What Is Cloud Computing? | Microsoft Azure
Cloud computing is a revolutionary approach to IT resources that offers numerous benefits for organizations. It brings about a significant departure from traditional thinking and introduces seven key advantages: cost savings, speed, global scalability, enhanced productivity, improved performance, reliability, and security. Cloud computing encompasses various types and models tailored to meet specific needs.
The deployment of cloud services involves choosing between a public cloud, private cloud, or hybrid cloud. Public clouds are operated by third-party providers, offering computing resources over the internet. Microsoft Azure serves as an example of a public cloud, where the provider manages all infrastructure elements, and users access services through a web browser. Private clouds are exclusive to a single business or organization and can be physically located on-site or hosted by third-party providers. Such clouds maintain services and infrastructure within a private network. Hybrid clouds combine public and private clouds, facilitating data and application sharing, enhancing flexibility, deployment options, infrastructure optimization, security, and compliance.
Cloud services are categorized into four primary types: infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS). IaaS involves renting IT infrastructure, such as servers, storage, and networks, from a cloud provider on a pay-as-you-go basis. PaaS provides on-demand environments for developing, testing, delivering, and managing software applications, abstracting the underlying infrastructure complexities. SaaS delivers software applications over the internet, with cloud providers managing both the application and infrastructure, including maintenance and upgrades. Serverless computing focuses on building app functionality without the need for continuous server management, as the cloud provider handles setup, capacity planning, and server maintenance.
Cloud computing finds applications in various areas, and many individuals and organizations are already utilizing it without realizing. Online services for email, document editing, media streaming, gaming, and file storage are powered by cloud computing. Cloud services cater to the needs of startups, corporations, government agencies, and non-profit organizations worldwide.
