Room For Improvement

PubSub+ Platform needs simpler usage, better connectivity, enhanced tools, robust authentication, and improved integration with open-source and existing applications.
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
It was as impressive as Kafka, better than Kafka based on my experience working on the Solace and Kafka white paper.
freelancer at a financial services firm with 1,001-5,000 employees
There is a lack of functionality in PubSub+ Platform; Solace has introduced microservices and micro-integrations recently with some capabilities, but they can improve on these.
Integration Architect at a tech services company with 11-50 employees
Some advanced configurations in PubSub+ Platform could be made simpler so users can better understand them, and better visualization for event streaming is needed.

Setup Cost

Enterprise buyers value EMQX for its cost-effectiveness, leveraging open-source advantages and minimizing expenses through cloud providers like AWS.
Enterprise users value PubSub+ Platform’s flexibility, free version, and tailored agreements despite perceived high licensing 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
The pricing and setup cost of PubSub+ Platform is very seamless and reliable for medium and large-scale enterprises.
Angular Developer at Flourish Software
Pricing-wise for PubSub+ Platform, I find it a little expensive, so I would rate it at six.

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.

Messaging design has become visual and reliable and now supports fast microservice communication
The unique functions I appreciate about PubSub+ Platform are that it allows me to design my solution in a graphical manner, which is not available in many other products, and the design can also be pushed to the actual infrastructure layer, making it quite advantageous. Mesh technology is useful in scenarios where different geographies have to be connected, although such situations are not commonly found. It is beneficial but not a super-used feature of PubSub+ Platform. The event replay function is quite mature in PubSub+ Platform, allowing me to replay messages that are days in the past, which is a good feature. The main benefits PubSub+ Platform provides for the end-user include building a robust and scalable system with very low network latency, which improves the customer experience, whether using mobile phones or applications. This type of messaging framework is extremely important, and Solace is a very good product in that space. Nowadays, most applications are built using microservices technology, with small microservices interchanging messages via PubSub+ Platform. Without it, realizing a scalable system would not be possible; for example, one cannot have Netflix or similar services that require quick data transit and a good user experience, ensuring that data cannot be lost in transit. The analytics part of PubSub+ Platform is quite useful as it can connect with many analytical software tools, mainly for analysis of system logs, such as Splunk, DataDog, or Prometheus. It has the flexibility to connect with any of these and supports OpenTelemetry, which is not available in many other products, making traceability very easy. I can see how a message travels from a source system to the target system, end-to-end, along with what happens to that message along the path, making the analytics quite good.
