Some are willing to let clients run on versions that have long since been replaced. Others are stricter about clients staying closer to the most current version of the application. Different code bases may run on different operating systems, for example, a Windows version and a UNIX version. If the application was written relatively recently, this shouldn’t require different code bases. There may be a client-server version of the application and a web-based version of the application. If they were written in different languages or by different teams, then they might not share a single code base.
The exact ways in which it might make your job harder depend on how it was implanted, but some possible ways are: • • • • • Installation will be more time consuming because there will be more servers to load the software onto. Shutting down and starting the system will be more difficult. , server “A” has to come down before server “B” can be shut down. Monitoring log files will be more time consuming simply because there are more of them and they are spread out across multiple servers. Monitoring the overall system will be more difficult because there are more servers to watch, but also because you won’t want to generate false alarms.
Applications that have been written to take advantage of a 64-bit operating system will perform better on a 64-bit system. 12 Storage 33 Operating systems come in a wide variety of sizes and level of complexity. The largest supercomputer in the world has an operating system and so does your microwave oven. The servers that your application runs on will almost certainly have an off-the-shelf, commercial operating system. 11 WINDOWS VS. UNIX VS. LINUX Arguments about which of these operating systems are the best or the worst can quickly escalate into a religious like furor.
