Decision Tree of Google Compute Engine (GCE)

Please find the attached image of the GCE Decision Tree. GCE is an example of Infrastructure as a Service (IaaS) and should be used when we need full control over the infrastructure. If full control over the infrastructure is not required, we can opt for other Google-provided cloud services. As shown in the image, we can select different options under GCE based on our specific needs.

• Single Compute Engine: Use for standalone workloads where scaling and high availability aren’t necessary.

• Stateful Managed Instance Groups: Use when your application requires persistence across VM instances (e.g., databases).

• Stateless Managed Instance Groups: Use for scalable, stateless applications (e.g., web servers).

• Predefined Machine Types: Use when your resource requirements fit predefined configurations and you want simplicity.

• Custom Machine Types: Use when you need fine control over CPU/memory configurations.

• Spot Machines/Preemptible VMs: Use for fault-tolerant workloads that can handle interruptions, to reduce costs.

• Shielded VMs: Use when security and VM integrity are the highest priority.

• Sole-Tenant Nodes: Use when compliance or licensing demands physical hardware isolation.

• Bare Metal Solution: Use when you need direct hardware access for specialized workloads that can’t be virtualized.

• VMware Engine: Use when you want to migrate or extend VMware workloads without changing the architecture.
