Internet Data Center (IDC) is developed along with the evolving needs of the Internet. It is an Internet Content Provider (ISP) enterprises, media, and various websites provide large-scale, high-quality, secure, and reliable professional server hosting, space leasing, network wholesale bandwidth, ASP, EC, and other services. Therefore, in a sense, it evolved from an ISP's server hosting machine room.
IDC is not only the center of data storage, but also the center of data circulation. It provides a high-speed Data transmission service (Data Delivery. It can be said that it appears in the most concentrated place of data exchange in the Internet. In such an IDC environment, what kind of virtual servers are suitable for selection? This article describes the selection of virtual servers for IDC users.
I. Application features of IDC Rooms
Evaluate the level of the IDC room. In addition to network resources, it is the hardware condition. Network bandwidth can be seen or felt. In hardware and facilities, part of the considerations are data center construction, area, security monitoring, power supply, and disaster prevention capabilities; the other part belongs to servers, firewalls, and other hardware devices.
Server equipment selection is crucial. It is inevitable to consider how to improve the high performance, high availability, high computing capability, and good scalability of E-commerce servers, and Server Load balancer. Due to the differences in the IDC network structure design, it is generally divided into front-end servers, application-layer servers, backend database servers, and storage servers.
The applications of servers on each layer are different, and the selected servers are quite different. For example, front-end servers directly interact with different application requirements of users, such as Web, FTP, email, newsgroups, and many applications such as caching and security, from the perspective of performance, reliability, and manageability, servers should be rack-mounted; middle-layer application servers mainly deploy business logic, such as ERP and e-commerce, servers that require high performance and high computing power also need to support Load Balancing through proprietary hardware switching devices. Backend data supports the deployment of large databases on servers. The SAN smart storage area network is used for centralized data storage and backup.
From the perspective of the level and scale of IDC data centers, there are telecommunications-level data centers, A-level data centers or backbone nodes, network company-level data centers, space rental data centers, and internal data centers of enterprises, it can be said that the IDC data center is uneven, and the server model varies widely.
We recommend that you select a rack-mounted Server Based on the server type. Due to the small size and high manageability of the Rack server, the IDC can take full advantage of the limited space to place the largest number of servers. In addition to being small and easy to stack, rack servers are also easy to manage and maintain, providing high-density computing power and good redundancy and scalability.
The above only analyzes some considerations for server selection at different application levels in the IDC room, combined with the mainstream virtualized servers. Servers at the frontend and intermediate application layers are common in the market. We do not recommend the backend servers that support large databases, such as SAN storage and storage servers.
