Difficulty: EasyPlanning Google Kubernetes Engine (GKE) Cluster Architectures

A cloud engineering team is planning a new Google Kubernetes Engine (GKE) deployment for a suite of stateless web microservices. The team needs to ensure the workload has high availability across multiple zones in a region while completely eliminating the operational overhead of provisioning, patching, and managing worker node infrastructure. Which TWO cluster architecture options should the team select to meet these requirements?

  1. Deploy the cluster using GKE Autopilot mode.Answer
  2. Configure a Regional cluster architecture.Answer
  3. C
    Provision a single-zone Zonal cluster to reduce regional control plane replication.
  4. D
    Configure GKE Standard mode with custom node OS images for manual kernel patch control.
  5. E
    Configure all node pools to use Spot VMs exclusively for non-preemptible database state.

Answer

The cloud engineering team should select GKE Autopilot mode and configure a Regional cluster architecture.
Deploying in GKE Autopilot mode fulfills the requirement to eliminate node management overhead by allowing Google Cloud to handle node provisioning, security patching, and auto-scaling. Selecting a Regional cluster architecture ensures high availability by replicating the control plane across multiple zones in a region and running worker nodes across those zones.

Step-by-Step Solution

1
Analyze the operational overhead requirement.
GKE Autopilot automates node management, OS patching, auto-repair, and scaling, eliminating worker node management overhead.
GKE Standard requires configuring and managing node pools, whereas Autopilot delegates cluster infrastructure operations fully to Google Cloud.
2
Analyze the availability requirement.
Selecting a Regional cluster deploys multiple control plane instances and node pools across several availability zones within the chosen GCP region.
Zonal clusters host control planes and nodes within a single zone, making them vulnerable to zonal outages.
