Why does cloud computing have an overwhelming advantage over traditional technologies in terms of cost performance?

Cloud server is an important part of cloud computing service, and it is a service platform that provides comprehensive business capabilities for all kinds of Internet users. The platform integrates the three core elements of traditional Internet applications: computing, storage and network, and provides users with public Internet infrastructure services. Cloud server service includes two core products: cloud server rental service for small and medium-sized enterprises and high-end users; Flexible computing platform services for large and medium-sized Internet users. Each cluster node of the cloud server platform is deployed in the backbone data center of the Internet and can independently provide Internet infrastructure services such as computing, storage, online backup, hosting and bandwidth. A cluster node consists of the following hardware: Management server: manages all computing servers, storage and networks of the whole node in a hot standby mode, and provides an API for managing the whole node. The management server provides: management service (management node's computing server, providing external management interface), DHCP service (allocating IP of management network segment for computing server's network startup), tftp service (providing remote startup image for computing server's network startup) and nbd service (providing network block equipment service for computing server). A data acquisition program will also run on the management server, which will regularly collect various performance data and send them to the central data acquisition server. The storage server can be an ISCSI or x86 server with built-in large storage capacity, which forms a unified storage pool through clustered file systems, and provides logical disk storage, unstructured data storage and integrated backup services for virtual machines in nodes. Computing server group: The computing server is a high-configuration server above eight nuclear, and it does not need to install an operating system, but it must have the network boot function, run a linux microkernel, cloud computer software and a proxy switch, and communicate with the management server: according to different functions and node performance requirements, it is equipped with multiple three-layer switches. The service advantage of cloud server, the cloud server is responsible for managing network segments, public switching network segments, internal switching network segments, storage network segments, etc. Cloud computing server (also known as cloud server or cloud host) mainly provides Internet-based infrastructure services for small and medium-sized enterprise users and high-end users. This user group is huge, and the demand for Internet host applications is increasing. The user group has the following characteristics: the business is mainly host rental and virtual private service, and some of them use hosting services, which is large in scale; Pay attention to short-term return on investment, and have high cost performance requirements for products; Personalized demand is strong, and it tends to be full value chain and fool-like products. When users use traditional servers, they have to face various thorny problems due to many factors such as cost and operator selection, and the introduction of elastic cloud computing servers effectively solves this problem. Please refer to the following table: 1. What is a cloud server? Cloud computing server (also called 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 expansion in traditional physical leasing and VPS services. In practical application, cloud hosting has three aspects of flexibility: host service configuration and business scale can be configured according to user needs and can be flexibly adjusted. The host service applied by users can be quickly supplied and deployed (real-time online opening), and flexible and scalable charging methods in the cluster can be realized. Users do not need to pay a deposit, and there are many payment methods for users to choose from. 2. What kind of users is the cloud server suitable for? Users who pay attention to the cost performance of host service; Users who need to quickly realize distributed deployment; Users who need flexible business expansion; Users with high system availability and quick recovery requirements; Users who want to manage the system easily. Support Internet applications such as e-commerce, forums, SNS, corporate websites and OA systems; Illegal applications such as private servers, pornography and plug-ins are prohibited. Once found, close it immediately, no refund! 3. What are the main advantages of cloud server compared with VPS? Users can conveniently carry out remote maintenance and reinstall the system for free, so as to realize complete isolation between cloud hosts at the hardware level; Built-in redundant * * * shared storage and intelligent backup, physical server failure can be automatically recovered within a few minutes; High-end servers are deployed in the service environment, and centralized management and monitoring are adopted to ensure stable and reliable business. Host performance is stronger, the overall performance is much higher than VPS, stronger than some independent servers; 4. What are the main advantages of cloud servers compared with renting physical servers? The rental price of cloud server is lower than that of traditional physical server, and there is no need to pay a deposit. With the ability of rapid provisioning and deployment, users can open it in real time and get services immediately after submitting the application for cloud hosting lease. Business supports smooth expansion, and when the business scale of users expands, business expansion can be realized quickly. 5. Can the cloud server apply for multiple IPS? The cloud server will be equipped with different numbers of IP addresses according to different lines selected by users. By default, a single line will have one independent ip, and a double line will have two independent IPS. Due to the increase of IP, the bandwidth cannot be limited, so IP is not increased for the time being. 6. Do cloud server rental products deliver property rights? Do not send property rights. Cloud server is a host product based on cloud computing platform, and users actually pay for the computing, storage capacity and high-quality network bandwidth of cloud computing platform. Users only need to pay for the resources actually used, which is also a major factor that users can greatly reduce the cost by choosing a cloud host. 7. Can users choose to install the operating system? Of course. There is no obvious difference between the cloud host and the traditional physical server in the form of product use, and users can flexibly choose or change the operating system according to their own needs. 8. How long will it take if I want to buy it? How long will it take to expand? Registered users-> Online payment-> Buy a cloud server and open it in real time. Log in to the user management area after opening it-> Cloud server management->; Management->; Pre-installed operating system, you can choose Windows2003, windows2008, CentOS5.6 and other operating systems. The system installation takes 10-25 minutes. After the system is installed, you can perform other application operations through remote connection. 9. Do I need to pay a deposit to rent a cloud server? Different from traditional physical server leasing, cloud server leasing users can enjoy services without paying a deposit. 10. How to view the configuration of the rented host? Because the cloud server is equivalent to the physical server in use, users can view the configuration information and current resource usage of the server in real time in the operating system. 1 1. Can the backup disk be used to store my files? The backup disk is used for intelligent backup service of the system, mainly for disaster recovery. 12. How many CPUs are there in the Task Manager? After installing the operating system, you must restart the cloud server to see multiple CPUs, unless you only bought one CPU.
