What is the difference between a cloud server and a traditional server?

If VPS is like a faucet, the computing and storage resources of a server are a water pipe with many faucets on it. You will need to pay to rent this faucet, and its water flow is limited. If you want to get a bigger flow of water, then you need to rent more taps, and at the same time, if all the taps are running water, then the water flow rate of each tap will be reduced.

Under the cloud computing, what you get is a faucet with large or small traffic, and the server becomes a group from one to a group, just like a water pipe becomes a large water pipe composed of many water pipes. When you need a bigger flow of water, you can directly control your faucet to increase the flow of water, and even if all the pipes are flowing, it will not affect your water flow. What's more, the cost you have to pay is no longer the cost of renting a water pipe, but the amount of water you need.

As for setting up or renting the entire server yourself, at the moment it seems that the economy is much worse, because you have to buy even the faucets and pipes, and when you don't have enough of them, you have to buy them again. We all know that the server resource usage rate is usually 20%, unless the business is very stable, will not grow significantly, or is particularly not bad for money, you can consider building your own. Although we know the difference between cloud host and VPS, how to choose cloud host has become a problem, it can be said that this market is mixed, and even the cloud host sold is actually a VPS.

So we have to focus on two main points, first.

First, what is the quality of this big water pipe, that is, the quality of the data center on which it is based. Clause.

Second, whether the connection between the large water pipe and each faucet is effective, and whether the flow volume and stability of the faucet can be guaranteed. There are many ways to measure the quality of a data center, but in fact, the easiest way is to look at the customers in the computer room. If the main customer of a data center is a private server, do you say okay As for the connection of large water pipes, virtualization technology should be considered mainly (the network is also the key, but the network has become secondary in the context of cloud computing), and many cloud host applications cannot be run, or are prone to problems, which mainly stem from virtualization technology.

This technology can be said to be still in the development period, relatively mature and leading, it should be said that VMware is second to none, and domestic Alibaba Cloud, Shanda Cloud and other products are also catching up at a high speed, with mixed reviews, you can take a look at the online reviews yourself. On the whole, if you want a better cloud computing IaaS, you still have to weigh your requirements for this cloud host. <>

The server itself does not have the concept of "cloud", because the industry does not have a unified understanding of "cloud computing", and there is no way to call a certain type of server a "cloud server". The "cloud server" claimed by the equipment manufacturer is nothing more than the belief that this type of server is more suitable for a certain type of (note, only a certain type) of cloud computing services. If there is one characteristic that must be summarized for servers suitable for cloud computing services, it is "high efficiency and low cost".

In order to achieve this goal, the server needs to do the following optimization work: unnecessary parts can be eliminated and costs can be reduced. For example, optical drives, or even chassis; The server configuration can match the business as much as possible, for example, for web servers and storage servers, the CPU, memory, hard disk and other configurations should be different; Hardware acceleration capabilities for virtualization (if used for virtualization); <

What cannot be configured independently is definitely not a real cloud server (cloud server). The virtual machine has the function of self-configuration, that is, the user can independently configure the parameters of the host, and the parameters of the virtual host cannot be changed by the user at will. If you can modify the configuration parameters of the host independently when you choose to buy, then it is easy and stress-free to upgrade the system or reinstall the system of the real cloud host.

The virtual machine can upgrade the system or reinstall the system. Buying a cloud host is equivalent to buying a server for the host, you can have full server root access, and you can upgrade and reinstall the system. For virtual hosts, there is no root access, and it is impossible to reinstall the operating system.

Automatically back up data in real-time, no manual operation required. This is one of the important manifestations of cloud host security. Virtual machines belong to distributed cluster storage, which can realize real-time backup of data, no need for manual, and no risk of data loss.

However, web hosting does not have this feature, and can only be backed up manually, which will be less secure. Separate IP and do not share with others. Each virtual machine corresponds to a completely independent IP and is not shared with others.

Virtual hosts are almost all public IPs, and virtual hosts are non-allocated spaces on a server, and a common space shares an IP. If you are buying cloud hosting, and your IP is indeed shared with others, then you may be deceived by the ** business<>

There are three main differences between cloud servers and ordinary servers:

1. Different definitions:

A cloud server is a simple, efficient, secure, reliable, and scalable computing service with scalable processing power.

An ordinary server is a server with a relatively fixed location, which is a hardware device that provides computing services.

2. Different configurations:

ECSs can quickly create or release any number of ECSs without purchasing hardware in advance, and all computing is implemented in the cloud, reducing the difficulty of development and operation and overall IT costs.

The composition of an ordinary server includes a processor, hard disk, memory, system bus, etc., which is similar to a general computer architecture, and the cost is high.

3. The failure rate is different

ECSs are cluster-based, so the hardware redundancy is high and the failure rate is low.

Physical machines, on the other hand, have less hardware redundancy and a higher failure rate.

1. High flexibility.

The hardware configuration of the ECS can be flexibly configured and expanded according to your needs (network configuration in different periods), such as CPU, memory, and SSD data disks.

2. High performance.

The cloud service environment is deployed with high-end servers and centralized management and monitoring to ensure business stability and reliability. Stronger host performance, the overall performance is much higher than VPS, and stronger than some dedicated servers.

3. Convenience.

For some small and medium-sized enterprises, with the continuous expansion of business, it may be necessary to expand and upgrade operations in the later stage.

4. Network security.

The server is most afraid of failure, the operation of the first will not be able to carry out normally, cloud products generally do not appear in this situation, even if there is a problem in the operation of the first machine, it will be automatically transferred to other machines, and it will be very difficult for hackers to attack.

