Self-managed architecture [es-connectors-overview-architecture-self-managed]

Data is synced to an Elastic deployment through self-managed connectors. A self-managed search application exposes the relevant data that your end users are authorized to see in a search experience.

Summary:

• Gives flexibility to build custom solutions tailored to specific business requirements and internal processes
• Allows enterprises to adhere to strict access policies when using firewalls that don’t allow incoming connections to data sources, while outgoing traffic is easier to control
• Provides additional functionality available for self-managed connectors such as the Extraction Service
• Feasible for air-gapped environments
• Requires Platinum license for full spectrum of features and self-managed connectors

The following diagram provides a high-level overview of the self-managed internal knowledge search architecture.
