Definition and classification server

Defining the server
Server as a computer is connected to a computer network or the Internet, have a static IP, with high processing capacity and on which one to install the software to cater to other computers access to require provision of services and resources. So basically server is a computer, but is designed with superior features, storage capacity and data processing are also larger conventional computers very much. Servers are often used for storage needs and handling of data in a computer network or on the internet environment. Server is the foundation of all services on the internet, any internet service operators must also want to adopt a particular server.

Classification Server
Based on the method creates one server divided into three categories: virtual servers and dedicated servers and cloud servers.
Private Servers (Dedicated Server) is the server running on hardware and support equipment separately including HDD, CPU, RAM, NIC,. The upgrade to or change the configuration of the dedicated servers require changes of the server hardware.
Virtual host (Virtual Private Server – VPS): is the server is made by means of using virtualization technology to split from a single server into multiple virtual servers differently. The virtual servers have the same features as a dedicated server, but run to share resources from the original physical server. The upgrade or change the configuration of the virtual server is very simple, can be changed directly on the system management software. However the change of virtual server resources dependent and limited by the resources of the physical server.
Server cloud (Cloud Server) servers are combined multiple different physical servers with SAN storage system with superior speed access to server operations helps fast, stable, limit low downtime status. Cloud servers are built on cloud computing technology to easily upgrade equipment parts during use without disrupting the process of using the server.

The advantage is attention of virtual servers (VPS)

1.The cost is much cheaper than with physical servers. Cost savings initially.

2.Operate completely independently as the real server, have full server administration.

3.Guests can use to configure Web server or mail server.

4.Easily upgrade. Install OS quickly.

5.VPS servers operate completely as a server (server) separately, you gain full administrator VPS server with the highest administrator privileges, ensure high security.

6.VPS servers are very big saving investment costs initial server purchase server.

7.VPS can be used to set up Web Server, Mail Server and other server applications and can be installed separately on demand as well as easily share files, transfer data between branches.

8.No cost to buy equipment, maintenance costs.

9.Using a static IP and is granted unlimited static IP.

10.Is secured by the system Firewall, Anti Virus, Anti Spam professionally.

11.VPS servers easily upgrade server configurations on demand use (CPU, RAM, HDD).

12.Bandwidth, traffic transport used depending on the needs of customers.

13.Can reinstall the operating system from 5-10 minutes (necessary in an emergency to minimize down time of the system, the case of error, overload or network attacks).
