Amazon Route 53, provided by AWS, is a scalable and highly available DNS service. It converts user-friendly domain names like www.economize.cloud into IP addresses for your web servers, ensuring smooth customer access. But Route 53 offers more than just DNS services. It also includes domain registration, DNS management, and health checks, making it an all-encompassing tool for managing your online presence. Be it handling domain registrations, updating DNS records, or checking the health of your web services, Amazon Route 53 provides the essential tools and dependability you need.


How AWS Route 53 Manages DNS for Your Applications?

Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service designed to route end-user requests to internet applications. You can use AWS. Route 53 to perform three main functions in any combination: domain registration, DNS routing, and health checking.

Register Domain Names

Every website requires a unique name. Amazon Route 53 not only helps you register a domain name for your website or application but also ensures this crucial step in establishing your online presence is seamless and efficient. This makes getting your site up and running much easier.

Route Internet Traffic to Your Domain

When users type your domain name (like example.com) or subdomain (like acme.example.com) into their web browser, Amazon Route 53 plays a crucial role in connecting them to your website or web application. This ensures they reach the right resources seamlessly.

Check the Health of Your Resources

Amazon Route 53 is capable of sending automated requests to your resources, including web servers, to confirm they are accessible, available, and working properly. If a resource fails, you will get alerts and can redirect traffic from those problematic resources.

Key Capabilities of AWS Route 53 for DNS Management

In addition to being a Domain Name System (DNS) web service, AWS Route 53 offers several advanced features such as,

  • Route 53 Resolver: Route 53 allows you to set up recursive DNS for your Amazon VPCs across AWS Regions, VPCs in AWS Outposts racks, or any on-premises networks. You can establish conditional forwarding rules and endpoints to handle custom names from Route 53 private hosted zones or your own DNS servers.
  • Amazon Route 53 Resolver on Outposts Endpoints: Connect the Amazon Route 53 Resolver on your Outposts racks with DNS servers in your on-premises data centers via Route 53 Resolver endpoints. This ensures smooth DNS query resolution between the Outposts racks and your on-premises resources.
  • Route 53 Resolver DNS Firewall: Protect your recursive DNS queries using Route 53 Resolver. Set up domain lists and design firewall rules to filter outbound DNS traffic. This approach ensures that only permitted domains are accessed, adding an extra layer of security to your network.
  • Traffic Flow: Route 53 simplifies and reduces the cost of global traffic management. It enables you to direct end users to the best endpoint for your application by evaluating factors like geo proximity, latency, health, and more.
  • Amazon Route 53 Profiles: Using Route 53 Profiles, you can effortlessly manage and apply DNS settings across numerous VPCs and different AWS accounts, simplifying the process of DNS management.

Understanding Amazon Route 53 Pricing: Key Factors to Consider

Understanding Route 53’s pricing is crucial for effective cost management and budgeting of your AWS infrastructure. The service’s pricing encompasses various components, each caters to specific functionalities within the DNS and domain management spectrum. Let’s break down the key elements of Route 53’s pricing structure to give you a comprehensive overview of what you can expect to pay for when using this service.

  • Managing hosted zones: There is a monthly fee for each hosted zone managed with Route 53.
  • DNS query charges: Each DNS query incurs a charge, except for queries to Alias A records mapped to services like Elastic Load Balancing, CloudFront, Elastic Beanstalk, API Gateway, VPC endpoints, or S3 website buckets, which are free.
  • Domain registration: An annual charge applies to each domain name registered or transferred through Amazon Route 53.

Other pricing factors in Route 53 include,

Authoritative DNS Charges

When managing your domain’s DNS settings, AWS Route 53 provides a scalable and cost-effective solution. Here’s a brief overview of the costs associated with hosted zones, records, and DNS queries to help you budget effectively.

Hosted Zones and Records: A hosted zone includes up to 10,000 records. If you exceed this limit, an additional charge of $0.0015 per record per month applies. If your requirements exceed 500 hosted zones or 10,000 records per hosted zone, you should contact AWS for customized pricing.

AWS charges for hosted zones and records are as follows:

Hosted ZonesPrice
First 25 hosted zones$0.50 per zone per month
Additional hosted zones$0.10 per zone per month
Hosted zone creation chargeCharged at creation and first day of each month
Deletion within 12 hoursNo charge (queries still incur charges)
AWS Route 53 Pricing for Hosted Zones

Records: For records exceeding this limit (ie. beyond 10,000 records):

RecordsPrice
Each record beyond 10,000$0.0015 per record per month

DNS Queries: DNS query prices vary based on the type of query and are prorated. Queries on private hosted zones are free, but public-hosted zones incur charges:

Query TypeFirst 1 Billion QueriesOver 1 Billion Queries
Standard Queries$0.40 per million queries$0.20 per million queries
Latency-Based Routing Queries$0.60 per million queries$0.30 per million queries
Geolocation/Geoproximity Queries$0.70 per million queries$0.35 per million queries
IP-Based Routing Queries*$0.80 per million queries$0.40 per million queries
AWS Route 53 Pricing for DNS Queries

No fees are charged for storing up to 1,000 IP (CIDR) blocks. Above this limit, storage incurs $0.0015 per month (prorated hourly) for each additional IP block. Queries for mismatched domain/subdomain names or record types, and queries for non-existent records, are charged at standard rates.

Alias Queries: Alias records allow you to route traffic to AWS resources without incurring query charges, provided the alias target is an AWS resource (e.g., Elastic Load Balancers, CloudFront distributions, etc.) and not another Amazon Route 53 record.

Free DNS Queries:

  • Domain/subdomain name and record type match an alias record.
  • The alias target is an AWS resource.

Charged DNS Queries:

  • An alias target is a non-alias record in the same hosted zone.

API Calls Between Route 53 and Amazon S3: Amazon Route 53 console can generate API calls to Amazon S3, such as listing buckets. These calls may incur charges under your S3 billing.

Authoritative DNS Query Logs: There is no charge for authoritative DNS query logs themselves. However, enabling DNS query logging incurs Amazon CloudWatch charges for data ingestion, storage, and analysis in the US East (Virginia) Region.

Traffic Flow:Traffic Flow policies are charged based on policy records. Per policy record per month costs around $50.00.


Health Check Costs
