VPS similar miner

1. It is suggested that you can learn about asproex (Apollo), which is the world's first stock exchange for securities companies, and supports multi currency trading

2. 1、 VPS host
VPS host, also known as VPS, virtual private server< In terms of usage:
the VPS host is equivalent to a computer with complete functions. When opening a VPS host, you can choose to install the corresponding operating system, deploy your own environment, and install any program according to your needs. VPS host uses remote login desktop for operation management, which is more free and powerful than cloud virtual host. Most users use VPS host for self configuration, website building, traffic webpage, upload and download, etc. VPS host self built suppliers basically provide a control panel for users to install the operating system, restart, and reload; Some small proxy providers only provide remote login information
2. Technology:
the VPS host uses cloud technology to divide the physical server into multiple virtual private servers. Each VPS host has its own dedicated IP address, independent system, independent memory, independent hard disk, independent CPU and independent bandwidth< Second, cloud virtual host:
cloud virtual host can also be called virtual host, virtual space and virtual space< The main differences between the virtual machine and the VPS host and the cloud server are as follows:
1. In terms of usage:
the virtual machine is used by users to upload website data and programs directly, without user deployment environment. It usually supports a variety of site building environments by default, and users can use it by uploading the site building program installation directly. Most cloud virtual hosts use control panel or FTP tools for users to upload. Mature cloud virtual host vendors will provide more convenient control panel<
2. Technology:
virtual machine uses cloud computing technology to divide a real physical computer host into multiple logical storage units. Each unit has no physical entity, but each logical storage unit can work on the network like a real physical host, and has a separate domain name and IP address (or shared IP address) and complete Internet server function< Third, cloud server
cloud server is more popular in recent years, using the most advanced cloud technology applications
1. Usage: the use of cloud server and VPS host is the same, but the technology is different, so the performance of cloud server will be better than that of cloud server
2. Technology: the cloud server adopts cluster cloud technology, and uses cluster server to build many small computers similar to independent servers. The cloud server uses a mirror file, and the hardware can be upgraded and configured automatically, and the data can be backed up automatically. The security and stability of the cloud server are higher than that of the VPS host
in a word, virtual machine < VPS < cloud server, users can use cloud server to build VPS and cloud virtual machine, and can use VPS to build cloud virtual machine, but can't use cloud virtual machine to build VPS and cloud server, and can't use VPS to build cloud server. The overall performance of cloud server is higher than that of VPS and virtual machine, and VPS is higher than virtual machine.

3. 80 points, I'll explain it to you well

virtual machine - it refers to a kind of original solution that a server virtualizes many users for people to use. There are many problems in actual use

VPS - it is a kind of enhanced virtual machine to isolate memory from users, allocate bandwidth control, and solve many problems in actual use
virtual machine However, it is still limited by many underlying technologies, and many requirements can not be
implemented, such as the real allocation of CPU use, the expansion of user resources, etc.

virtual machine - in fact, the concept of cloud has developed a lot of applications. If virtual machine is cloud, then
virtual machine VPS is a cake. Can two clouds be combined into one big cloud and two cakes put together or two
cakes This is a conceptual problem
for users, high resource utilization, complete user isolation from the bottom layer, and arbitrary expansion of resources at any time
VPS virtual machine each machine should have 5% - 10% of the resources to use Run the underlying system and
resource allocation software, and a virtual machine needs 5% of the resources of a machine for resource allocation
it can achieve 99% resource utilization at most

the difference between virtual machines is that VPS is a virtual machine that can have independent IP, and the biggest feature of a virtual machine is that it can be infinitely expanded and can be configured arbitrarily At present, only some game servers of Siemens Tencent are used internally

4. It's hard to make it clear.
the so-called cloud is actually more of the same concept. The clouds come and go, which makes others not understand<
virtual host is to give you a folder to use,
VPN is better than virtual host
if you rent a single room house for the virtual host,
then VPS means you rent a house
an independent host means that you can buy a house,
whether you rent a room, a flat or a house, you can live in it
that means that you can build a website, but there are differences in the size, capacity and function of the website,
but each space provider is different, so there is no unified difference
the virtual hosts of some space vendors can do many websites, while the virtual hosts of some space vendors can only do one website
different space agents have different regulations

