VPS和VDS的区别

1. 虚拟专用服务器(VPS)：
VPS，顾名思义，是一种虚拟主机，在共享服务器中模拟专用服务器环境。它使用从操作系统级别工作的虚拟化层和一些流行的 VPS 选项，如 OpenVZ 使用基于 Linux 内核的技术。它提供了一些可扩展性，即可以从有限数量的资源开始，然后可以根据需要进行扩展。

2. 虚拟专用服务器(VDS)：
顾名思义，VDS 是一种虚拟机，让用户能够租用托管但专用的服务器来构建、部署和托管 Web 应用程序。它不与其他客户共享，因此不提供任何多租户环境。每个 VDS 都有自己的磁盘位置、CPU 分配、内存、带宽和操作系统。它通常取决于管理程序来创建逻辑分区级别。它还提供一组专用资源，一个人可以访问这些资源，而不需要与其他租户共享。

VPS和VDS的区别：

VPS	VDS
It is a VM on top of physical server that hosts VPS instances and shares host machine resources.	It provides remote dedicated server.
VPS is a server that is configured to host multiple server instances.	VDS instance takes up entire server.
It is more cost-effective as compared to VDS.	It is less cost-effective as compared to VPS.
It usually offers some scalability and predominant convenience as compared to VDS.	It does not offer scalability and predominant convenience.
It uses OpenVZ technology where OpenVZ is basically virtualization on OS level and its main advantage is speed of work.	It uses KVM technology that allows installing OS for visitors and VNC, that allows running virtual server like part of desktop computer.
In hosting terminology, virtual machines created with OS level virtualization is known as VPS.	In hosting terminology, virtual machines created with paravirtualization is known as VDS.
It offers less functionality as compared to VDS.	It offers better level of functionality as compared to VPS.
Its operation is managed and controlled by OS.	Its operation is managed and controlled by server hardware.
It has multi-tenant environment i.e., client has sole access to virtual private server environment, but they share hardware with two or more clients.	It has single-tenant environment i.e., only one client has access to hardware.
It is good for low load tasks such as to connect remote desktops and collective work with office applications, deployment of small e-commerce, corporate sites, etc.	It is not good for streaming video and audio apps, game servers, and high load apps with increased traffic, large e-commerce projects, etc.
