The Phoenix Project
One of the most powerful things that IT can do is get environments to development and QA when they need it
• IT bottlenecks• Setting Priorities• Company Goals• Defining Metrics• Fast Iterations

Database Cloning Challenge
If you can’t satisfy the business demands then your process is broken.

Tradeoff: Speed, Quality, Cost

What We’ve Seen
1. Inefficient QA: Higher costs of QA2. QA Delays : Greater re-work of code3. Sharing DB Environments : Bottlenecks4. Using DB Subsets: More bugs in Prod5. Slow Environment Builds: Delays

4. Subsets : cause bugs
![Page 15: UKOUG, Instant Cloning: Boosting Application Development](https://reader038.vdocuments.site/reader038/viewer/2022102923/54c6ed0e4a7959be1e8b45ce/html5/thumbnails/15.jpg)
Production4. Subsets : cause bugs
Classic problem is that queries that run fast on subsets hit the wall in production.
Developers are unable to test against all data
The Production ‘Wall’
