All about data streams and how you can do it too!

This talk was presented at the October '18 edition of the JS Monthly meetup in London, UK.

Abstract:
Streaming data is evidently taking over the way user applications consume data. The realtime nature of streaming data allows developers to create data-centric applications that are critically dependant on the speed at which this data arrives from the source to the processing site. Data speed thus serves to be the primary driving force of the business. However, if you are spending enormous resources on creating amazingly useful data, figuring out how to actually stream and distribute your data and building an architecture that realizes the worth of your data and the realtime requirement of it, is often a huge challenge, technologically.

In this talk, we'll understand what data streams are and learn under-the-hood technical concepts that are part of this fairly new way of sharing data across applications and businesses. Further, we’ll see how you can solve the streaming data distribution problem, that ensures interoperability and scalability with least effort.
