What is a cloud server? What the hell is the use

A cloud server is a simple, efficient, secure, reliable, and scalable computing service. It's simpler and more efficient to manage than a physical server. Users can quickly create or release as many ECSs as they want without purchasing hardware in advance.

Reduce DevOps effort and overall IT costs, allowing you to focus more on core business innovation.

The advantages of cloud servers are based on cloud computing technology, and compared with independent servers, they have the following characteristics:

1. From the technical aspect: cloud computing technology is used in cloud computing technology, and cloud computing technology integrates various software and hardware technologies such as computing, network, and storage. Dedicated servers, that is, independent, do not integrate these resources.

2. From the security aspect: the cloud server has natural anti-ARP attacks and MAC spoofing, snapshot backup, and data will not be lost permanently. Dedicated servers, on the other hand, don't have this feature;

3. In terms of reliability: cloud servers are based on server clusters, so the hardware redundancy is high and the failure rate is low; Dedicated servers, on the other hand, have less hardware redundancy and a higher failure rate.

4. In terms of flexibility: users can increase their own configuration in real time, and there is a large space for expansion; Dedicated servers, on the other hand, have limitations in this regard, and if you have a new application, you have to buy another one.

5. From the perspective of performance: the cloud server is 4 times the computing power of the same configuration of independent servers, which can meet the requirements of high-performance computing;

6. From the perspective of stability, cloud servers can be automatically migrated due to failures, which means that if a cloud server fails, the applications on it will be automatically migrated to other cloud servers. Dedicated servers don't have this function, and if they do, they will go down.

7. From the perspective of energy saving, the automatic migration technology of cloud servers based on cloud computing means that at night, the utilization rate of physical servers is not high, and the automatic migration technology will concentrate the application on several physical servers, and other physical servers can be dormant, so as to save energy.

1. ElasticComputeService (ECS) is a simple, efficient, secure, reliable, and scalable computing service. Its management method is simpler and more efficient than that of physical servers. Users do not need to purchase hardware in advance, and can quickly create or release any number of cloud servers.

2. Cloud servers help you quickly build more stable and secure applications, reduce the difficulty of development and operation and overall IT costs, and enable you to focus more on the innovation of your core business.

To use an image point metaphor, the previous web host is equivalent to putting a lot of single beds in this three-bedroom house, you can only rent one of the beds, and the neighbor of the next bed will snore and sleepwalk will affect you (other ** in the same room will also affect you).

Cloud serversIt is no longer a house with n rooms and halls to rent or share a house for everyone independently, but to set up different standard rooms like a hotel, all the facilities of each house are independent, and there are different sizes of room types for everyone to choose from.

In fact, the traditional server (physical host) is, to give you a computer, you have to build it yourself, pull broadband, buy memory, install the system, if you want to add memory, buy one, plug it in, if you want to change the broadband, you have to go to the operator to change.

See laughed hahaha.

When servers move from offline to public cloud, it can be understood that cloud servers, cost reduction, and better maintenance are a trend.

Cloud computing server (also known as cloud server or cloud host) is a host product in the cloud computing service system, which effectively solves the defects of difficult management and weak business scalability in traditional physical hosting and VPS services. For a specific introduction, you can take a look at the American Host Detective

Cloud Server Advantages:

More convenient to use.

Use cloud hosting storage for more aspects.

The stability of the cloud server is relatively good.

It's easier to upgrade.

More secure and reliable.

Faster response.

It has a higher cost performance.

With the rapid development of network technology, cloud servers have come into being in line with the times. The disadvantages of physical servers are gradually revealed, and the era of widespread use of cloud servers has arrived. In response to the increasing demand for data processing in the market, the IT operation and maintenance costs of enterprises are also rising sharply.

Businesses large and small are looking for safe, reliable, and cost-effective IT solutions that work for them. The digital transformation challenges of traditional enterprises are also becoming more intense, requiring more agile infrastructure. Therefore, the use of cloud servers by enterprises is not only the need for their own development, but also the inevitable development of the times.

Cloud servers can solve the pain points of small and medium-sized enterprises, cloud servers can be paid on demand, can effectively reduce comprehensive costs, isolation of hardware resources and exclusive bandwidth, centralized remote management platform can be multi-level business backup, rapid business deployment and configuration of large-scale elastic expansion capabilities.

What is a cloud server? A cloud server can also be referred to as a virtual server or a virtual private server. It is a logical server that is built, hosted, and delivered through a cloud computing platform on the internet.

Cloud servers have similar features and capabilities to typical servers but can be accessed remotely through a cloud server provider.

Purpose of cloud server:1. Place the company** and e-commerce platform.

As more and more companies start developing business channels through the internet, many companies will choose to place their ** on cloud servers and allow users to access them directly through the cloud servers. Not just businesses**, but also blogs, e-commerce platforms, and more. Not only is it safe and stable, the data is secure, but it is also cost-effective.

3. Use cloud servers to store and share data.

4. Place the game on the cloud server.

To use the metaphor of an image point, the traditional rental suit.

