Infrastructure as a Service (IaaS) in cloud computing is a service model that provides on-demand access to computing resources such as servers, storage, networking, and virtualization. Key points about IaaS include:
-
Cloud Computing Model: IaaS allows users to rent access to cloud infrastructure resources as individual services from a cloud service provider, eliminating the need for enterprises to procure, configure, or manage infrastructure themselves.
-
Resource Management: IaaS enables users to scale resources up and down rapidly according to their needs, driving faster time to market and offering cost savings.
-
Service Components: IaaS providers offer a range of services, including detailed billing, monitoring, log access, security, load balancing, clustering, and more.
-
Deployment Options: IaaS resources can be hosted in the public cloud (shared with other users), the private cloud (not shared), or the hybrid cloud (combination of both).
-
Virtualization: IaaS works on the principle of virtualization, allowing users to select the type and configuration of the infrastructure they require, with the system automatically creating digital versions of the underlying infrastructure.
IaaS is one of the four types of cloud services, along with Software as a Service (SaaS), Platform as a Service (PaaS), and serverless. It offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis, and is managed by the cloud service provider, allowing users to focus on their software and applications.
