2. Moving the Open University to Moodle 2.1Ross MackenzieThe Open University

3. Starting Point Moodle 1.9 Lots of core customisations 770,000 users in database 176,000 users active on 559 courses 40,000 – 60,000 users per day Peaking at c.1.4M transactions per day (30 trans/sec)

4. Infrastructure Six webservers (4 student-facing, 1 admin, 1 housekeeping) Postgres database cluster (2 systems, active/passive pair) NFS cluster (2 systems, active/passive pair)

5. A typical day

6. A typical day – last Monday 1.16M transactions, 56.7K users, peak 30 trans/s

7. A typical year

8. Migration Targets Lose the localisations to core Rework OU-modules Demonstrate we can run M2 at scale Add cool new stuff

9. Where are we now… Localisations to core Very few in M2.0 / even fewer in M2.1 OU specific needs constrained to OU modules

10. Where are we now… Reworked/enhanced OU modules Forum / blog / wiki Quiz Authoring tools Dataplus Study Planner Subpage (resource page)

11. Where are we now… Running at scale / numbers 3M transactions in 24 hour period (using M2.0) 35 transactions/second Average transaction time 0.6s Modelled based on our most heavily used transactions

12. Where are we now… Running at scale / Infrastructure 9 web servers (+2,+2 ) – all virtual 6 students, 1 admin, 1 house-keeping, 1 stats 4 (2xstaff instance, 2xall students) Postgres cluster NFS cluster

13. Where are we now… Add cool new stuff Integration with Google Apps for Education Better mobile support Improved personalisation Annotation tool

14. Bringing M2 into service The OU never sleeps

15. OU patterns Lots of courses running to their own pattern Usage peaks in February, May and November Lots over 9 months, more 6 months long Migrate progressively at end of course Run Moodle 1.9 and Moodle 2.x installations in parallel

16. Parallel running Will keep current VLE running Current 1.9.11, 1.9.12 in Sept 2011 Expect to retain in service until end 2012 (?) New VLE Live to academic teams in August (using M2.1) Live to some students in late September

17. Issues / updated Performance Do now think this is going to be OK Accessibility We’ve made some fixes, M2.1 includes more Haven’t got Elluminate integration sorted out yet. Basic bridge available, does not meet OU needs

18. New Design Implementing new set of themes for M2 Wanted visual distinction between old and new platforms Building on experience with M1.9 themes

23. Mobile Matters Seeing increasing mobile device traffic to VLE Latest numbers c. 2.4M pages last month (to over 14,000 users) 58% Apple / 23% Android / 9% Blackberry

25. Annotation Tool Reinventing the highlighter pen and post-it note Make/manage annotations on any website Share annotations with other users (groups/OU/World) Follow other users
