End-to-End Big Data Applications

The Global Big Data and Analytics Market Is to Reach $662 Billion by 2028

According to the Mordor Intelligence, the global big data and analytics market is expected to reach $375.76 billion by 2030, compared to $234.27 billion in 2025, growing at a CAGR of 9.91%. The market growth drivers are the increasing volume and variety of data, the wide adoption of cloud computing, and the rising need for data-driven decision-making.

The major applications of big data include customer analytics (accounts for the biggest market share), supply chain analytics, marketing analytics, pricing analytics, workforce analytics, and more.

In the 2024 Data and AI Leadership Executive Survey that features over 100 leading organizations from diverse industries (incl. healthcare, insurance, investment, finance, retail, manufacturing, IT, telecoms, media, and education), 87% of respondents report measurable business value from their data and analytics investments. 

End-to-End Big Data Applications: The Essence

End-to-end big data applications enable fault-tolerant, low-latency processing of massive data volumes coming from multiple sources, in various formats, and in both scheduled and unpredictable patterns.

End-to-end big data applications can be operational or analytical and can also present a combination of both types.

Operational end-to-end big data apps enable the processing of large, real-time, interactive workloads while preserving stable performance to ensure a smooth user experience. Examples of operational big data apps include social media, ridesharing platforms, e-marketplaces, large-scale IoT systems.

Analytical end-to-end big data apps use batch or real-time analysis of voluminous, multi-source data to enable predictive and prescriptive analytics, generate real-time alerts, and more.

High-Level Architecture of an End-to-End Big Data Application

Below, ScienceSoft's software engineering experts outline the most vital architecture blocks of an end-to-end big data application. Such an app can include all or several components present in the picture above.

• The data sources include internal sources like mobile and web apps gathering user-generated data, IoT devices (sensors, smart devices, wearables), and external sources (e.g., market and weather data, social media content).
• Raw data storage is a data lake that stores data for further batch processing. At this stage, any data is stored in its initial format and can be structured, unstructured, or semi-structured.
• The real-time (stream) message ingestion engine captures real-time messages (e.g., IoT readings, user app requests) and directs them for stream processing to enable immediate system response. The ingestion engine also directs real-time messages to the raw data storage to preserve it in the initial form (incl. metadata) for future analytics purposes.
• The stream processing module processes new messages or events in near real-time. In contrast, the batch module does it according to the established computation schedule (e.g., every hour, 24 hours, month), enabling cost-effective processing of voluminous historical data.

• Analytics data storage is a data warehouse storing highly structured pre-processed data as well as analytical results ready for querying in big data analytics applications. The analytics output then goes either to the reporting tools or back to the data sources (e.g., sending action triggers to IoT actuators or returning ecommerce customers’ search requests).
• The AI/ML engine is an optional module that analyzes the structured data from the analytics data storage, produces intelligent insights (e.g., detecting pre-failure equipment conditions, predicting customer behavior), and feeds these insights into the corresponding processing modules. An accompanying ML training module is needed to update the engine, continuously improving its accuracy.
• Data orchestration and governance system automates repeating data processing operations (e.g., transforming source data and moving it between the architecture modules) and ensures complete data quality, protection, and compliance throughout the analytics lifecycle.
