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 most valuable feature is the support for a high volume of data."
"Kafka is scalable. It can manage a high volume of data from many sources."
"The most valuable feature is the documentation, which is good and clear."
"We get amazing throughput. We don't get any delay."
"Resiliency is great and also the fact that it handles different data formats."
"Apache Kafka is scalable. It is easy to add brokers."
"Its availability is brilliant."
"Apache Kafka has helped out the organization because we leverage it for all our eCommerce real-time analytics use cases."
"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 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."
 

Cons

"The solution should be easier to manage. It needs to improve its visualization feature in the next release."
"The graphical user environment is currently lacking in Apache."
"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."
"There have been some challenges with monitoring Apache Kafka, as there are currently only a few production-grade solutions available, which are all under enterprise license and therefore not easily accessible. The speaker has not had access to any of these solutions and has instead relied on tools, such as Dynatrace, which do not provide sufficient insight into the Apache Kafka system. While there are other tools available, they do not offer the same level of real-time data as enterprise solutions."
"Prioritization of messages in Apache Kafka could improve."
"Kafka requires non-trivial expertise with DevOps to deploy in production at scale."
"Something that could be improved is having an interface to monitor the consuming rate."
"It’s a trial-and-error process with no one-size-fits-all solution. Issues may arise until it’s appropriately tuned."
"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."
"In the next release, I would like to see the GUI allow you to configure the security section."
 

Pricing and Cost Advice

"The solution is open source; it's free to use."
"The price of Apache Kafka is good."
"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."
"Apache Kafka has an open-source pricing."
"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."
"Kafka is open-source and it is cheaper than any other product."
"Apache Kafka is an open-sourced solution. There are fees if you want the support, and I would recommend it for enterprises. There are annual subscriptions available."
"When starting to look at a distributed message system, look for a cloud solution first. It is an easier entry point than an on-premises hardware solution."
"The pricing needs to be improved."
"The platform is averagely priced."
