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 Monday, February 16, 2009 6

Marketing Examples Monday, February 16, 2009 9

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” http://mysql.com/news-and-events/generate-article.php?type=ss&id=nasa Monday, February 16, 2009 10

The Weather Channel • Software & Hardware overhaul • Reported • 30% increased capacity • 50% decreased cost • Sun Solaris to x86 commodity H/W & Linux • Websphere to Tomcat • Oracle to MySQL http://mysql.com/customers/customer.php?id=22 Monday, February 16, 2009 11

Google quot;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.quot; http://www.innodb.com/innodb/users/ Monday, February 16, 2009 12

MySQL Migration References http://mysql.com/why-mysql/migration/ • White Papers http://mysql.com/why-mysql/white- papers/mysql_wp_oracle2mysql.php http://dev.mysql.com/tech-resources/ articles/migrating-from-microsoft.html • Customer Migrations http://www.mysql.com/customers/?migration Monday, February 16, 2009 18

MySQL Migration References • This workshop • Migration Overview • Migration Products • Migration Partners • Ideal Candidates • Roadblocks Monday, February 16, 2009 19

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 Monday, February 16, 2009 25

Going Green quot;We do worry about how to maximize page views for kilowatt hoursquot; Jim Buckmaster, CEO Craigslist • Page views per kilowatt hour: The socially responsible benchmark? http://blogs.zdnet.com/BTL/?p=3434 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. quot;No new nett Oracle licensesquot; • 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. http://gartner.com/it/page.jsp?id=593207 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 Monday, February 16, 2009 36
