The world that we live in is driven by data. Gaining powerful real-time insights into real-world data lets your business have an edge. Data streaming allows the continuous capturing and processing of data originating from various data sources, and that’s why good streaming data platforms matter.

Data streaming platforms are scalable, distributed, and highly efficient systems that ensure the reliable processing of data streams. They support data aggregation and analysis and often come with a unified dashboard to visualize your data.


You can choose from a wide range of data streaming platforms and solutions — from fully managed systems like Confluent Cloud and Amazon Kinesis to open-source solutions like Arroyo and Fluvio.

What are some use cases for data streaming?

Data streaming platforms have a wide range of use cases that they cover. Let’s quickly go through a few of them:

  • Fraud detection is handled by continuously analyzing transactions, user behavior, and patterns.
  • Stock market trading data is captured by multiple systems that do blazing-fast high-volume trades based on market analysis.
  • Custom insights through real-time market data provide e-commerce marketplaces with the right audience to target their products.
  • There are millions of sensors in various systems providing real-world data and helping in predictive information like weather forecasts.

Here are the best data platforms for all your real-time analysis and stream processing needs.
