Cloud service era arrives, cloud IDC product

Cloud Host service is an important part of cloud computing services, and it is a service platform for all kinds of Internet users to provide integrated business capabilities. The platform integrates the traditional Internet application of three core elements: computing, storage, network, user-oriented Internet infrastructure services to provide public.

Cloud host services include two core offerings

For SME users and high-end personal users of cloud server rental services;
Flexible computing platform service for large and medium sized Internet users.

Cloud host can effectively solve the traditional physical rental and VPS services, the existence of difficult management, business expansion of the weak defects. In the actual application of the cloud host has three aspects of resilience:

Each cluster node of the cloud host platform is deployed in one of the backbone rooms of the Internet, which can provide computing, storage, online backup, hosting, bandwidth and other Internet infrastructure services independently. Cluster nodes are composed of the following hardware:

Management Server: The use of dual-machine hot standby mode, the entire node of all computing servers, shared storage, network management, while providing external management of the entire node API. The Management Server provides:

Manage Services (compute servers for management nodes, external management interface), DHCP service (IP for network boot assignment for Compute server), TFTP service (remote boot image download for Compute server network startup), NBD Service (Network block device service for compute server). The Management server also runs a data acquisition program that periodically collects and sends a variety of performance data to the central data collection server: Storage servers can be iSCSI or x86 servers with built-in storage capacity, and a unified storage pool through a clustered file system. Provides logical disk storage, unstructured data storage, and consolidated backup services for virtual machines within a node.

Compute server FARM: Compute server is a highly configured four kernel server, compute server does not need to install operating system, but must have network boot function, it runs a Linux micro-kernel, cloud computer software, an agent that communicates with Management Server

Switch: According to different functions and node performance requirements of a number of three-tier switches, responsible for the management of network segments, public network switching network segment, internal Exchange network segment, storage network segment, etc.

1, the best TCO: Brand server, no deposit, monthly payment, on-demand, the best total cost of ownership.

2, the National coverage: cloud computing nodes distributed in the country's backbone rooms, BGP, dual-line, one-way, customers can choose independently.

3, Fast supply: resource pool and built-in a variety of operating systems and application of standard mirrors, the demand whether it is a hundred, Windows or Linux, can achieve instantaneous supply and deployment.

4, on-demand elastic expansion: To protect the user investment and no need for system, environment and data to make any changes, you can quickly achieve the cloud server configuration on-demand expansion or reduction.

5, high reliability and rapid recovery: Enjoy the international brand of enterprise-Class Server performance and reliability, built-in monitoring, standby, snapshots, data backup and other services to ensure rapid recovery of failures. Provides intelligent backup capabilities to minimize data risk.

6, Easy-to-use, easy management: Provide a variety of management tools, do not understand the technology can also be used!

7, security: From the hardware level to achieve fault and security isolation, platform built-in ARP attack protection capabilities, distributed and large-scale to enhance the ability to prevent DDoS attacks.

8, High-performance: Cluster virtualization, real physical isolation, the cloud server exclusive memory and other hardware resources to ensure high-performance.

9, a key deployment components: the United Nations within and outside the well-known software manufacturers forum, E-commerce and other functional cloud server components, without any installation and configuration work, to achieve a key deployment software system.

10, sla:24*7 Professional operation and maintenance service team, providing the highest level of SLA.
