Hi Folks, In today's tutorial, we will be looking at a very interesting topic called Servicenow Mid Server. We will learn in terms of ServiceNow what is mid server. You can consider this tutorial as a complete guide to Servicenow mid-server installation in 20 min. So let's look into what is ServiceNow mid-server in detail and how it works according to ServiceNow docs. Management, instrumentation, and Discovery (MID) Server is a Java application that runs on a server on your local network. MID Servers facilitate communication and data movement between a single ServiceNow® instance and external applications, data sources, and services. What is a MID Server used for? MID Servers help you to control and secure how ServiceNow communicates with your organization’s systems, especially those behind a firewall. This supports four primary use cases: 1. Integrations Supporting LDAP, JDBC, REST, and SOAP-based integrations to systems on your intranet 2. Orchestration Enabling orchestration with other systems via either workflow activities or IntegrationHub spokes 3. Discovery Providing access to systems for traditional CI discovery and/or to support discovery needed for service mapping 4. Language processing Running other types of code (PHP, Perl, Ruby, etc.) as a script on the MID Server to interact with systems that require those languages What are best practices for using MID Servers? 1. Task each MID Server with only a single-use – For example, discovery, orchestration, etc. 2. Deploy on a Windows server – A Windows MID Server can perform discovery and automation on both Windows and Unix, but a Linux MID Server can only perform operations on Unix. 3. Cluster-like MID Servers – When set up in clustered groups, ServiceNow automatically balances the load on discovery across the different MID Servers and they act as a failover for each other if one MID Server goes down. 4. Place MID Servers close (network-wise) to the internal resources they’re communicating with – This improves performance. The MID Server runs as a Windows service or UNIX daemon within your organization’s network (behind the firewall) and is completely controlled by your organization with local configuration files. It initiates communications with the ServiceNow instance via the MID Server External Communication Channel (ECC) Queue
