Review summaries and opinions

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

ROI

Sentiment score
7.0
Apache Kafka offers substantial returns, especially in high-value applications, with enhanced data buffering, cost savings, and ease of use.
Sentiment score
7.1
IBM MQ offers cost-effective, reliable integration, enhancing efficiency, minimizing data loss, and achieving ROI within two years.
It's a product which integrates the external systems with internal systems or among the systems themselves, making it an essential technology component required to integrate multiple systems.
 

Customer Service

Sentiment score
5.8
Apache Kafka's support is community-driven, with varying user experiences and enhanced options available through paid subscriptions and consultants.
Sentiment score
6.9
IBM MQ support is efficient yet inconsistent, with quick issue resolution but delays and documentation improvements needed for complex issues.
The Apache community provides support for the open-source version.
There is plenty of community support available online.
We cannot hold on to the project for a long time just to wait for IBM to fix the issues.
The response time for IBM MQ support could be better because when we are using IBM MQ and something goes wrong, support is required as the resource availability of the IBM product is very limited.
With containerized flavors of these products, we are having a tough time dealing with PMRs because the versions are new to IBM.
 

Scalability Issues

Sentiment score
7.8
Apache Kafka is praised for its robust scalability, efficiently handling high data throughput, with some challenges in cluster management.
Sentiment score
7.5
IBM MQ scales well across environments but may face challenges with configuration and hardware in certain scenarios.
Customers have not faced issues with user growth or data streaming needs.
IBM MQ handles many thousands of messages in a second, indicating good scalability.
In our environment, we do not have horizontal scaling for IBM MQ, but as demand increases, we would just vertically scale it.
Performance-wise, it is scalable, and other features such as DR, DC, replication, and active passive mode are complex to configure, but it remains scalable.
 

Stability Issues

Sentiment score
7.7
Apache Kafka is stable and performs well with high data volumes, though some configurations may affect its reliability.
Sentiment score
8.1
IBM MQ is praised for stability, minimal downtime, and reliability, with strong performance and regular updates enhancing user satisfaction.
Apache Kafka is stable.
This feature of Apache Kafka has helped enhance our system stability when handling high volume data.
We have never had any downtime or crashes since it's been running.
The transaction is always guaranteed with IBM MQ, which is the main reason I have been working with it for fifteen years while dealing with financial transactions or messages.
 

Room For Improvement

Enhancing Kafka involves user-friendly UI, improved monitoring, reduced ZooKeeper dependency, better documentation, flexibility, and integration with other platforms.
IBM MQ users seek enhanced security, user interfaces, monitoring, cloud integration, graphical admin, mobile/web support, and cost-effective training.
The performance angle is critical, and while it works in milliseconds, the goal is to move towards microseconds.
We are always trying to find the best configs, which is a challenge.
A more user-friendly interface and better management consoles with improved documentation could be beneficial.
Having a graphical user interface would improve usability.
The pricing model for IBM MQ could be more flexible for clients.
They don't meet our standards due to the timing to get a person with knowledge.
 

Setup Cost

Apache Kafka is free to use, but costs vary for managed services and enterprise solutions, potentially exceeding 100,000 euros annually.
IBM MQ's high cost is justified by performance and scalability, yet some prefer open-source alternatives for affordability.
The open-source version of Apache Kafka results in minimal costs, mainly linked to accessing documentation and limited support.
Its pricing is reasonable.
It's possible to get some training, but the cost of this learning is expensive.
The price of IBM MQ is definitely on the higher side.
I am not exactly sure about the licensing cost compared to similar products, but I assume it is affordable since we continue to use it, and it is also used by our customers.
 

Valuable Features

Apache Kafka excels in scalability, real-time streaming, and flexibility, ideal for large data volumes and event-driven architectures.
IBM MQ is valued for reliable data transfer, seamless integration, scalability, security, and ease of administration across industries.
Apache Kafka is effective when dealing with large volumes of data flowing at high speeds, requiring real-time processing.
It allows the use of data in motion, allowing data to propagate from one source to another while it is in motion.
The impact of Apache Kafka's scalability features on my organization and data processing capabilities depends on how many messages each company wants to receive.
These are financial transactions, so we do not want to lose the message at any cost.
There is a saying that for the last 30 years IBM MQ has never been hacked.
It's time-tested, very stable, highly resilient, and has all the features to troubleshoot even if something goes wrong.

Data streaming transforms real-time data movement with impressive scalability
I worked with Apache Kafka for customers in the financial industry and OTT platforms. They use Kafka particularly for data streaming. Companies offering movie and entertainment as a service, similar to Netflix, use Kafka Apache Kafka offers unique data streaming. It allows the use of data in…
Md Al-Amin - PeerSpot reviewer
Reliable and secure performance consistently enhances message transfer
IBM MQ is more reliable and secure than other software. There is a saying that for the last 30 years IBM MQ has never been hacked. It is more secure and reliable. Whenever the configuration is done, I do not have to touch it again. It works fine, it is stable, and its communication is to the point and accurate. All performance-related aspects are better. Performance-wise, it is scalable, and other features such as DR, DC, replication, and active passive mode are complex to configure, but it remains scalable. The pricing model for IBM MQ could be more flexible for clients.

Apache Kafka is open source and can be used for free. It has very good log management and has a way to store the data used for analytics. Apache Kafka is very good if you have a high number of users. This tool has great scalability with high throughput and a very helpful supportive online community. However, Kafka does not provide control over the message queue, so it is difficult to know whether messages are being delivered, lost, or duplicated. We would like to see more adapters for connecting to different systems made available. I think this would be a better product if the graphical user interface was easier. The manual calculations needed for this solution can be difficult. If the process was automated, it would be a much better product. IBM MQ has a very strong reputation and is very robust with great stability. This solution is easy to use, simple to configure, and integrates well with our enterprise ecosystem and protocols. IBM ensures message delivery. You can track and trace everything. If a message doesn’t arrive at its destination, it will go back to the queue; this ensures no message is ever lost. This is a huge selling point for us. IBM MQ does not handle huge volume very well, though. There are some limitations to the queues. If these limitations could be relaxed, it would be a better product for us. You have to license per application and installation, so scaling up can get very costly very quickly. Conclusion Apache Kafka is a cost-effective solution for high-volume, multi-source data collection. If you are in a high-growth trajectory and if total message accountability and tracking is not a huge issue for you, this solution may work well for you. IBM MQ is a licensed product and can be very expensive, it also does not scale easily, which can be very problematic. IBM MQ requires a definite skillset that not many people have, which can be an issue for some and it affects the fast responsive support of this solution.
