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

"Kafka's most valuable feature is its user-friendliness."
"As a software developer, I have found Apache Kafka's support to be the most valuable...The solution is easy to integrate with any of our systems."
"The stream processing is a very valuable aspect of the solution for us."
"Kafka is an open-source tool that's easy to use in our country, and the command line interface is powerful."
"For example, when you want to send a message to inform all your clients about a new feature, you can publish that message to a single topic in Apache Kafka. This allows all clients subscribed to that topic to receive the message. On the other hand, if you need to send billing information to a specific customer, you can publish that message on a topic dedicated to that customer. This message can then be sent as an SMS to the customer, allowing them to view it on their mobile device."
"Apache Kafka is an open-source solution that can be used for messaging or event processing."
"This is the best tool I have ever used for asynchronous, event-based solutions."
"Apache Kafka is effective when dealing with large volumes of data flowing at high speeds, requiring real-time processing."
"The stability has been good."
"I'm an administrator, and what I like most is the interface, the security, and the storage."
"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 am happy with the product, other than pricing I don't have any other improvements that I can suggest."
 

Cons

"The support on Apache Kafka could be improved."
"We struggled a bit with the built-in data transformations because it was a challenge to get them up and running the way we wanted."
"More Windows support, I believe, is one area where it can improve. We need to wrap it as a service, but there isn't one built into Windows."
"We haven't seen a return on investment with Apache Kafka. It's used for a specific use case rather than cost reduction."
"The only reason I give Kafka as product a low rating is because there are far superior and cheaper alternatives in cloud-based solutions, where we save money on manpower, electricity, servers, datacenters, networking, etc."
"The support from Apache Kafka could improve. Their engineers at times do not know what the solutions can do."
"One area for improvement in Apache Kafka is operational complexity."
"The solution could always add a few more features to enhance its usage."
"The pricing needs to be improved."
"The product's interface needs improvement."
"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."
"In the next release, I would like to see the GUI allow you to configure the security section."
 

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."
"The price of the solution is low."
"Apache Kafka is free."
"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."
"This is an open-source version."
"It's a premium product, so it is not price-effective for us."
"It's quite affordable considering the value it provides."
"It is open source software."
"The platform is averagely priced."
"The pricing needs to be improved."
