I have cloud server at RackSpace that has 2GB of memory. OS is Windows Server 2008 R2 x64. As of now server is pretty fast. I plan to configure IIS and install SQL Server Express 2008 R2 x64, so memory is somewhat at a premium. There will be no users on the server to generate real load, I got it for educational purposes.
I also would like to install PHP and MySQL to familiarize myself with this technology. However, I have no idea about how much memory they require to work (I don't care if they are slow) and if it will bring server to a crawl.
Can anyone give any feedback if what I want to do is viable on 2GB of RAM?