5. VPS is a virtual server. Each VPS can allocate independent IP address, independent operating system, independent large space, independent memory, independent CPU resources, independent executive program and independent system configuration. As like as two peas, the VPS is a virtual server. It is built on a part of virtual resources separated from the real server. It has independent memory, hard disk and bandwidth. Independent IP. is exactly the same as the server in function and usage. Moreover, because no hardware cost is needed, the price of the same configuration is often much lower than that of the server. The cloud host is popular only in the past one or two years. Virtual machine is a kind of virtualization technology similar to VPS host. VPS uses virtual software, VZ or VM to virtualize multiple parts similar to independent host on a host. Each part can be used as a separate operating system, and the management method is the same as the host. The real cloud technology can be understood as all resources shared by all people. Therefore, the performance of real virtual machine has been greatly improved. However, there are very few enterprises providing real virtual machine and cloud server in China. Many virtual machines on the Internet are not real virtual machines in fact. The difference between
and the parent-child relationship of VPS, which is independent of a server, is that, The virtual machine is a collection of cluster host resources, which virtualizes several parts similar to independent hosts. At the same time, because many hosts in the cluster have virtual machine images, for example, the Western Digital elastic virtual machine writes four copies of data in real time, which greatly improves the security and stability of the virtual machine data. Unless all the hosts in the cluster have problems, the virtual machine will not be able to access, However, the traditional sense of VPS does not have the concept of cloud. Once the host server (parent host) fails, the virtual VPS on the server will inevitably have problems. This is one of the reasons why it is not easy for the virtual host to go down, but the VPS is easy to go down.

6. Raksmart VPS is located in the computer room of California, USA, which is very close to the domestic computer room. The server in the computer room adopts the latest software and hardware, and the service provider is a partner with China Telecom, China Unicom and China Mobile, which fully ensures the stability and domestic access speed. According to the test of many platforms, the average Ping value in China is about 180ms.

7. As like as two peas operating system and application software, they can be installed on various VPS and IP.. They are identical in function and usage. However, the principle of.VPS is different from the memory, hard disk, bandwidth, etc., which are divided by a virtualization technology on a physical server. When the physical server fails, all the VPS above will be affected and cannot be used. The virtual machine is divided into a group of cluster servers which are similar to independent hosts. Each machine in the cluster has a mirror backup of the virtual machine. When one of the machines fails, the system will automatically access other backups. Therefore, from the perspective of data security Compared with traditional VPS, virtual machine is more powerful. At present, more and more VPS have been upgraded to virtual machine

8. VPS full name virtual private server, Chinese Translation: virtual private server, is a server using virtualization technology is divided into multiple virtual, independent computers, a bit similar to your computer installed in the virtual machine, and then multiple virtual machines are distributed to different people
the full name of VPN is virtual private network, which is a kind of remote access technology. It is generally used when the external network wants to access the resources of the internal network.

9. Generally speaking, the physical machine is that you can configure a set of physical hosts by yourself, and then host them in the computer room,
while the virtual machine is a group of cluster hosts that virtualize a number of parts similar to independent hosts for users to rent, and there is no physical machine.

10. Virtual machine is a kind of original solution that a server virtualizes a lot of users for people to use. It has many problems in actual use. VPS is a kind of enhanced virtual machine. It isolates memory from users and allocates bandwidth control. It solves many problems in actual use of virtual machine, but it is still limited by many underlying technologies It can't be
implemented, such as the expansion of the real allocation of user resources used by CPU, etc.
virtual machine is a virtualization technology similar to VPS host, which virtualizes multiple parts similar to independent hosts on a group of cluster hosts, and each host in the cluster has a mirror image of the virtual machine, which greatly improves the security and stability of the virtual machine, Unless all the hosts in the cluster have problems, the virtual machine will not be able to access
