Why do we use MID server? Purpose of using MID Server?

[IamAmolB]

What is the exact need of MID server except discovery?
Is there any need of MID server while integrating with any tool?

Here goes a complete list of options (from the wiki) of how the LDAP integration could be setup:

LDAP typically uses one of these types of communication channels: 
 A MID Server connection communicates over HTTP on port 80 by default. This communication channel does not require a certificate. The connection between the MID Server and the instance is over HTTPS (port 443). You can use the MID Server to import data over LDAP, but you cannot use the MID Server for LDAP authentication. Proceed to Define the LDAP Server. 
 A standard LDAP integration communicates over TCP on port 389 by default. This communication channel does not require a certificate. Proceed to Define the LDAP Server. 
 An SSL-encrypted LDAP integration (LDAPS) communicates over TCP on port 636 by default, This communication channel requires a certificate. Proceed to Upload the X.509 Certificate to obtain and upload the certificate. 
 A VPN connection communicates over an IPSEC tunnel. Purchase or create an IPSEC tunnel on your local network. Proceed to Define the LDAP Server. 
A MID server initiates one connection to an LDAP server via port 398, then initiates an encrypted HTTPS connection to an instance via port 443 to push data to the instance. When using a MID server, the instance does not make the connection to the LDAP server. The MID server does. 
The instance can also connect to the LDAP server directly, using LDAP or LDAPS, either over the internet or through a VPN tunnel. 
For more information about VPNs, Mid Servers, and LDAP, see You Don't Need A VPN Part II on the ServiceNow Community. 

I hope this helps.

Thanks,

When I have to use more of 1 mid server (for example 2 mid server) ?

For example I have to integrate AD and Microsoft SCCM. In this case How much mid served have I use?

Hi Amol,

The MID Server facilitates communication and movement of data between the ServiceNow platform and external applications, data sources, and services.

Hello Amol,

The MID server (Management, Instrumentation, and Discovery) is designed to ease communication with external systems. It is rather special, since it does not run on the instance; it is Java software that is installed in a customer's infrastructure. This gives the following advantages:

1)The MID Server has direct communication with others systems, since it is in the customers network. This is very useful for communicating with unencrypted protocols, such as JDBC.

2)Scripts that run on the MID server have access to the file-system and can include custom Java code in JAR packages.

3)The MID server only initiates connections. It does not accept inbound communication, and does not open any ports. This makes it more acceptable to security teams.

4)It offloads work from the instance, enabling to scale out horizontally.

Mid Server is used as a middle ware between service now and different data base servers to perform modifications at data level.Mid server is used to import the data into service now.Here is details of mid server :
