Cloud computing is a transformative technology paradigm that has revolutionized the way computing resources are accessed, delivered, and managed. At its core, cloud computing involves the provision of a broad range of computing services over the internet, allowing users to access and utilize resources without the need for owning or maintaining physical infrastructure. Cloud computing services are typically categorized into three main models: Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS)

Cloud computing is like your local machine which is located somewhere in else with a grantee of running all the time. You don't need to worry about maintenance of continuous of power supply and other necessary stuff. Also you can increase your resource according to your need with the rent so that you can focus on your business without worrying about maintaining those hardware.

- Cloud computing makes powerful computing resources and software accessible to anyone with an internet connection, regardless of their budget or location. A startup can use cloud-based AI tools to analyze data without needing expensive hardware and software. - The cloud provides a platform for rapid experimentation and agile development. Developers can test new ideas and deploy applications quickly, while teams can collaborate seamlessly in real-time. Researchers can develop and share complex scientific models in the cloud, accelerating scientific discovery.

Not everything can be stored and accessed through a local device. In the era of interconnected computing, cloud computing is sort of services that are valuable to a person who would otherwise engage his device to do that all the way. You want servers, data warehouses, envs, web hosting, you can get benefited from knowing cloud computing. Apart from being beneficial to individuals, cloud comuting as a skill is very valuable and top corporations from around the world prefer to hire candidates with knowlegde of cloud computing

Cloud computing works like a behind-the-scenes maestro. You rent computing resources - servers, storage, databases, software - from a cloud provider like Google Cloud Platform, Amazon Web Services, or Microsoft Azure. These resources reside in massive data centers scattered across the globe, accessible anytime, anywhere through the internet. You pay only for what you use, making it scalable and cost-effective

Cloud computing is essentially renting infrastructure and building upon it. This removes an entire class of problems (like scaling, stability, etc) for both small and big businesses.

The internet is utilized to provide cloud computing services. It is made up of three major parts: Cloud services are classified into three types: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). The abstraction of physical hardware into virtual resources, allowing for flexible allocation and utilization, is known as virtualization. Internet Delivery: Users can access services and resources remotely via the internet, providing for scalability, cost-effectiveness, and accessibility from anywhere.

The more you learn about the cloud, the more you understand why companies are migrating to the cloud. Essentially, you use the infrastructure owned and managed by cloud services providers such as AWS, GCP and Azure. Whatever be your task, you don't need any resources of your own as you can simply rent them and just pay for what you need, and for the amount of time you're using them. You can use it for storage, content delivery, creating virtual machines, performing data visualization and much more, without worrying about running and maintaining your own hardware or servers.

Typically you pay someone else for the amount of computing power you need. It can scale easily from one computer to another entire environment to run an enterprise-level business. Typically it is more cost-effective to rent the infrastructure you need than to build and manage your own.
