What a compute instance is (in plain terms)
A compute instance is a virtual machine that behaves like a dedicated server for your workload. You get isolated resources, root access, and a predictable environment compared to shared hosting.
When compute instances are the right choice
- You need root access to install packages or run Docker.
- Your app outgrew shared hosting performance limits.
- You want predictable resource allocation and upgrade paths.
- You need a stable server for staging, CI, or internal tools.
Specs that actually matter
CPU and performance consistency
A “bigger” CPU spec is not useful if performance is inconsistent. Look for clear CPU core allocation and transparent plan tiers.
