  3. About • Network is available in 173 countries. • Around 3,000 new customer sites every month • Carry 80% of all credit card transactions in the UK. • More than 90% of the UK’s financial institutions use our secure data networks • Rolling out super-fast broadband to 40% of the UK by 2012. • FTTC downloads of 40Mb/s and uploads of 2 Mb/s. • FTTP downloads of 100 Mb/s London 2012 Olympics

  4. Development Services Organisation • We advise on best practices for all tools • Inlife team looks after all hosted applications: • We are an Atlassian shop • Subversion, Jive Forums, Nexus • Other in-house tools • Authz, Teams, IPPI, Provisioning, Static Data & PALMS • SDK Catalogue (will soon become BT Enterprise Repository)

  5. Product History Dec 2003 • 5 people created a team (called code red) but there was no way of coordinating their efforts • Bought Confluence and Jira and installed it on a PC and put it in a meeting room June 2004 • Usage spread to a few development teams (200 users) • Bought new hardware and installed it in a server room (engineering.intra.bt.com) April 2006 • Another group installed a separate instance of Jira and Confluence to manage service improvements February 2007 • Management Services and Engineering decided joining forces would be a good idea • Userbase reached 300 and 2000 respectively • http://collaborate.intra.bt.com was born and hosted by VS Group on VMWare. July 2007 • A Virtual Administrator crew formed out of 35 volunteers from the userbase to perform end user support and administer the platform • Two users in particular did most of the Admin work. Userbase grows to over 9000 people.

  6. Product Maturity August 2007 • Sponsors found to pay for new hardware & uplift plan created • Team split started to disrupt progress to achieve this and ownership was contested September 2007 • Userbase grows to 10,000 October 2007 • I/O Capacity of the disks in the VSP environment started to be exceeded. • Platform started to have outages with huge traffic increase January 2009: • Moved to an enterprise hardware infrastructure, Oracle 10G RAC & 24x7 support • Collaborate Wiki was formed, Confluence 2.10 and integrated with Crowd February 2009: • Introduced Storm & Jira Issues July 2009: • Started to assimilate other wikis (like twiki, rdrwiki, ProfComms)

  7. Confluence Numbers • 800,000 pages • 102,000 attachments • 3000 spaces • 25,000 display requests per day • 30,000 actions per day • (eg login, edit, comments, rss feeds etc)

  8. Numbers • 3 flavours of Jira • ACF – Architecture Conformance Framework • Issue Tracking (100 projects) • Story Management Operating Model • BT is adding > 20,000 stories every month

  9. Confluence Use Cases • Tool Guides on how to get started • Tool Access Request Forms • We have a teams application we encourage before requesting a Space • Early stages of a Provision Application • Application Deployment Schedule • Collaboration between Dev and Inlife Teams (geographically dispersed) • Don’t send emails but rather send Confluence links • Trying to have an FAQ before raising an issue for help • Application Usage Statistics • MyBT has a dashboard interface and makes use of the Confluence remote API and render as html inside a portlet. • Most of the Ajax related actions don’t work

  10. Confluence Customisations • Implemented the functionality of security classification requirements in the scaffolding plugin. • To implement this functionality the edit page / do edit page actions of the confluence needs to be overridden. Scaffolding plugin was already overriding the edit actions of confluence. • Confluence doesn't allow two plugins to override a particular action. • Extended the edit actions to include classification

  11. More Confluence Customisations • https://collaborate.bt.com/staticdataplugin to provide a LOB picker from LDAP • Static Data Macro that retrieves platforms • BT Space Admin Confluence plugin makes use of our eorg DB in order to get the Line of Business functionality associated with a Space • Modified the Excel Plugin as it was hanging Confluence a lot • We had one user with a page that had 48 references to the excel macro • Every reference was an API call that forced a GC, so we disabled explicit GC • Page went from 14 minutes to load to about 4 seconds

