Origin of Cloud A TIMELINE OF SERVICE DEVELOPMENT…
Possible Origins of Cloud ◦ The sixties with ARPANET and J.C.R. Licklider
◦ Scientist John McCarthy – offered up that computing should be delivered as a public utility, like a service bureau (also coined during the sixties)
◦ Salesforce.com in 1999
◦ Amazon Web Service in 2002
March of 1999 – Al Gore invented the Internet!
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 18
Origin of Cloud AN OPINION PAGE…
Cloud has been well socialized as a service model… Smartphones and Tablets have provided users at all levels of an organization the experience of:
◦ Having an application for most anything you need
◦ Having access to it with the click of a button (and perhaps $4.99)
◦ Application functionality that is upgraded regularly (automatically)
◦ Your data is always there when you need it
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 19
Cloud Impact! EXPECTATIONS FOR SERVICE CONTINUE TO GROW
People Expect: ◦ Network Connectivity, anywhere, anytime
◦ There’s an App for that!
◦ It’s just expected to work, both uptime and functionality
◦ Security is expected
◦ What does it take to deliver these applications, these services?
WHO CARES!?!
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 20
IT Perspective THE PAST
Traditionally we had to understand and run the infrastructure, IT Teams therefore must worry about:
◦ Network, Servers, Storage, Desktops
◦ Now Wireless, Voice and Collaboration
◦ Backups, Capacity Planning, Performance Optimization, Disaster Recovery
◦ Implementation of new applications or upgrades
◦ Customization for special requirements
Users, however, only care about getting to their data and applications!
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 21
IT Perspective THE FUTURE
Cloud typically comes with large components of the required infrastructure baked in:
◦ Core Network Components ◦ Servers and Storage ◦ Connectivity and Security ◦ Backups, Capacity Planning, Performance Optimization, Disaster Recovery
and more…
Users STILL care most about getting to their data and applications
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 22
IT Perspective THE PRESENT
Understand and be a forward thinker. As-a-Service means just that, and companies are moving to it at a high rate of speed because:
◦ There is real value in the model.
It’s not just the economies of scale on the hardware, it’s also: ◦ The process of procurement being greatly reduced
◦ Design, development and implementation being simplified
◦ Less effort required for ongoing management of these environments
◦ IT Disciplines are inherent in the offering – Backups, Capacity Planning, Performance Optimization, Disaster Recovery and more… are built-in!
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 23
IT Perspective THE FUTURE IS DEFINITELY IT-AS-A-SERVICE
If you’re not ready to investigate the value of cloud computing for your firm here are some steps you can take:
◦ Don’t let any vendors talk to your firm without first screening them
◦ In particular, NO CONSULTANTS!!!
◦ Make sure that any staff augmentation folks stick to the work at hand
◦ Be watchful of what trade rags your firm receives
For the non-adventurous among us, these are dangerous times!

Business Perspective
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 25
THE PROMISE OF NEW TECHNOLOGIES
Cloud technology advances help organizations…
◦ Supplant their traditionally complex environments
◦ Utilize more agile, elastic and scalable frameworks
◦ Create a more productive workspace and core IT
infrastructure
Business Perspective
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 26
THE HEADACHE OF PROGRESS
Understandably…
◦ Many organizations and CIOs don’t know where to begin
◦ It is an overwhelming prospect to revamp one’s workspace or core
infrastructure that has served them well for years
◦ Making sense of a vast vendor landscape adds to the confusion, as
does the difficulty in articulating a business case for change
◦ Managing the migration to cloud can be time-consuming, disruptive,
difficult and expensive
Business Perspective
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 27
THE RISKS!
With so much at stake…
◦ Can CIOs rely on Cloud to support their firm’s business objectives?
◦ Will Cloud really provide needed improvements or simply add to the complexity of your IT environment?
◦ Will these changes impact user productivity or worse, impact the functionality of the applications your firm relies on?
◦ With the pace of change in Cloud technologies how can you be sure that the investments made today will offer long-lasting value?
