What Am I Telling You Today?
• ‘Step change’ of Fitness First hosting and
development pipeline
• Manual to automation
• Standardisation ‘as the norm’
• Industry leading toolset
16 countries, 1 million members
• 24 x 7 x 365
The journey
Business Requirement
• Consistency
• Speed from concept to delivery
• Reduced cost
• Less errors
IT Strategy
• Industry leading toolset
• Standardisation of environments
• Automation
• Simplicity of process
• Less moving parts
• Transparency
The process
• Old, physical hardware
• Windows 2003, SQL 2005
• Bespoke toolset
• Manual, slow dev’ pipeline
• Old technologies
• Hyper-Converged hardware
• Windows 2012, SQL 2014
• Industry leading toolset
• Dev Ops process
• Modern technologies
The Challenge – A ‘Step Change’
• New technologies
• New skills
• Timescales
• Needed– A trusted partner
– Decisions and not 1,000 options
– The right toolset
What Is Now Delivered?
• Simplified
• Flexible
• Better TCO
• Faster
• Controlled
• Automated
The pipeline
The Database Problem
• “Regression testing 3 branches of code
across 16 countries – is easy right?”

Why?
• Reduce time-to-market
• Reduce overall cost of change
• Standardise processes across the
organisation
Challenges
• Multiple markets which require different data setup and config.
Maturity?
• Testing
Automated unit and acceptance tests, the latter written with testers. Testing part of development process.
Data Management
Database changes performed automatically as part of deployment process.
So maturity was good?• Level 3 – Optimizing: focus on process improvement
• Level 2 – Managed: Process measured and controlled
• Level 1 – Consistent: Automated processes applied across whole lifecycle
• Level 0 – Repeatable: Process documented and partly automated
• Level -1 – Regressive: process unrepeatable, poorly controlled and reactive
But….
• Integration, regression and feature
regression tests process was brittle.

128 databases!
Brittle?
• A single change to the database required
hundreds of databases to be patched.
• Impossible to track without tracing back to
the migration scripts that were normally
committed separately by the development
team.

A new way was needed
• A major change to the way Fitness First
build and deploy their software has been
the integration of Redgate's DLM
Automation Suite.
Source Control
• Took a backup of the production database
and put this under source control using
Redgate source control.
Continuous Integration
• Extended the build process to compile and
validate the schema using TeamCity and
Redgate's SQL CI
Release Management
• Deployments made with Octopus Deploy
and Redgate's SQL Release to the various
environments
Data
• Final optimisation was to have the data
under source control.
• Allowed us to seed the database with the
required data as part of the deployment
process for target environment.
The pipeline
The pipeline
Benefits
• Testers were no longer responsible for
making changes to database.bak files.
• Gave both developers and testers visibility
of the changes being made to the data in
order to support the tests
Benefits
• Gave us a single schema to build out
databases for the various environments.
• A single source to maintain
– Most importantly!
End result
