Introduction to Amazon Route 53¶
Amazon Route 53 is a scalable and highly available Domain Name System (DNS) web service designed to route end users to Internet applications by translating human-friendly names into numeric IP addresses. The addition of Amazon Route 53 authoritative DNS service in AWS GovCloud (US) enhances the landscape for U.S. government agencies, contractors, and sensitive enterprise applications needing compliance with stringent regulatory standards, handling their DNS within dedicated AWS regions while retaining the flexibility of AWS’s extensive cloud offerings.
What is AWS GovCloud?¶
AWS GovCloud (US) is a specialized AWS region that addresses the unique compliance and security requirements of U.S. government agencies and other entities, such as educational institutions and regulated industries. With its more stringent compliance frameworks — including FedRAMP, ITAR, and DoD SRG — GovCloud provides a secure environment for processing, storing, and transmitting federal data. By integrating Route 53 into this ecosystem, AWS is enabling a more cohesive infrastructure for customers requiring localized and compliant DNS services.
Key Features of Route 53 in AWS GovCloud¶
The launch of Amazon Route 53 authoritative DNS service in AWS GovCloud (US) brings several powerful features that customers can leverage:
Authoritative DNS Service¶
With the availability of authoritative DNS capabilities all within the GovCloud Regions, AWS users can manage DNS records without relying on external commercial AWS regions. This facility is key for applications that must remain compliant with security standards and ensures that DNS queries are handled more efficiently within the U.S. jurisdiction.
DNS Query Logging¶
An essential feature for security and compliance, DNS query logging, allows users to capture and analyze concerns about traffic patterns. It provides insights into how applications interact with users and helps detect anomalous behavior, enhancing security posture by enabling audits and investigations when necessary.
DNSSEC Signing¶
DNS Security Extensions (DNSSEC) is a critical feature that adds a layer of security by allowing DNS responses to be securely signed. With DNSSEC, customers can protect against data compromise, phishing attacks, and other malicious activities, ensuring the integrity and authenticity of DNS responses. This is particularly crucial for government organizations that handle sensitive data.
Routing Types¶
Route 53 supports a range of routing options tailored to meet various application needs, including:
– Simple Routing: Basic routing to a single resource.
– Weighted Routing: Distributing traffic across multiple resources based on specified weights.
– Latency-based Routing: Reducing latency by routing user requests to the nearest endpoint.
– Geo-location Routing: Directing users based on geographic location.
By utilizing these routing types, GovCloud users can optimize application performance and ensure a consistent user experience.
Getting Started with Route 53 in AWS GovCloud¶
Starting with Route 53 in AWS GovCloud is straightforward, thanks to the AWS Management Console and API. Below are the steps to get your public hosted zones up and running.
Creating a Public Hosted Zone¶
- Log in to the AWS Management Console.
- Navigate to Route 53.
- Select “Hosted Zones.”
- Click “Create Hosted Zone.”
- Enter the Domain Name you wish to create a hosted zone for and select “Public Hosted Zone.”
- Configure settings and click “Create.”
Configuring Alias Records¶
Alias records are one of the unique features of Route 53 that allows users to point their domain names directly to AWS resources, simplifying the DNS configuration process. Here’s how to set them up:
- In your Hosted Zone, select “Create Record.”
- Choose “Alias” as the Record Type.
- Select the appropriate Target from the list of integrated AWS resources (e.g., S3, ELB).
- Complete any additional settings and hit “Create Record.”
Migration from Commercial AWS Regions¶
For existing users of Route 53 in commercial AWS regions, migrating their DNS records to AWS GovCloud (US) is a strategic process. Key points for migration include:
- Take Inventory: Document all existing hosted zones, record types, and configurations.
- Replicate Configuration: Utilize templates or manual configuration steps to create hosted zones and records in GovCloud.
- Test Thoroughly: Before fully switching DNS records, utilize DNS testing tools to ensure that performance meets expectations.
- Cut Over: Once verified and tested, change NS records at the registrar to point to the new GovCloud hosted zones.
Pricing Overview¶
Understanding the financial aspect of utilizing Route 53 in AWS GovCloud is essential for planning and budgeting. Key components of the pricing model include:
- Hosted Zones: A flat monthly fee per hosted zone.
- DNS Queries: Charged based on the number of queries made each month.
- Health Checks: Optional health checks for endpoints can incur additional costs.
