HOW WE GET RID OF OUR MONOLITH DON’T

How we started • built on top of a standard
e-commerce platform • a lot of custom code to support a wide combination of product options Feature X Feature Y Feature Z Core Code Customization
The challenges of a growing business • serious performance issues
• own developers don’t feel comfortable with the code • adding individual features is too complex • upgrading is hard
Finding a way out
You don’t have to replace everything at once!
What part of the software causes the highest amount of
pain? • category pages • product detail pages

Learnings • we have full responsibility now • no framework
needed • no relational database needed
Goods and Bads • fully object-oriented • easy refactoring thanks
to 100% code coverage • not enough automated acceptance tests • dependencies to legacy software (database changes, API calls)

We are very close to launch!
What next? • party hard! • identify the next pain
points we want to work on • replace the next parts of the legacy system with new, self-contained components / services
