  2. None
  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
  14. 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>", …]

  18. Webserver Key-Value Storage Search FURY Frontend FURY Backend FURY Components

  19. Webserver Key-Value Storage Search FURY Frontend FURY Backend Legacy RDBMS

    Legacy System Session Storage Collect & Export

  20. Webserver Key-Value Storage Search FURY Frontend FURY Backend Legacy RDBMS

    Legacy System Session Storage FURY Requests 200 OK

  21. Webserver Key-Value Storage Search FURY Frontend FURY Backend Legacy RDBMS

    Legacy System Session Storage Requests to Legacy System 404 NOT FOUND

  22. Webserver Key-Value Storage Search FURY Frontend FURY Backend Legacy RDBMS

    Legacy System Session Storage Requests to Legacy System 404 NOT FOUND 200 OK

  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

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

    FURY Backend Webserver FURY Frontend Server B K/V Storage Search FURY Backend active = A

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

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

  29. RDBMS Read Slave Webserver FURY Frontend Server A K/V Storage

    Search FURY Backend Webserver (Router) Build Server Deploy Code active = B

  30. RDBMS Read Slave Webserver FURY Frontend Server A K/V Storage

    Search FURY Backend Webserver (Router) Build Server Deploy Code Collect & Export active = B

  31. RDBMS Read Slave Webserver FURY Frontend Server A K/V Storage

    Search FURY Backend Webserver (Router) Build Server Deploy Code Collect & Export Smoke Tests active = B

  32. RDBMS Read Slave Webserver FURY Frontend Server A K/V Storage

    Search FURY Backend Webserver (Router) Build Server Deploy Code Collect & Export Smoke Tests Switch to A active = A

  33. RDBMS Read Slave Webserver FURY Frontend Server A K/V Storage

    Search FURY Backend active = B Webserver (Router) Build Server Deploy Code Collect & Export

  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
