2 The World We Live In The Internet of Everything Internet of Information 60T web pages (Google Index, October 2014) Internet of People 1.4B Facebook active users (December 2014) Image: Cisco Connections Counter Internet of Mobility Mobile devices account for 44% of all IP traffic (2013) Connected to 50B Things by 2020
3 2015 Tech Trends APPLICATIONS The Merging of the Real and the Virtual Worlds 1 Computing Everywhere 2 Internet of Things 3 3D Printing Intelligence Everywhere 4 Advanced Pervasive Invisible Analytics 5 Context-Rich Systems 6 Smart Machines IT for the Digital Business 7 Cloud/Client Architecture 8 Software-Defined Infrastructure & Applications 9 Web-Scale IT 10 Risk-Based Security & Self-Protection DATA Data Characteristics Volume Source Location Flow Frequency Diversity NETWORK Multiple layer 0 technologies required to address future needs Connectivity Cabling Infrastructure Source: Gartner, 2014
4 Producers and Consumers in the Enterprise Producers Applications generate data and/or results Services that connect collaborative producers Hardware and Connectivity are simply Enablers Consumers Utilize Applications and Services utilizing Hardware and Connectivity
5 Two Sets of Market Needs LAN (Services) Standards driven using commoditized technologies Installed base responding to current needs Modest growth tied to New construction IP Convergence Power-over-cabling WLAN POLAN & DAS Data Center (Applications) Rapidly transforming (and departing from LAN) Robust growth fuelled by More data Greater bandwidth Improved efficiency Cloud providers are changing the rules! Hotbed for new ideas, new technologies, new topologies Mature and conservative Dynamic and fast-paced
6 Applications Are Moving Cloud Shift Enterprise Data Centers Declining Data Centers Consolidating Bigger Data Centers Growing Economies of Scale Shift of Power & Influence
