About
The Load Balancer URL Maps mind map template provides a technical architecture overview of how Google Cloud HTTP(S)-based load balancers route traffic. This 24-node Load Balancer URL Maps template covers the essential logic used by External and Internal HTTP(S) Load Balancing and Traffic Director to direct incoming requests. It specifically details how a URL map functions as a configuration resource to manage traffic flow to a 'Default backend service' or 'backend bucket' based on host and path-based routing. Users can explore the relationship between 'Host rule' and 'Path matcher' components to understand how URL segments are mapped to specific backends. This Load Balancer URL Maps cheat sheet is an essential reference for cloud architects and DevOps engineers managing complex cloud networking environments, ensuring that every HTTP(S)-based load balancer is correctly configured with its mandatory URL map.

How to use this template
Step 1
Import the configuration map
Open the .xmind file in Xmind to view the structured breakdown of URL map components and protocol rules.
Step 2
Map your backend services
Replace the generic backend service nodes with your specific project service names to visualize your actual routing logic.
Step 3
Validate host and path rules
Use the Host rule and Path matcher branches as a checklist to ensure your cloud configuration matches your architectural design.
Frequently asked questions
A URL map is a Google Cloud configuration resource that directs requests to backend services or buckets. It uses the host name and path portions of each URL to determine the correct destination, ensuring traffic reaches the intended resource based on predefined rules.
No, as noted in the 'URL maps and protocols' section, URL maps do not provide protocol redirection (like HTTP to HTTPS). All client protocol redirection must be implemented by the backends themselves, though the map can handle both protocols simultaneously.
A 'Host rule' directs requests sent to specific host names to a single path matcher. The 'Path matcher' then defines the specific relationship between the path portion of that URL and the backend service or bucket that should serve the request.
Yes, every HTTP(S)-based load balancer must have a URL map. This template outlines the mandatory nature of the resource and how it serves as the central routing logic for both external and internal load balancing instances.
