Working with JSON datasets is really common task nowadays, almost any API will output information on this format, but is still complex to manipulate this format when compared with plain-text combined with common unix commands like

ABSTRACT: Working with big volumes of data is a complicated task, but it’s even harder if you have to do everything in real time and try to figure it all out yourself. This session will use practical examples to discuss architectural best practices and lessons learned when solving real-time social media analytics, sentiment analysis, and data visualization decision-making problems with AWS.
