Config Management Camp 2024 Ghent

Currently there are close to twenty configuration management systems here at Config Management Camp 2024 in Ghent .
The Configuration Items (CI) receiver their configuration information through either push or pull and then either are being configured by remote control or as an independent agent.

One of the challenges we face is the provisioning of external data, enter Data. Data serves any CI that is able to send, receive and process messages. There are, for now two types of messages Data is able to receive and process:
- Feeds triggering a response
- Service views

Data makes use of a PostgreSQL backend that has schema's accordingly:
- feeds
- context
- knowledge
Data stores and processes the information it receives from the CI feeds into the context schema
Data processes information from both schemas for use in the knowledge schema.
- The CI's in the landscape provide Data with facts or hard classes of itself in the feed message, which triggers a response by Data with a configuration view.
- Services views are specific requests to Data and trigger responses to the requestor concerning information about the landscape.
Configuring items in an IT landscape require, next to pure configuration details, information on a variety of levels. The information is related, among other things to:
- Organisation
- Domain
- Users
- The specific item itself
- Information about the environment, that relates to the purpose the item has within the IT landscape

The Data class architecture has convergence in mind. Convergence is the theoretical model in which CI's convergently work towards their desired state.
