Cloud computing refers to the practice of using remote servers hosted on the internet to store, manage, and process data, rather than using local servers or personal computers. Cloud computing allows users to access a wide range of computing resources, such as computing power, storage, and software, on-demand and pay only for what they use, similar to a utility model like electricity or water. Cloud computing services are typically provided by cloud service providers, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP), among others.
Virtualization, on the other hand, is a technology that allows multiple virtual instances of operating systems, applications, or other computing resources to run on a single physical server or host. It abstracts the underlying hardware resources and creates a virtual layer that separates the software from the physical infrastructure. Virtualization enables more efficient utilization of computing resources by consolidating multiple workloads on a single physical server, reducing hardware costs, and enabling better scalability and flexibility.
Cloud computing often relies on virtualization as a key technology to provide scalable and flexible computing resources to users. Virtualization enables cloud service providers to create virtual machines (VMs) or containers that can be provisioned and managed dynamically based on user needs, allowing for efficient resource allocation and utilization in a multi-tenant environment. Cloud computing and virtualization have revolutionized the way computing resources are provisioned, managed, and utilized, offering benefits such as cost savings, agility, scalability, and accessibility to businesses and individuals alike. They are widely used in various industries for a wide range of applications, including web hosting, data storage, big data processing, software development, and disaster recovery, among others.
