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

"The message bus capabilities, basically sending messages to it, and the way it handles events or messages is pretty good."
"I like Kafka's flexibility, stability, reliability, and robustness."
"Kafka is scalable to any degree we want, and it has several connectors available for integration in multiple languages, making it easier for integration."
"Its availability is brilliant."
"A great streaming platform."
"The solution is very scalable. We started with a cluster of three and then scaled it to seven."
"Kafka is scalable. It can manage a high volume of data from many sources."
"I like Kafka's flexibility, stability, reliability, and robustness."
"The triggering scenarios and routing scenarios are all good, making it a very useful solution for financial institutions."
"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."
"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."
 

Cons

"The repository isn't working very well. It's not user friendly."
"The manageability should be improved. There are lots of things we need to manage and it should have a function that enables us to manage them all cohesively."
"In the next release, I would like for there to be some authorization and HTL security."
"The GUI tools for monitoring and support are still very basic and not very rich. There is no help in determining a shard key for performance."
"Some vendors don't offer extra features for monitoring."
"The management overhead is more compared to the messaging system. There are challenges here and there, like for long usage, it requires restarts and nodes from time to time."
"The solution can improve by having automation for developers. We have done many manual calculations and it has been difficult but if it was automated it would be much better."
"The graphical user environment is currently lacking."
"The product's interface needs improvement."
"The pricing needs to be improved."
"In the next release, I would like to see the GUI allow you to configure the security section."
"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."
"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

"I rate Apache Kafka's pricing a five on a scale of one to ten, where one is cheap and ten is expensive. There are no additional costs apart from the licensing fees for Apache Kafka."
"Apache Kafka is open-source and can be used free of charge."
"I was using the product's free version."
"The price of Apache Kafka is good."
"The price for the enterprise version is quite high. For on-premise, there is an annual fee, which starts at 60,000 euros, but it is usually higher than 100,000 euros. The cost for a project including the subscription is usually between 100,000 to 200,000 euros. The cost also depends on the level of support. There are two different levels of support."
"The solution is open source."
"The price of the solution is low."
"The cost can vary depending on the provider and the specific flavor or version you use. I'm not very knowledgeable about the pricing details."
"The pricing needs to be improved."
"The platform is averagely priced."
