Improved data streaming and integration challenges prompt search for alternatives

The integration capabilities of Amazon MSK are not very flexible. If you have your own self-managed Kafka, that helps significantly because you can set up configurations. We are considering self-managed Kafka since our product is only one year old. The Kafka integrations are fine, but the configurations are an issue. The only issue with Amazon MSK that we are facing is the configurations. There are preset configurations and limited configurations that we can set for our unique use case. The product could improve by allowing us to set different configurations. I would also like to see Amazon MSK improve in the area of connectors. We are considering Confluent Cloud because they have many more connectors. They have KSQL DB and governance features. It is slightly costlier, but Confluent offers more flexibility with their connectors.

The solution can mimic other APIs without changing a line of code

The solution operates as a classic message broker but also as a streaming platform. It operates differently than a traditional streaming platform with storage and computing handled separately. It scales easier and better than Kafka which can be stubborn. You can even make it act like Kafka because it understands Kafka APIs. There are even companies that will sell you Kafka but underneath it is Apache Pulsar. The solution is very compatible because it can mimic other APIs without changing a line of code.

Quotes from Members

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

Pros

"Amazon MSK has significantly improved our organization by building seamless integration between systems."

"Overall, it is very cost-effective based on the workflow."

"The solution's technical support was helpful."

"Amazon MSK has contributed positively to our real-time analytics capabilities because Fortis's dashboards have dashboard health that needs to be maintained, user logs that need to be maintained, and usage tracking."

"Amazon MSK's scalability is very good."

"I have Amazon MSK integrated with other AWS services such as S3 and Lambda."

"The most valuable feature of Amazon MSK is the integration."

"MSK has a private network that's an out-of-box feature."

More Amazon MSK pros

"The solution operates as a classic message broker but also as a streaming platform."

Cons

"We need to create connectors in Amazon MSK, but there are no default connectors in AWS for that purpose."

"The only issue with Amazon MSK that we are facing is the configurations. There are preset configurations and limited configurations that we can set for our unique use case."

"Amazon MSK could improve on the features they offer. They are still lagging behind Confluence."

"Horizontal scale-out is actually not easy, making it an area where improvements are required."

"It does not autoscale. Because if you do keep it manually when you add a note to the cluster and then you register it, then it is scalable, but the fact that you have to go and do it, I think, makes it, again, a bit of some operational overhead when managing the cluster."

"It would be really helpful if Amazon MSK could provide a single installation that covers all the servers."

"The cost of using Amazon MSK is high, which is a significant disadvantage, as the increase in cloud costs by 50% to 60% does not justify the savings."

"One of the reasons why we prefer Kafka is because the support is a little bit difficult to manage with Amazon MSK."

More Amazon MSK cons

"Documentation is poor because much of it is in Chinese with no English translation."

Pricing and Cost Advice

"The platform has better pricing than one of its competitors."

"The price of Amazon MSK is less than some competitor solutions, such as Confluence."

"When you create a complete enterprise-driven architecture that is deployable on an enterprise scale, I would say that the prices of Amazon MSK and Confluent Platform become comparable."
