IaaS, PaaS, and SaaS are cloud computing services that offer an alternative to on-premise IT solutions (where data, apps, and software run on in-house computer servers). On-premise (or on-prem) solutions are a rarity nowadays, but think of the olden days of Adobe InDesign on CD-ROM.
The graphic below provides a high-level overview of the primary differences between IaaS, PaaS, and SaaS from an IT perspective (i.e., this is primarily for the techies. All others to see layman's terms below).
What is IaaS? |
IaaS is a type of cloud computing that provides users with access to computing resources, like servers, storage, and networking. It allows users to rent these resources on a pay-as-you-go basis, so they don't need to invest in hardware or software upfront. IaaS customers have full control over the virtual machines and can install and configure their own software and applications. |
