Platform Based Business Model

Modern, digitally empowered businesses have been successful in rapid disruption and value creation, through platforms. Global enterprises, ensure competitive advantage, enduring customer relations and revenue growth, need to embark on digital business transformation initiatives. They need to create new digital businesses or transform existing ones to platform-based business models. McKinsey in its February article titled `The Platform Play: How to Operate like a Tech Company', explains this concept articulately, "Becoming a platform-based company is ultimately a question of mind-set. It requires both the determination to stay the course and the flexibility to change and adjust based on what platform teams learn. By committing to this approach, IT can stop slowing down change and start accelerating it".

Highlights of platform-based business models:

  • Creates/enhances and facilitates the ecosystem, facilitates value exchange between different stakeholders in the ecosystem.
  • Ensures that enterprises can coexist with disruptive and legacy business models while embracing new digital initiatives.
  • Extracts untapped value from existing organizational assets/systems and combines with new capabilities to stimulate meaningful engagement with stakeholders.

Creating platforms in traditional enterprises requires the ability to architect, design, develop, maintain and enhance platforms as per the digital agenda. These platforms should be based on modern technology stack, be cloud-based and have the ability to integrate with existing systems. Sonata helps create these platforms to accelerate digital transformation by building, extending and enhancing developing and managing platforms that adhere to OPEN, SCALABLE, CONNECTED and INTELLIGENT platform characteristics.

This document provides details of Sonata's Platformation offering - Custom Platform Engineering, and where it has been successfully used to help customers adapt Platformation.

How Sonata Can help achieve PBBM

Sonata has a well-defined seven step methodology to help enterprises to adopt a platform-based business model:

  • Platform Maturity Assessment: Sonata conducts digital, business and technology assessment , benchmarks industry best practices, and reports recommendations
  • Customer Digital Agenda: Sonata creates the digital agenda for the enterprise and provides its recommendation for business transformation.
  • Platform Ecosystem & Design Thinking : Sonata, adapting the `Design Thinking' process, co-creates the platform ecosystem & business model by mapping and identifying participant journeys, pains, gains and opportunities.
  • Digital Business Processes: Digital Business Process library for the enterprise is created along with `As Is – To Be' gap analysis. Based on these recommendations, future business processes and MARCHITECTURE SONATA SOFTWARE services are generated.
  • Platform Characteristics: Open, Connected, Scalable and Intelligent characteristics emerge based on which, the `To Be' platform based on Sonata's 16 point technology framework is derived.
  • Platformation Roadmap Proposal: Recommendation of roadmap, quick wins, phased data, cloud, platform engineering is articulated. Also, the scope, implementation, execution plan along with budget and timelines is proposed.
  • Implementation to Execution Approach: Execution methodology is defined. Comprehensive Plans for pilots, programs and projects are created and technology decisions for build/buy are arrived at. Platformation KPIs are continually measured and governed.

Platform Characteristics

Open, Connected, Intelligent, Scalable are the four fundamental characteristics of platforms. Thus, if an enterprise's technology ecosystem exhibits these characteristics, it can be classified as a platform.


4 Key Elements

  • Service Oriented approach (Microservices, Micro front-ends, databases for use cases etc.)
  • Layered separation of concern approach (Consumer Layer, Application Layer, Data Layer, Infra Layer, Integration Layer)
  • Design-thinking led approach
  • Hyper Productivity (Tools and Frameworks)
  • Full Automation (Agile and DevOps)

Architectural Patterns

  • API-first approach with micro-services architecture for higher flexibility in integrating various systems and composing required platform services
  • Cloud-first approach to development and operations minimizing the overheads in managing environments and technology stacks
  • Distributed transactions to support events that impact multiple data sources and systems
  • Real-time analytics leveraging Big Data and IoT / Telemetry coupled with location sensing technologies that help in providing contextual and personalized user experience, thereby enabling better and faster decision making on the platform
  • Self-provisioning cloud infrastructure coupled with micro-services architecture for dynamically scaling specific services based on demand
  • Robotic process automation techniques coupled with self-learning systems for reducing manual tasks in executing business processes as well as system operations

Key Constructs

Sonata's Platform Engineering & Architecture Blueprint (PEAB Framework) provides for a robust platform architecture for creating an ecosystem-based model consisting of API, UX, Data, Device/IOT connectivity, Microservices, cloud components and engineering practices for speed and reliability.


Sonata's PEAB framework based on:

  • API framework/reference architecture,
  • Cloud adoption framework,
  • Mobile enablement platform (Halosys),
  • IOT reference model

enables building the connected capability of this platform.


Digital experience must be delivered seamlessly across different devices, channels and should have the ability to connect to different APIs/Services and deliver seamless and native user experience. The intelligent experience to the digital users and adaptability of the application based on the device are some of the key aspects of the UX platform


Platforms need to be scalable to support new business lines, products, locations, markets and an elastic user base. Sonata's PEAB framework is anchored on Microservices-based architecture and cloud-based platform services. This architecture enables easier adoption of cloud service and architecture innovations that empower scalability.


Data is the heart of the platform and hence our data strategy and reference architecture consists of process and tools to Identify, Store, Integrate, Share and Govern Data. This coupled with Robotic Process Automation Framework, Conversational User Interface/Front End Development framework and an engineering process based on contemporary UX design principles, leverage Design Thinking for INTELLIGENT user experience with insights, predictions and recommendations to the user/enterprise. With Machine learning/AI, this intelligence can evolve and mature with time.


Platform-based Business Model, by its very nature, demands scalable infrastructure based on the demand of the services, duration and the business model requirements. By this definition, Cloud is the infrastructure backbone for platform-based businesses to meet the scalability and connected requirements of the platform.
