The more physical memory your VPS has, the more applications you'll be able to run at the same time. Some pieces of software require loads of RAM even when nothing else is running on the web server, even though they might not require high CPU speeds or plenty of disk space. In case your server runs out of memory, it will stop responding and the websites and the offline apps you host on it won't work effectively, as their software components shall not load since there will not be any free memory. In this light, we offer a RAM upgrade for our VPS solutions, thus if you notice that your web server is close to the limit, you could take full advantage of this upgrade without upgrading the whole package and paying for resources that you will not use. In this way, you'll be able to ensure the proper operation of your scripts and stop worrying that your visitors will see errors or won't be able to open your Internet sites at all.
