Research from leading IT analyst firm Enterprise Management Associates (EMA) has evidenced strong and growing interest in cloud deployment models. While public cloud has gotten the earliest attention, stronger adoption is happening within private and hybrid models. In the EMA April 2014 report “Managing Networks in the Age of Cloud, SDN, and Big Data Network Management Megatrends 2014,” over 50% of respondents reported public/hybrid cloud initiatives were driving network management priorities. Since 2012, cloud projects have moved from early adopter status to mainstream business initiatives, and their impact on network management grew from 36% in 2012 to over 50% in 2014. These slides cover some of the insights from this new research.

8. Defining Cloud
For purpose of this survey, EMA defined cloud as follows:
Slide 8 © 2015 Enterprise Management Associates, Inc.
Private Cloud –
The private cloud infrastructure
operates solely for a single
organization and is managed
and hosted internally, inside the
corporate firewall.
Public Cloud –
The public cloud infrastructure
is provisioned for shared use.
It may be owned, managed,
and operated by a business,
an academic or government
organization, or some
combination of those
organizations. The cloud
service exists on the premises
of the cloud provider, outside
the corporate firewall. Public
cloud includes services such
as Amazon Web Services
(AWS), Microsoft Azure,
IBM/SoftLayer, and Google
Compute Engine.
Hybrid Cloud –
The hybrid cloud
infrastructure is a combination
of public cloud services and
an on-premises private cloud.
These systems are tied
together via APIs or other
proprietary technology that
enables data and application
portability between the two
systems, but they remain
separate entities. For
example, sensitive data may
remain on the private cloud,
but the applications or
services reside on an external
public cloud.

9. Survey – Primary Objectives
• Do performance issues exist across all
three types of cloud deployments?
• How are performance issues being
resolved across the various types of
cloud?
• Do traditional optimization methods have
a role to play in cloud?
• Are next-generation cloud-based
optimization solutions gaining traction?
Slide 9 © 2015 Enterprise Management Associates, Inc.

10. Survey – Secondary Objectives
• What workloads are being deployed
across the different cloud models?
• Are those workloads changing?
• How are cloud workloads being
monitored?

Since deploying to the cloud, which of the following benefits
have been met and which remain to be seen?
Achieved
Not Yet

56. EMA Key Takeaways –
Primary
• Despite pre-deployment testing, performance issues persist.
• There’s no “one size fits all” optimization solution.
• Workloads and cloud type matter.
• Traditional optimization technologies remain relevant, but next gen
cloud based are making headway.
• “Feature-rich” is not important — “Cloud-friendly” & “Best fit for
workload & budget” matter more.
• Cloud suffers from same monitoring, performance, and
manageability concerns as traditional deployments.
Slide 56 © 2015 Enterprise Management Associates, Inc.

57. EMA Key Takeaways –
Secondary
• Hybrid cloud workloads are increasing.
• Proprietary connectivity is giving way to less-expensive
public/broadband.
• Fixed networks are giving way to wireless ones.
• Mobile is the new enterprise desktop.
• Pre-deployment testing should include mobile devices and wireless
networks.
