About
The Internet Network Endpoint Groups mind map provides a technical architecture overview of how Google Cloud external HTTP(S) load balancers integrate with custom origins. This template covers 52 nodes of critical infrastructure data, detailing how an 'Internet NEG' functions as a global resource for third-party or on-premises infrastructure. It serves as a definitive 'Internet Network Endpoint Groups cheat sheet' for cloud architects, explaining how to leverage Google Edge infrastructure to terminate user connections and utilize Cloud CDN for external endpoints. The guide specifically highlights that while these groups are used as a 'Backend service', they do not support traditional 'Health checks', instead returning an HTTP 502 response if the endpoint becomes unreachable. This resource is essential for teams moving traffic across Google's private backbone to improve reliability and decrease latency for non-GCP hosted services.

Frequently asked questions
An Internet NEG is used to define a backend for a Google Cloud external HTTP(S) load balancer when the actual content origin is hosted outside of Google Cloud, such as on-premises or with another cloud provider. It allows you to use Google's global edge infrastructure and Cloud CDN for these external endpoints.
Yes, it clarifies that a 'Backend service' using an internet NEG does not support standard Google Cloud health checks. If the endpoint becomes unreachable or the FQDN cannot be resolved, the load balancer will return an HTTP 502 (Bad Gateway) response.
No. According to the 'Backend service' specifications in the template, all backends on a single backend service must be of the same type. You cannot combine internet NEGs with zonal NEGs or instance groups.
Yes, this template is fully editable. You can customize the nodes for 'Pricing', 'Quota', and 'Limitations' to match your specific project requirements or regional constraints within the Xmind application.
