Comparing and Justifying On-Premises
Workload Costs Versus Public Cloud Costs
What is Rightsizing?
CloudPhysics provides enterprise customers with unprecedented levels of private
cloud visibility and data-driven analytics. The insights gained allow these customers
to make intelligent costing decisions based on actual workload consumption of such
resources as CPU and storage. Customers can quantify and extend resource usage
and associated operational costs (OpEx) across the data center or down to a single
virtual machine (VM). These granular details allow direct comparison of on-premises
costs to public cloud costs, which helps customers make the smartest cloud
migration decisions.
Today’s Challenge
Customers running a private cloud or virtual platform are challenged to understand
their environmental OpEx costs in determining whether a move to the public cloud
will save money. Executives request cost comparisons and justifications for workload
migration. Additionally, IT must justify OpEx costs to avoid budget cuts. Without a
clear understanding of these workload costs, IT staff must rely on vague justifications
for either keeping workloads on premises or moving them to the cloud. Lacking
definitive costing knowledge, IT managers can only turn to industry averages and
vendor stories, making for a less-than-informed decision.

Make the Case: Justifying Cloud Migration
Before migrating to the cloud, an organization needs to understand the cost benefit
of the undertaking. Customarily, cloud migration requires understanding of both
current on-premises hosting cost, and the potential cost of their workloads in the
cloud. Cloud providers may do an excellent job of communicating both the cost and
“potential savings” of their services. However, without knowledge of actual costs, any
savings remain elusive and unspecific.
Figure 1: The CloudPhysics Cost Comparison App
CloudPhysics solves the process of analyzing the current environment and applying a
costing calculation to workloads. Granular analytics help customers identify accurate
private cloud costs and use a true “apples-to-apples” comparison of these same
costs on the public cloud to reach an informed decision about the financial sense of
a move.
Even with a per-workload costing model, customers still want to make the most
advantageous decisions about provisioning their workloads. CloudPhysics makes
recommendations for rightsizing workloads according to resources actually used.
Rightsizing prevents customers from needlessly over-investing in those resources
in the cloud, further reducing the cloud opportunity cost and maximizing public
cloud savings.

3. Plug the power supply-to-chassis connector cable (provided) into the DB-15 connectors located at
the rear of the power supply and the chassis.
4. For redundant power supply configurations, repeat these steps for the additional power supply at
the other side of the power supply tray.
Note. The switch does not provide an on/off switch. Instead, the switch powers
on when a power cord is plugged into the power supply’s front panel and
plugged into a power source.
Do not connect to a power source until all power supplies and power supply-to-
chassis cables are installed and the switch is ready to boot.

Taps vs SPAN
Taps: The Clear Winner
When it comes to visibility, your first line of defense is access to data.
You have two choices: Taps or SPAN.
Network taps provide the details that SPAN ports don’t.

NETWORKS ARE GROWING FASTER THAN EVER.
In 2015, Gartner estimates there are 4.9 billion connected Internet
devices, with that number expected to grow to 25 billion by 2020.*
This means exponentially more and more complex traffic.
When complexity goes up, visibility needs to go up. You need to see
EVERYTHING in your network. In other words, you need to see...
TAPS DON’T CHANGE OR ALTER DATA, INTERRUPT
DATA FLOW, OR STRESS THE SWITCH.
ALSO, TAPS PROVIDE SCALABILITY, MEANING...
SPAN MEANS LOST DATA AND FEWER
SWITCH RESOURCES.
ALSO, SPAN IS NOT SCALABLE, MEANING...
As traffic goes up...
Taps provide effective visibility by letting you see 100% of network traffic. SPAN ports obstruct your network monitoring and leave you vulnerable.
SPANTaps
access to all data is maintained. As traffic goes up... visibility goes down.

Device Switch
Ixia taps sit passively inline and provide ALL the data to
monitoring devices.
SPAN ports can result in packet loss and, because they
require port mirroring, take away valuable switch ports.
In today’s network FOREST, you can’t miss the TREES!
