The difference between VPS, VDS

Is the VPS virtual server and VDS virtual server the same. What is the difference between them? I feel that it is similar, but I just use different software to set up.

  1. VPS and VDS are almost exactly the same in function. On the surface, there are the same thing, but there are still essential differences. The main difference between the two is the underlying operating system and the virtual technology used.

    1. Technically
    vds uses full virtualization technology (Full-), which provides a completely independent virtual server environment, which is equivalent to a real physical machine. Various types of operating systems can be run on VDS at the same time. Typical technical platforms include VMware, Hyper-V, etc.
    VPS is mainly based on software layer virtualization technology, that is, operating system-level virtual technology. It can not use the virtual hardware environment, but it needs to be modified by guest OS. Typical technical platforms include Virtozzo, Openvz.
    It, it is worth mentioning that in reality, everyone is used to classify Xen on VPS, but the semi -deficiency technology () it uses is more similar to VDS in terms of characteristics, so it is more ambiguous.

    . The resources are on
    vds to CPU, memory and bandwidth resources. Once allocated, it is always used for itself. The hardware resources will be allocated before running, and the distributable resources shall not exceed the maximum resource that can be distributed by physical machines, that is, if the physical machine is 2G memory, it must not be assigned 4G. Have SWAP memory.
    VPS to CPU, the occupation of resources such as memory and bandwidth is shared, and each VPS will affect each other. Its resource allocation is not restricted. For example, if the physical machine is 2G memory, you can virtually allocate 4G, but it is not significant. No SWAP memory.
    So from the perspective of resource allocation, VDS is obviously a more stable and reliable choice. VDS is rare in virtual service providers, and VPS is the most popular at the moment, and the price is relatively cheap.

    . In terms of quantity
    The virtual quantity, VDS is more suitable for applications that are more suitable for stable reliability. About 3-4 VDS. Because VPS is relatively small at the bottom, the execution efficiency is significantly higher than the full virtual, so VPS running on a physical machine can usually run 20-40 VPS. Theoretically V can be virtually used as a server to virtue of hundreds of independent operating systems, but its results can be imagined, which is of little significance.

    . Safety
    VDS is completely independent, whether it is hardware resources or the system, so it usually does not affect other VDS on the same desk server when being attacked. VPS has always been shared resources on the same desk server, so when a VPS is attacked, it will directly affect the operation of all other VPS. In addition, because VPS does not have SWAP memory, once the memory is used than the distributed memory, it will cause VPS to directly crash. Because VDS has SWAP memory, it will not crash immediately when it is severely exceeded, but the system response It will be very slow. Generally speaking, both enhance the ability, safety and reliability of physical machines.

    5. In terms of cost
    In comparison in various aspects, VPS costs lower than VDS.

  2. Popular speaking:
    The same point: VPS and VDS have their own independent IP and hard disk space, memory, and network bandwidth.
    Different points: VPS is a software virtual operating system desktop is not an independent operating system, and VDS is an independent operating system;
    It use VDS technology server, you can install different operating systems independently. Users restart the user restarted. The behavior does not affect the normal use of other users, the isolation of the virus is also better, and the confidentiality of the file is better;
    The server using VPS technology can only install a operating system. Affects the normal use of other users.

  3. Vollar is the name of basic circulation units in the VDS ecosystem, and it is also its only commercial and financial transmission medium.
    In addition to the account records and payment, Vollar can also activate VID, bidd VAD advertising position,
    > Incentive master node operation (ensure the stability of the network), and operate smart contracts in the system.
