How about the cloud server ah How about the cloud server

Hello landlord, if it is an enterprise that chooses a server, it depends on what aspect of the business it is doing. If it is an enterprise, the general requirements for host configuration are not high, even a few hundred trillion virtual hosts can be satisfied, if the overall security requirements are higher, you can also choose cloud hosts, or independent servers. If you want to place other types of services in the enterprise, you can select a suitable host based on the requirements of the business for machine hardware and bandwidth.

In fact, the birth of cloud hosting has gradually developed from the server, and its use has also done a lot of technical challenges, so cloud hosting is so popular with enterprises. The domestic service is provided by the cloud, Yimai cloud, Alibaba cloud, Tencent cloud, etc. for enterprises to choose, the large factory is expensive, and the small factory is higher in price reduction.

Virtual machines (cloud servers).

Concept: A cloud server is a simple, efficient, secure, reliable, and elastically scalable computing service, which allows users to quickly create or release any number of cloud servers without purchasing them in advance. This kind of server, do not need to spend money to buy host, hard disk, CPU, memory and other hardware back to assemble by yourself, it can be quickly created on the web page, can also be very convenient in the later stage to increase the number of CPUs, improve memory, increase hard disk capacity, improve network bandwidth, etc., all this, do not need you to power off like a physical machine, disassemble the chassis to increase, only need to suspend the operation of the server, and then click the mouse on the background management of the web page can be completed, Don't worry about the compatibility of the new hardware, because everything is virtual.

Features of cloud servers:1. Elastic expansion, configurable upgrade, pay-as-you-go.

2. Simple and efficient, no need to purchase machines in advance, ready to use, rapid business deployment.

3. Independent operating system, isolation of hardware resources + exclusive bandwidth.

4. Centralized remote management platform + multi-level business backup.

Advantages and disadvantages of cloud servers1. Advantages. Independent IP, independent bandwidth, server speed, independent IP can better ensure the security of the world. At the same time, the cloud server also has an image function to avoid the loss of server data, which further guarantees the best security.

2. Disadvantages. The cost is lower than that of a traditional server, but higher than that of web hosting. The environment configuration of the server needs to be built by yourself, and there must be a certain degree of professionalism.

It is the best choice for small enterprises to choose cloud servers for building websites I have cloud server resources at home and abroad.

Cloud server rental** is lower than traditional physical server rental, and no deposit is required, with fast ** and deployment capabilities, users can be opened in real time after submitting the cloud host lease application, immediately get services, business support smooth expansion, when the user's business scale expands, business expansion can be quickly realized.

1. Cloud server is suitable for users who pay attention to the cost-effective hosting service; Users who need to quickly implement distributed deployment; Users who need the ability to expand their business elastically; Users who have the need for high availability and fast recovery of the system; Users who want to manage their systems with ease. Support e-commerce, forums, SNS, enterprises, OA systems and other Internet applications.

2. Cloud server users can easily carry out remote maintenance, and realize complete isolation between cloud hosts at the hardware level of free reinstallation system; Built-in redundant shared storage and intelligent backups, physical server failures can be automatically recovered within minutes; The service environment is deployed with high-end servers, and centralized management and monitoring are used to ensure business stability and reliability. Stronger host performance, the overall performance is much higher than VPS, and stronger than some dedicated servers.

3. The cloud server will be equipped with different IP addresses according to the user's choice of different lines. By default, a single line will give one independent IP address, and two independent IPs will be given to two lines. If the bandwidth cannot be limited due to the increase in IP address, the IP address will not be increased temporarily.

4. The cloud server is a host product based on the cloud computing platform, and the user actually pays for the computing and storage capacity and high-quality network bandwidth of the cloud computing platform. Users only need to pay for the resources they actually use, which is also a major factor that users can significantly reduce costs by choosing cloud hosts.

Compared with traditional servers, cloud computing servers have their distinctive characteristics: high density, high scalability, and powerful virtualization capabilities.

High density

If "cloud computing" is the trend of the times, then high-density servers are imperative: high-density multi-node servers that integrate 2, 4, or even 8 independent computing nodes in a 2U space have become the focus of today's IT infrastructure.

Improving energy efficiency, reducing footprint, and reducing power consumption are the major advantages of high-density servers. At present, high-density servers are mainly divided into multi-socket racks and blades. Cloud computing also has different requirements for data center performance and efficiency, with some operations requiring more compute, and high-density servers reducing latency and improving responsiveness.

Internet games and other areas have begun to try cloud computing, and they perform even better with high-density servers.

High scalability

Server scalability means that the hardware configuration of the server can be flexibly configured according to needs, such as memory, adapters, hard disks, processors, etc., because the hardware configuration of the server may change according to the network configuration in different periods.

One of the essential characteristics of cloud computing is to help enterprise users realize on-demand, flexible and efficient use of IT resources. Therefore, for the deployment of cloud computing platforms, it is necessary to consider the real need for elastic space and scalability. At present, whether in terms of servers or storage, the existing product architecture of many enterprises cannot have good scalability, which can well meet the elastic needs of private clouds for expansion space.

Therefore, a realistic assessment of resiliency requirements is an important consideration before implementing a private cloud deployment that adds or decreases IT resources as needed.

Powerful virtualization capabilities

Virtualization enables the logical abstraction and unified representation of IT resources, plays a huge role in large-scale data center management and solution delivery, and is an important technical cornerstone to support the grand vision of cloud computing.

Cloud computing inevitably requires the use of server virtualization technology, so the virtualization capability of the server has become an important reference index when selecting a model. This requires the server to have good performance, sufficient memory, platform support, and provisioning efficiency.

There are many advantages to cloud servers, including:

Higher availability: Cloud servers can provide high availability because they can provide services on multiple servers and are smart and can be dynamically adjusted as needed.

Higher scalability: Cloud servers can provide greater scalability as they can be dynamically adjusted as needed to meet changing needs.

Lower cost: The cost of cloud servers is relatively low, because they use on-demand fees, which are lower cost and more scalable than traditional self-built independent servers.

Higher security: Cloud servers can provide more security as they can provide security measures such as firewalls, intrusion detection, etc.

Higher reliability: Cloud servers can provide higher reliability because they can provide services such as backup and recovery to ensure the availability of the server.

In conclusion, the great thing about cloud servers is that they can provide higher availability, scalability, cost, security, and reliability.
