Berkeley has been writing web services for the last 8 years, but they were not structured, not documented, not inventoried, not reviewed, and limitedly shared. They were done on demand, not part of a bigger plan. SOA is the next step for us. Our hope is SOA along with building a “Campus IT Community” and Campus Developer Support will enable a) FLEXIBILITY by allowing IT-by-composition, b) Composition over reinvention enabling SPEED, c) Thoughtful methodology, tool, and platform selection enable QUALITY.

From Services to SOA at Berkeley CSG - Sept 25, 2008 THE SOFTWARE GOAL: Quality, Speed, Flexibility. THE TRENDS: Increasingly complex and changing business processes. Increasingly tech savvy business partners. Increase dept/unit development of mission critical systems. Decrease in resources while increase in IT demands. THE CHALLENGE : How to get UC Berkeley from a set of unorganized, unstructured web services to SOA? We need help. We don’t have the right experience or enough of the right resources. Berkeley became Kuali Student Founder July, 2007.

We Got FIRST RATE Help CSG - Sept 25, 2008 UCB gave 2 of 4 Central App architects to Kuali... We benefit from the effort of 12 architects & several senior java developers. Of special note: Leo Fermin, UBC Scot Gibson, UMd Wil Johnson, FSU For the next phase we are looking for developers: At least 3 years Java experience (Sun Java certification an asset). Familiarity with Spring IOC and AOP. Familiarity with ORM concepts and JPA in particular (preferably the hibernate implementation). Advantageous if they have worked with Eclipse and SVN. Knowledge of XML, XSD, WSDL, SOAP.

From Services to SOA By Leveraging Kuali KS - July, 2007 Kuali Student is... Being developed through a community source process over 5 years. Will deliver through a Standards-based (open, widely accepted, adopted), Service-oriented architecture utilizing web services. Leverages Open Source Technology (Open source software stack & java). Modular and relies on Component Abstraction of Business Processes & Rules and Presentation & Data layers. Rules & logic will not be in code (use rules/workflow engines). Tier 1 Apps (first 5 years) include: Learning Unit Management, Enrollment, Person Identity, Student Financials, Program Audit & Evaluation, Limited Concierge, Application connectors, Configuration application Tier 2 Apps include: Admissions, Scheduling, Financial Aid, Concierge

SOA Challenges at Berkeley Semantic Interoperability – We don’t speak the same language (GPA, Student Registered/Enrolled, Chart String) Culture NIH (NOT INVENTED HERE)/NUMC (NOT UNDER MY CONTROL), Architecture/Technical Religious wars (.net/java, REST/SOAP). Business Processes Non-standard or Non-alignment (examples-UG & Grad Adm applic, grade submission) Funding and Resourcing Models Staffing New Skill Sets (BusAnalyst, SOA, UI experts, )‏ A fresh look Back Filling Key Positions BUSINESS ANALYSTS are rarer than we thought To succeed it is not about “central resources”, it is about “campus resources”.

SOA Challenges at Berkeley Immature Technologies - (Or did not live up to the vision). BPEL SOA is not about a Particular Technology - Processes SOA has a lot of pieces, development is in pieces - What will bring this all together? SOA is a different way to design systems - Loose coupling Loose coupling vs Performance – Example Enrollment - Communication Synchronous (Tight) vs Asynchronous (Loose) - Transactionality Two phase commit (Tight) vs Compensation (Loose) Implementation Readiness Governance Resources (Where are all the Business Analysts???) Interfaces New and Old Will the vendors get there? (Parviz Dousti– CMU) CSG - Sept 25, 2008

Biggest Challenge Getting out of our rut – Taking several steps back How we do our business. What are we really trying to achieve? How we develop our systems. How is a SOA system design different? Our new roles. Who does what? CSG - Sept 25, 2008
