Introduction To KAFKA: OTKafkaDiaries

Starting Our Journey:

This year’s pandemic has forced businesses all around the world to adopt a “remote-first” approach for executing daily operations. Although our lives have been greatly disrupted due to lockdown measures and economic impact, we have managed a balance in our social lives through online modes such as shopping, learning, messaging, gaming, and other activities.

Modern software design is also taking a remote-first mindset to ensure that users can collaborate and share information within each app, including the ability to interact with real-time data processing.
