AWS route 53 domain resolving question


Hi all I now hosting the services on-prem, and now DR set going to host in AWS. The business requirement is to resolve the unified single service FQDN, from on-prem, AWS and also third party cloud.

  1. Can Route53, doing like global load balancer able to resolve the unifed service URL, and Route53 can smart enough redirect traffic based on policy setting (example weighting)

  2. How to ensure on-prem DNS and AWS domain entry always sync?

  3. For multi cloud situation, how Router53 and other cloud vendor able to resolve the service unified URL, say azure.

To address your requirements for resolving a unified service FQDN across on-premises, AWS, and other cloud providers, Route 53 can indeed be used as a global load balancer and DNS service. Here's how you can achieve this:

  1. Global Load Balancing with Route 53: Route 53's Global Load Balancer (GLB) feature allows you to distribute traffic across multiple regions and AWS and on-premises resources. You can configure a DNS record (e.g., CNAME or ALIAS) in Route 53 with a unified service FQDN that points to multiple endpoints in different regions or clouds. Route 53 will intelligently distribute traffic based on policies like weighted, latency-based, or geolocation-based routing.

  2. Syncing On-Premises DNS with Route 53: To ensure synchronization between your on-premises DNS and Route 53, you can set up a DNS resolver on your on-premises network that forwards DNS queries to Route 53. This can be achieved by configuring a DNS resolver or DNS forwarder on your network infrastructure, such as on your router or DNS server. The DNS resolver will forward queries for your unified service FQDN to Route 53, ensuring that both on-premises and AWS environments resolve the same unified URL.

  3. Resolving Unified URL across Multiple Clouds: For resolving a unified URL across multiple cloud providers, such as Azure, you can use Route 53's capability to create a DNS record that points to resources hosted in different clouds. You can configure the DNS record to resolve to endpoints in AWS and Azure, allowing traffic to be distributed based on your routing policies. This way, Route 53 acts as a centralized DNS service for your unified URL across multiple clouds.

It's important to note that achieving seamless integration and synchronization between different DNS providers and cloud platforms requires careful planning, configuration, and coordination. You'll need to ensure that appropriate DNS records and routing policies are set up correctly in each DNS service and cloud provider.

Additionally, consider using appropriate security measures like network connectivity, firewalls, and DNS security (e.g., DNSSEC) to protect the integrity and availability of your DNS resolutions across different environments.

Consulting the documentation and support resources of Route 53 and the respective cloud providers can provide further guidance on specific configurations and best practices for your multi-cloud DNS resolution requirements.
