    1. 1. <ul><li>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. </li></ul><ul><li>SOA is the next step for us. Our hope is SOA along with building a “Campus IT Community” and Campus Developer Support will enable </li></ul><ul><li>a) FLEXIBILITY by allowing IT-by-composition, </li></ul><ul><li>b) Composition over reinvention enabling SPEED, </li></ul><ul><li>c) Thoughtful methodology, tool, and platform selection enable QUALITY . </li></ul>From Services to SOA at Berkeley CSG - Sept 25, 2008
    2. 2. 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.
    3. 3. We Got FIRST RATE Help CSG - Sept 25, 2008 <ul><li>UCB gave 2 of 4 Central App architects to Kuali ... </li></ul><ul><li>We benefit from the effort of 12 architects & several senior java developers. </li></ul><ul><li>Of special note: </li></ul><ul><li>Leo Fermin, UBC </li></ul><ul><li>Scot Gibson, UMd </li></ul><ul><li>Wil Johnson, FSU </li></ul><ul><li>For the next phase we are looking for developers: </li></ul><ul><li>At least 3 years Java experience (Sun Java certification an asset). </li></ul><ul><li>Familiarity with Spring IOC and AOP. </li></ul><ul><li>Familiarity with ORM concepts and JPA in particular </li></ul><ul><li>(preferably the hibernate implementation). </li></ul><ul><li>Advantageous if they have worked with Eclipse and SVN. </li></ul><ul><li>Knowledge of  XML, XSD, WSDL, SOAP. </li></ul>
    4. 4. From Services to SOA By Leveraging Kuali KS - July, 2007 <ul><li>Kuali Student is... </li></ul><ul><li>Being developed through a community source process over 5 years. </li></ul><ul><li>Will deliver through a Standards-based (open, widely accepted, adopted), Service-oriented architecture utilizing web services. </li></ul><ul><li>Leverages Open Source Technology (Open source software stack & java). </li></ul><ul><li>Modular and relies on Component Abstraction of Business Processes & Rules and Presentation & Data layers. </li></ul><ul><li>Rules & logic will not be in code (use rules/workflow engines). </li></ul><ul><li>Tier 1 Apps (first 5 years) include: Learning Unit Management, Enrollment, Person Identity, Student Financials, Program Audit & Evaluation, Limited Concierge, Application connectors, Configuration application </li></ul><ul><li>Tier 2 Apps include: Admissions, Scheduling, Financial Aid, Concierge </li></ul>
    5. 5. KS Services – Release 1 LUM <ul><li>* Authentication Service Learning Result Catalog Service </li></ul><ul><li>* Authorization Service LUI Person Relation Service </li></ul><ul><li>AZ Group Service LU Service </li></ul><ul><li>* Business Rules Management Service Organization Service </li></ul><ul><li>Communication Service Person Service </li></ul><ul><li>Contact Service Resource Service </li></ul><ul><li>Deprecated Service Descriptions Rule Repository Service </li></ul><ul><li>* Dictionary Service * Search Service </li></ul><ul><li>Fact Finder Service * Workflow Service </li></ul><ul><li>Learning Objective Service </li></ul><ul><li>* Business Agnostic Services, service contracts close to final, coding started. “Developers got anxious”. </li></ul><ul><li>** Service performance a concern so QA team has been working on enrollment service for Enrollment Module that has not be officially started. </li></ul>KS - Jan 1, 2008

    8. 8. SOA Challenges at Berkeley <ul><li>Semantic Interoperability – We don’t speak the same language (GPA, Student Registered/Enrolled, Chart String) </li></ul><ul><li>Culture NIH (NOT INVENTED HERE)/NUMC (NOT UNDER MY CONTROL), Architecture/Technical Religious wars (.net/java, REST/SOAP). </li></ul><ul><li>Business Processes Non-standard or Non-alignment (examples-UG & Grad Adm applic, grade submission) </li></ul><ul><li>Resources and Funding Models </li></ul><ul><li>Staffing </li></ul><ul><ul><ul><li>New Skill Sets (BusAnalyst, SOA, UI experts, )‏ </li></ul></ul></ul><ul><ul><ul><li>A fresh look </li></ul></ul></ul><ul><ul><ul><li>Back Filling Key Positions </li></ul></ul></ul><ul><ul><ul><li>BUSINESS ANALYSTS are rarer than we thought </li></ul></ul></ul><ul><ul><ul><li>To succeed it is not about “central resources”, </li></ul></ul></ul><ul><ul><ul><li>it is about “campus resources”. </li></ul></ul></ul>CSG - Sept 25, 2008
