Infrastructure as a service (IaaS)
NIST defines IaaS cloud computing as: “Where a consumer can deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure, but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).”
IaaS vendors offer online services that provide high-level APIs to their customers to manage and control the computing resources, location, data partitioning, scaling, security, backup, etc.
Additionally, IaaS clouds often offer a virtual-machine disk-image library, raw block storage, file or object storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles.Back to Glossary