Business Perspective PRESSURE FROM ON-HIGH!
C-level Executives and Owners are definitely interested in IT-as-a-Service: ◦ They read the trade rags, they talk with their peers
◦ Even the notion of such benefits stirs real and justified business interest
◦ More organizations are proving its value everyday
Keep in mind most firms won’t leap into the cloud: ◦ Walk before you run
◦ Start doing your homework now, create that long term strategy
◦ Get the advice of people with actual experience

Technical Overview:
Examining the Platforms
Top Three Cloud Platforms TODAY’S CLOUD ALREADY ENABLES A MIXTURE TO BE USED
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 37
Hypervisor Evaluation OPINION – NOT FACT…
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 38
Hyper-V – Microsoft’s virtualization platform. ◦ Build on modified Xen Architecture
◦ Hyper-V 3.0 making significant inroads in the private data center
◦ Adoption in Cloud computing is still limited
◦ Hyper-V with Windows Datacenter offers a one-and-done license model
◦ Datacenter brings virtual Windows servers and integrated management with Microsoft System Center easing the deployment, administration and management of this environment.
Hypervisor Evaluation OPINION – NOT FACT…
8/26/2013 A PRESENTATION ON CLOUD COMPUTING
39
Citrix Open Source Xen Hypervisor ◦ Runs some of the largest clouds in existence (Amazon/Facebook)
◦ Minimal software costs with robust enterprise and cloud features
◦ Supported versions of Open Source, Xen and Cloud Stack
◦ An extremely scalable platform
◦ A favorite for Linux workloads but just as functional for Windows
◦ Truly the platform big cloud has been built on to date
Hypervisor Evaluation OPINION – NOT FACT…
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 40
VMware vSphere – The original Virtualization platform ◦ The gold standard in the datacenter (IBM of virtualization)
◦ Additional features and acquisitions have rounded out its Cloud capabilities
◦ Cost has been a significant deterrent to wide-scale adoption
◦ For virtualization there is no better product out there
◦ For Cloud, VMware is still playing catch-up
Note: as new orchestration tools arrive on the scene it will enable VMware‘s virtualization abilities to be better utilized as a Cloud platform.
A Quick Comparison MEASURING UP – VIRTUALIZED SERVERS
vSphere is purpose built for virtualization
Hyper-V and XenServer both rely on general purpose OS’s (Windows & Linux) for basic hardware functionality
This tends to give VMware a performance edge.
1) VMware 2) Citrix 3) Microsoft (just an opinion)
This will soon change over time…
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 41
A Quick Comparison MEASURING UP – VIRTUALIZED DESKTOPS
Traditional Servers are high RAM, Sporadic CPU
Desktops are the opposite, heavier on the CPU
VMware‘s CPU thread management lacks a little when it comes to high rates of context switching
Hyper-V and Xen, because of the CPU assignment, tend to perform much better in this space
Latest XenServer is seeing 500 desktops per host
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 42
A Quick Comparison MEASURING UP – TOOLS, MANAGING YOUR ENVIRONMENT
Virtualization and Cloud are NOT THE SAME
Cloud relies on virtualization but it is much more than that
To extend virtualization across multiple locations maintaining the look of a single realm requires more than a stack of hosts, it requires orchestration – aka Cloud
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 43
A Quick Comparison MEASURING UP – TOOLS, MANAGING YOUR ENVIRONMENT
VMware & Citrix have commercial Cloud platforms
Microsoft focus – Private Cloud, no orchestration
VMware vCloud Director – vSphere support only
Citrix – Support XenServer, Redhat KVM, vSphere and is expected to support Hyper-V by Q1 2014
Multi-platform orchestration simplifies migrations of data/configurations
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 44
Technical Overview
Examining the Tools
Tools! THE RIGHT TOOLS – A KEY INGREDIENT FOR CLOUD
vCloud (Vmware) and Cloud Platform (Citrix) provide orchestration for each layer
OpenStack is an option, many flavors = challenges
Stick with a major vendor for now, keep in mind this is for a mature organization, not needed when you start to Crawl or Walk with Cloud
Private Cloud is typically overkill for one Firm
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 46
Tools! THE RIGHT TOOLS – A KEY INGREDIENT FOR CLOUD
But if you are leveraging full Cloud…
Multi-vendor orchestration means options for the right hypervisor, storage and networking workloads
A Cloud advantage = breaking away from proprietary stacks, a commodity approach to compute services
Technology in this space will change rapidly over the next few years, being agile and flexible is critical.

