Kuali Rice: Enterprise Middleware Solutions

Geoff McGregorTerry Durkin

Quick Review Kuali Rice – middleware suite of integrated products Kuali Nervous System (KNS) – application development

framework Kuali Enterprise Workflow (KEW) – document routing engine Kuali Identity Management (KIM) – identity and access

management services Kuali Service Bus (KSB) – common registry of remote

services Kuali Enterprise Notifications (KEN) – broker for university-

related communications

Bundled Rice Bundled Mode

When you download KC, you are downloading Rice

By default, Rice is Bundled with KC

Behaves as one monolithic application All services in local Spring

context Web content in the same war Single DB schema

Standalone Rice Rice can be downloaded separately and run as an

independent service Standalone client integration options

Embedded Remote Hybrid – different modes by module

Changing Integration Modes KC was designed to make switching deployment modes

relatively simple kc-config.xml:

Modify <module>.runmode parameters If using embedded, specify the Rice datasource info Ensure dev.mode param = false If using KSB security, fill in keystore params Modify rice.app.url to point to the Rice webapp url

Embedded Mode Rice services run in the client application and access the Rice DB directly Independent Rice web app and database

Embedded Mode Fast – embedded client talks directly to the database Scalable – processing load is distributed No need for application plugins on the Rice server to

handle application-specific logic

Remote Mode Client applications interact with Rice standalone via KSB service calls or

straight web service calls

Remote Mode Loosest coupling Easy to connect May require multiple deployment artifacts

(app + plug-in) Reduced performance due to transport

overhead

Modular Design Each module composed of a set of service interfaces and API

components Each module also has a reference implementation of those

services Each module publishes services on the service bus that are

available externally Services are located and invoked – they may be deployed locally

or remotely and the caller does not need to know Client applications code to the module APIs – don’t care about the

underlying deployment mode

DocumentService documentService = ServiceLocator.getDocumentService();documentService.routeDocument(myDocument);

Resource Loaders Modularity powered by the resource loader stack A component in Rice which locates and loads references

to service endpoints All services identified by a qualified name Can also load objects from classloaders

Resource Loader Stack

Kuali Service Bus Sits at the bottom of the Resource Loader Stack Simple service bus Exporters Connectors Synchronous service invocation Asynchronous reliable messaging Service registry

Kuali Service Bus

KSB Service Registry

Kuali Service Bus Provides the ability to scale applications horizontally Can publish more than one service with the same name

from multiple instances KSB will round-robin requests, as well as fail over if an

instance is down KSB can identify which application cluster a service

belongs to based on app’s Service Namespace

eDocLite Part of KEW Build simple forms quickly Ideal for quickly turning paper-based forms into electronic

forms back by workflow and its features: Document search Action list Email notifications Route log Routing rules

eDocLite Created with XML and optionally javascript

No java, no relational tables – data stored in a table by key-value Data can be transformed and inserted into relational tables via

postprocessor hooks, if necessary Even ‘lighter’ (but more limited) than KNS Maintenance

Documents

eDocLite

Putting It All Together

Putting It All Together As an enterprise middleware solution, Rice provides:

Common development framework for programmers and experience for users

Generic workflow engine can be leveraged by any application Consolidated action list, doc search for all KEW-enabled eDocs eDocLite for quickly building lightweight routable eDocs Centralized, comprehensive identity management solution KEW and KIM synergy for group and role-based routing Communication broker for system-to-system integrations (e.g.,

KC-KFS)

Rice at IU - Architecture Load balancer with four clustered Kuali

Rice standalone server instances Use Tomcat as the servlet container Shared file system mount for attachments Oracle database Many client applications use an

embedded workflow engine This is our recommended integration model

There are a few “thin client” applications remaining which utilize plug-ins

IU Kuali Rice Architecture

Scalability Designed for horizontal scalability Load balancer helps to distribute

requests Could add additional application servers

to suit needs Over the years have moved from two

application servers to four to handle increased usage

Using embedded workflow engines also helps to distribute the load

KIM Integration Identity management at IU is handled by a

separate team Use a tool from Microsoft called “Identity

Lifecycle Manager” Provisions identity data into KIM database tables Does so in as near real-time as possible

Implemented a custom SOAP service and published on the KSB to receive CRUD operations

Also integrates with Active Directory for groups

KIM Architecture

Enterprise Portal Our Enterprise Portal is currently using a

“closed-loop” version of the service bus to handle communication between different instances in their application cluster

Action List portlet Notifications Channel Future projects:

Bringing portal onto the enterprise bus Loading student calendars via web services KIM Integration

Enterprise Portal

Problem Solved! Created a multi-page form to collect all

disclosures Faculty with nothing to disclose can simply

submit the form after filling in some info For those with disclosures, cut the processing

time from up to two months, to within a week No more data entry costs – staff can work on

other things Reporting:

Send reports to departments Run reports to determine who still needs to disclose Metrics

Research Administration – Conflict of Interests

Research Administration – Conflict of Interests

For those faculty with no disclosures, they can select all “No” and they are finished

If “Yes” is answered to any question, it takes them to a screen where they can enter disclosures
