What is the difference between cloud computing and traditional IDC?
Cloud computing has just landed in the rapid development of many traditional IDC industries. The life cycle of competition is shortening, and cloud computing, as the core competitiveness of Internet unicorn, appears more and more quickly. What's the difference between cloud computing and traditional IDC? What are the characteristics of cloud computing and traditional IDC?
1. Differences in service types between cloud computing and traditional IDC
Common traditional IDC services include physical server hosting and leasing.
The former is that the user purchases hardware from the computer room host, which is independently completed by the user in the equipment monitoring management, IDC data center provides IP access, bandwidth access, power supply and network maintenance. IDC data center leases physical equipment from customers to be responsible for the stability of the environment. Users do not need to purchase hardware equipment.
Cloud computing provides services from infrastructure (Iaas) to business infrastructure platform (PaaS) to application layer (SaaS).
IDC data center extends hardware server integration virtualization to the cloud to provide users with service functions and IT performance. Users need not worry about the performance limitations of any hardware device to obtain highly scalable and available computing power.
2. The difference between cloud computing and traditional IDC in resource intensive speed and scale
In the final analysis, cloud computing is the dynamic configuration of resources through resource intensive. Traditional IDC services can also be simple and intensive, but they are completely different in terms of integration speed and resource scale. Traditional IDC has limited integration only on the basis of hardware servers. For example, multiple virtual machines share the performance of physical servers. However, this simple and intensive type is limited by the size of a single physical server resource, which is far lower than cloud computing as a cross entity server, and even large-scale effective integration across data centers.
More importantly, it is difficult to reallocate the resources provided by traditional IDC in a short time.
3. The difference between cloud computing and traditional IDC in resource configuration
As we all know, due to the deployment and configuration of physical hardware, the delivery of traditional IDC resources usually takes several hours or even days, which will increase the time cost of the business and more energy consumption. It is difficult to achieve real-time and rapid resource reallocation, which easily leads to idle and waste of resources.
Cloud computing realizes rapid resource reallocation through updating technology. Resource allocation can be provided quickly in a few minutes or even tens of seconds. A large number of resources in the cloud virtual resource pool can withstand rapid reallocation of a large number of resources, effectively avoiding the risk of idle resources.
4. The difference between cloud computing and traditional IDC in operational efficiency on the platform
More flexible application resources and higher technology can improve the collection and innovation resources of cloud service providers, so as to improve the efficiency of the entire platform and improve the operational efficiency. Unlike traditional IDC services, cloud computing allows users to stand out from the management and operation of hardware devices. Focusing on the development and innovation of internal services, cloud service providers are responsible for the stability of the cloud platform itself. This responsibility sharing mode improves the efficiency of the entire platform.
In short, cloud computing is the extension and development of traditional IDC services. Cloud computing connects multiple computing nodes to a large virtual resource pool to improve computing efficiency, so that the efficiency and scale of resource reallocation are not limited to a single physical server, or even a single IDC data center. In terms of delivery/service, resource allocation, resource allocation or the efficiency of the entire platform, cloud computing has been greatly upgraded compared with traditional IDC services. This upgrade will create higher value for industry enterprises and developers.
5. Can traditional IDC hold it?
In the past, traditional servers installed virtual host software to sell and play. There was no market more and more, and larger traditional IDCs began to upgrade to vps. At present, The popularity of vps is general and expensive, and the cost of customer development is high. On the other hand, due to the trouble of recording, a large number of long-time blogs and blog websites have been sent to IDC enterprises in the United States or overseas. Several IDCs from foreign countries have basically realized virtualization and basic cloud computing, and the price is very low.
The survival of traditional small IDC will be more difficult. If Sina, Shanda and Alibaba Cloud computing products create a record channel, then inevitably a large number of customers will be transferred from IDC to cloud computing providers at a high speed, which is almost unstoppable. In addition to server hosting, the virtual host business will also be most seriously affected by a large number of domestic idc businesses. In addition, several major cloud computing manufacturers are well-known enterprises, and consumers trust them far more than idc businesses.
6， IDC industry chain transformation small thinking
It's not good to have no transition. I think the small idc business strategy will give up and choose the deep cooperation with the open source software binding mode. The original mode has gone through more than ten years, and the cloud computing products are basically mature. This time, the focus is more efficient than pulling the net. At the same time, I believe that the idc business can be transformed into a cloud computing application provider and enter a new cloud computing industry chain, rather than an external confrontation.
Large cloud hosts and Alibaba Cloud hosts are now basically mature. As long as they use more reasonable user tutorials and interface design, they are about to usher in explosive development, even enterprises in the world are anxious. At the same time, there are more and more professional social networking website administrator teams on the Internet, and there will be less and less promoting the development of idc products like blogs. When online marketing is more and more inclined to social platforms, the demand for independent websites will be relatively weak.
