53 with your registrar.
A health check regularly monitors the availability of a server or endpoint. If it detects a failure, Route 53 can automatically redirect the traffic to a functioning alternative system. This ensures that the application remains accessible even in the event of a server failure.
Yes, with geographic or latency-based routing, Route 53 routes requests to the region that offers the fastest response time for the respective user. This improves the performance of applications that are operated in several regions.