Putting Cloud to Work:
Where to Start
A Utility Service CRAWL OR WALK BEFORE YOU RUN!
Look at the common prebuilt services…
Desktop-as-a-Service (DaaS)
Backups-as-a-Service (BaaS)
Disaster Recovery-as-a-Service (DRaaS)
Fileshare-as-a-Service (FSaaS)
Storage-as-a-Service (SaaS)
8/26/2013 ©2013 MCPC, INC. CONFIDENTIAL & PROPRIETARY 49
Your Application on IaaS CRAWL OR WALK BEFORE YOU RUN!
Pick a very Independent Application…
One that is as standalone as possible
Data is self-contained
Interactions with other applications is minimal
On your first pass, make sure you are building the road to integration with your infrastructure
8/26/2013 ©2013 MCPC, INC. CONFIDENTIAL & PROPRIETARY 50
What to Watch Out For…
IaaS – Service First IAAS WORKS BEST WHEN SERVICE MAKES A DIFFERENCE
Don’t just move your hardware to the Cloud
Your problems won’t change when you simply fork-lift compute and storage to the Cloud
Utilize “As-A-Service” Services!
Providers are already experiencing hardships when strong services don’t match the good platform they are offering
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 52
Information Management CLOUD IS THE ULTIMATE IN APPLICATION & DATA DISTRIBUTION
Understand the impact on data management…
Make sure you OWN your data
Make sure you have easy access to your data
Look for APIs that allow you to connect transactions
What is needed to interact with the Cloud systems for functional modifications?
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 53
Gotcha’s A FEW QUICK WARNINGS
Licensing – it’s not the same in the Cloud
Adjust for metering - encryption negates de-duplication, increasing your data requirements
Bandwidth is important, don’t underestimate
Understand the impact of performance on users
Get a long-term strategy
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 54
Gotcha’s WALK, JOG RUN…
You Want This…
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 55
Gotcha’s WALK, JOG RUN…
Not This…
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 56
Common Misconceptions
Common Misconceptions DO NOT TAKE CLOUD FOR GRANTED…
It’s Easy - It’s Easier ONLY IF you have aligned the particular cloud service with the appropriate business needs
Care Free - Remember your Responsibilities in IaaS
Elasticity is over-emphasized for IaaS – size up cloud for what you are using/need, elasticity is a feature you will use occasionally
It’s Secure – Not so, try Hybrid Cloud to reduce risks
It Performs Well – Check the stats on your provider! Test It!
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 58
Summarizing Cloud
The Value is Real! FIND IT!
Look to these areas for real value:
Procurement: Hardware & Software Licensing & Maintenance Costs
The normal design, build and deploy process
Your IT Disciplines: Backups, DR, HA, Capacity Planning, etc…
Ongoing Administration and Support
Project Management Throughout
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 60
The Value is Real! ONCE AGAIN – WALK, JOG THEN RUN
Consider using a Utility Service as a starting point
For IaaS Use an Independent Application first round
Hybrid Cloud with a known vendor gives you the flexibility that is needed when you begin using compute and storage as a service
Start looking to understand your Long Term Strategy as soon as possible
8/26/2013 A PRESENTATION ON CLOUD COMPUTING 61
Cloud is a Paradigm Shift FOCUS ON AS A BUSINESS STRATEGY, FOCUS ON SERVICE
Cloud is a change in business strategy
As-a-Service means trading in complex mixtures of IT components and process with Service
