10. Mobile Apps for Enterprise
BYOD Becomes Prevalent Model
Mobile Apps for Enterprise
Strategic focus shifts to SaaS and mobile apps
SaaS and mobile app market size increases 200% ($27B to $80B) by 2015
By 2015:
15 billion network-connected devices > two for every person on the planet.
the average U.S. citizen will have seven connected devices
40% percent of devices used to access business apps are personally owned
75% of enterprises now have "bring your own device" policies in place.
Cisco’s Visual Networking Index Forecast
IDC 2011
Aberdeen Group 2011

11. its no longer possible to manage the device its all about the apps

12. Apps are the new endpoint
Must be designed to scale
Micro-Apps means hundreds of apps
Thousands of users
Different policies for different constituents - roles, departments, geographies, etc.
Many different types of Apps
Native mobile apps
New and existing web apps
In-house developed apps
Apps sourced from third party or SI
Commercial off-the-shelf apps

Password = cowboys
Information goes clear text
Anyone can see it
SSL/TLS encrypts the data using a certificate
The certificate is a unique credential identifying the owner
A certificate Authority authenticates the identity of the certificate owner.

21. Congestion – optimizing for TCP backoff behavior
Shaped high-priority traffic
Asymmetric return data
Data congestion is usually asynchronous -- outbound
Generally if utilization is above 40% the link is congested
The more compression the better
Need to shape traffic
Congested low-priority data
