MySQL, as we know, is an open source database management system (DBMS). On your Managed server or Linux shared web host, this DBMS comprises of a collection of tables that stores business critical data in a structured format. But the MySQL working withinyour Managed Server is different from anyother Linux shared hosting package. 

A few of these differences between MySQL for Linux Web Hosts and Managed Servers have been discussed here.

- With a Managed Server you can make many MYSQL databases available for your users. A DBA can set up as many as 100 MySQL databases on sucha server used by you.

- Where are such databases stored? 

Every single database concerned with a Managed Server is stored with in it shared drive space. Your system can make use of each one of these resources so that high loads on MySQL can get managed easily. Since information is stored internally in these databases, data requested are processed within a fraction-of-a-second. Hence quick response time is an added advantage.

- MySQL databases can be expanded as per your data storage needs. It is just that this repository can be expanded upto a limit that is redefined by a servers hard drive capacity. All these databases are stored on the server itself and localhost is the host address for your MySQL Database. 

- In case of MySQL5 databases, a DBA has to specify accurate socket for connection.This information can be appended to the host addresses end. 

An example is as follows:

localhost:/tmp/mysql5.sock1

- Information concerning each of these databasesis available in the 1&1 Control Panel. In case you are unsure, it can be located under the MySQL Administration section.

- No size quota exists within a given MySQL database on Managed Servers. As a customer one use the entire disk space of the server. 

Hence, any MySQL databases associated with any shared hosting plan must not consume anything above one third of the disks total capacity. In case it does, enough space will not be available to take backup dumps of your MySQL database.
