4. known system limitations
Performance limitation: if it comes to high-performance scenarios, and A&AI happened to be needed for alarm analysis and correlation, there could be a performance bottleneck as all A&AI API calls are based on HTTP requests, which is considerably time-consuming.

6. New Release Capabilities
According to Requirement 479 (see below), all sub-components of DCAE have to migrate their deployment from Cloudify blueprints to Helm charts.
DCAE will keep the cloudify-blueprint deployment as a fallback in case the migration can not be completed in Honolulu. Once the migration is done, deployment of DCAE apps (including Holmes) will be all based on Helm charts.
