What is the Cloud?
• Cloud is the idea of
working across the
network, where
applications and files
are hosted remotely
More than one path to get there
Why do you care about the cloud?

Types of Cloud computing
• Hosted services
– 3rd party hosts your data
and applications
– Microsoft hosted
exchange
– Gmail
– Rackspace web server
hosting
– Terremark data center
– Rent it
• Fog (local cloud)

Hosted services
• Pros
– No backup worries
– Reduces IT staff burden
– SLA (service level
agreement)
– Your IT staff cant screw it
up
– Mobility
– No upgrade problems
– Scalability
• Cons
– Recurring Costs
– Data privacy not
guaranteed
– Interoperablity issues
– Your issues will get
resolved at their
convenience
– Bandwidth is key!
– No internet, no service!
Rule of Thumb
• Hosted services requires adequate bandwidth
to the host, so calculate in the cost of internet
bandwidth requirements.
• Consider the no internet access scenario.
Examples of hosted Solutions

• High availability…can be costly to do it
yourself
• Backup generators, battery backups, load
balanced server farms, shared storage,
redundant storage, offsite backups…
• How much downtime can you tolerate?

Amazon Web Services crashed yesterday, taking
thousands of Web sites -- mostly
smaller startups -- with it.
The outage is now in its second day, and while the company says
service has
been partially restored and some sites like Reddit are back up,
others like Quora and Box Office Mojo are still offline.

Gmail outage passes 24 hours for some (updated)
By Seth Weintraub February 28, 2011: 1:01 PM ET A small percentage of people
have been without their Gmail accounts since Sunday.
Imagine if you lost your entire email inbox, sent box, folders –everything.
A small number of Gmail users logged into their accounts over the weekend to find
just that.
... Initially, the outage was said to have affected .29% of global Gmail users....
That was at 3:00 ET. Sunday. Since then Google has issued numerous updates
including a revised downward estimate of .08% of all Gmail users affected – which
comes out to about
150,000 users world wide. In the grand
scheme of things, that is very few, unless you are with out email today.

OPEN SOURCE ALTERNATIVES
• Open source software is:
– FREE of licensing costs
– Not quite as good but pretty close
– May have a steeper learning curve
– Less prone to viruses/ exploits
– Possibly less user friendly
– Makes transitioning to free operating systems easy
Rule of Thumb
• Using open source software where you can
may be an excellent cost saving measure. If it
doesn’t work out, you didn’t spend anything
on it…(just time and effort).
Are you an Excel Ninja?
• If you have a spreadsheet that does more
calculations than Einstein….You probably wont
like Open Office.
Open Source Free software
• Linux
– Your home router runs Linux
– Apache server (like IIS)
• Open office (Oracle/Sun)/ Libre Office
• FireFox browser
• Android (sort of)
Office scenario
Using the same office software for a 5 year life
span
Open Office = free, less user friendly, harder to
support, reduced functionality
Office 2010 = $280
Office 365 = $840
GET REAL! Or go Virtual?
What?
• Virtualization is replacing a
machine with a program
Why?
• When physical machines
die, recovery takes a while
• Virtualization frees you
from one application per
server
• Recovery becomes much
quicker
• Virtual machines can grow
as needs grow
Virtualization costs?
• Hyper-V (microsoft) $28 (or included with
your Operating system free)
• Citrix Xenserver (free versions, or paid
versions with automatic failover, and support)
• Vmware (free versions or paid versions with
automatic failover, and support 0-$7000)
Vmware VS Xenserver
Vmware is more fully featured
• http://blog.lanamark.com/2
009/04/price-comparisoncitrix-xenserver-enterprisewith-essentials-vmwareinfrastructureenterprise.html
Vmware is more expensive
Vm flexibility and scalability
Physical machines
• Each has own disk space,
ram and processors.
• Cannot share
• Cannot scale up
• Good resources get trapped
in an underutilized machine
Virtual Machines
• Can move from host to host
• Can be allocated more or
less resources as needed
• Reduce Air conditioning and
electrical costs
• Cloning
• Snapshoting
Hidden cost of virtualization?

Comlexity
Plan on additional training
Plan to have in house knowledge
You will need a SAN to leverage the full
Benefits of virtualization
• Initial Costs high for infrastucture to support
it, but saves money over time.
Rule of Thumb
• If you are looking for a free virtualiztion
platform, Xenserver has the most features
• All virtualization platforms are Linux based
(yes even Microsoft’s Hyper-V) so having Linux
skilled staff is a good idea
Virtualized workstations?
Pros
• Makes endpoint
maintenance free
• Endpoints for $300
• Data is secure in storage
• Image based, mass
produced, stays fresh
• Cross platform
• Can reuse/extend obsolete
workstations
Cons
• Up front cost
• Deployment complexity
• Storms of user activity must
be planned for
• not the best choice for
travelers, branch offices,
patrol cars, or locations with
poor internet service
Storage
SAN
• SAN- Storage area network
• iSCSI is much less expensive
than Fiber Channel, but not
as fast
• Think of it a huge hard drive
on it’s own network, that
many can share
• Large scale solution
NAS
• Network attached Storage
• Think of it a huge hard drive
across the network, that
many can share
• Storage traffic is in
competition with regular
traffic
• A smal l scale solution
Rule of Thumb
• Shared storage can save you money if you
have Large amounts of data (especially
redundant data)
• Average desktop cost for storage per user is
$120. You can use that number to calculate
• 200 users = ~$24000 in storage
San on the cheap
• We were able to implement a GB san over
existing fiber for about $4000 in network gear
• Our two 8 TB Storage arrays were about
$16000• This provides 8TB of storage that hosts all the
storage needs of the virtualization farm,
backups, and file server for 300 users. BUT,
they still have local hard drives ($120 each)
Advanced SAN features
• These features can reduce total storage size,
at a performance cost:
• Data Depulication
– Can reduce the total size of the storage by half or
more (great for storing backups and virtual
machines)
• Thin Provisioning
– Can allow virtual servers to share disk space
reducing the total storage size
Compliance
• Virtualization, centralized storage make it easy
to enforce records management retention
policies and ensure the data availability.
What type of organization are YOU
• Do it yourselfers? Highly trained staff with
customized software
• Microsoft penny pinchers? Small IT staff, still
trying to milk some life out of your old but still
useful stuff.
• Microsoft Early Adopter? Do you have your
own sharepoint site using InfoPath forms?
Do-it-yourself-ers
• If your IT department has people in IT who’s
job funcion you can’t fathom…this might be
you.
• You may do best with open source altenative
• Keeping things in house
• Invest in your staff and make sure they cross
train and document what they create.
Rule of Thumb
• If you have a highly customized environment,
especially if it’s based on open source
software, invest in your staff.
Microsoft Penny Pinchers
• If the start button on
your computer is gray
this might be you!
• You might appreciate
software ownership.
• Be sure to invest in
good 3rd party patching
and security systems.
• Expect migration
headaches.
•
Rule of Thumb
• If you are hanging on to old software, it’s a
good idea not to skimp on patching and
security software.
• Introduce open source solutions where you
can, to decrease migration headaches.
Microsoft Early Adopter
• If you are an early adopter of microsoft
technologies, Software Assurance and Office
365 might be good choices.
• You will have cutting edge capabilities
• Web apps are not the same as the desktop
apps , and require connectivity.
• Greater costs, fewer headaches?
