I have not used customer support for EMQX because I can understand it on my own by watching tutorials on YouTube, even if they are not from the official EMQX customer service, so I am satisfied with self-learning.
Research Engineer at a consultancy with 11-50 employees
We cannot hold on to the project for a long time just to wait for IBM to fix the issues.
Dev lead at a financial services firm with 1,001-5,000 employees
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.
Senior System Analyst at Thakral
With containerized flavors of these products, we are having a tough time dealing with PMRs because the versions are new to IBM.

Room For Improvement

EMQX users seek improved cost, reliability, and features like SSL/TLS management, monitoring, and AI integration for enhanced support.
IBM MQ users seek enhanced security, cloud integration, intuitive interfaces, performance improvements, lower pricing, and active-active clustering.
A centralized dashboard where we can add multiple clusters in a single place would be easier to monitor.
Senior Software Engineer at a tech vendor with 51-200 employees
I think EMQX needs to improve its logs. When I encounter a problem with EMQX error messages, it is very difficult to trace the logs and find the real reason for the error to fix it.
Java Technical Lead at a financial services firm with 501-1,000 employees
If there were an option to utilize serverless without that TLS and SSL overhead, the embedded system would not experience the overhead burden.
Saa S Company
Having a graphical user interface would improve usability.
Senior Software Test Analyst at CoCre8 Technology Solutions
The pricing model for IBM MQ could be more flexible for clients.
Senior System Analyst at Thakral
They don't meet our standards due to the timing to get a person with knowledge.
Information Technology Solution Consultant
 

Setup Cost

Enterprise buyers value EMQX for its cost-effectiveness, leveraging open-source advantages and minimizing expenses through cloud providers like AWS.
IBM MQ's pricing is high compared to open-source alternatives, though enterprise agreements and flexible licensing can reduce costs.
We do not need to pay for what we are not using.
Senior Software Engineer at a tech vendor with 51-200 employees
AWS costing for the product that is maintained is quite high.
Senior Software Engineer
EMQX is open-source and MQTT is also an open-source protocol, so the cost is less.
Industrial Digitalization Engineer
It's not cheap.
Enterprise Technical Leader at a tech vendor with 10,001+ employees
It's possible to get some training, but the cost of this learning is expensive.
SWIFT manager at Raiffeisen Bank Aval
The price of IBM MQ is definitely on the higher side.
Dev lead at a financial services firm with 1,001-5,000 employees

Connected millions of iot devices and manage real time pub sub control and flexible access rules
When going with the open-source EMQX version, there are limitations provided. For example, the webhooks use case cannot be scaled to as large a scale compared to the enterprise edition of EMQX. The open-source version helps a great deal with work in the company. The way this resource helps nurture the IoT device paradigm is greatly helpful for developers working newly on this system because the onboarding part of EMQX is very easy and developer-friendly. Someone who wants to dive into it can easily implement and make the system robust based on the technologies it provides. EMQX provides API connections for applications. HTTP calls can be made to EMQX to get updates from the client. Those connections should be made asynchronously. The webhook part handles this well, but when it comes to the API part, when the load and payload of the MQTT topics and messages are very heavy, sometimes unknown errors occur, and logs and errors must be found. When a specific log session is created for that client, the readability of those logs is not good. The platform itself does not need improvement, but when it comes to developer-friendly implementations of EMQX, there are some pain points that need attention. The visibility of logs, error logs, and information logs inside the built-in monitoring needs work because developers, when they implement code or any kind of specific tools, need proper control over the system. Without that control, there is no point in implementing anything at all. The monitoring part needs work. When it comes to the flow chart of how different clients are connected with different devices, there is a feature inside EMQX called Flow. When that Flow is in place, clients (devices) should be controllable from that Flow itself. These are the most important improvements that need to be addressed.

Has faced unexpected VM restarts but continues to deliver messages reliably
I'm not sure if we've utilized IBM MQ's high availability. Our MQ VMs are set up in clusters, and I think our queue managers are set up in pairs. However, I don't know if we actually use any specific high availability features of IBM MQ that are out of the box. We have it architected with high availability because we use F5 load balancers, and everything about our architecture is highly available. I haven't personally used the management tools with IBM MQ, but we do have them, and our middleware folks leverage them. I can't really comment on them because I don't use them myself. I don't think the management tools help optimize message flows, and I'm not really aware of how they help in this. I'm not familiar with dynamic routing for IBM MQ.
