In this section, for the IP fraud detection case mentioned in the preceding section, we will use Apache Storm for the same log processing. Apache Storm is used for very sensitive applications in which even a 1 second delay could cause enormous losses. There are many enterprises that use Storm to detect fraud, develop recommendation engines, trigger suspicious activity, and so on. It uses Zookeeper for coordination purposes and maintains significant metadata information. Apache Storm is stateless. It is a distributed real-time processing framework that can handle one event at a time with the processing of millions of records per second per node. Streaming data can be limited or unlimited; Storm can reliably process it in both situations. The Maven app is as follows:
