Open Source or Commercial
Single or farm

Take the time to evaluate
Start with fewer features and
then introduce
Meet user expectations by
delivering only what you can
handle
Dynamic embedded features
can cause problems
If you don’t understand your
users don’t assume you do

Energize early-adopters, they are the core of communities
Grass-roots communication is powerful –
it places people at the center
Use multiple mediums to engage people in
an open public way
Empower people to participate in the open
to be exemplar contributors

WikiCentral for over 12 months barely kept up

WikiCentral in transition – the interim smart-routing design
12 WikiSym 2008 | September 8-10, Porto, Portugal © 2008 IBM Corporation 13. IBM Technology & Innovation
Things to consider when distributing wikis
Wikis need to be unique across all servers – it gives us freedom
– Wikis can be moved from server to server without issue
– Wikis can survive when we move to a high-availability cluster
Wikis servers need to route users to where their wikis are
– URLs will change, but users don’t
– Smart routing will ensure you always get where you are going
Smart routing services will be required to make these servers “one”
– Aggregated information are served from smart routing such as user
information, activities, and preferences.
13 WikiSym 2008 | September 8-10, Porto, Portugal © 2008 IBM Corporation 14. IBM Technology & Innovation
Smart-routing, high-available clusters makes it easy to do
more complex deployments
14 WikiSym 2008 | September 8-10, Porto, Portugal © 2008 IBM Corporation 15. IBM Technology & Innovation
Over time centrally located clusters can move closer to users
Employee’s shouldn't have to
visit Southbury, Connecticut
to get to their wiki.

Distributing the load unevenly turns out even better

In July, WikiCentral improvement paved the way for productivity
15x improvement in performance!
Slowest transaction at peek load now takes 1 second!

– Changes based on in-depth analysis of IBM’s wiki traffic patterns
– New deployment architecture and traffic distribution 210 wikis
– Added hardware/P5, upgraded middleware & tuning redistributed in
first week
– Currently deployed on 6 servers with 4 more to come 300,000 employees
– Distributing medium traffic wikis to allow for growth Over 22,000 wikis
– Continued analysis to forecast and manage future growth Over 400,000 pages

All things staying the same, WikiCentral performs
Wiki traffic does not follow typical patterns
Midsized wikis drive the most concurrent traffic
Before and after shows pattern stays the same
Before After
18 WikiSym 2008 | September 8-10, Porto, Portugal © 2008 IBM Corporation 19. IBM Technology & Innovation
The number of views to specific wikis stayed constant
Views increase after noon
because performance is
no longer a barrier to usage
Unique wikis used to be high
because the system was
unable respond fast enough
19 WikiSym 2008 | September 8-10, Porto, Portugal © 2008 IBM Corporation 20. IBM Technology & Innovation
WikiCentral response time is under a second and will improve
as we redistribute mid-sized wikis
Average response time
is under 1 second!

Summary
Choose the right software for your wiki situation
Take time to evaluate components and features
Energize early-adopters, they are the core of communities
Support your users with care – their success is shared with you
Build your wiki solution to meet your end-user's expectation –
scalability, functionality, and speed
