Scalability & Flexibility
Scalability
Start small, Grow as per needs
Add capacity by throwing more HW resources
VM based, Multiple VM per blade
Flexibility
Separate Data & Control plane

Post Deployment Tasks
Conventional Solution
Mojo
Needs to be managed at every site
Easier as there are fewer number
of sites
No comprehensive network view in
multi-controllers environment
Why ?
Centralized EMS needed to get this
view making it cost dominated feature
Single pane view of the network.

high availability design

Why ?
Country to Floor granularity with
Mojo Navigator
High Level requirements of cloud managed massively scalable
deployment model
Centrally managed, Single Pan of glass visibility
Start small, Grow as per requirements
COTS hardware for servers
AP Hardware at factory cost
Fully redundant – Highly available
Green deployment, Low footprint
Zero Touch deployment
