As OpenStack matured and began reaching the upper layers of the Cloud stack, a number of OpenStack projects started working with cloud applications. Soon enough several initiatives emerged to build services which would provide various catalog-like functionality for these apps. The most notable of these initiatives are project Murano, an Openstack big-tent project officially known as "Application Catalog for Openstack", project Glare (aka GLance ARtifact REpository, previously known as Glance v3) and a Community Application Catalog, an initiative backed by Openstack Foundation, hosting some cloud apps at apps.openstack.org.
This talk will provide the answers to the questions above, dot the i's and cross the t's on differences and similarities of these projects, explain why they do not compete and demonstrate how the combination of them may help application developers to succeed in delivering their apps to end-users.
