  3. None
  4. None

  5. 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

  6. 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

  7. Finding a way out

  8. You don’t have to replace everything at once!

  9. What part of the software causes the highest amount of

    pain? • category pages • product detail pages

  10. Planning

  11. Current Setup Legacy System Session Storage RDBMS Webserver

  12. Idea Legacy System Session Storage RDBMS Webserver New Software

  13. None

  15. FURY Frontend Key-Value Storage getCategoryPage(341); "<html><head>…</head><body>…</body></html>"

  16. None

  17. FURY Frontend Key-Value Storage ["SBU06HE","TEOD3HE","ANW04HD"] Search search("{'category':341, 'filters':{...}}"); getTiles(["SBU06HE","TEOD3HE","ANW04HD"]); ["<div

    class="category-item">…</div>", …]

  23. Learnings • we have full responsibility now • no framework

    needed • no relational database needed

  24. 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)

  25. Deployment

  26. Webserver (Router) Webserver FURY Frontend Server A K/V Storage Search

    FURY Backend Webserver FURY Frontend Server B K/V Storage Search FURY Backend

  34. We are very close to launch!

  35. 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
