Deciding on a server rental can easily be the most important piece of technology any business might need to acquire for a short term rental. Not just for their all-around usefulness but for their critical role in business operations such as a data center relocation, application testing, or simple added horsepower to augment your existing infrastructure for a short term project, such as video rendering.
The answer to this question largely depends on two factors. Are you new to server technology and not very interested? In this case, Windows is the easiest option to get where you want to go. Do you already have experience with Linux or would you like to familiarize yourself with this operating system? If so, Linux gives you more freedoms to configure your server, and you will be using an operating system that is less vulnerable to attacks from the Internet. Linux is also open source and therefore free.
