Will cloud servers make traditional servers obsolete

It's hard to say for a long time, but not in a short time, after all, some of the advantages of traditional physical servers cannot be replaced by cloud hosts. For example, traditional servers with high configuration can use dual Xeon processors with 128G memory, while cloud servers are divided into many cluster systems, and the maximum memory of ordinary servers does not exceed 16GFor example, a physical server may support the expansion of 4 to 8 hard disks in a chassis, which can greatly expand the capacity and make disk arrays, while cloud servers do not have such great scalability.

It is impossible for cloud servers to eliminate traditional servers, do you know what a cloud server is? It is to divide the configuration of traditional servers, such as: memory, disk, core (CPU), and bandwidth, into Nuogan cloud servers according to different needs, that is to say, cloud servers are built on the basis of traditional servers, and the same is true for cloud web hosting, so it is impossible for cloud servers to eliminate traditional servers, and even say:

Because it is necessary to meet the needs of cloud servers so that traditional servers can survive.

The above said that the cloud server does not have so much scalability, I don't think so, elastic cloud or something, you can understand, like cloud server upgrade configuration or something, now most service providers can meet this requirement (in the case of purchase and use, non-interrupted upgrade configuration, can even more perfectly meet the requirements of pay-as-you-go), 64 core cup, 256G memory, 100T disk, 100M bandwidth, these are not a problem at all, and can meet higher requirements in the future.

And these are built on the foundation of traditional servers, which means that this also accelerates the development and progress of traditional servers.

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.

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

The traditional server is with independent CPU, memory module, hard disk, the stored data security is not high, the waste rate of hard disk is relatively high, the application has limitations, if there is a new application, then you can only buy another one, which causes a serious waste of server, for some small and medium-sized enterprises can not be underestimated.

In the end, who is superior and who is inferior can be analyzed through the following points:

1. From the technical aspect, the manuscript is suspicious.

Cloud servers use cloud computing technology, which integrates various software and hardware technologies such as computing, networking, and storage. Traditional servers, which are independent, do not integrate these resources.

2. From the perspective of security.

The cloud server has natural anti-ARP attacks and MAC spoofing, snapshot backup, and data is never lost. Traditional servers 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. Traditional servers, on the other hand, have less hardware redundancy and a higher failure rate.

4. In terms of flexibility.

5. From a performance point of view.

The ECS is four times the computing power of an independent server with the same configuration, which can meet the requirements of high-performance computing.

6. From the perspective of stability.

ECSs can be automatically migrated if they fail, which means that if an ECS fails, the applications on it are automatically migrated to other ECSs. Traditional servers don't have this function, and if they are broken, they will be broken.

The key is quietly handed, and the cloud server is relatively better.

1. At the level of hardware Huai Youyou equipment.

Local server: server host, storage, network equipment, power supply, etc.; Cloud servers, cloud servers, such as virtual grinder hosts, containers, bare metal, etc.

2. At the level of software system.

Local servers: operating systems, database systems, application servers, web servers, etc. Cloud servers, virtualization technology, network topology technology, application orchestration technology, container technology, etc.

3. At the level of network architecture.

Local service lead: network topology, device configuration parameter settings, route configuration, etc.; ECSs, which can be configured based on business needs, such as ECSs, load balancing, and auto scaling.

4. In. Security policy level.

Local server, security rule design, data backup, risk assessment, etc.; Data segmentation, multiple backups, data encryption, etc.

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.

Let's start with traditional dedicated servers. It is an independent hardware device, which can be understood as a high-configuration computer placed in the computer room with an independent processor. Memory, hard disk, bandwidth and other resources, you can install various operating systems and configure various environments according to your needs, and the performance is also relatively powerful.

Cloud server, also called cloud host, is the use of virtual technology on a group of cluster servers divided into a plurality of independent host-like parts, each machine in the cluster has a cloud host image backup, when one of the machines has a problem, the other machines on the mirror can also be accessed normally.

Therefore, compared with traditional servers, cloud hosts are better in terms of data security and stability, but cloud hosts usually have less configuration and bandwidth than servers. Generally suitable for small and medium-sized ** or applications. And the server performance is powerful.

Suitable for larger scales** or applications.

When there is more demand on the server, the capacity can be automatically increased to meet the demand without paying permanently, while the physical server needs to configure various parameters, if the demand is underestimated, it can lead to a lack of necessary resources during busy periods, and overestimating will mean paying unnecessary expenses.

Generally speaking, a private cloud server to the power of 10 can be flexibly upgraded according to your own needs, while a physical machine cannot do this. Cloud servers offer more redundancy, and if one server fails, others will quickly replace it, avoiding losses to customers, something that physical servers simply don't have.

Normal server: A server refers to a computer software that manages resources and provides services to users, which is usually divided into file servers, database servers, and application servers. The computer or computer system running the above software is also known as a server.

It's a physical machine.

Elastic Compute Service (ECS) is a basic cloud computing service provided by Alibaba Cloud.

Using ECS is as convenient and efficient as using resources such as water, electricity, and gas. You do not need to purchase hardware devices in advance, but you can create as many ECS instances as you need at any time based on your business needs. As your business expands, you can expand the disk capacity and increase the bandwidth at any time.

If you no longer need a cloud server, you can release resources at any time to save costs.

All resources involved in ECS, including instance types, block storage, images, snapshots, bandwidth, and security groups. You can configure your ECS resources through the CVM console or the Alibaba Cloud app.

What are the main advantages of cloud servers over regular physical servers? Cloud server rental** is lower than traditional physical server rental, and no deposit is required. With fast ** and deployment capabilities, users can open it in real time after submitting the cloud host rental application, and get the service immediately.

The service supports smooth scaling, and when the user's business scale expands, the service can be quickly expanded!!

Renting a cloud server can avoid outdated equipment and obsolescence losses in the later stage.
