Defining Cloud

For purpose of this survey, EMA defined cloud as follows:


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.

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?


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

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.


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.
