# Hermes Messaging Service components

The Hermes Messaging Service architecture is built on the following components.

|Component|Description|
|---------|-----------|
|Hermes Message Queue|A dedicated multi-tenant message queue in the ServiceNow Hermes Kafka cluster for managing the flow of data to and from the instance. The message queue uses certificate-based authentication that supports bi-directional traffic. The Hermes Message Queue is available to ServiceNow applications via the Hermes Glide API.|
|Hermes Gateway|Part of the ServiceNow datacenter that enables you to connect to a ServiceNow endpoint to read and write data to the Hermes Message Queue.|
|Hermes Glide connector|Connector that integrates instance functionality \(for example, flows, data export, and data replication\) with the Hermes Message Queue via the API.|
