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

"Supports more than 10,000 events/second, scalability, and replication, and it is a good product for event-driven architecture."
"The most valuable feature of Apache Kafka is the clustering which is very easy to scale and we have multiple servers all over our platforms. It has been useful for stability and performance."
"We implemented the notification system between our components, and we found that Apache Kafka performs well in scalability, improving our organization because of the scalability and the comfort of a fail-safe or disaster recovery it provides."
"The open-source version is relatively straightforward to set up and only takes a few minutes."
"It's very easy to keep to install and it's pretty stable."
"The solution is stable, and the most fantastic thing about it is its throughput."
"It has become dead simple to connect different application and services, saving a lot of development hours."
"The most valuable feature of Apache Kafka is Kafka Connect."
"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."
"The stability has been good."
 

Cons

"Apache Kafka could improve data loss and compatibility with Spark."
"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."
"For personal preferences, since we use Managed Kafka in AWS, I would appreciate having some kind of UI integrated into Apache Kafka for connecting to it because using code to connect it is basic, but we can use a UI."
"It's not possible to substitute IBM MQ with Apache Kafka because the JMS part is not very stable."
"For the original Kafka, there is room for improvement in terms of latency spikes and resource consumption. It consumes a lot of memory."
"Kafka does not provide control over the message queue, so we do not know whether we are experiencing lost or duplicate messages."
"The interface of Apache Kafka could be significantly better."
"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."
"In the next release, I would like to see the GUI allow you to configure the security section."
"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."
 

Pricing and Cost Advice

"The price of Apache Kafka is good."
"We are using the free version of Apache Kafka."
"This is an open-source version."
"I would not subscribe to the Confluent platform, but rather stay on the free open source version. The extra cost wasn't justified."
"The solution is open source."
"Licensing issues are not applicable. Apache licensing makes it simple with almost zero cost for the software itself."
"It's quite affordable considering the value it provides."
"Apache Kafka is an open-source solution."
"The platform is averagely priced."
"The pricing needs to be improved."
