3 Services: At the Center of Growth Everyone s doing it already Most plan to do a lot more Driving most budget growth 80% of US companies are at least considering Public or Private using enterprises expect to increase their spending by 34% over the next 24 months Businesses will spend $122B on Public IT services in 2018 Developers 90% of new commercial apps now developed specifically for cloud Enterprise & Service Provider IT infrastructure spending to build/enable cloud services are growing at 20% per year, reaching $65B in 2017 Arms Dealers Service Providers By 2020, more than 40% of all servers will be in Service Providers data centers up from 19% in 2014 (most of expansion from cloud) Source: IDC View Survey 2014, Public Tracker, December 5, 2014, other IDC resources,

4 Insights: How Does Figure into Enterprise IT Sourcing Plans? Provider Site: 52.9% Customer Site: 47.1% [Q3] Please estimate what percentage of your organization s total annual IT budget is allocated to each of the following procurement/management models. Traditional Outsourced (eg., Application Management) 21.5% Today External : 31.4% Virtual Private 5.5% Traditional In-house 36.4% Public 19.5% Dedicated Private 6.5% In-house Private 10.7% Traditional Outsourced (eg., Application Management) 21.5% In 24 Months External : 40.8% (29.8% growth) Virtual Private 10.8% Dedicated Private 12.0% Traditional In-house 27.5% Public 17.9% In-house Private 15.7% Provider Site: 56.8% (7.5% growth) Customer Site: 43.2 Public cloud is transformative and challenges all our notions about how IT is bought, staffed, operated, and capitalized Private cloud is evolutionary for the vast majority of enterprises, and the likely onramp to cloud for the next 24 months Hybrid approaches to IT delivery are already a standard, but cross-platform management is the next frontier Source: IDC View Survey 2014, n=2378 worldwide IT respondents 4

5 Networking Analogy to 3 rd Platform First Period (1980 to 1995) -- ARPANET, Circuits, Hubs, SNA, Ethernet, Token Ring, Routers Mainframes and Minicomputers Second Period ( ) -- Switching, Multiprotocol Routing, LAN-WAN, TCP/IP PC/client server, with predominance of north-south traffic Third Period (2010-?) -- The SDN/DDI Era, DevOps/NetOps, Hybrid, 3 rd Platform Apps For virtual workloads and workflows, big data, hyperscale web, VMs, containers east-west traffic predominates, focus on automation, programmability, orchestration IDC Visit us at IDC.com and follow us on 5

10 What s Driving Today s SDN Deployments? Q. Which of the following factors is the primary motivation for considering or implementing SDN? Need the network to have more agility to support virtualization applications/cloud 29 Increase ability to deliver new applications or services across the network 23 Require better programmability of network for operational efficiency (OpEx gains) 21 Increase speed of provisioning the infrastructure for application workloads 12 Scale the network to support various and growing workloads 8 Simplify moves, adds, changes and decommissions Use SDN to lower CAPEX (initial investment costs) % 5% 10% 15% 20% 25% 30% N=228 Source: IDC's 2014 SDN Survey, April 2014 IDC Visit us at IDC.com and follow us on 10
