Imagine you rent a computer in the cloud
At first, you choose a small machine perfect for testing
But suddenly your app grows
Now your system becomes slow
What do you do?
That’s where Machine Types & Scaling come into play
Machine Types define the CPU, memory (RAM), and performance of your VM.
Choosing the right machine type ensures:
Types of Machine Families
Type | Use Case |
| General Purpose | Balanced workloads |
| Compute Optimized | High CPU tasks |
| Memory Optimized | Large databases |
| GPU Machines | AI/ML, graphics |
Example Machine Type
| --machine-type=e2-medium |
Includes predefined CPU & RAM
What is Scaling?
Scaling means adjusting resources based on demand
Two types of scaling:
Type | Description |
| Vertical Scaling | Increase power of one VM |
| Horizontal Scaling | Add more VMs |
Feature | Vertical Scaling | Horizontal Scaling |
| Method | Upgrade machine | Add more machines |
| Limit | Has limits | Highly scalable |
| Complexity | Simple | Requires load balancing |
Technical Example (Scaling VM)
| gcloud compute instances set-machine-type my-vm \ --machine-type=e2-standard-4 |
| gcloud compute instance-groups managed set-autoscaling my-group \ --max-num-replicas=5 \ --target-cpu-utilization=0.6 |
Automatically adds/removes VMs