5. Low cost.

Cloud server rental supports monthly and annual payment, flexible billing methods, no deposit, on-demand elastic expansion, only need to pay for the storage capacity, computing power and resources used, buy as much as you need, and will not cause waste of resources. For more comparisons, see: Web Links.

Cloud server is VPS virtualization technology, generally a server, can virtualize multiple similar servers, each part has a separate operating system, the management method is the same.

In the case of servers, the advantage is that it has independent use rights, independent bandwidth, independent hard disks, and all independent hardware. Not influenced by others.

The Elite server will answer for you.

Difference Between Cloud Server and Traditional Server:

1. The cloud server is virtual; Traditional servers are real physical devices.

2. The cloud server has the function of automatic data synchronization and backup by default; Traditional servers need to add hard disks for RAID to achieve automatic backup.

3. The configuration and bandwidth of cloud servers are usually relatively low; Traditional servers have high configuration and sufficient bandwidth.

4. Cost: Cloud servers save hardware costs and are relatively cheap; Traditional servers are comparatively more expensive.

6. Technology: The cloud server is based on cloud computing technology, integrating various software and hardware technologies such as computing, network, and storage. Physical machines, on the other hand, will not integrate these resources;

7. Safety:Cloud serversWith natural anti-ARP attack and MAC spoofing, snapshot backup, data will not be lost forever. For example, Xunyun server is divided into cache, precipitation, and backup layers, and the three layers are used for data processing, caching, and disaster recovery, and real-time synchronization between the three layers achieves data security and high availability.

Physical machines, on the other hand, do not have this function;

8. Reliability: Cloud servers are based on server clusters, so the hardware redundancy is high and the failure rate is low; Physical machines, on the other hand, have less hardware redundancy and a higher failure rate.

10. Performance: The cloud server realizes complete isolation between cloud hosts at the hardware level; High-end servers are used for deployment, and centralized management and monitoring are used to ensure business stability and reliability.

11. Stability: ECSs can be automatically migrated due to failures, which means that if a CVM fails, the applications on it will be automatically migrated to other ECSs. A physical machine that goes down is down and cannot be saved.

The cloud service allows users to pass through.

The Internet stores and reads dataBy breeding a large number of startup DAO company editions, it provides a wealth of personalized products to meet the expanding personalized needs of the market. Its breeding method is to provide startups with a complete set of services such as capital, promotion, payment, logistics, and customer service, and let their own operational capabilities be used externally on demand like water and electricity.

This is the business model of cloud services.

Elastic Compute Service (ECS) is a simple, efficient, and scalable computing service that helps you quickly build more stable and secure applications, improve O&M efficiency, reduce IT costs, and enable you to focus more on core business innovation.

At present, EMAI cloud servers are available in South China, North China, Southwest China, Central China, Hong Kong, the United States and other regions, fully meeting the business needs of users in different networks and regions such as China Telecom, China Unicom, and Mobile. Provide fast, stable and secure cloud computing products, as well as enterprise private cloud and hybrid cloud solutions.

Users can freely choose CPU, memory, data disk, bandwidth and other configurations according to the different needs of cloud hosts, and can also upgrade bandwidth at any time without stopping and upgrading CPU and memory within 1 minute, supporting the sustainable development of business. High availability ensures the stable operation of the business.

1. Traditional servers have property rights, while cloud hosts.

DU is just a service, and zhi does not have any property rights; dao

2. The traditional internal server is an independent capacity server, and all functions are completed by themselves, while the cloud host is a cluster, and their functions need to be assisted by each other to complete;

3. Traditional servers are more stable in performance, while cloud hosts are relatively worse than traditional servers in terms of performance;

4. The traditional server is very mature in China, and no one has mastered the real technology of cloud hosts in China, so many so-called cloud hosts in the domestic market are fake;

5. Compared with traditional servers, cloud hosts are more cost-effective;

6. The cloud host is purchased on demand, and the cost control is more flexible;

7. Compared with traditional servers, cloud hosts are more efficient, but less stable than traditional servers;

Cloud hosting customers are generally concentrated in small enterprises and mobile game industries that do not have high requirements for network stability and host performance, while large and medium-sized enterprises generally have high requirements for network stability and host performance, so they will choose traditional servers. The American Host Detective provides more cloud server-related consultations.

1. Fee input.

Traditional servers cost more BAI, so.

Hosting, renting, or hosting

The difference is nothing more than a few points: functionality, cost performance, difficulty to get started, and security. Specifically, depending on your needs, choose the right one for you.

Hahahaha, that's good.

ECS BAI has the following advantages:

1.Agile: Deploy a cloud server, the slowest Tencent DAO cloud is only within 10 minutes, but what if you use a physical server, procurement? Put it in the computer room, you must know that time is the biggest cost.

2.Flexible scaling: Everyone who has been an architect must know that estimating usage is a very unreliable thing, and if you use a physical server, the usage is estimated to be too much, which is a waste of money; The estimate is less, not enough, **slow, scolded to death by the leader.

However, in the case of cloud servers, you can easily expand and use as much as you want, without estimating the amount in advance.

3.O&M: What are the most expensive resources today? It is talent, and labor cost is an expense that cannot be ignored for every enterprise, and the use of cloud host can greatly reduce the labor cost of operation and maintenance.

4.Reliability: If there is a problem with the physical server, repair it yourself, and migrate the cloud server directly, a matter of minutes.
