О шаблоне
The Load Balancer Backend Services mind map template provides a technical architecture overview for cloud infrastructure engineers managing External HTTP(S), SSL Proxy, and TCP Proxy services. This 144-node cheat sheet details how backend service resources direct traffic to instance groups or network endpoint groups (NEGs). It specifically covers the 5-tuple hash algorithm used for request distribution and the critical role of 'Health checks' in monitoring backend instance health. Users can explore the nuances of 'Traffic distribution' logic, including how balancing modes like backend utilization and requests per second (RPS) interact with capacity scalers to prevent regional overloads. The template serves as a definitive guide for configuring 'Session affinity' and timeout settings to ensure stable client-server connections across distributed environments.

Как использовать этот шаблон
Шаг 1
Import the template file
Open the .xmind file in Xmind desktop or the web app to access the full 144-node backend service hierarchy.
Шаг 2
Map your infrastructure components
Replace the generic 'Backends' and 'Named ports' nodes with your specific instance group names and service port configurations.
Шаг 3
Define health check parameters
Customize the 'Health checks' branch to reflect your specific polling intervals and success thresholds for your backend instances.
Часто задаваемые вопросы
This template includes a comprehensive breakdown of backend service configurations, covering architecture, traffic distribution modes, session affinity settings, health check protocols, and timeout parameters for various load balancer types like SSL and TCP proxies.
It explains how the balancing mode (utilization, rate, or connections) determines backend capacity. It also details how the system handles regional overflows and how the 'capacity scaler' can be used to drain services or limit instance utilization.
Yes, while the terminology (such as 'INTERNAL_SELF_MANAGED' and 'NEGs') aligns closely with Google Cloud Platform (GCP), the core concepts of health checks, 5-tuple hashing, and session affinity are applicable to most major cloud providers.
Use the 'Timeout setting' branch to distinguish between standard HTTP(S) request/response timeouts and specific idle timeouts for WebSockets or SSL/TCP proxy connections, ensuring your backend service resource matches your application's needs.