The server is equivalent to renting a three-bedroom house to live in by yourself; Sharing a server with others means that everyone is sharing a house (one room per person, living room and other facilities); Web hosting is the equivalent of putting a lot of single beds in this three-bedroom house, and you can only rent the beds in it. I believe that the above analogy is very easy for everyone to understand, in this environment, it is difficult to avoid being influenced and interfered by others, even the later VPS is a change of soup and not a change of medicine, but a disguised change of concept for server co-renting, and the emergence of cloud servers has completely changed the disadvantages brought by this co-renting.

The cloud server is no longer engaged in n rooms and n halls of the house to rent or share for everyone independently, but like a hotel to set up different standard rooms, all the facilities of each house are independent, there are different sizes of room types for everyone to choose, you can even use a little higher than the virtual host ** to rent a small standard room with independent facilities. To sum up the advantages of cloud servers in one sentence, it is to realize the exclusive and flexible expansion of the facilities rented by the host (you can adjust the larger standard room at any time when you have money).

In fact, the traditional server is, to give you a computer, you have to build it yourself, pull broadband, buy memory, install the system, if you want to add memory, just buy one, plug it in, if you want to change the broadband, you have to go to the operator to change.

Cloud server, because Alibaba Cloud is the leader of domestic cloud computing. Take it as an example, you can imagine that Alibaba Cloud is a very powerful computer, with super computing power, large memory distance, very fast bandwidth, and very large hard disksWhen we buy a cloud server, we choose a core, 1G memory, and 1M broadband. Ali will virtually create a one-core, 1G memory, and 1M broadband computer for you to use.

If you want to add memory to 8G, 100M broadband, just change the configuration, Ali will divide 8G memory, 100M broadband for you. All you have to do is make up the difference.

The so-called cloud server refers to a virtual server that uses software under the operating system of a physical server. This kind of server, you don't need to spend money to buy host, hard disk, CPU, memory and other hardware back to assemble yourself, it can be quickly created on the web page, it can also be very convenient to increase the number of CPUs in the later stage, improve memory, increase hard disk capacity, improve network bandwidth, etc., all this, do not need you to cut off the power like a physical machine, disassemble the chassis to increase, just 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.

The virtual server, that is, the cloud server, occupies the resources of the physical server when it runs, but it is impossible for a physical server to generate only one cloud server, and many cloud servers run on the same physical server.

In addition to the convenient improvement of configuration and performance, cloud servers also have obvious advantages: you don't need to maintain physical servers, do not occupy your own space to place physical servers, do not worry about how to deal with the eliminated physical servers, many people use the same physical server can dilute the cost, many people use the same set of network equipment (such as firewalls, routers, anti-virus walls, etc.) can also reduce the initial investment, reduce the risk of investment, in case it does not dry up one day, do not worry about what to do with those hardware devices.

In terms of use, we all know that even if the physical server is not around, it can be logged in and managed through remote tools, such as remote desktop login, and ftp tools to transfer files. Cloud servers, on the other hand, must be operated remotely because they cannot be seen or touched.

A cloud server is actually a virtual server that uses software under the operating system of a physical server. It can easily improve configuration and performance, and since it is invisible and intangible, it must be operated remotely.

Hahahaha, that's good.

Abbe Cloud provides free web hosting and free cloud server functions, official website: web link, I use it to hang QQ robots, very stable, the computing speed is about the same as the local speed, this is the method of hanging QQ robots.

How to hang cleverqq on Abbe cloud server" web link.

In fact, a cloud service can be seen as a virtual computer running on the cloud.

The cloud server is also the underlying infrastructure, and all the network sites, network software and network services are based on the cloud server, which is of course what it can do.

In terms of importance, in layman's terms, cloud servers can be regarded as as important as the current power supply.

Moreover, there are many cloud hosts, and tools are also needed to manage cloud servers, similar to cloud helpers are tools and software that specialize in managing cloud hosts.

Hope the above is helpful to you.

1. Build**.

BAI use.

Applicable to social dus

District**, enterprise zhi

Various applications such as official websites, portals**, electronic DAO business**, SaaS applications (such as on-board ERP, CRM, OA, HR, etc.), game rights, etc.

2. Office system application.

There are many types of office software, and the most widely used ones are OA, ERP, CRM, enterprise mailbox, etc.

Many programmers have their own hobby of developing apps, which can not only be used to practice, but can also be put on the shelves directly after the app matures.

4. Database application cloud service.

With the increasing scale of application deployment in the IT industry, more and more enterprises use cloud servers as separate database application servers to install database services.

5. E-commerce game platform.

**Extended Materials.

Precautions. 1. Cloud computing has certain requirements for the structural flexibility, computing density, and storage capacity of the cloud server itself. After selecting an ECS vendor, you can compare the technical specifications of specific ECS products to see whether they meet the existing and future business needs.

2. The cloud server can realize snapshot backup, and when the host fails, the cloud server can restore all the data before the failure with one click.

It's not simple, 12306 knows to copy it, and the usual amount of visits is normal, but bai is on holidays.

A hundredfold increase in the number of DU visits may cause huge fluctuations in a short period of time. But you can't buy and rent a huge server because of these days, so you can buy a cloud server, increase the number of cloud server instances when the business grows, and reduce the instances when the business declines, so as to ensure that the resource requirements when the number of visits reaches the peak, and at the same time reduce the cost. If you use load balancing, you can achieve a high-availability architecture.

Similarly, there are dividend packages from major platforms during the Spring Festival, and this kind of large traffic can instantly overwhelm the server in a short period of time.
