What is Infrastructure-as-a-Service (IaaS)?
IaaS is the raw compute, storage, and networking layer of cloud. Here is the NIST definition, the three pillars, and how ZCP delivers real IaaS.
Engineering
What is Metal-as-a-Service (MaaS)?
Metal-as-a-Service turns a rack of physical servers into an API-driven pool. Here is when bare-metal provisioning matters and how ZCP delivers it.
Engineering
What is Platform-as-a-Service (PaaS)?
PaaS abstracts the runtime so you ship code, not servers. Here is the NIST definition, the trade-offs, and how ZCP delivers managed Kubernetes and Observability.
Engineering
What is Software-as-a-Service (SaaS)?
A technical decision-maker guide to the SaaS layer: NIST SP 800-145, the CAPEX-to-OPEX shift, and how SaaS providers run on IaaS underneath.
Engineering
What is software-defined networking (SDN)?
SDN separates the control plane from the data plane. A technical primer on the ONF definition, OpenFlow, and why cloud networking is impossible without it.
