Difficulty: EasyDeploying Cloud Load Balancers and Configuring Cloud DNS

Your organization is hosting a backend microservice on Compute Engine instances within a Virtual Private Cloud (VPC) network. The microservice communicates over raw TCP traffic on port 8080 and requires internal regional traffic distribution without SSL offloading or layer 7 path routing features. Which load balancer should you deploy?

  1. Regional Internal Network Passthrough Load BalancerAnswer
  2. B
    Regional Internal Application Load Balancer
  3. C
    Global External Application Load Balancer
  4. D
    Global External Proxy Network Load Balancer

Answer

The Regional Internal Network Passthrough Load Balancer is the correct choice because it provides internal Layer 4 TCP load balancing within a GCP region.
The Regional Internal Network Passthrough Load Balancer is designed specifically for internal VPC workloads operating at Layer 4 (TCP/UDP) within a single region. It efficiently balances TCP traffic without proxy overhead.

Step-by-Step Solution

1
Identify the network scope requirement
Traffic must remain private inside the VPC within a single region (Internal regional scope).
Internal workloads should not use external load balancers.
2
Determine the protocol layer
The application uses raw TCP on port 8080 without requiring HTTP path routing or SSL offloading.
Layer 4 passthrough balancing is sufficient and optimal for raw TCP applications.
3
Select the matching GCP load balancer product
Choose a Regional Internal Network Passthrough Load Balancer.
It natively supports internal regional TCP traffic distribution.

Key Concept

Selecting GCP Load Balancers based on traffic direction (Internal vs External) and network layer (Layer 4 TCP vs Layer 7 HTTP/HTTPS).
