Solution: Murano App Catalog
Get, Share and Run Apps on Demand
Create Catalog
● Easily add new apps
● Describe forms, app
dependencies, suggested
configurations, billing
rules etc.
Deploy Apps
● Deploy applications and
services with a push of a
button
● Choose apps, specify
settings, and deploy
Automatically
Manage Apps
● Monitor with Ceilometer
● Automatically self-heal, scale
up & down, failover, backup
● Application specific actions
● Track usage
Utilized by the OpenStack Community App Catalog

6. Hybrid Multi-Cloud Auto Scalable
Infrastructure Application.
Goal : Demonstrate a Hybrid Multi-Cloud Auto Scalable Infrastructure, using Murano
app catalog based enhanced Kubernetes and OpenVPN applications.
Murano-deployable OpenVPN, Kubernetes applications from App catalog.
Secure VPN connectivity between Private and Public cloud compute services.
Metrics driven approach to Auto (Elastic) Scale Up or Down of compute nodes in
Hybrid cloud environment.
