Help Merative prioritize your ideas and requests

The Merative team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at Merative works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Some ideas can be implemented at Merative, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Separate IBM Curam application deployment from the database to support blue/green deployment model

Blue green deployment is an application release model that gradually transfers user traffic from a previous version of an app or microservice to a nearly identical new release—both of which are running in production.

This is done to ensure the application downtime is minimized, and support “ALWAYS ON” application behaviour.

This is particularly important for External facing applications (Curam Universal Access). This would be further helpful during Curam upgrades and quick rollbacks in-case of failures.

Curam application and DB are tightly coupled together - large part of Curam UI and business logic lives in the database as “configuration“ (IEG scripts, code table definitions, evidence definitions, schema definitions) - this prevents using blue/green deployment approach.

To support this model we’d like IBM to decouple the application from the database as much as possible.

    Just an idea of how this can be achieved without major rearchitecture of Curam:

    • Configuration artifacts, such as dynamic evidence definitions, appresources, properties, IEG script definitions, workflow definitions could be moved to a separate schema, that can be rebuilt in full from source

      • This approach would allow one application instance to point to 1 configuration schema, and a different version to point to another configuration schema.

    Hi Nimesh,

    We have reviewed your enhancement suggestion. Based on the information provided, our understanding of your request is as follows:
    • You would like to use a blue/green deployment model, but the Curam application and database are tightly coupled together so you are unable to use this approach.
    • You would like IBM to decouple certain areas of the application from the database to enable you to use blue/green deployment - this is especially important for external facing applications such as the Universal Access Responsive Web Application.

    Decoupling Universal Access specifically is aligned with our current multi-year strategy for our product, therefore we have accepted your suggestion to decouple Universal Access as a consideration for a future release. Please note that not all items under consideration will make it into a release and we may address the problem in a different way than suggested here.

    As plans are confirmed, you will be notified when a specific release includes this enhancement.

    Thank you for taking the time to share your ideas with us. We are committed to involving our users in building our product roadmap and appreciate your suggestions.

    Thank you,
