Increasing Reliance on Cloud Services Private Cloud/ Datacenter HQ Regional Offices Branch Offices, Remote Sites, Mobile Workers Cloud Apps/SaaS CRM ERP Internet Cloud Services Management Provisioning Security Applications like salesforce.com, Microsoft Office 365, Workday and other cloud-based applications have seen widespread adoption along with other cloud services, due to their virtually ubiquitous availability to allow employees to carry out important tasks without regard to time or place. It is a given that many of these leverage smart mobile devices and contribute to the mission-criticality of the network. These services have also helped bring cloud IT into the mainstream for a number of core technology functions and applications- enterprise IT is now more comfortable with the cloud. From Retail to Education to Healthcare, Enterprise IT is being challenged to provide mobile access to cloud-based business and consumer applications 2011 IDC Directions

Data Gravity Concentration of Data and Datacenters SP & Cloud Mobile Data App Data Public Data Implications of 'data gravity'. Major public cloud players are building up massive data stores (public, private, etc...). It will be ever harder for even the largest enterprise to resist the pull of these 'black holes' unless they become big data cloud players themselves. Most new Datacenters will be near cloud Datacenters

Cloud to Drive Bandwidth, VPN Services, WAN Optimization Adoption Q. What network/WAN changes have you made or do you expect to make in the next 2 years as a result of using cloud computing/IaaS?

The Many Meanings of Hybrid Cloud Q. Which of the following best describes the type of hybrid cloud you are currently using or plan to use? Subscription to multiple public cloud services from different cloud service providers for different business needs Subscription to multiple services (cloud, managed hosting, colocation) from a single service provider An IT environment that uses a mix of public cloud services and on-premises private cloud A mix of public cloud services and an off-site, service provider-hosted dedicated/private cloud An internal datacenter environment that supports multiple vendors' hypervisors Use of public cloud services and private/dedicated cloud resources to support the needs of a single distributed applications Management of all cloud resources using a common orchestration platform, with centralized resource provisioning automatically © IDC Visit us at IDC.com and follow us on Twitter: @IDC

Rise of Software-Defined Networking Software Defined Networking (SDN) is emerging as a new architectural approach to networking in the cloud era Decouples network control plane from data plane, establishes clear abstractions for automation and programmability, resulting in agility. Integrates well with major cloud-management platforms Can drive OPEX savings in large data centers through automated network provisioning, configuration Started within the Datacenter, but now being used to address WAN and Inter- Datacenter connectivity needs for: Agility Flexibility Improved App experience © IDC Visit us at IDC.com and follow us on Twitter: @IDC
