To have a Web site on the Internet you first need to have a Web server. Unfortunately, owning a Web server can be very costly and requires technical expertise that most businesses don't have. This is where Web Hosts come in. Web hosting companies provide the equipment and other technical resources that you need without the headaches that come when you have to do it yourself.
Think of a Web Host as the landlord of building. A landlord rents out storefronts to various businesses. Each business decorates and runs their store differently, and doesn't worry about the maintenence of the building. In a similar way a Web Host rents out space on a Web server, (or entire Web servers), to various businesses. Each business builds their own Web site and never has to worry about the maintenence of their Web server.
In other words, the Web Host provides the place on the Internet where your Web site lives. It's a lot cheaper than buying you own server, and you don't have to hire the technical staff to take care of it.
Shared Server: Shared servers offer clients the ability to host their Web site on a powerful, professionally managed server, at a low monthly cost. Shared servers provide individual Web sites with redundant connectivity, 99 percent uptime and 24/7 monitoring for a fraction of the cost of a dedicated server.
- Intended Clients and Uses
Shared servers are an excellent solution for entry-level hosting needs. Designed to host small scale e-commerce sites and static Web pages, shared servers offer first-time Webmasters a reliable Web presence without advanced technical skills.- Server Response Time
The activity of other sites and the number of other sites on the server can affect shared server performance.- Flexibility and Scalability
As you are restricted to the server box space, upgrade capacity is primarily focused on disk size and throughput.- Software
Shared Servers are limited to the software that is installed by hosting provider.- No technical skills required to use a shared server.
Shared server hosting provides a cost-effective way for entry-level Webmasters to maintain a reliable Web presence without extensive technical resources.
Virtual Private (VPS) Server: Virtual Private Servers (VPS) combine the flexibility of a dedicated server with the economical prices of shared server hosting. VPS Web sites reside in private and protected areas on a shared server and maintain an independent set of applications, allowing the client to share the expenses of hardware and network connections while maintaining a secure allocation of RAM and CPU.
- Intended Clients and Uses
Virtual Private Servers are intended to meet entry- to mid-level hosting needs. The potential functions of a VPS are wide and varied. It can be used as a simple FrontPageŽ server or as an advanced, database-driven commerce server.- Server Response Time
Virtual environments are not affected by the activity of other sites on the server, but their allocated resources limit site performance.- Flexibility and Scalability
Upgrade capacity is primarily focused on disk size, number of processors and throughput.- Software
As you maintain your private section of the server, you are able to incorporate many software options.- Moderate technical skill level is requred. UNIX administration, basic programming, and database capabilities are needed to operate a VPS.
Virtual Private Servers provide customers with an independent set of Web applications to handle more advanced Web-based applications, without the costs associated with a dedicated server.
Dedicated Server: Dedicated servers are a single computer fully devoted to the needs of one customer. They allow for faster access to information and provide the customer with greater flexibility to add advanced database and e-commerce applications. As the customer does not share RAM, disk space or a connection to the router, dedicated servers provide customers with the most advanced Web hosting solutions.
- Intended Clients and Uses
Dedicated servers are designed for mid to advanced-level hosting needs such as "mission critical" and high-traffic sites. The servers can handle heavy data-driven sites, advanced e-commerce programs, video streaming, and multimedia programs.- Server Response Time
Dedicated server response time depends solely on the volume of activity on the customer's Web site.- Flexibility and Scalability
All aspects of the platform (disk space, memory, etc.) are upgradeable since dedicated servers are single client machines.- Software
Unlimited ability to download software programs to your server.- Advanced technical knowledge is recommended-experienced programming and database capabilities.
Dedicated servers provide high levels of security, connectivity and scalability, to support high volume and mission critical Web-based applications.
