Part I : Cloning Technology

Part II : Agile Data Acceleration

Database Cloning Challenge

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

QA and UAT

First copy

Production

• CERN -  European Organization for Nuclear Research

• 145 TB database• 75 TB growth each year• Dozens of developers want copies.

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

“if you can't measure it you can’t manage it”

1. Inefficient QA: Long Build times

Cost ToCorrect

Software Engineering Economics – Barry Boehm (1981)

3. Full Copy Shared : Bottlenecks

Frustration Waiting

Old Unrepresentative Data

4. Subsets : cause bugs

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’
