Zorluk: OrtaPlanning Network Load Balancing, Cloud DNS, and Cloud CDN

A financial technology company is planning the network architecture for a global payment processing service. External payment gateways will communicate with backend Compute Engine instances deployed across multiple Google Cloud regions using a proprietary, non-HTTP raw TCP protocol. The company wants to terminate incoming TCP connections at the Google network edge close to clients to reduce latency and distribute incoming traffic across the multi-region backend instances. Which Google Cloud load balancer should the company select?

  1. External Proxy Network Load BalancerCevap
  2. B
    External HTTP(S) Load Balancer
  3. C
    Internal Passthrough Network Load Balancer
  4. D
    Cloud DNS Private Zone

Cevap

The External Proxy Network Load Balancer is the correct choice because it supports global external non-HTTP TCP traffic and terminates client TCP connections at the Google edge network.
The External Proxy Network Load Balancer is designed for external, non-HTTP raw TCP or SSL traffic. It operates globally, terminating TCP connections at Google's network edge to optimize latency before forwarding connections to Compute Engine backends in multiple regions.

Adım Adım Çözüm

1
Analyze protocol requirements
The application uses a proprietary, non-HTTP raw TCP protocol.
This rules out Layer 7 HTTP(S) load balancers which require standard HTTP/HTTPS traffic.
2
Analyze network entry and scope requirements
Traffic originates from external clients on the public internet and must be load balanced across multiple regions with edge TCP termination.
This rules out internal load balancers and regional passthrough load balancers.
3
Select matching Google Cloud load balancing service
The External Proxy Network Load Balancer meets all requirements for global reverse proxying of non-HTTP TCP traffic.
It offloads TCP connections at Google edge locations and proxies the connections to multi-region backend instance groups.
