Choosing a right software can be confusing
Scalability
Flexibility
Customizability
Performance
Single or farm
Open Source or Commercial

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 — enables employees to share information without process or technology know how
Support fast, simple and effective website management
Provide self-service team collaboration spaces
Facilitate true community-based encyclopedic authoring
Over 22,000 wikisOver 400,000 pagesOver 300,000 users

Content management
Team & project management
Collaborative authoring
Employees are using wikis in different ways

Your community’s behavior influences your strategy
With over 1,000 new wikis created per month
An ever increasing database and file system
High volume diverse trafficOver 300,000 employees
Viewing over 1,000 wikis per hour
Averaging over 20 views per wiki
Managing over 330 GB of data

It makes sense to distribute to loadMultiple instances
Geographically distributed
Clustered Over 300,000 employees
Viewing over 1,000 wikis per hour
Averaging over 20 views per wiki
Managing over 330 GB of data

WikiCentral for over 12 months barely kept up

WikiCentral in transition – the interim smart-routing design

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.

Smart-routing, high-available clusters makes it easy to do more complex deployments

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
300,000 employeesOver 22,000 wikis
Over 400,000 pages
Data collected on July 3, 2008
15x improvement in performance!Slowest transaction at peek load now takes 1 second!
15 miles / hourFast sprinter
219 miles / hourFast sports car
– Changes based on in-depth analysis of IBM’s wiki traffic patterns– New deployment architecture and traffic distribution– Added hardware/P5, upgraded middleware & tuning
– Currently deployed on 6 servers with 4 more to come– Distributing medium traffic wikis to allow for growth– Continued analysis to forecast and manage future growth
210 wikis redistributed in
first week

All things staying the same, WikiCentral performs
Wiki traffic does not follow typical patternsMidsized wikis drive the most concurrent trafficBefore and after shows pattern stays the same
Before After

The number of views to specific wikis stayed constant
Views increase after noonbecause performance isno longer a barrier to usage
Unique wikis used to be highbecause the system wasunable respond fast enough

WikiCentral response time is under a second and will improve as we redistribute mid-sized wikis
Average response timeis 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
