I didn't say that. There are at least 2 different roles application
developers/publishers and application users. Application developer is not
necessary cloud provider. The whole point of AppCatalog is to support
scenario when anyone can create and package some application and that
package can be uploaded by user alone. Think Apple AppStore or Google Play.
Some cloud providers may configure ACLs so that user be allowed to consume
applications they decided while others may permit to upload applications to
some configurable scope (e.g. apps that would be visible to all cloud
users, to particular tenant or be private to the user). We also think to
have some of peer relations so that it would be possible to have
application upload in one catalog to become automatically available in all
connected catalogs.

This is similar to how Linux software repos work - AppCatalog is repo,
Murano package is what DEB/RPMs are to repo and DSL is what DEB/RPMs
manifests are to packages. Just that is run on cloud and designed to handle
complex multi-node apps as well as trivial ones in which case this may be
narrowed to actual installation of DEB/RPM
