CEO and Founder at BAssure Solutions
Plenty of adapters, beneficial for enterprises, and high availability
Pros and Cons
- "Apache Kafka has good integration capabilities and has plenty of adapters in its ecosystem if you want to build something. There are adapters for many platforms, such as Java, Azure, and Microsoft's ecosystem. Other solutions, such as Pulsar have fewer adapters available."
- "Pulsar gives more scalability to an even grouping, but Apache Kafka is used more if you want to send something in a time series-based. If this does not matter to you then Pulsar could be more customizable. Apache Kafka is nothing but a streaming system with local storage."

857,028 professionals have used our research since 2012.
What do I think about the scalability of the solution?
I would recommend Apache Kafka for any enterprise.
The amount of people using the solution depends on the application. However, the starting point is from 6,000 to 7,000 concurrent users.
How are customer service and support?
There is not any support, Apache Kafka is open-source.
Which solution did I use previously and why did I switch?
We have been experimenting with other solutions such as VMware RabbitMQ and Pulsar.
We are going to replace the Apache Kafka solution using Pulsar.
Pulsar gives more scalability to an even grouping, but Apache Kafka is used more if you want to send something in a time series-based. If this does not matter to you then Pulsar could be more customizable. Apache Kafka is nothing but a streaming system with local storage. Apache Kafka fits into many use cases, it's very direct, but if you want more specific use cases and you use Apache Kafka, Pulsar could be considered.
How was the initial setup?
Apache Kafka was simple to install. If you have a complicated clustered production, it takes time. However, for the development, it doesn't take more than one or two hours.
What about the implementation team?
We have approximately two to four technical managers that are deploying and supporting Apache Kafka. A technical manager is necessary.
What's my experience with pricing, setup cost, and licensing?
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.
What other advice do I have?
Apache Kafka is one of the best open-source solutions that are available today.
I would recommend this solution to others.

System for email and other small devices that allows for a continuous relay of transactions
Pros and Cons
- "This is a system for email and other small devices. There has been a relay of transactions continuously over the last two years it has been in production."
- "The management overhead is more compared to the messaging system. There are challenges here and there. Like for long usage, it requires restarts and nodes from time to time."
What is our primary use case?
This is a system for email and other small devices. There has been a relay of transactions continuously over the last two years it has been in production.
What is most valuable?
Besides better stability and scalability, there are no additional functionalities I'd like to see. Kafka is good at what it does.
What needs improvement?
The management overhead is more compared to the messaging system. There are challenges here and there. Like for long usage, it requires restarts and nodes from time to time.
For how long have I used the solution?
We started using this solution two years ago.
What do I think about the stability of the solution?
There are issues with stability. It's not 100% stable like ActiveMQ, but it's maybe 98% stable.
What do I think about the scalability of the solution?
With the containerized version we have used, we have faced challenges with the scalability.
How was the initial setup?
Initial setup was not easy. It requires intermediate skills.
What's my experience with pricing, setup cost, and licensing?

Program Manager at SirfinPA
Very robust and delivers messages quickly
Pros and Cons
- "Robust and delivers messages quickly."
- "The management tool could be improved."
What is our primary use case?
We deployed this solution in a project for one of our customers to synchronize the different applications; to transport information from one application to another. I'm a program manager and we are customers of Apache.
What is most valuable?
This solution is robust and delivers messages quickly. It's a simple but good product.
What needs improvement?
The management tool could be improved.
For how long have I used the solution?
I've been using this solution for the past few months.
What do I think about the scalability of the solution?
In this project, we used Kafka to synchronize 28 nodes spread out nationally and it seems scalable. We plan to consolidate the 28 nodes for national integration of nodes and schemas.
How are customer service and support?
We didn't need to contact technical support. We just allotted the software, installed it and started working with it. We carried out a lot of testing pre-development. Development was done with a company that previously used Kafka so we were able to exchange technical information.
Which solution did I use previously and why did I switch?
We previously used ActiveMQ for another project.
How was the initial setup?
The initial setup was a little complex. We carried out the development ourselves.
What's my experience with pricing, setup cost, and licensing?
Our clients purchased the license and they think it's an affordable solution.
What other advice do I have?
I recommend this solution, we're probably going to use it again in another project.
I rate this solution eight out of 10.
Which deployment model are you using for this solution?
On-premises

