Colocation means your (or leased) hardware in a data center; the provider supplies space, power, cooling, and connectivity. Cloud means rented resources: no hardware ownership, pay-as-you-go, quick scaling. Choose by cost model, control needs, and how much operations you want to run.
Colocation
- You own or lease the servers; the DC provides space, power, cooling, and network.
- More control: OS, firmware, hardware upgrades on your schedule.
- Potential cost savings at scale: Predictable CapEx/OpEx; no per-VM markup.
- You manage: Hardware lifecycle, replacements, and (often) remote hands or on-site visits.
Cloud
- No hardware: Provision VMs, storage, and services on demand.
- Pay-as-you-go and quick scaling; good for variable or unknown load.
- Less hardware ops: Provider handles the physical layer; you focus on config and apps.
- Cost: Can be higher at steady, predictable scale compared to owned/colocated gear.
When to choose which
- Colocation: Steady or growing workload, team that can manage hardware, need for control or compliance, long-term cost optimization.
- Cloud: Variable load, fast experimentation, limited ops team, or need for many regions without building each.
Summary
Colocation = your hardware in a DC; cloud = rented resources. Choose by cost model, control, and how much you want to run. Many organizations use both (e.g. core in colo, burst or edge in cloud).
