    Challenge Details

    What is Predix?

    The Predix platform is a cloud-based Platform-as-a-Service (PaaS) for the Industrial Internet. The Predix platform provides tools, framework, guidelines, and best practices that enable you to create solutions to run industrial-scale analytics. As it connects machines, data, people, and other assets, the Predix platform uses leading technologies for distributed computing, big-data analytics, asset data management, and machine-to-machine communication. A comprehensive platform overview can be found here. If you have previously used or are familiar with other platforms-as-a-service (AWS, Google Cloud Platform, Heroku, IBM Bluemix), this should feel right at home.

    Requirements for this challenge

    As your introduction to the Predix platform services, you will be incorporating “User Account and Authentication” (UAA) services in the application. UAA services will be mostly required to access other applications, hence it would be a good idea to get acquainted with them.


    This challenge requires you to create a login page, to allow a user to login to your app, using OAuth using UAA service.


    Important Note:

    While setting up your app name for this challenge, please include your topcoder username in the app name, to enable us to distinguish between apps. For example, if your username is xyz, then your app name could be xyz-weather.

    Step 1: Read and complete the steps in the detailed guide to incorporate UAA service.  UWF.PNG


    Click “Create Service”

    Click on your UAA Service

    Click “Open Service Instance” on the left

    Log in to your UAA Dashboard by entering the password

    Create 1 or 2 users.

    cf bind-service <your-app-name> <your-uaa service>

    Step 2: Create a login page, which uses the configured UAA service.

    The tutorial here, outlines a step by step approach.

    Final Submission Guidelines

    1. Provide your application URL (that includes your Topcoder username) in a text file and upload in the challenge.
    2. Provide one sample user name and password in the file for us to login and check the login process.
    3. You are free to use NodeJS, Java or any other supported technology.

    Reliability Rating and Bonus

    For challenges that have a reliability bonus, the bonus depends on the reliability rating at the moment of registration for that project. A participant with no previous projects is considered to have no reliability rating, and therefore gets no bonus. Reliability bonus does not apply to Digital Run winnings. Since reliability rating is based on the past 15 projects, it can only have 15 discrete values.
