Enterprise Drupal SF State Presented By Kevin

Enterprise Drupal @ SF State Presented By: Kevin O'Brien w/ Supakit Kiatrungrit Division of Information Technology San Francisco State University nowarninglabel on drupal. org http: //www. coderintherye. com Greetings Drupal Ninjas Campus: San Francisco State University 1600 Holloway Ave. San Francisco, CA 94132 http: //www. sfsu. edu

Choosing Drupal Began with search for WCM for Do. IT Tested many (Plone, Open. CMS, Joomla, etc. ) Settled on Drupal for functionality and a 11 y Started w/ 1 virtual server, no real environment Started with 5. x and moved to 6. x Campus already had some Drupal exposure

Ancient History Portals required on CSU campuses • Project Approach (IBM Websphere) – – • Collaboration between SFSU Team and IBM Team Approach according to the established IBM Method An emerging consensus regarding portal development includes the following major best practices and considerations: – There should be one AND ONLY ONE horizontal portal on campus; – Portals should be developed

What happened previously • IBM Portal took years to implement base features. Required constant maintenance and time-consuming PMRs. • Other groups/depts. Didn't fully buy-in, saw IBM Web. Sphere as a “black box” • Project Manager/Maintainer left • Said hey “How about going to Drupal, they have it running successfully for WCM, would maybe take a couple months to switch”

IBM Lotus WCM vs. Drupal • Java • PHP • JDK/Java. EE/JSR 168/WSRP • drupal_hook API • Services module • Portlet Factory • Any IDE/Editor • Monolithic • • Broke weekly Core is relatively small • Few expertise • Huge community • No community • • Only support is PMRs Support via forums, IRC, Acquia

The A Team • Me – Architect / Developer / Themer • Supakit “superkid” Kiatrungrit – Developer • Bora Kou – Systems Admin (Part time on this project) • Jason D'Silva – Student Asst. Developer (10 hours/week) • Management position was actually vacant during our 2. 5 month sprint. So had a parttime interim project manager.

Scrum style agile development • What we liked: – Quick turnaround – Weekly feedback – – – Clear deadlines • What we didn't like: – – Scope creep – Cramming at end – Not enough time for testing/QA – Working a lot Daily checkins Learning a lot Loss of resources

Drupal & My. SQL Cluster : ( Drupal will not run out of the box on ndbcluster tables Problem: menu_router table and locale_sources tables A bug was filed with My. SQL, rejected because ndbcluster doesn’t support row lengths of that size Issues on d. o. filed to address this in core http: //drupal. org/node/391130 and http: //drupal. org/node/703916 Split the menu_router table into smaller, more manageable tables Remove the key reference on locale_sources or change the key data type to be something other than text/blob Workaround at http: //www. coderintherye. com/

Getting the Campus Community to Develop Offered two trainings – – – 1) How to install Drupal on your localhost 2) How to create Drupal modules 3) (Future) How to create web services Need hand-holding Monthly meetings and code workshops

How to get a Module (portlet) into Portal First content should be discussed with the oversight group before beginning development to ensure Portal is the correct place for it Some departments or groups may have a page in Portal that they are responsible for and control the content for All changes must go through the development cycle including unit and load testing Security testing of code (Plug for “Cracking Drupal”) Clean up and review of code

Development cycle Develop code • Run unit tests • Check into SVN • Additional development • Interface testing • Tag in SVN • Verify automated tests • User acceptance testing • Content is added directly here • Management approval • Automated tests run • If any tests fail, there is no push to production • Automated tests • If any tests fail, system is rolled back to previous build •

Prepare Define requirements including functionality and UI Remember you are working within the Portal template so many UI elements are predefined Define interfaces to backend systems The most common interfaces are REST/ Web. Services that should follow w 3 standards LDAP (V 3) Determine where portlet will be located and who should have access

Local development Build portlet Run unit tests Unit tests should include all UI components and all backend interfaces Check into svn Request dev build

Backend Work with the data and application owners of the source systems to build the required backend interfaces Make sure you follow the defined security model if there is one, or work with us to define one if the system you are connecting to has no model defined Set up web services

Development (DEV) Run unit tests Run integration tests, finalize development Peer review all code Tag SVN code for test Request Test build Code is pulled from SVN into Dev

Test/ Quality Assurance (TEST) Define test plan and execute all functional tests Tests must include all functions, UI components, and backend interfaces Perform user acceptance testing Perform load/performance testing Submit automated test suite for Staging and Prod This test suite must be comprehensive Make any content only changes directly in Test A manager must sign off indicating the following: He/she is aware of all changes going into production and approves them for the specified date The automated tests sufficiently cover all functionality All code has been peer reviewed The load/performance tests prove that the application meets the minimum requirements Tag code in SVN for roll out Code is automatically pulled from TEST at 1 am and deployed into staging

Staging Automated test suite is run If any tests fail, production roll out is not performed If all tests pass, promotion to Prod occurs automatically at 6 am

Production (PROD) Automated tests are run If any tests fail, production is rolled back to previous release

Accessibility 508 compliant All pages were run through manual checks Theme is color contrast compliant Testing out using the accessible_content module developed at CSUMB

Security IP based Access for back-end services Everything is behind a firewall Everything is behind Shibboleth auth Core PHP Module is removed Role based access to pages, panels Daily log checks (in future, archive logs in central change mgmt repository) Grendel-Scan OWASP standards

Scalability • We are not very big Handled ~500 concurrent users without problem • Peak ~5, 600 visitors/day • 357, 000 visits and 1. 7 million page views from March-May Shibboleth single-sign on & Google Analytics • Servers are way underutilized, use about 15% cpu on norm

Performance • Initial Build took 7. 5+ sec. Load times • Used Xdebug to find drupal_http_request was problem. Used cron to cache • Down to 3. 5 sec load times. • Installed APC via PECL (quite easy) • (Make sure to give it enough memory) • Down to ~1. 5 -2 sec load times. • Ensure Oracle db connects quit if can't reach (need to upgrade to 11 g)

Where we are Now vs. Where we want to be Now campus websites are fragmented, outdated Not all sites use Univ. Template, and some don't use it correctly or update it timely Depts want to move to central hosting We have a monthly meeting Drupal User Group Depts. want to put sites in centrally managed highly available Drupal install for easily keeping sites up to date 1 Drupal theme means a consistently updated look Need installation profile for point & click

Tools to consider • Aegir (still maturing when we looked at) • Open Atrium • Pressflow • Memcached/Boost • Cloud hosting via Acquia/AWS or Rackspace as well as consultants

Drupal is not the solution for everything (though I love it) Drupal is not – – our project management system (again Sharepoint) – our document management system (though it could be someday) We use Sharepoint our help desk ticketing sys (remedy, gia) It can be made to do all these things, but other products are out there
