MYTH BUSTERS Know the Cloud.
MYTH BUSTER NO. 1DATA SECURITY
“A cloud provider cannot guarantee security.”
From a physical standpoint, public cloud datacenters are amongst the
most secure premises on the planet. Yet, at the logical level, a cloud
provider with every security certification still can't guarantee the integrity
of specific servers, applications, and networks, if your applications are
poorly written, set up and secured.
Here's where the IT Pros remain squarely in control and critical to cloud
success. All the security practices of a cloud provider are meaningless if a
customer organization's security practices are weak.
FACT:
MYTH:
The essence of cloud services is flexibility. One application may call
another on a different cloud service, and data may be stored anywhere,
including your own network, but still be accessible to cloud applications.
No cloud provider offers a service that completely takes control of your
environment. The best cloud solutions will be a combination of on and
off-premise services.
FACT:
“My organization will
be locked into one
vendor and lose
control of its data, if it
moves to the cloud.”
MYTH:
MYTH BUSTERNO. 2DATA CONTROL
“My company must move all its applications to a cloud
service to be able to benefit fully from cloud computing.”
Moving an entire datacenter to the cloud is nearly impossible. Nor is it
recommended by any cloud provider. Start by identifying applications in your
pipeline that can benefit your organization by being in the cloud. Look for
applications where resources are used intensely for a short period each
month then left idle for the rest of the time, or applications where a
moderate level of resources are used continuously, but experience periods of
very high activity.
These applications are good cloud candidates, because the cloud can scale
up and down resources on demand. The cloud is built for flexible access to
resources that can be allocated to other applications, or even other
customers, when idle.

MYTH BUSTERNO. 4PRIVATE CLOUD
Your company can benefit from a private cloud. The points to remember when
talking to business management about a private cloud is that you still own
everything: hardware, software and, even uptime management accountability. This
means you have to manage the infrastructure and the capacity requirements to
meet internal SLAs just as you do today. An on-premise private cloud is still a
CapEx expense, in contrast to cloud assets operated by a provider like Microsoft.
To realize the benefits of a private cloud, the projected savings from the increased
utilization of your existing infrastructure must outweigh the incremental cost of
building that cloud. An alternative is to opt for a hosted private cloud, in which a
hosting provider maintains the hardware; it allows you to cut your capital
spending and move it to Opex.
FACT:
My company can
get all the
benefits of cloud
computing with
a ‘private’ cloud
running on our
own hardware.

MYTH BUSTERNO. 5JOB SECURITY
“If my organization deploys Microsoft Online Services
my role as an Exchange Administrator goes away.”
The role of the Exchange Administrator does not become obsolete due to
the cloud. There are still many tasks that remain on-premise. You still
have to manage your users and their mailboxes. Industry-specific data
retention compliance, as well as implementing custom workflows, is still
your responsibility.
While some tasks may no longer reside on-premise, managed cloud
services free up your time to engage in more strategic roles, providing
you with new opportunities.
FACT:

MYTH BUSTERNO. 6IT ROLE CHANGES
IT Pros become more essential to their organizations when opting to use
public cloud services like Windows Azure. Windows Azure facilitates
moving some applications off-premise to the cloud. But, apart from
patching those servers and physically maintaining them, all other aspects
of managing applications remain in the IT Pro's hands.
Monitoring, updating, integration with services such as Active Directory,
security and network monitoring - these task are still required within
organizations utilizing cloud services
FACT:
If my organization uses
a public cloud service
like Windows Azure my
role becomes less
technical.”
MYTH:
MYTH BUSTERNO. 7VIRTUAL MACHINE = CLOUD
“If I'm running applications or network services on
virtual machines, I'm already doing cloud computing.”
Just having VMs doesn't mean you have launched a cloud computing
environment. Yes, you are on the road to cloud computing, but are
not yet reaping the full benefits. A VM must provide the ability to
grow or shrink ‘compute and storage capacity’ on the fly in order to
deliver service comparable to a cloud computing resource.
You also need to have the ability to provide pay-as-you-go pricing to
the departments in your organization to approach the cost-savings
afforded by the cloud's on-demand services

MYTH BUSTERNO. 8CLOUD TYPES
There are many types of cloud. For example, a "customer cloud", is a
private cloud hosted on-premise. A "partner cloud" is another variation of
the private cloud that is hosted by an outsource partner.
Finally, the "public cloud," a loosely connected network of web and
application services, is the most discussed variation of cloud computing,
yet it involves a level of service that no providers actually deliver today.
What IT Pros must take into account as they consider any cloud service is
the availability of standard and familiar protocols and application stacks.
FACT:
There is only one
kind of "cloud."
MYTH:
MYTH BUSTERNO. 9INTEGRATION
Integration issues go away when applications
are outsourced to the cloud.
No. IT teams dedicated to application compatibility and
integration play a big role for their organizations, just as they did
before the cloud. While some stand-alone applications can be
moved independent of other existing systems, many will require
integration with on-premise as well as other cloud applications.

MYTH BUSTERNO. 10BENEFACTORS OF THE CLOUD
The benefits of cloud computing apply equally to all
businesses. Many companies are making big bets on the cloud
today. Microsoft itself has 40 million users of its Online
Services, including large and small organizations. Also, 10,000
corporate customers are using Windows Azure, such as 3M,
Siemens and T-Systems.
FACT:
Only a small business can
gain any cost savings
benefit out of Cloud
Computing.
MYTH:
MYTH BUSTERNO. 11GETTING STARTED
All you need is your credit card to start cloud computing.
You can begin using cloud computing services with just a credit card. This is
a good way to get experience with this new frontier of services. Most cloud
services provide an environment designed for getting started and
developing applications. In most cases, the cloud providers offer a ‘Getting
Started’ level of resource for free. Microsoft does, for example.
FACT:
MYTH:
MYTH BUSTERNO. 12JOB OUTLOOK
Organizations may look at the cloud as an opportunity to save on hardware and
software costs. However, any potential savings are jeopardized by the elimination of
the IT Pro’s role. There will still be a demand for skills in the security space, network
management, integration skills, Active Directory and infrastructure management.
The IT Pro’s role will evolve as the availability of compute cycles and networked
storage increase – that is a given, just as the IT role has evolved in the past. The
question IT Pros must ask themselves is, ‘am I prepared to play a more strategic role
in my organization?’
FACT:
The IT Pro’s
role goes away
with cloud
computing.
