A strong and reliable tool for real-time data streaming **Rating:** 4.5/5.0 stars **Reviewed by:** Akshat J. | Infrastructure / DevOps Engineer - 2, Mid-Market (51-1000 emp.) **Reviewed Date:** July 28, 2025 **What do you like best about Apache Kafka?** Kafka handles large volumes of data really well and is very reliable once set up properly. We use it for real-time data processing between different parts of our system. It's fast, fault-tolerant, and can scale easily when traffic grows. The publish-subscribe model makes it simple to connect producers and consumers across different services. **What do you dislike about Apache Kafka?** Initial setup and configuration can be a bit tricky, especially if you’re new to distributed systems. Managing brokers and zookeepers manually can get complex. Also, monitoring and debugging issues sometimes takes extra effort unless you have good tooling in place. **What problems is Apache Kafka solving and how is that benefiting you?** Kafka helps us move data between microservices in near real-time without delays. It’s useful for logging, metrics pipelines, user activity tracking, and even for alerting workflows. It keeps our system decoupled and helps scale better as we grow. ### 3.
