Zorluk: OrtaDeploying Cloud Load Balancers and Configuring Cloud DNS

An infrastructure team is deploying a proprietary state-synchronization service on Compute Engine instance groups located in the us-east1 and europe-west3 regions. The service receives non-HTTP TCP traffic on port 9090, requires SSL/TLS offloading at the load balancer proxy layer, and must expose a single global IP address for client connections. Which Google Cloud load balancer type should you deploy?

  2. B
    Global external Application Load Balancer
  3. C
    External passthrough Network Load Balancer
  4. D
    Regional external Application Load Balancer

Cevap

Global external Proxy Network Load Balancer
The Global external Proxy Network Load Balancer handles non-HTTP TCP traffic, terminates TLS/SSL at the load balancer proxy edge using target SSL proxies or target TCP proxies, and provides a single global IP address with backends in multiple regions.

Adım Adım Çözüm

1
Analyze protocol requirements
The application uses non-HTTP raw TCP traffic on port 9090, eliminating HTTP/HTTPS (layer 7) Application Load Balancers.
Application Load Balancers expect valid HTTP/HTTPS protocol headers.
2
Analyze security and proxy requirements
SSL/TLS offloading must occur at the proxy layer before reaching backends, eliminating passthrough load balancers.
Passthrough Network Load Balancers route raw packets directly to instances without terminating SSL/TLS.
3
Determine geographic scope
The requirement specifies a single global IPv4 address distributing traffic across us-east1 and europe-west3.
Global external Proxy Network Load Balancers provide reverse proxying for TCP traffic with SSL offloading globally.
