Apache Kafka : It’s a distributed and dependable messaging system that can manage large amounts of data and transfer messages from one end-point to the next. Kafka is meant to allow a single cluster to act as a big organization’s primary data backbone. It may be expanded elastically and transparently without any downtime. To allow data streams bigger than the capabilities of any one computer and clusters of coordinated users, data streams are partitioned and disseminated across a cluster of machines.
Apache Storm : It’s a real-time message processing system that allows you to modify and alter data in real time. Storm takes the data from Kafka and does the necessary processing. It makes it simple to handle unlimited streams of data safely, conducting real-time processing in the same way as Hadoop performed batch processing. Storm is easy to use, works with any computer language, and is a lot of fun.
