The word "appliance" often refers to a "home appliance" or "apparatus."
In the computer world, it means a device optimized for use in a specific field or purpose and possessing only the necessary functions and performance. Thus, in the case of an appliance server, it is a server designed for such a purpose.
An appliance server has the advantage of being less expensive than general-purpose servers. The server equipment itself is equipped with the minimum hardware required, the necessary initial configuration is done in advance, and the software to run on the server is installed before delivery, so the user does not need to have very high IT skills to install the server, and operating costs can be kept low. The server is also delivered with the software installed.
Furthermore, unlike general-purpose servers, only the necessary functions are implemented, so the load on the server itself is not so high, and responsiveness is often relatively good. In addition, since various tools for operation and management are available, it is easy for users to introduce the system.
On the other hand, it is difficult to convert the server to other applications, making it inflexible.
Appliance servers are available in various types, depending on their intended use. Therefore, the user should consider the following questions:
The user must first decide what he or she wants to use the appliance servers for.
Appliance servers provide the following services: a web server appliance for creating and browsing websites, a cache server appliance for load balancing network traffic, a mail server appliance for managing the sending and receiving of mail, and a security server appliance for protecting the company network. A security server appliance to protect security, a search server appliance to support search functions, and a storage server appliance.
One or more of the above functions can often be selected and provided as appliance servers.
Even if there is no dedicated person or department in charge of handling IT, a specialized vendor will take care of everything from installation to operation, including handling of problems when they occur, so users can receive solutions with relative peace of mind.
As mentioned above, there are various types of appliance servers for different purposes, but they are all the same in the sense that they provide an optimized system with the minimum necessary hardware and software.
The advantages of such appliance servers are as follows.
First, they are less expensive to install. This is possible because the software and hardware of the system are configured as the minimum necessary. Furthermore, the minimal hardware configuration reduces power requirements, making the system more likely to save energy.
The second point is that users can start using the system immediately. When a server is delivered from a vendor, the necessary hardware and software are already built in, so the user only needs to do a minimum of configuration and can start using the service relatively quickly.
The third point is the ease of operation. Because useful tools are provided to support operations, it is relatively easy to operate the server, even if the user does not have high IT skills.
On the downside, because the purpose of appliance servers is to focus on a specific application and pursue user benefits, as a result, they lack versatility as a server. Therefore, it is often difficult to convert appliance servers to other purposes because o the difficulty and often impossibility of changing settings or adding hardware.
In summary, the major advantage of appliance servers is that they are cost-effective in terms of installation and operation due to the fact that the system is tuned specifically for a particular application. On the other hand, because they are optimized, they are not flexible in terms of system modification or expansion, so it is important to understand their good points and bad points before deciding whether to use a general-purpose server or an appliance server. Therefore, it is important to understand the good and bad points and decide whether to use a general-purpose server or appliance servers.
