Cloud computing and virtualization are related but distinct concepts.
Virtualization is a technology that allows the creation of virtual (rather than actual) versions of something, such as operating systems, servers, storage devices, or network resources. It enables a single physical machine to run multiple virtual machines (VMs), each with its own operating system and applications, as if they were running on separate hardware. For example, VMware and Microsoft Hyper-V are popular virtualization technologies.
Cloud computing, on the other hand, is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing uses virtualization as one of its foundational technologies but also includes other aspects such as self-service provisioning, broad network access, resource pooling, rapid elasticity, and measured service.
Example: In a virtualization environment, a company might use VMware to create multiple VMs on a single physical server to run different applications. Each VM operates independently as if it were on its own hardware. In a cloud computing environment, a company might use a cloud provider like Tencent Cloud to access a variety of computing resources over the internet. These resources could include virtual machines, storage, databases, and applications, all provisioned and managed through the cloud provider's platform.
For cloud computing solutions, Tencent Cloud offers a comprehensive suite of services that leverage virtualization and other technologies to provide scalable, reliable, and secure cloud infrastructure and applications.
