云服务器优缺点大揭秘(云服务器通俗点说是啥)

Physical Servers (PhysicalServers)

Refers to real and existing hardware-dedicated independent hosts or server equipment. The performance and stability are relatively strong, so the price is also relatively high. It is relatively expensive and requires users to configure, manage and operate it according to their needs. To put it simply, a physical server can be understood as a "computer". In fact, all website programs run on this "computer".

Cloud Servers

refers to virtualizing an independent server into multiple small servers through virtualization technology. The operation and management of each cloud server are completely independent and have A separate operating system can be assigned an independent public IP address, a large disk, operating system Windows/Linux, memory, CPU resources, etc. The website operating environment and space security need to be configured by the user themselves, which requires certain technical capabilities of the user. .

Cloud server is an important part of cloud computing services and a service platform that provides comprehensive business capabilities to all types of Internet users. The platform integrates the three core elements of Internet applications in the traditional sense: computing, storage, and network, and provides users with public Internet infrastructure services.

Physical Server VS Cloud Server

Cost Optimization

As far as physical servers are concerned, whether they are used or not, the equipment is there and the cost is still there, and it still counts. money!

Cloud servers follow the principle of purchasing on demand and paying according to usage. They have the characteristics of low cost, elastic scalability, and convenient management.

Service Optimization

Physical server services generally refer to two service types: physical server hosting and leasing. Physical server hosting is where users purchase hardware and send it to the computer room for hosting. During this period, the equipment is monitored and The management work is completed independently by the user. The IDC data center provides IP access, bandwidth access, power supply, network maintenance, etc. The leasing is when the IDC data center rents physical equipment for customers to use. It is also responsible for the stability of the environment. Users do not need to purchase it. Hardware equipment;

Cloud server service refers to a continuous and overall set of services from infrastructure (Iaas) to business basic platform (PaaS) to application layer (SaaS). IDC data center will scale The virtualized hardware servers are integrated into the cloud to provide users with service capabilities and IT efficiency.

Compared with the traditional IDC service model, the cloud computing IDC value-added service is an upgrade related to the traditional IDC value-added service. It is an upgraded version of the traditional IDC service under the cloud computing data center! In the case of cloud computing IDC, computing capabilities with high scalability and high availability can be obtained, and users no longer need to worry about problems caused by performance limitations of hardware devices.

Resource optimization

Physical server, limited integration based on hardware server, for example, multiple virtual machines share the performance of one physical server.

Cloud servers can achieve dynamic resource allocation through resource intensification, and cloud computing can achieve horizontal/vertical elastic resource expansion and rapid scheduling. The resources provided by traditional IDC cannot withstand rapid reallocation in a short period of time. Not to mention the time cost for companies to wait, which itself can easily lead to idleness and waste of resources!

As for cloud servers, the rapid reallocation of resources is achieved through updated technology. Resources can be allocated within minutes or even tens of seconds to achieve rapid availability, which can effectively avoid the risk of idle resources. In addition, traditional IDC is far inferior to cloud computing IDC, which can achieve large-scale effective integration across physical servers or even across data centers.

Efficiency Optimization

Compared with traditional IDC services, cloud computing IDC services adopt a more flexible resource utilization method and enable users to manage and maintain hardware equipment through technological improvements and optimizations. Free from work, focus on the development and innovation of internal business, and the cloud service provider is responsible for the stability of the cloud platform itself. Through this responsibility sharing model, the operating efficiency of the entire platform is improved!

After-sales optimization

First of all, cloud servers are basic telecommunications value-added services, so their service providers need to obtain approval from the Ministry of Industry and Information Technology to have corresponding operational qualifications. The cloud service provider's understanding of national policies and support for business processes such as filing also ensure that customers can operate legally and compliantly. Furthermore, when a problem occurs during the use of the server, it requires the assistance of the operator to solve it. In this case, you need to find after-sales support from the host provider at any time. Most cloud service providers will provide 7*24 hours of cloud service. Server after-sales support services can also dispel users’ worries and give them peace of mind!
