Is Migration Possible?
Monday, February 16, 2009 4

The short answer is
Yes
Monday, February 16, 2009 5

Is Migration Possible?
• Short answer is Yes?
• MySQL is enterprise ready
• 14 year old product
• Provides commercial support and indemnity
• Well established to deliver success on web
• Not just a web product
You interact with MySQL supported
systems every day

Marketing Examples

NASA
Application
Informing the general public on contract opportunities, managing large acquisitions on line
Key Business Benefit
Saves NASA and its partners $4 million annually
Catalyst to Migration Decision
Previous database vendor restructured its license program, causing NASA to be faced with
fees that were “more than twice the total annual budget”
Post Migration Results
- License fees were significantly lower
- MySQL averaged 28% faster, compared to other databases
- Running 3 years without any loss of data or down time
- “The cost of the optional technical support for MySQL was a fraction of that for the product
previously used”

Google
\"Google runs critical business systems
with InnoDB and MySQL. The systems
require 24×7 operation with minimal
downtime. The systems support large
OLTP and reporting workloads. We are
very happy with the scalability, reliability
and manageability of this software.\"

Embedded Deployment
• Easy not to realize where MySQL is in use
• e.g Support Systems
• Documentation
• Issue Tracking
• Publication
• Ad Tracking

Reasons
Monday, February 16, 2009 20

Reasons to Migrate
• Cost / TCO
• e.g. Subscription v License
• EOL H/W & S/W
• Integration into newer systems
• Asked to
• Forced to
• Physical resources
• Trend
Monday, February 16, 2009 21

Cost / TCO
• Truly difficult to value
• Software
• Hardware
• Support
• Skills
• Staff
Can you state your $ per customer investment
Monday, February 16, 2009 22

Cost / TCO
• Easy when starting a new project now
• Open Source
• Zero entry point - Licenses
• Zero entry point - Subscription (if desired)
• VC preferred
But
Monday, February 16, 2009 23

Cost / TCO
Less measurable incidentals
• Staff skills / proficiency
• Infrastructure
• e.g. H/W
• Integration points
• Reference material / procedures
Monday, February 16, 2009 24

EOL
• Newer H/W is significantly cheaper
• More verses Larger
• Growth, Redundancy, Co Location
• Existing licensing may be prohibitive
• Potential environmental impact

Going Green
\"We do worry about how to maximize
page views for kilowatt hours\"
Jim Buckmaster, CEO Craigslist
• Page views per kilowatt hour: The socially
responsible benchmark?

Monday, February 16, 2009 26

Integration
• Newer deployed systems for additional
purposes
• More efficient to retool old systems to
integrate with new
Monday, February 16, 2009 27

Acquisition
• Your company is acquired by another
with different technology infrastructure
• Not likely in Government situation
Monday, February 16, 2009 28

Forced to
• Management Decision
• e.g. \"No new nett Oracle licenses\"
• New government initiative ?
Monday, February 16, 2009 29

Physical Resources
• Newer languages being taught
• Desire to update skills
• New staff acquisition
• Off shoring / Outsourcing options
Monday, February 16, 2009 30

Open Source - Gardner
• By 2012, 80% of all commercial software will
include elements of open-source technology.
• By 2012, at least one-third of business
application software spending will be as service
subscription instead of as product license.
• By 2011, early technology adopters will forgo
capital expenditures and instead purchase 40 per
cent of their IT infrastructure as a service.

Monday, February 16, 2009 31

Open Source
• Sun releases Java
• Microsoft releases .Net components
• Adobe release Flex/Flash infrastructure
• MySQL, the 'M' of LAMP
• Be wary of different licensing
agreements for software reuse
Monday, February 16, 2009 32

Road blocks
Monday, February 16, 2009 33

Barriers to success
• Resource commitment
• Set expectations
• e.g. it works in Oracle it should work in MySQL
• It may be cheaper to migrate but it takes a
long time
• Fear of change
• Licensing/IP/Patents/Copyright
Monday, February 16, 2009 34

Actual Client Example
• Management directs use of MySQL
• Technical resources
• Refuse be 25%optimal numeric datatypes
to use
(could disk saving)
• Refuse to usein queries)indexes (improved
covering
performance
• Fudge in 15 sample SELECT's) full table
production simulation (3
scans
• Place junior inexperienced staffprocess
(in company
and technology) on evaluation
Monday, February 16, 2009 35

Summary
• MySQL can operate in the enterprise
• There are justifiable reasons to consider
MySQL
• Migration to MySQL is possible
• Opportunities, Technology and Time to
Market becoming more viable
