What is the difference between cloud computing and traditional IDC?

Cloud computing has just developed and it has developed rapidly. The competition life cycle of many traditional IDC industries is shortening. Internet unicorns with cloud computing as their core competitiveness are appearing faster and faster. So, what is the difference between cloud computing and traditional IDC? What are the characteristics of cloud computing and traditional IDC?

1. The difference between cloud computing and traditional IDC in service types

Commonly used traditional IDC services include entity server hosting and lease.

The former is purchased by the user and sent to the computer room for hosting. During the monitoring and management of the equipment, the equipment is independently completed by the user. The IDC data center provides IP access, bandwidth access, power supply and network maintenance. The latter is IDC. The data center rents physical devices for use by customers, and is responsible for the stability of the environment. Users do not need to purchase hardware devices.

The cloud computing service is a continuous whole package from the infrastructure (Iaas) to the business infrastructure platform (PaaS) to the application layer (SaaS).

The IDC data center consolidates the scaled hardware servers into the cloud, providing users with service capabilities and IT performance. Users do not have to worry about the performance limitations of any hardware device, and can get high scalability and high availability computing power.

2. The difference between cloud computing and traditional IDC in terms of resource intensification speed and scale

In the final analysis, cloud computing is a dynamic resource allocation through resource intensification. Traditional IDC services can also achieve simple intensification, but the two are very different in terms of resource integration speed and scale. Traditional IDCs only have limited integration on the basis of hardware servers, such as multiple virtual machines sharing a single physical server performance. However, this simple intensification is limited by the resource size of a single physical server, far less than the physical integration of cloud computing, or even large-scale effective integration across data centers.

More importantly, the resources provided by traditional IDCs are difficult to withstand rapid redistribution in a short period of time.

3. The difference between cloud computing and traditional IDC in resource allocation time lag

It is well known that due to the deployment and configuration of physical hardware, the delivery of traditional IDC resources usually takes hours or even days, which will increase the time cost of the enterprise, and more energy consumption, and it is difficult to real-time and rapid resource redistribution. And easily cause resources to be idle and wasted.

In cloud computing, resources can be quickly redistributed through updated technologies, resources can be allocated quickly in minutes or even tens of seconds, and the huge resource size in the cloud virtual resource pool enables rapid redistribution of massive resources. And to effectively avoid the risk of resource idle.

4. The difference between cloud computing and traditional IDC in platform operation efficiency

More flexible resource application methods and higher technology enhancements enable cloud service providers to have a collection of advantages and innovative resource utilization methods to promote the efficiency of the entire platform. Moreover, unlike traditional IDC services, cloud computing frees users 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 model improves the operational efficiency of the entire platform.

Simply put, cloud computing is an extension and development of traditional IDC services. Cloud computing is to connect multiple computing nodes into a large virtual resource pool to improve computing efficiency, so that the efficiency and scale of resource redistribution are not limited to a single physical server or even a single IDC data center. Regardless of the delivery/service approach, the size of resource allocation, the speed of resource allocation, or the operational efficiency of the entire platform, cloud computing has greatly improved compared to traditional IDC services. This upgrade will be created for enterprises and developers in various industries. Higher value.

5. Can traditional IDC hold it?

In the past, the traditional servers used to install a virtual host software to sell space, there is no market, and the slightly larger traditional IDC has also been upgraded to vps, but from the current point of view, the popularity is very general. And the price is expensive, and the customer development cost is high. On the other hand, due to the trouble of filing, large and medium-sized webmasters and blog sites have turned to idc enterprises in the US or overseas. Several foreign idcs have basically realized virtualization and basic cloud computing, and the price is extremely low.

The survival of traditional small IDCs will be even more difficult. If Sina, Shanda, and Alibaba Cloud computing products get through the filing channel, then a large number of customers who originally belonged to IDC will transfer to cloud computing companies at a high speed, and this is almost unstoppable. In addition to server hosting, the larger idc merchants in China will also suffer the most severe impact on their virtual hosting business. In addition, several major manufacturers of cloud computing are well-known enterprises, and consumers trust them much more than idc vendors.

6. Small thinking on the transformation of IDC industry chain

No transformation is not good, small idc business should give up the strategy, choose the mode of deep cooperation with open source software, the original model has been going through more than ten years, and the cloud computing products are basically mature. At this time, the focus is more than the big net. effective. At the same time, the author believes that idc can be transformed into a cloud computing application provider, integrated into the new cloud computing industry chain, rather than external confrontation.

Shanda Cloud Hosting and Alibaba Cloud Hosting are now basically mature. As long as they make the user's tutorials and interface design more reasonable, they will soon explode, even if it is a business like Wanwang. At the same time, the Internet is becoming more and more social, and the number of professional webmasters is becoming less and less. The number of products that drive idc development like blogs will be less and less. When online marketing is more and more inclined to social platforms, the demand for independent websites will be Will be relatively weak.
