I. Demand Stimulates Business
With the term IDC being more and more seen in the media and reviews, the technology, services and development of the IDC (Internet Data Center) are also being paid more attention to.
The emergence of IDC and the development and application of the Internet are very closely related. The popularization of the network, the convenience of online information transfer and the development of e-commerce, so that the application of online has become more critical, especially network content providers, network service providers, application service providers, etc. of their own Web site system performance, cost, reliability, scalability and other needs are very urgent. In addition to meeting this series of needs requires easy, continuous and low-cost access to high-quality network bandwidth, hardware equipment, technical support and network management and maintenance, the requirements of the server room is also very strict, in general, the power, air conditioning, fire, security and other requirements 24 hours a day.
IDC is to meet the above needs of users and appeared. As an IDC, first of all, it is necessary to establish a high-quality server room that can meet the customer's needs for continuous development, and at the same time, it is able to obtain all kinds of telecommunication resources (fiber optics, bandwidth, trunks, private lines, etc.) in a large scale and centrally, and it possesses rich technical resources (all kinds of professional and technical personnel, such as network management engineers, service support engineers, personnel for the application and research and development of new technologies, security engineers, and experts in system analysis, etc.), which can provide 24×7 support for the users' The network system of the user to provide 24 × 7 all-weather basic services and technical services, so that the user more focused on their core business, to get more returns.
Two, technology to build IDC
In technology, as an IDC service provider, first of all, to make the standards of the server room to meet the user's needs; at the same time, it should be able to provide users with different applications of the corresponding network services and value-added services, so that the user can lower investment to obtain more resources and services, and more focused on its core business, improve competitiveness. Specifically, IDC involves the following four aspects of technology and services.
1. Server room construction and operation
A telecom-grade server room that meets international standards is the most basic facility of IDC, and the technical issues to be considered in the construction and operation of the server room are as follows:
● Power supply Calculation of power supply capacity for a large-scale server room area, redundancy power supply capacity for n+1, UPS loading capacity, automatic switching of circuits, consideration of fire-retardant cables, and switching and switching. Switching and so on.
● Temperature and humidity control Thousands of high-density placement of servers in operation will cause a rise in temperature, and temperature and humidity have a great impact on the normal operation and service life of the servers, so the most reasonable way of air supply, intelligent temperature and humidity control and alarms are the key to the design.
● Cabinets and cables Independent power supply, main/standby power supply, various cabinet accessories, and various cables (Category 5 cable, single-mode/multi-mode fiber optic cable, and wired cable).
● Fire Protection Facilities Fireproof and flame-retardant materials, temperature-sensitive and smoke-sensitive fire monitoring and alarm systems, gas extinguishing devices and perfect fire protection measures.
● Security Facilities Access control system that can be suitable for different security strategies, all-round and dead-angle CCTV monitoring system, infrared alarm system, 24-hour security guards and emergency measures.
2. Network Establishment and Maintenance
A variety of network resources and high-speed bandwidth resources are the basis of IDC service capacity and service quality assurance, in the establishment and maintenance of the network, the need to optimize the network design, routing design and network management capabilities to ensure.
● Network design The design of network topology requires complete redundancy of nodes at all levels, fast and non-blocking data transmission and exchange, good network scalability, and reasonable overall network structure.
● Various accesses Fiber optic, DDN, Frame Relay, DSL and so on.
● Routing technology Various routing strategies, dynamic routing protocols.
● Network management technology Network performance monitoring, fault alarms, trend estimation and the health of each switching and routing node, the user's automatic alarm system for emergencies, etc.

3. Service and management of user network systems
Users host some or all of their servers in the IDC, and it is very important for the normal operation of these systems to be monitored and alerted. In addition, the ability to give the user's technical director and network management engineers more network operation data will provide effective help in system maintenance, troubleshooting, expansion planning. These monitors include: power supply continuity monitoring, network connectivity monitoring, traffic monitoring, response time monitoring.
4. Other value-added services
For those engaged in e-commerce, providing application services for the site, high-speed, uninterrupted is the root of its services, data storage security is the guarantee of its services. Many new technologies have come into being and some traditional technologies are going online. Therefore, the IDC business within the corresponding value-added services and technologies, such as: data backup, load balancing, Cache technology, firewalls and so on.
Three, customer demand-driven IDC
IDC's development service direction depends largely on the further improvement and development of its customers' demand, analyzing the current foreign and domestic larger IDC, its services are mainly focused on:
1. Basic services
This service to provide high-quality server room environment, service quality assurance of the Bandwidth and network resources rental and on-site technical support services. It is roughly divided into: server hosting, whole machine rental, independent server room rental for large customers, and a variety of dedicated line access services.
2. Management services
Management services provide users with various levels of monitoring and reporting services, data backup services and website high availability services. In general, there are data backup, monitoring of network conditions and application performance, and load balancing services.
3. Security services
Security services are security protection services provided by IDC to users. It includes: managing firewalls and virtual private networks (VPNs).
4. Expert services
Expert services refers to the user's special needs, to provide a full range of services from web site design to hosting management, to provide this service IDC needs to have applications, systems and networks in all aspects of the engineers and strong technical force, at present in the country can really do this kind of comprehensive expert services are only a few IDCs. Fourth, the IDC technology trends
With the continuous development of e-commerce, enterprise hosting business to further understand and domestic data centers continue to improve, data centers to provide customers with a package of optional services will soon become inevitable. This package of services include: the provision of standard server room, server hosting, bandwidth rental, monitoring, security management, providing application software and database network platform, and then provide users with a complete website system solutions.
On the other hand, the services will also be oriented to different user characteristics to further refine the user can choose different services according to their own application characteristics and different collocation, in order to maximize the benefits of the user. From the technical side, several different levels of development should be considered:
● Network Quality Different network qualities (routing and switching levels, bandwidth availability, and minimum latency guarantees) correspond to different service quality assurances (SLAs), as well as to different user needs and different service prices. Applying quantitative network qualities to the provision of different levels of service can be more relevant to users.
● Centralized Data Storage and Backup ***Enjoying expensive storage devices and backup systems is undoubtedly a very good way to go, but it requires more reasonable technology to ensure the security and reliability of all storage and backup data, as well as high-speed data recovery capability. The development of broadband allows more users to use offsite/remote data backup services to achieve a higher level of security assurance.
● CDS technology Content Delivery Service (CDS) is a combination of multipoint load balancing and Cache technology that utilizes intelligent distribution technology to distribute website content to multiple nodes based on the location of the visiting user and in accordance with the principle of proximity access. CDS technology increases the speed of the website by 30% to 50% and saves large sums of money to build mirror sites.
● Network security monitoring In addition to firewalls, network security scanning, virus scanning, real-time security monitoring, and a variety of hacker prevention measures are based on continuous technological development.
Overall, in the IDC business, no matter which aspect of the development of technology comes from three aspects: First, more and more users use IDC services to make the IDC service varieties more refined and hierarchical, which requires the use of more innovative technology; Second, the user is more focused on its core business, the need to be more associated with IDC outsourcing way to achieve the work, which drives IDC to develop more innovative technologies. This drives IDCs to develop more technologies to meet user needs; and finally, the emergence of new technologies drives IDCs to continuously update their technologies to remain competitive.
