When you have many cloud resources, or when your blueprint design server and clouds are not in the same region, communication between the server and clouds can slow down. This communication is faster when you cache information about flavors, regions, and images on the cloud discovery service.
Caching is enabled by default on the cloud discovery service. By default, the blueprint designer does not use this cached information; however, now you can enable it. To use the cached information, you configure settings in the cloud discovery service and enable the cache in the blueprint designer system settings. As a result, when you access a cloud provider for the first time, the cloud discovery service caches the resources from that cloud, based on the settings file.
For the detailed steps on configuring these settings, see the topic, Caching artifacts on the cloud discovery service, in the Knowledge Center.
