Unanswered: application and database on 2 different servers
I need a company to host my "MySQL database" (big one: millions of rows!) only, without my application to be able to quicly move from a hosting plan to another (application) without moving my database and stoping the website for a period of time. Which means, my application and my database will be on different servers.
I need a confident company which I can trust. Anyone can help? And I need to know if the fact that I put my application and database on 2 different servers may causes problems like slow respond, performance, etc.
