This document summarizes key aspects of cloud computing. It begins with a brief history of cloud computing and an overview of the three main types of cloud: public cloud, private cloud, and hybrid cloud. It discusses factors to consider when determining what type of cloud is appropriate for different needs. The document provides examples of business migrations to the cloud and discusses important planning considerations like security, connectivity, and managing the migration process. It aims to help organizations understand the cloud and determine if and how it could benefit them.

1. Uncovering the Cloud
Steve Knutson, Chief Technology Officer

2. UNCOVERING THE CLOUD
• History of the cloud (short)
• Is it right for everything and everybody?
• Considerations and planning
• Examples
• Q & A

3. THE CLOUD
• What do you think of when you hear
the word “Cloud”?
• The cloud has been around for a long
time
• When we walk back through history –
main frames and dumb terminals were
the first cloud

4. Centralized Decentralized Centralized
HISTORY OF THE CLOUD

5. • Delivery of computing as a service
• Shared resources and information
• Provided as a utility
• Think electric service
• Delivered over a network
THE CLOUD DEFINED

6. WHY CARE?
• Changed how we store
information and access
applications
• Shifting how we “buy” technology
• Driven by connectivity
• Where did the term “Cloud” come
from?

7. 3 MAIN TYPES OF CLOUD

8. PUBLIC CLOUD
Cloud provider…
• Owns hardware
• Responsible for the maintenance and uptime
• Typically houses equipment
Why choose…
• Can reduce complexity
• Can decrease lead times for implementation
• Usually paid for with operational funds

9. PRIVATE CLOUD
Internal or enterprise cloud …
• Deployed over an internal network
• Located on-premise or collocated (CoLo’d)
• Company usually owns equipment
• Managed with corporate staff or third party
Why Choose…
• Can be paid as capital or operational expense
• Usually best performance
• Can be easiest to secure

10. HYBRID CLOUD
Combines power of public and private clouds
• Integration can be expensive
• Payoffs generally worth it
Why choose…
• When not all applications work in public cloud
• When it’s economical to achieve integration

11. BENEFIT BREAKDOWN
PUBLIC PRIVATE HYBRID
Pay for tech as operational expense X X X
Reduced Implementation costs X X
Highly scalable X X
Easy to manage X Some
Easy to upgrade hardware and software X some
Fast patches and security fixes X Maybe
High secure X Some
High performance Usually Some

12. MOTIVATIONS FOR MIGRATION
• Easier mobile access
• Anywhere, any time, from any device using cloud provider’s infrastructure and
bandwidth
• Business agility and flexibility
• Pay as you go
• Better analytics on application usage
• Delivered to you from cloud provider
• Includes software licensing compliance
• Reduced and/or re-allocated costs
• Can remove some of IT’s greatest non-value-adding challenges
• Focus on mission critical initiatives

13. KEY CONSIDERATIONS
• End Users
• End result should show similar or better performance
• May require them to change and get training
• Don’t “push” technology to them
• Business buy in
• Need sponsorship from the top
• Is the financial model of “purchasing IT as you go” right for the business?
• Opex vs. Capex
• Architecture
• Will it work?
• What applications work best?

14. COMMON CONCERNS
• Security
• Moving your data and applications to a third party provider creates some security
risks
• Loss of control
• The control of hardware, software, security policies, etc., is placed in the hands of a
third party provider
• Integration
• Having multiple systems communicate with each other can be a challenge
• Connectivity to cloud resources
• More discussion to come

15. MIGRATION ROADMAP
1. Assess your applications and workloads
2. Address security and privacy requirements
3. Build the business case
4. Develop the technical approach
5. Adopt a flexible integration model
6. Manage the migration

16. WHEN BUYING “A CLOUD”
1. Spend time on connectivity
• Most failed deployments are due to poor connectivity
• Fall short of 100Mbs (LAN speeds)
• Consider an SD WAN connection (next slide)
2. Know your Service Level Agreement (SLA) or Service Level Target
• Best efforts vs. guaranteed – who’s responsible
• 99% uptime may not be enough for your organization
3. Take an extended test drive
• Conduct a pilot with a group of users (PoC)
• Not everything always works as advertised

17. SD WAN
• More network control using software and
automation
• Pay less for more performance
• Rely more on public broadband and less on
private links
• More efficient way to send and retrieve
information based on traffic types
• Not easy to implement
• Significant programming and talent required
• There are upfront hardware requirements

18. MANAGED WAN
• Monitor vs. Guard
• Red and green lights
• With Managed WAN…
• Respond to the “Yellow Light”
• Technicians can remote in and make changes
• Uses Data Collection Agents to collect
statistics and potential problems
• Automation is the future
• Does many tasks automatically – but not all

20. PRE-SALES
• Pre-sales workbook

21. EXAMPLE BUSINESS MIGRATIONS
The good, the bad and the ugly
• Business situation and goal
• Many small offices and remote users
• Data center is a closet (literally)
• Server is end of life
• Sounds like a perfect fit for public cloud;
• Except they have a home grown line of business app that won’t work
• Solution
• Hybrid Cloud with LoB app remaining on premise, all other apps in public cloud

22. • Business situation and goal
• 100 users on older laptops and desktops
• Do not want to manage or purchase new hardware
• Just bought new servers
• Sounds like a perfect fit for some sort of cloud and co-location
• Solution
• Move new servers to public cloud provider’s data center (CoLo)
• Have cloud provider manage servers
• Configure DaaS, or terminal services to utilize existing laptops/desktops
EXAMPLE BUSINESS MIGRATIONS
The good, the bad and the ugly

23. • Business situation and goal
• Wanted Opex spend for technology
• Did not want to manage equipment
• All applications tested in virtual environment
• Sounds like a perfect fit for public cloud
• Discover poor performance compared to previous on-premise solution
• Solution
• Multiple Internet connections with SD WAN

The good, the bad and the ugly
