Our team just publicly published a white paper on how to use Watson Discovery on the IBM Cloud platform to create content collections and custom cognitive applications. It is related to the training tutorial I co-developed with colleagues at IBM but adds other best practices and business use cases. You can read this pdf here: IBM-Advantage-Paper-for-Cognitive-Discovery.pdf
Please give us feedback.

Complement Watson Conversation with Business Decision

Today I presented to IBM Reference Architecture team, with Guilhem Molines, IBM Operational Decision Management product architect, a new solution we are using during our consulting engagements that leverages the Watson conversation to gather customer's input and send to a decision service running in ODM. The solution is implemented as part of github.com (https://github.com/ibm-cloud-architecture/refarch-cognitive-prod-recommendations) so every IBM customers or consultants can study it.
Integrating chatbot in business applications, is definitively a trend started two years ago, and a lot of companies are still implementing solutions today. As part of the continuous improvement and optimization of the business operations, the next step is to use the data gathered during the conversation and apply business rules on top of it to deliver next best action or best recommendations. This will limit the human intervention to complex cases only, offloading the workload to rule engine.
To play with our solution you need an IBM Cloud public account, and the code and artifacts we developed to be able to run this solution. The solution integrates with [Decision Composer].
Have fun with this new assets and feedbacks are welcome.

Hybrid Integration starting to run on IBM Cloud Private

Hello, 
Do you want to get explanations on how to do hybrid integration with IBM Middleware products, cloud native app  running on public or private cloud?

The first hybrid integration configuration with cloud-native application (angular 4, nodejs/expressjs) is deployed on IBM Cloud Private, connect to API Connect running on premise, connected to IBM Integration bus to process an interface mapping flow, connected to a SOAP service to expose CRUD operations for inventory data source which runs on Liberty, and the data are persisted in DB2. 

You can see the light tutorial at this address: https://github.com/ibm-cloud-architecture/refarch-integration/blob/master/docs/icp/README.md 
Let me know your thoughts, and ideas

Friday, October 6, 2017

Next week the 10/10 is the IBM Cloud University in Berlin, a lot of good sessions will be presented on public and private cloud. I will deliver one presentation and two deep dive labs:

  1. Watson Discovery with weather collection: Reference. This lab was already presented internally to our technical staff in Dallas, London, Melbourne and Tokyo. The public web page tutorial can be accessed in the IBM Cloud Garage Method tutorial web site
  2. Watson Conversation to implement an IT Support chat bot (Reference): This is also a lab presented multiple times to our internal technical staff. The public web page tutorial can be accessed in the IBM Garage Method Tutorial

If you want to go over the hello world and access to some best practices to implement those solution, please come or visit those tutorials.

Hybrid integration with cloud native application

With the importance of cloud development, one major subject is to address how to integrate with existing assets running behind the firewalls. I am leading a new effort at IBM to deliver implementation validation covering integration between a angular 4 nodejs/expressjs app deployed as cloud foundry app or within docker container and integrating existing SOA service and on-premise database. The solution is open-source and can be downloaded from https://github.com/ibm-cloud-architecture/refarch-integration.

Multi Tenants in Decision Center IBM ODM 8.0.x

A friend and colleague today asked me a very good question so as I spent one hour on it, I think it makes sense to share the information with IBM ODM 8.0.x users.

The request is what are the best practices and governance approach to follow for supporting multiple 'tenants' in IBM ODM Decision Server? In Decision Server there are different user groups, each group may be responsible of multiple projects, but users in the group could not see projects of other groups.

Obviously this is supported by the product out of the box, but it is important to follow some practices.

First it is important to understand the synchronization architecture as describe in Synchronization architecture. As a long time best practice it is important to synchronize a rule project from Design to Decision Center (DC) when the BOM is stable, but in fact there is an alternate approach is to define empty project in Decision Center as soon as your development effort starts. The rule project name has to be defined as it represents the top synchronization point between Rule Designer and DC.

The first synchronization has to be done by and administrator role, as stipulates in Publishing projects to Decision Center: "you must have administrator rights to Decision Center to publish a project initially to it". This is logic as permission settings are done by super users once the project is in the rule repository. Basically a developer creates a rule project, with the final expected name, gives his workspace to an administrator, and lets the administrator creating the rule project into Decision Center and set the permissions. Let see how to do that.

The Decision Center needs to support different groups of users, with the constraint that users part of one group could not see other rule projects managed by other groups, and even administrator role within a group could not see other projects. There is only a super administrator of the Decision Center server. It is for example rtsAdmin. Most of the time you do not need to manage projects. You need user who may be part of the rtsAdministrators group and other group of users.

Suppose you have 3 groups of users defined in LDAP or WAS Federated Respository: UserGroup1, UserGroup2, and UserGroup3. (Use WAS admin console > Users &Groups management > Manage groups.

For each group define users with the Decision Center predefined role of 'rtsUsers' so they can login to DC and author rules. As in each group there is one administrator, for example Adam is part of UserGroup1 and has rtsAdministrator role, define the following group assignment.

This administrator is the person who can create projects in Decision Center for the first time. The table below presents an example of user allocations.

User Group Permission
Adam UserGroup1, rtsAdministrators Create rule project and set permissions
Bea UserGroup2,rtsUsers Author Rules
Eli UserGroup1,rtsUsers Author Rules
Val UserGroup2, rtsAdministrators Create rule project and set permissions

 Recall that to use Decision Center project security as well as its permissions mechanism, all groups (except rtsAdministrator) must be declared in both the application server and Decision Center. To do so use the Installation wizard: Configure > Administration. Installation Settings Wizard > Step 3: Setup Groups. Then use the New button.


Now suppose that each group has the following rule project ownership:
Group Rule Projects
UserGroup1 LoanApplicationValidation-rules, & LoanApproval-rules
UserGroup2 RiskAssessment-rules & DynamicTaskRoutingRules
UserGroup3 Pricing-rules

After synchronizing the first time the LoanApplicationValidation-rules rule project from rule designer

Adam (administrator of user group1), connects to Decision Center and sets the 'branch security' using UserGroup1. Configure > Security . Edit Branch Security. (Select 'Enforce and configure security..." toggle)


From now only users in UserGroup1 can access the ruleset LoanApplicationValidation-rules. Until the branch security is not set on a rule project, this project is visible by all rtsUsers or rtsAdministrators users. Therefore it is recommended to enforce security, as soon as a project is synchronized from Rule Designer to Decision Center. There is a time window when other users may see this project as part of the list of possible projects in the Home tab. This is not a problem if you follow the practice of creating a simple, mostly empty project.
As each project already presents in Decision Center has its security permission set, other users in other group do not see rule projects not controlled by his/her group.