CTO at Estrada & Consultores
Great scalability with a high throughput and a helpful online community
Pros and Cons
- "The solution is very easy to set up."
- "While the solution scales well and easily, you need to understand your future needs and prep for the peaks."
What is our primary use case?
We primarily use the solution for upstreaming messages with different payload for our applications ranging from iOT, Food delivery and patient monitoring.
For example for one solution we have a real-time location finding, whereby a customer for the food delivery solution wants to know, where his or her order is on a map. The delivery person's mobile phone would start publishing its location to Kafka, and then Kafka processes it, and then publishes it to subscribers, or, in this case, the customer. It allows them to see information in real-time almost instantly.
How has it helped my organization?
Apache Kafka has became our main component on almost all our distributed solutions. It has helped us to delivery fast distributing messages to our customer's applications.
What is most valuable?
The solution is good for publishing transactions for commercial solutions whereby a duplicate will not affect any part of the system.
The solution is very easy to set up.
The stability is very good.
There's an online community available that can help answer questions or troubleshoot problems.
The scalability of Kafka is very good.
It provides high throughput.
What needs improvement?
Kafka can allow for duplicates, which isn't as helpful in some of our scenarios. They need to work on their duplicate management capabilities but for now developers should ensure idempotent operations for such scenarios.
While the solution scales well and easily, you need to understand your future needs and prep for the peaks.
For how long have I used the solution?
I've been using the solution for four years so far.
What do I think about the stability of the solution?
The stability is excellent. There are no bugs or glitches. It doesn't crash or freeze. It's reliable.
What do I think about the scalability of the solution?
Scaling is not really a problem with Kafka. We have used Kubernetes clusters and it is working very well. It scales up and down, almost automatically almost unnoticeable to the consumers, based upon our configuration. Kafka is just one pod inside of our cluster that scales horizontally.
We have a couple of customers that also have vertical scaling, meaning that, there's more CPU, more memory available to the Kafka pod.
How are customer service and technical support?
For Kafka, we don't actually require support from the company. We usually have people experienced in-house and sometimes we just ask in the community.
How was the initial setup?
The initial setup is easy. The majority of the tools today are really very easy to configure and setup. Docker Containers and Kubernetes, actually, have made life easier for architects as well as developers.
Nowadays, you just install the container, and then you don't have to really manage the internals at libraries, OS levels, et cetera. You just run the container. Everything is containerized.
What's my experience with pricing, setup cost, and licensing?
Apache Kafka is OpenSource, you can set it up in your own Kubernetes cluster or subscribe to Kafka providers online as a service.
What other advice do I have?
New users should understand the product capabilities. Often, people will start putting their hands in new products without knowing the capabilities and the disadvantages in specific scenarios. In our case for example, We haven't used Kafka for financial transaction processing, for which we still use IBM MQ, but It really depends upon your knowledge and experience with the product. My advice is to understand the product very well, its pros and cons and work from there.
Finally I'd rate the solution at a nine out of ten.
Which deployment model are you using for this solution?
Hybrid Cloud

