Business Requirements
The customer was building a next generation Management and Reporting Solution for their storage product. The product would replace an existing thick client solution. Some of the key requirements were:
  • The product would be a Web-based and ease-of-use, advanced reporting and visualizations, intelligent insights and monitoring would be the key product differentiators
  • The application needed to be able to scale to hundreds of storage devices and retrieve, analyze and display data in real-time
  •  The key differentiator of the product would be the advanced reporting engine, which would be fronted by a easy-to-use web based front-end to create complex and smart reporting rules.
  •  An multi-channel alerting engine that could be configured to deliver alerts to users in real-time based on configured criteria
  •  Predictive analytics to help customers predict and analyze usage patterns and take intelligent decisions
  •  A mobile counterpart to the desktop web application, which would allow users to use the key functionality on the go
The Solution in Brief
DeviceDriven successfully developed and deployed a solution that comprised of the following:
Technology Stack:
  •  HTML5, AngularJS based Desktop Web application: The application front-end was developed a rich-web SPA (Single Page Application) based on the Angular JS framework. The application used secure REST API's to interact with the back-end.

  •  J2EE Web App Module: The back-end web application was based on Java 8/J2EE stack comprising Spring/JPA/Hibernate. Spring Data with its rich data repository abstractions and dynamic querying capabilities was used in the data access layer. The app provides a REST based JSON API using Spring MVC for interaction with the front-end
  •  CEP Engine: A CEP Engine is used for rolling window and other complex event processing on the incoming data 
  •  Time Series Data and Reporting: Elastic Search was chosen as the data store for the time series data based on its proven stability and ease of scale-out 
  •  Queued Data Connectors: The application interfaces with the various storage devices through persistent AMQP messages 
  •  Security and Access Control: A role-privilege based security model was developed using Spring Security and the REST API was secured using corresponding spring security annotations

  • UX - Widgets, Visualizations and Reporting: One of the key challenges was the development of a consistent and intuitive interaction interface that could scale across the myraid of features of the underlying storage device. A custom developed widgeting framework with support for drag-and-drop, positoning and state management was used, besides other extensions like Gridster and RxJS.
  • Machine Learning Algorithms for Capacity Forecasting: A Predictive/Capacity Forecasting model was developed based on machine learning algorithms that allowed customers to predict future usage patterns based on historic trends.
  • Performance and Big Data: One of the key challenges was to ensure that the application would be able to handle large volumes of data, without suffering any degradation to its real-time capabilities. This was ensured by a combination of In-Memory Computing and various architectural choices.
  • iOS/Android Mobile Apps: An iOS and Android app that provided a range of reporting capabilities was developed as an companion to the desktop app.
  • Once the product was successfully delivered, DeviceDriven supported the client through its launch and continued customer roll-out over multiple quarters. DeviceDriven also worked with the customer to further develop and maintain the product across multiple versions.
  • The project was successfully delivered and maintained by a small closely knit team of Developers, Architects and QA, who worked remotely with various customer teams and departments remotely over a multi-year time span.
