| DB Server |
|
Cannot access to DB server from outside, because of it has a local IP address. It only communicate with App Server. It is possible to extend DB Servers by using DB that can be clustered like Oracle. If clustering is impossible, another solution is to synchronize per specified period by using DB synchronizer developed by HolyNet.
|
| App Server |
|
It is a server for various applications, without any Web Server. Also have a local IP address, so it is impossible to access from outside. It only save and read data from DB servers by communication with Web Server. And whenever you want, you can extend these App Servers.(various kinds of CGIs are belongs to here.)
|
| Web Server |
|
It has both internet IP addresss and local IP address with each 2 NIC and works only as a Web Server where the clients connect to. Also possible to extend these Web Servers.
|
| L4 Switch |
|
Load Balancing. This can be substitue with holy load balance(HLB), which is on the developing.
(In addition, you can locate backup servers, file servers and main servers.) |
|
This frame makes it possible to serve your web pages keeping stability, even though specific application servers meet a problem. Also these non-critical problems are preventable using HLB(on developing, yet). You can also substitute high priced L4 Switch with HLB, then you can save your costs.(Two clustered machines will more be effective than high priced One machine.) |
