Rebuilding an acquired platform for Virgin Trains.

What they were up against

• Fifty-plus microservices and databases for a product at MVP stage.
• Cloud infrastructure costs far beyond what the product warranted.
• Weak SDLC practices and slow release cycles.
• Not enough engineering capacity, and gaps in security and performance.

What came of it

• 56% reduction in AWS costs, saving more than $476,000 a year.
• 34% increase in development velocity through architecture simplification.
• 7x faster testing and deployment.
• The capacity to execute the product roadmap at scale.

The work

Devtech engineers joined the internal teams rather than working alongside them, simplifying the architecture, bringing the infrastructure footprint back in line with the product, and putting a delivery process around it that the team could keep running.

Documentation, testing and deployment were rebuilt as part of the work, so the gains outlasted the engagement.
