Frequently Asked Questions

What is IaaS?

Cloud delivery of compute, storage and networking on demand, where you manage the operating system and above while the provider runs the hardware.

IaaS, PaaS or SaaS?

IaaS gives the most control, PaaS removes server management, and SaaS delivers a finished application; see the PaaS and SaaS pages.

How do I choose an IaaS provider?

Compare regions and compliance, instance types including GPUs, pricing and egress costs, ecosystem and support; developer clouds such as DigitalOcean and Hetzner suit simple workloads. In the EU, the Data Act's cloud-switching rules have applied since 12 September 2025 and phase out switching charges by 12 January 2027, according to law-firm summaries.
