Cloud: A Strategic/Key Resource For Nearly 80% of Respondents

Q. Which of the following best describes your organization's view of cloud computing/IaaS?

N=504Base: currently use OR plan to use cloud computing for IT infrastructureSource: 2014 IDC U.S. Enterprise Communications Survey

A strategic part of our IT environment moving forward

Another IT resource that we will use as part of our portfolio

We will take a wait and see approach on how best to use cloud

We don't understand how cloud computing/IaaS could be used by our

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?

N=413Base: Datacenters UsersSource: 2014 IDC U.S. Enterprise Communications Survey

Increase bandwidth

Buy a higher quality network service

Use a class of service mechanism

Change network service providers

Use cloud services over a VPN instead of the public Internet

Use WAN optimization

No changes as a result of using cloud services

Management of all cloud resources using a common orchestration plat-form

Public and private/dedicated cloud resources for a single app

Internal datacenter environment w/multiple vendors' hypervisors

A mix of public cloud services and off-site, hosted dedicated/private cloud

Mix of public cloud services and on-premises private cloud

Mix of hosting/colo/cloud services from a single service provider

Multiple public cloud services from different cloud service providers

Q. Which of the following best describes the type of hybrid cloud you are currently using or plan to use?

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

Essential Guidance Workloads are driving new requirements across the entire

spectrum of IT Infrastructure – radiating out from the datacenter to the WAN• Take an application-centric view of IT Infrastructure to see how

workloads are delivered; look to automate where possible

• Optimizing web-site performance continues to be a key requirement

WAN Application Delivery and Cloud Load Balancing will be the “Engine” of Hybrid Cloud

As complexity grows, be aware of increasing need for cloud infrastructure orchestration, visibility, management and automation, across vendors and cloud providers• Cloud and disaster recovery/business continuity are having major

impact on datacenter/IT operations and strategy
