Real-World Use Cases

Streaming is a huge aspect of the data world right now and is being used by nearly every industry from manufacturing to healthcare. Would you like to learn more about the general concepts behind data pipelines and how the processes work?

This course provides a general introduction to streaming concepts including batching, queuing, and stream processing along with where they fit into data processing frameworks. It covers real-world examples of how streaming is implemented in production. It is designed as a general introduction to these concepts and does not require an extensive background in data processing.

A customer needs to reduce the time required to process a given item. You swap in a faster CPU.

A client needs to process more events simultaneously. You double the number of systems being used.

A coworker needs to reduce the processing time for a single event. You add 3 systems to the cluster.

A client would like to improve a CPU bound process. This system already has the fastest CPU available. You add an SSD.
