What is the difference between cloud computing and traditional IDC? What are the characteristics of cloud computing and traditional IDC?

Cloud computing has just landed and achieved rapid development. The competition life cycle of many traditional IDC industries is shortening, and Internet unicorns with cloud computing as the core competitiveness are emerging more and more quickly. 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 physical server hosting and leasing.

The former is that users buy their own hardware and send it to the computer room for hosting. During this period, the monitoring and management of the equipment are independently completed by users. IDC data center provides IP access, bandwidth access, power supply and network maintenance. In the latter, IDC data center rents physical equipment for customers to use and is responsible for the stability of the environment. Users don't need to buy hardware devices.

The services provided by cloud computing are a set of continuous services from infrastructure (Iaas) to business infrastructure platform (PaaS) and then to application layer (SaaS).

IDC data center integrates large-scale hardware servers into the cloud to provide users with service capabilities and IT efficiency. Users don't have to worry about the performance limitations of any hardware devices, and they can get high scalability and high available computing power.

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

In the final analysis, cloud computing is a dynamic resource allocation through resource intensification. Traditional IDC services can also achieve simple intensification, but there are great differences in the speed and scale of resource integration. Traditional IDC only carries out limited integration on the basis of hardware servers, such as multiple virtual machines * * * enjoying the performance of a physical server. However, this simple intensification is limited by the resource scale of a single physical server, which is far less effective than the large-scale integration across physical servers and even data centers.

More importantly, the resources provided by traditional IDC can't withstand the rapid redistribution in a short time.

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

Cloud computing can realize the rapid redistribution of resources through newer technologies, and can allocate resources in a few minutes or even tens of seconds to achieve rapid availability, while the huge resource scale in the cloud virtual resource pool can withstand the rapid redistribution of massive resources, thus effectively avoiding the risk of idle resources.

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

More flexible resource application methods and higher technology upgrades enable cloud service providers to have collective advantages and innovate resource utilization methods, thus promoting the operational efficiency of the whole platform. Moreover, unlike traditional IDC services, cloud computing liberates users from the management and operation and maintenance of hardware devices and focuses on the development and innovation of internal business. Cloud service providers are responsible for the stability of the cloud platform itself. This responsibility sharing model improves the operational efficiency of the whole 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, which improves computing efficiency and makes the efficiency and scale of resource redistribution not limited to a single physical server or even a single IDC data center. Compared with traditional IDC services, cloud computing has greatly improved in delivery/service mode, resource allocation scale, resource allocation speed and the operating efficiency of the whole platform, which will create higher value for enterprises and developers in various industries.

5. Can traditional IDC hold up?

In the past, the traditional games that sold space by installing a virtual host software on several servers have become less and less marketable, and the traditional IDC with a slightly larger scale has also begun to upgrade to vps. But at present, vps is very popular, and it is very expensive for customers to develop. On the other hand, due to the trouble of filing, a large number of small and medium-sized webmasters and blog sites turned to idc companies in the United States or overseas, and several established idc companies abroad basically realized virtualization and basic cloud computing, with extremely low prices.

The survival of traditional small IDC will be more difficult. If Sina, Shanda and Alibaba Cloud's computing products get through the filing channel, a large number of customers who originally belonged to IDC will transfer to cloud computing providers at a high speed, which is almost unstoppable. In addition to server hosting, the virtual hosting business of larger idc vendors in China will also be severely impacted. In addition, several major cloud computing companies are well-known enterprises, and consumers trust them far more than idc vendors.
