Now there may be a lot of people about cloud computing, data center and large data and places feel fuzzy, this kind of technologies such as cloud computing data center is a kind of based on cloud computing architectures, loose coupling calculation, storage and network resources, full virtualization of the IT equipment, high degree of modularity, high degree of automation, a higher degree of green energy saving of new data center.
The cloud data center is characterized by a high degree of virtualization, which includes virtualization of servers, storage, network, and application, enabling users to invoke various resources on demand.Followed by the degree of automation management, including the management of the physical servers, virtual servers, the related business process management automation, automated management of customer service charges, and at last the green, energy-saving, cloud computing data center in all respects in accordance with the green and energy saving standard, general PUE value less than 1.5.
What's the difference between a cloud computing data center and a traditional IDC?
In terms of design concept, cloud computing data center (or a new generation of data center) is more emphasis on the collaborative optimization with the IT system, on the premise of meet the requirements, achieve the highest efficiency and lowest cost of the whole data center;Traditional data centers usually emphasize the reliability, safety and high standards of the machine room, but they are separated from IT systems and are expensive.
Traditional IDC type can be roughly divided into custody services and users' service pattern, one kind is the server purchase by users themselves, monitoring and management of equipment during the period of work is done by customers themselves.Data centers mainly provide IP access, bandwidth access and power supply services.Is another pattern of data center not only provides management services, and also to provide customers servers and storage, customers need to purchase equipment can be used to storage space and computing environment provided by the data center, but now entered the era of cloud computing IT industry, in the aspect of data center hosting is no longer requires the user to provide your own hardware equipment, IT greatly increases the computing power of the hardware and IT scalability and operability.
(1) the difference between cloud computing and traditional IDC in resource intensive speed and scale.
In the end, cloud computing is a dynamic resource allocation through resource intensive implementation.Traditional IDC services can also achieve simple intensification, but they differ greatly in the speed and scale of resource integration.Traditional IDC only has limited integration on the basis of hardware servers, such as multiple virtual machines sharing a physical server performance.But this simple intensification is limited to the size of a single entity server, far less than cloud computing, and even a massive, effective integration across data centers.
More importantly, the resources provided by traditional IDC are difficult to handle quickly and redistribute quickly.
(2) the difference between cloud computing and traditional IDC in operating efficiency of the platform.
The more flexible resource application mode and higher technology upgrade will enable cloud service providers to have the advantages of collection advantage and innovative resource utilization, which will promote the operation efficiency of the whole platform.And, unlike traditional IDC services, cloud computing users from the hardware management and operational work, focus on the development of internal business and innovation, by the cloud service provider is responsible for the stability of the cloud platform itself.This responsibility sharing model improves the operation efficiency of the whole platform.
In short, cloud computing is an extension and development of traditional IDC services.Cloud computing is more compute nodes connected into a large virtual resource pool to improve the efficiency of computing, redistribution of resources efficiency and the scale is not limited to a single physical server or even a single IDC data center.No matter from delivery/service mode, resource allocation, resource allocation rate, or running efficiency of the whole platform, compared with the traditional IDC services, cloud computing is greatly promoted, the promotion for enterprise and developers from all walks of life to create a higher value.
(3) the difference between cloud computing and traditional IDC in service type.
Commonly used traditional IDC services include entity server hosting and hiring.The former is managed by the user to buy hardware to room and equipment during the monitoring and management work of the unilateral independently by the user, IDC data center offers IP access, broadband access, power supply and network maintenance, etc., which is rented by the IDC data center physical equipment for customers to use, and is responsible for the stability of the environment, users need to purchase hardware equipment.
The services provided by cloud computing are the complete set of services from infrastructure to the business infrastructure to the application layer.
IDC data center integrates the large-scale hardware servers into the cloud, providing users with service capabilities and IT capabilities.Users do not need to worry about the performance limitations of any hardware device, and can achieve high scalability and high availability of computing power.
(4) the difference between cloud computing and traditional IDC in resource allocation.
As is known to all, due to the deployment and configuration of physical hardware resources of traditional IDC delivery usually take hours or even days, would increase the time cost of companies, and more energy consumption, and difficult to achieve real-time, rapid redistribution of resources, and easy to cause idle and waste of resources.
Cloud computing, by updating the technology to realize rapid redistribution of resources, can in a few minutes or even dozens of seconds allocates resources available to achieve rapid, and the sheer scale of the cloud virtual resource pool resources make the rapid redistribution of resources is able to bear, and in order to effectively avoid the risk of idle resources.
(5) the difference between cloud computing and traditional IDC charging mode.
Traditional data centers typically charge in accordance with the month or year, calculation of standard is the number of cabinets, size of bandwidth, electricity use these data, the data is extensive, statistics is not accurate, often cause a lot of waste of resources.Such as a client to rent ten cabinets, but actually it only took five, five other can be slowly go online in the future, but you must pay the cost of the ten cabinets, let the customer more spent a lot of money.And cloud data center is different, can according to the hours or even minutes to collect fees, and customers to use is calculation, bandwidth and storage of data, like home with gas fee, as long as you don't open the gas burner, gas fee, also won't spend only at the beginning of the open kitchen burning gas is gas meter, accurate measurement, the cloud data center is to charge according to this model, the customer with how much computing and bandwidth resources, how many fee, this fee can be accurate to the minutes, save the expenses for the customer, so what customers don't like it.
(6) cloud computing is different from traditional IDC's requirement for optical devices.
Compared with traditional devices, the device density in the data center is higher, and more modules can be inserted on the same board card.Power demand has plummeted to one-eighth of the level.The need for speed is also more and more high, because in the limited space, limited in order to achieve a greater amount of data on the board, request the speed of the module has soared, all of these requirements, put together, for devices, the requirements of the integration is higher and higher.
Can traditional IDC still hold?
The past tradition of on a few servers, with a virtual host software on selling space play, more and more out of the market, slightly larger traditional IDC also began to upgrade to VPS, but the VPS, for the moment, popularity is very general, and expensive, customer development cost is high.Due to record trouble, on the other hand, large quantities of adsense turned to the us or overseas idc, small and medium enterprises, established abroad several idc basically realized the foundation virtualization and cloud computing, and the price is very low.
It will be harder for the traditional small IDC to survive, so it is inevitable that a large number of customers that belong to IDC will be transferred to the cloud computing business, and this is almost unstoppable.Domestic big some of idc, in addition to the server hosting, its virtual host business also will be the hardest hit, with cloud computing several big manufacturers is a famous enterprise, consumer trust in them is much higher than idc merchants.
Conclusion:
Next, the new cloud computing data center will attract more companies as the landing time approaches.Look to the future, in the Internet industry, the traditional IT industry has begun to more and more enterprises into the service and operation of data center, which includes a lot of industry leading enterprises, some experts pointed out that in the next five to 10 years, based on cloud data center management and service mode will become more common.
