2. About Me Adam Anderson @SQLPioneer sqlpioneer.wordpress.com
My name is Adam Anderson, and I have been a database developer for over 10 years and in IT for more than 20. I am MCSA certified and will be taking my final test in a month or two to get my MCSE.
So I have a friend that is a financial accountant and he always droned on about ROI and how most people didn’t understand it. When I asked what he meant he told me that if you invest 100,000 dollars and a year later you get 12,000 dollars in return that was a 12% ROI and most companies would take that and run. However, if you can start making a 1000 dollars a month it is still the same money

4. The Value of Change

5. The DevOps Promise Increased Return on Investment
Stability and Reliability
Improved defect detection
Reduced deployment risk
Better Audit Records

6. Return on Investment

7. Small Units of Work
Deliver Working Code Faster Reduces Risk Easier to Test Quickly Identify Problems

8. 100 X 15 X 5 X 1 X Cost of a Defect Production Manual Testing Coding
Design

9. Redgate ROI Calculation
Developers Salary (65$ Per Hour)
The cost of Introducing Software
The Savings Gained
The $ Value Realized
((Total hourly savings * hourly cost)
– Cost of introducing software) * 100
Cost of introducing software
The ROI of Database DevOPS
Average US developer = 100,000 * 30% for benefits / 2000 hours a year = 65$
Training Time + Software Cost
Savings Gained

10. Example ROI Calculation
Developer Cost $65 Per Hour Cost to Introduce Process 80 Hours * $65 + Software Licensing = $21,130 Saving Gained 60 Minutes Reduced to 10 Minutes 4 Times a Day 833 Hours Saved Annually * $65 = $54,145 Return on Investment $33,105 = 156%

19. Database Deployment Types

20. Deployment Types
Migration Based
State Based

21. State Based Deployments
Create build artifact
Compare artifact to destination
Create script to modify destination
Run Script on Destination

22. Migration Based Deployments
Create Script to migrate data and schema from current state to future state
Run all scripts necessary to upgrade to current version

23. Advantages and Drawbacks
State Based
Handles code merges Better
Acts more like OOP code
Migration Based
Handles working with data better
Code merges can be more difficult
Both
Hard