  12. Customisations • Hierarchy plugin • Static Data plugin to strip LOB info out from LDAP • Loads of constraints on Story creation and workflow • All Stories must have at least one child and at least on Acceptance Criteria • Organogram • Added Active User Report under Users, Groups and Roles • Roles for Storm • Loads of different workflows (put issues On Hold whilst with Dev team or Vendor)

  13. More Customisations • https://collaborate.bt.com/fisheye plugin to allow the authorisation of SVN repositories (handled by hasPermissionToAccess method which is overrided to authorise against our Authz). • Use https://collaborate.bt.com/crowd client libraries for apps like https://collaborate.bt.com/forum • We have a Jira Project that helps us keeps track of Subversion Projects ensuring everyone has a Salsa ID. • Unified Rolling Calendar Plugin

  14. Application Monitoring • ZXTM • Nagios alerts via email for slow (or dead) apps. • JMX is enabled for most of our java apps • Disk space (e.g shell script to alert > 80%) • Backup successes or failures uploaded to our wiki • Access logs with IP tracking • Usage statistics to figure out what our users are doing • Perl script we run for snapshots of ugly apps • YourKit Profiling from within IntelliJ • kSar

  15. Platform • Currently 18 HP Blades mostly BL460s with 2 Quad cores and 32GB of RAM for our existing hosted application servers • RHEL 5 (soon OEL) • Were using Weblogic 10.3 but now Tomcat 6 • Java 6.0.18 • ZXTM 5.0 • Oracle 10g in a Cluster hosted by another team on HP Blade 680s with 2 Quad cores and 64GB of RAM • Crowd is our only clustered application (currently) • We use Capistrano to help automate our deployments and allows easy rollback

  16. What’s Next? • Clustering of Confluence, Jira and SVN • Triple our hardware for Disaster Recovery • Archiving & stats analysis plugins (customised) • Improve provisioning • All the Atlassian 2s (Bamboo, Crowd, Fisheye, Crucible) although upgrading to Fisheye 2.0 will be expensive on disk space. • Start charting long-term trends with better monitoring • Assimilate all wikis (like LimsWiki for one)

  17. Wishlist Confluence Wishlist • Tighter integration with Jira • Allow Jira Issues to be raised via Confluence and vice versa • Allow profiles to have attributes (like team, group or project) • Confluence attachment storage API. We want to store attachments away from Confluence and write our own adaptors to do this. • Improve the edit permissions cascading security • Customisations of actions (eg. Overrides to allow > 1 plugin) Jira Wishlist • Allow two columns for attributes • Allow picklists to show more values without scrolling • Smart forms that can include wiki macros • How can we hide Administrators from assignee list? • Can Greenhopper scale? How compatible is it with existing 3.13.2 plugins/customisations?

  18. More Wishes Jira … • Would like to use our Issues as a source for FAQ before users raise an issue? • Ought to be Confluence tightly coupled with Jira Issue labels • Timebooking to allow resource Management? Others • Fisheye 2 IE6 browser support • Make Crucible a viable app for the enterprise (we have some open Atlassian issues for 10k+ users) • Can we turn on “remember my login on this computer” checkbox during login?

  19. Lessons Learnt • Be wary of any plugin • Excel Macro plugin • We turned off the usage tracking plugin • We trialled the stats analysis plugin but its currently off since we got hammered two lunchtimes in a row shortly after going live • WebLogic seems to be a lot slower than tomcat • Confluence 3.x is much better than 2.x • We had problems with Crowd 1.6 client and currently use Crowd 1.3 client • Tune the JVM heap • Confluence: we use java –server –Xms:8G –Xmx:8G PermSize=512m MaxPermSize=512m +UseParallelGC +AggressiveHeapLargePageSizeInBytes=4M -DisableExplicitGC • Jira: we use –server –Xms4G –Xmx4G PermSize=1G MaxPermSize=1G +UseParallelOldGC +AggressiveOpts • Crowd: we use java –server –Xms:4G –Xmx:4G PermSize=512m MaxPermSize=512m • Fisheye: not really tuned yet –Xms:4G –Xmx:4G MaxPermSize=512m
