About
The Zonal Network Endpoint Groups mind map provides a technical architecture overview of Google Cloud's Zonal NEGs, covering 34 distinct nodes across 5 critical categories. This Zonal Network Endpoint Groups template serves as a professional cheat sheet for cloud architects managing zonal resources that represent collections of IP address and port combinations within a single subnet. The guide details how these endpoints function as backends for HTTP(S), TCP proxy, and SSL proxy load balancers. By exploring the 'Backend services' and 'Proxy load balancing' branches, users can understand the granular traffic distribution required for modern containerized applications. This Zonal Network Endpoint Groups mind map is essential for ensuring compliance with specific 'Restrictions', such as the requirement that IP addresses must be primary or alias IPs belonging to a specified instance.

How to use this template
Step 1
Import the template file
Download and open the .xmind file using Xmind desktop or the web application to view the full Zonal Network Endpoint Groups structure.
Step 2
Customize technical specifications
Modify the 'Limits' and 'Restrictions' nodes to reflect your specific organizational policies or project-specific network tiers.
Step 3
Export for documentation
Use the Xmind export feature to save the mind map as a PDF or PNG for inclusion in your system design documents or cloud architecture wikis.
Frequently asked questions
This template includes a comprehensive breakdown of Zonal NEG architecture, including its definition as a collection of IP/port combinations, backend service requirements, proxy load balancing mechanics, and a list of technical restrictions and limits for cloud infrastructure.
No. According to the 'Backend services' branch of this template, instance groups and zonal NEGs cannot be used as backends within the same backend service; all backends must be of the same type.
Zonal NEGs support 'RATE' balancing for HTTP(S) load balancing and 'CONNECTION' for TCP/SSL load balancing. As noted in the 'Limits' section, 'UTILIZATION' based load balancing is not supported.
Yes, this template is fully editable in Xmind. You can add your own project-specific IP ranges, subnet details, or custom architectural notes to the existing 34-node structure.
