With on-demand computing (ODC), users can get computing resources whenever they need them. The resources could be kept up by the user's company or supplied by a provider of cloud services. When the services are offered by a third party, like a cloud hosting company, the phrase cloud computing is frequently used as a synonym for on-demand computing.
The efficient management of organisations' shifting demand was a difficulty that the on-demand corporate computing paradigm was created to address. Maintaining enough resources to satisfy peak demands can be expensive since an enterprise's need for computational power might occasionally be unanticipated. Additionally, retaining limited resources while decreasing expenses means that there may not be enough resources to handle peak loads. The on-demand concept gives an organisation the flexibility to quickly scale computational power up or down as needed.
Three characteristics of the model define it: scalability, pay-per-use, and self-service. The computer resources are flexible, metered, and simple to get, if the asset is an application programme that facilitates team member collaboration or offers additional storage.
How Cloud Computing Supply On-Demand Functionality?
Delivering hosted services through the internet is referred to as "cloud computing" in general. These services are broken down into many classes of cloud computing applications and resources.
For instance, on-demand computing frequently uses cloud computing techniques like managed hosting services, cloud storage, and backup services. These techniques include:
- Infrastructure as a service (IaaS)
- Software as a service (SaaS)
- Desktop as a service (DaaS)
- Platform as a service (PaaS)
- Infrastructure as a service (SaaS).