Effective stream API, useful consumer groups, and highly scalable
Pros and Cons
- "The most valuable features are the stream API, consumer groups, and the way that the scaling takes place."
- "would like to see real-time event-based consumption of messages rather than the traditional way through a loop. The traditional messaging system works by listing and looping with a small wait to check to see what the messages are. A push system is where you have something that is ready to receive a message and when the message comes in and hits the partition, it goes straight to the consumer versus the consumer having to pull. I believe this consumer approach is something they are working on and may come in an upcoming release. However, that is message consumption versus message listening."
What is our primary use case?
One of our clients needed to take events out of SAP to stream them through Apache Kafka while applying data enrichment before reaching the consumers.
How has it helped my organization?
The solution can handle more speed and has horizontal scalability for both messaging, but more specifically stream processing and data enrichment. By using this solution it can reduce the number of components required in the tech stack. For example, we were taking data events out of SAP and sending them to consumers without having to go through multiple processors that were outside of the KAFKA space. Additionally, we are using Kafka from GoldenGate to propagate database updates in real-time.
What is most valuable?
The most valuable features are the stream API, consumer groups, and the way that the scaling takes place.
What needs improvement?
I would like to see real-time event-based consumption of messages rather than the traditional way through a loop. The traditional messaging system works by listing and looping with a small wait to check to see what the messages are. A push system is where you have something that is ready to receive a message and when the message comes in and hits the partition, it goes straight to the consumer versus the consumer having to pull. I believe this consumer approach is something they are working on and may come in an upcoming release. However, that is message consumption versus message listening.
Confluent created the KSQL language, but they gave it to the open-source community. I would like to see KSQL be able to be used on raw data versus structured and semi-structured data.
For how long have I used the solution?
I have been using this solution for approximately one year.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
I have found the Apache Kafka to be highly scalable
How are customer service and technical support?
The project we were working on was open-source, we were using Confluent as support and they were great.
How was the initial setup?
Apache Kafka on AWS is a bit complex. There is a third-party company called Confluent and they have the support that makes their installation much easier, especially for the on-premise deployment. You install Apache Kafka alone it can be a little complex compared to other queuing messaging solutions.
The on-premise deployment takes approximately a few days. The cloud or hybrid deployments including all the permissions, typologies, firewalls, and networking configuration can take weeks for all the accessibility issues to be resolved. However, the delay could have been client-related and not necessarily the solution.
What about the implementation team?
We provide the implementation service.
What's my experience with pricing, setup cost, and licensing?
Apache Kafka is free. My clients were using Confluent which provides high-quality support and services, and it was relatively expensive for our client. There was a lot of back and forth on negotiating the price.
Confluent has an offering that has Cloud-Based pricing. There are different packages, prices, and capabilities. The highest level being the most expensive. AWS provides services to their market, for example, to have Kafka running. I do not know what the pricing is and I am fairly confident, Azure and GCP provide similar services.
What other advice do I have?
My advice to others wanting to implement this solution is to start with data streaming projects, not simple messaging projects because while it is very good at general-purpose messaging, it is more suited and geared for when you are using it as a streaming solution.
I rate Apache Kafka an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

Difficult to configure, lacking automation, but has good community support
Pros and Cons
- "The valuable features are the group community and support."
- "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."
What is our primary use case?
We are in the early stages of testing this solution in our lab as a demo. It is in development and we are not in production at this point.
We are using this solution to relay events when they happen to multiple receivers at once to allow better functionality.
How has it helped my organization?
Apache Kafka has helped our client's online restaurant company by allowing them to take any orders and send the notifications with some other details, such as logic commands, to the different microservices.
What is most valuable?
The valuable features are the group community and support.
What needs improvement?
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.
For how long have I used the solution?
I have been using this solution for approximately three months.
What do I think about the scalability of the solution?
The solution's scalability is important for our ability to have more throughput from multiple receivers. If we need more throughput it can deliver.
Which solution did I use previously and why did I switch?
We did use other solutions previously but this solution makes things a lot easier.
How was the initial setup?
The installation is fairly easy. Additionally, there is a cloud-based version available if a use case requires it.
What about the implementation team?
We did the implementation ourselves.
What's my experience with pricing, setup cost, and licensing?
The solution is free, it is open-source.
What other advice do I have?
There is a lot of configuration involved in this solution. We have found many configurations that have helped us but it would be beneficial if there was automation.
I rate Apache Kafka a five out of ten.
