Self Service
Glossary
Before you start using Self Service to manage your applications and streams, it is important to understand its basic concepts. The following Glossary helps with that.
- Stream
-
a stream represents a flow of information (messages), which is continuously updated
- Application
-
an application represents anything that is responsible for producing and/or consuming data on a stream, whether it is a Java or .NET app or a connector
- Cluster
-
a cluster represents a physical messaging unit consisting of Kafka, Zookeeper and a Schema Registry
- Environment
-
an environment is used to logically and/or physically separate resources on a Kafka cluster. Environments are mapped to a physical Kafka cluster through the instance (see below). Whereas public environments typically map to the application lifecycle, private environments are used to isolate a team’s apps and streams.
- Instance
-
an instance provides an abstraction layer over 1..n clusters, making sure that all data within an instance is synchronized and all streams in different environments mapped to this instance can exist on the same underlying Kafka cluster.
- Tenant
-
a tenant in Self Service is no other than a reference to your company and it’s context in which streams, applications, environments, instances, users and groups exist

Dashboard
As soon as you log in, the dashboard will be shown. Here you have an overview of all stream access requests that need an action, are pending, approved, denied or have been revoked.
If you are a member of the group owning a stream, the action needed list is displayed when you first visit the page. Otherwise, the pending requests list is displayed.
Stream graph
In this page you can see a graphical representation of all applications consuming and producing streams in the selected environment. Use the dropdown in the top to switch to a different environment.
Streams
The Streams overview displays a list of all streams:
Stream detail
Clicking on a stream takes you to the stream’s detail page:
The top section of the page describes the details of the stream, such as the Key and Value schema type and schemas and the retention policy.
If you are a member of the group owning the stream, you will also see an Edit stream button on the top right corner.
The middle section of the page titled Deployments visualises the stream itself and the producer and consumer applications surrounding it. Applications displayed in green have been approved to produce to or consume from the stream, while others in grey are awaiting approval. Use the dropdown on the right to switch to a different environment.
The bottom section of the page shows the pending and approved access requested by the applications. This section is only visible to owners of the stream. For any pending request, in the Pending streams tab, there is an Approve request button, which can be used to approve the request on a particular environment and a Deny button, which can be used to deny the request. In the History tab, all applications that are already approved or denied, on an environment, are shown.
Applications
The Applications page displays a list of all applications:
Application detail
Clicking on an application takes you to the application’s detail page:
The top section of the page describes the details of the application. If you are a member of the group owning the application, you will also see an Edit application button on the top right corner.
The middle section of the page titled Deployments visualises the application and the streams (topics) it produces and/or consumes from any environment. The dropdown on the right can be used to switch to a different environment.
The bottom section of the page shows the streams where this application has produce or consume access under History tab. If the application has requested access (pending approval) it is also shown under the Unapproved requests tab.
To create a new access, click the + Add request button.
Environments
The Environments page displays a list of all available environments. In the "Environments" overview, only public environments are shown, as well as private environments owned by a group you are member of.
