Due to the large number of users using WordPress, several web hosting providers have chosen to offer managed WordPress hosting. An account with one of these providers only allows you to host WordPress based sites and nothing else. The benefit of managed WordPress hosting is that you do not have to worry about ANYTHING. They optimize your site for performance, make sure that your site is secure, and keep regular backups. On top of that they advise you if a specific plugin is having a negative impact.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
A2 Optimized is a product of our team of WordPress experts who noticed a concerning trend of users loading their WordPress sites down with plugins to try and get the fastest, most secure setup possible. Unfortunately, in most instances, too many plugins can actually make a WordPress install slower and less secure. That's because each installed plugin generally slows down a WordPress site and many times these plugins are not updated often enough. Out of date plugins make WordPress sites particularly vulnerable to exploits.
