Cloud Computing

Overview

Definition of Cloud Computing

is the on-demand delivery of computing resources such as servers, storage, , networking, software, , and intelligence over the internet. This model allows users to access services as needed, eliminating the need for investing in and maintaining physical data centers and servers. According to the National Institute of Standards and Technology (NIST), cloud computing is characterized by on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

Cloud computing encompasses three primary : Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides on-demand infrastructure resources like compute, storage, and networking, allowing organizations to utilize these resources without owning or maintaining physical hardware. PaaS offers a cloud-hosted platform for developing, running, and managing applications, enabling developers to focus on application development without managing the underlying infrastructure. SaaS delivers cloud-based applications via the internet on a subscription basis, allowing users to access software without installation or maintenance. These service models offer varying levels of responsibility and operational flexibility for organizations transitioning from traditional on-premises IT solutions to cloud-based environments.

Cloud computing promotes cost efficiency by converting fixed expenses into variable costs, as organizations pay only for the resources they consume. This flexibility supports a wide range of , including data backup, , software development, and analytics, making it an essential component of modern IT _.

Key Characteristics

Cloud computing encompasses various deployment models, including public, private, and hybrid clouds, each characterized by distinct advantages and disadvantages related to cost, security, , and control over resources.
