Streamlines our processes, and we don't need to configure any VPCs; it's automatic

We don't have many use cases involving ingesting large amounts of data and scaling up and down. We have a clear understanding of our data volume, which remains relatively constant throughout the week. While we're aware of other features Amazon MSK offers, we feel confident in our current setup. If our requirements change significantly in the future, we'll reassess our needs and consider adopting Amazon MSK.

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

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

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

"It provides installations, scaling, and other functionalities straight out of the box."

"Amazon MSK has good integration because our team has been undergoing significant changes. Coupling it with MSK within AWS is helpful. We don't have to set up additionals or monitor external environments. This"

"It offers good stability."

"Amazon MSK's scalability is very good."

"The scalability and usability are quite remarkable."

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

More Amazon MSK pros

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

Cons

"The product's schema support needs enhancement. It will help enhance integration with many kinds of languages of programming languages, especially for environments using languages like .NET."

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

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

"The configuration seems a little complex and the documentation on the product is not available."

"It should be more flexible, integration-wise."

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

"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."

"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."

More Amazon MSK cons

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

Pricing and Cost Advice

"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."

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