Event-driven workflows have improved payment processing and reduced latency across services
One area for improvement in Apache Kafka is operational complexity. Running and maintaining an Apache Kafka cluster at scale involves handling partitions, replications, retention policies, rebalancing, and monitoring, which requires strong expertise. Debugging and observability can be complex in large systems, as troubleshooting issues such as consumer lag, offset management problems, or uneven partition distribution can become challenging. The learning curve is relatively steep, requiring a good understanding of concepts such as partition, consumer group, offset commit, and delivery guarantees to avoid subtle production issues. One area where Apache Kafka could improve is the developer experience around debugging and tracing events end to end. In distributed systems, when an event passes through multiple topics and consumer services, troubleshooting can become time-consuming. Better built-in observability for tracing event flows across services would be very useful.

Easy to use, stable, has a good interface, and the security is good
I don't know if it's because of experience, but for me, it was easy to install. It's just a matter of having an RPM, then click next, next, and next again. The difficult part comes in when you have to configure the security. That is the most difficult part, but it's not that difficult. It takes less than two hours to install. Two hours max, because I did one yesterday. I installed it on AWS and it was easy to install the software. It was less than an hour for the bare minimum installation. Setting up the security, took close to two hours.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the most valuable features I have found is Kafka Connect."
"I have seen a return on investment with this solution."
"I believe that the speed, and especially the performance, are very good features."
"Apache Kafka is scalable. It is easy to add brokers."
"It's a high-performance distributed system."
"We used to lose some of our messages when we integrated them in bulk, this solution has stopped that happening."
"Kafka makes data streaming asynchronous and decouples the reliance of events on consumers."
"There are numerous possibilities that can be explored. While it may be challenging to fully comprehend the potential advantages, one key aspect is the ability to establish a proper sequence of events rather than simply dealing with a jumbled group of occurrences. These events possess their own timestamps, even if they were not initially provided with one, and are arranged in a chronological order that allows for a clear understanding of the progression of the events."
"I'm an administrator, and what I like most is the interface, the security, and the storage."
"The stability has been good."
"I am happy with the product, other than pricing I don't have any other improvements that I can suggest."
"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."
"The triggering scenarios and routing scenarios are all good, making it a very useful solution for financial institutions."
 

Cons

"If the graphical user interface was easier for the Kafka administration it would be much better. Right now, you need to use the program with the command-line interface. If the graphical user interface was easier, it could be a better product."
"GUI for Kafka infrastructure monitoring and deployment"
"One of the things I am mostly looking for is that once the message is picked up from Kafka, it should not be visible or able to be consumed by other applications, or something along those lines. That feature is not present, but it is not a limitation or anything of the sort; rather, it is a desirable feature. The next release should include a feature that prevents messages from being consumed by other applications once they are picked up by Kafka."
"We cannot apply all of our security requirements because it is hard to upload them."
"We haven't seen a return on investment with Apache Kafka. It's used for a specific use case rather than cost reduction."
"The ability to connect the producers and consumers must be improved."
"The user interface is one weakness. Sometimes, our data isn't as accessible as we'd like. It takes a lot of work to retrieve the data and the index."
"The price for the enterprise version is quite high. It would be better to have a lower price."
"In the next release, I would like to see the GUI allow you to configure the security section."
"The product's interface needs improvement."
"The pricing needs to be improved."
"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."
 

Pricing and Cost Advice

"We use the free version."
"It's quite affordable considering the value it provides."
"Apache Kafka has an open-source pricing."
"This is an open-source solution and is free to use."
"It's a premium product, so it is not price-effective for us."
"Apache Kafka is an open-source solution and there are no fees, but there are fees associated with confluence, which are based on subscription."
"Apache Kafka is an open-source solution."
"Kafka is an open-source solution, so there are no licensing costs."
"The platform is averagely priced."
"The pricing needs to be improved."
