Cloud Architects and Network Engineers
Designing a hybrid cloud network architecture that requires internal name resolution
Use cases
About
The Cloud DNS mind map template provides a technical architecture for managing high-performance, resilient, global Domain Name System services. This 121-node cheat sheet covers the hierarchical distributed database structure used to translate readable domain names into numeric IP addresses. It specifically details the mechanics of an 'Authoritative server', the logic behind a 'Recursive resolver', and the implementation of 'Split horizon DNS' for internal and external network separation. Designed for cloud architects and network engineers, this Xmind template serves as a comprehensive reference for publishing zones and records without the operational burden of managing physical DNS servers. It outlines the differences between public and private managed zones, ensuring secure and cost-effective infrastructure management.
Terms and ConditionsWhen to use this template
DevOps Leads and Technical Trainers
Onboarding junior DevOps engineers to explain DNS record types and resolution flows
IT Security Auditors and Systems Administrators
Auditing existing cloud infrastructure for DNS security and access control compliance
How to use this template
Step 1
Import the DNS template
Open the .xmind file in Xmind desktop or web app to view the full 121-node hierarchy of Cloud DNS concepts.
Step 2
Customize zone configurations
Navigate to the 'Zones' branch and replace the generic descriptions with your specific public and private VPC network details.
Step 3
Define resource record sets
Use the 'Records' section to list your actual A, CNAME, and MX records, adjusting the 'SOA' serial numbers for version control.
Frequently asked questions
This template includes a detailed breakdown of DNS architecture, covering core concepts like authoritative vs. non-authoritative servers, zone types (public and private), record set management, and advanced configurations like split-horizon DNS and subdomain delegation.
Use this template to map out your VPC network visibility. You can customize the 'Private zone' nodes to reflect your specific internal IP mappings and use the 'Record sets' branch to organize your A, AAAA, and CNAME records.
Yes, this template is fully editable. You can add your own specific domain names, modify the 'TTL (time to live)' values in the records section, and expand the 'Access Control' branch to fit your organization's IAM policies.
The 'Split horizon DNS' structure is used to visualize how to serve different resource record sets for the same domain name depending on whether the query originates from the internal network or the public internet.
