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.

From my perspective, the biggest challenge with VMware right now is the pricing. To be very honest, in many cases I find myself recommending alternative solutions instead of VMware. Even if those alternatives come with a bit more complexity, customers are often more willing to accept that than the current VMware pricing model. In the past, VMware used a socket-based licensing model, which was easier for customers to understand and budget for. Now the shift to a core-based licensing model has significantly increased costs for many environments, especially for organizations running modern high-core CPUs. One positive aspect of the new model is that VMware has bundled several components together. For example, earlier when deploying vSphere, customers also had to purchase vCenter separately for management. Now multiple components are packaged into a single SKU, which simplifies some aspects of procurement and deployment. While this consolidation has its benefits, the overall licensing and commercial costs remain very high. Pricing is not the only issue. I believe Broadcom also needs to reconsider its strategy in light of the current market conditions. The approach they are taking may be strategic from a business perspective, but from what I see in the field, it is leading to lost opportunities. Many customers who previously relied on VMware are now actively exploring alternative virtualization platforms. I’m not sure where this direction will ultimately lead, but based on my experience, it is already affecting adoption. Since you’ve been trying to reach me for some time—and we also had a discussion a couple of years ago—I hope this feedback helps Broadcom understand the current sentiment in the market and potentially make adjustments. Another important concern is the way features are bundled. In many cases, customers only need basic virtualization and high availability capabilities. However, the current packaging often includes additional features that they may not need. A good analogy is that if a customer only needs an entry-level car, we shouldn’t be forced to sell them a Rolls-Royce. VMware could benefit from adopting a more modular or à la carte licensing model, where customers can choose only the components they truly require. For example, if a customer only needs core virtualization functionality, they should be able to purchase just that. This would allow partners and solution providers to better align solutions with customer requirements and position VMware more competitively in the market. Another challenge I want to highlight is the pricing model based on U.S. dollars and the way multi-year licensing is handled. In many enterprise and government projects, customers prefer to commit to three-year or five-year licenses and pay the full amount upfront. However, in approximately 20% of the deals I work on, we lose opportunities because VMware only provides dollar-based pricing for the first year. When it comes to the following years, the contract requires renewals annually rather than allowing a fixed multi-year upfront payment. This approach is particularly problematic for government and public sector customers. Many of them are ready and willing to pay for three or five years in advance, but the current VMware model does not support that structure effectively. Because pricing is tied to the U.S. dollar and subject to yearly adjustments, VMware does not lock in pricing for the full term. From a customer’s perspective, this introduces uncertainty and makes procurement more complicated. Ideally, if a price is quoted—for example, $100 per year—it should remain consistent across a multi-year agreement. Customers would be comfortable committing to a five-year term if the price were fixed and predictable. Unfortunately, that flexibility is currently not available across VMware products, whether it is vSphere, VMware Tanzu solutions, or other offerings. For large enterprise environments, one-year commitments are usually not practical. Many enterprise customers prefer longer-term agreements for budgeting and procurement reasons. Even when they are willing to accept the higher cost associated with the core-based licensing model, the lack of a clear multi-year upfront option often becomes a deal-breaker.

Quotes from Members

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

Pros

"The best features EMQX offers in my experience are that it can send messages for a large number of customers with a very high message-per-second rate while consuming low resources."
"EMQX is a solid open-source project for making IoT devices connect anywhere in the world."
"The outcomes from using EMQX are very cost-saving for us because we previously used the MQTT Mosquitto broker, and when I compare Mosquitto with EMQX, EMQX is far better than Mosquitto and other protocols."
"EMQX will boost your product sampling rate and transmission so that you can achieve a large amount of data without any loss while transmitting through the internet."
"The loading speed is very good."
"Pivotal Greenplum's shared-nothing architecture."
"Scalable (Massive) Parallel Processing (MPP) – The ability to bring to bear large amounts of compute against large data sets with Greenplum and the EMC DCA has proven itself to be very effective."
"With VMware Tanzu Greenplum, one can make a huge database table and analyze the queries by adding in the SQL command. Some hint or command for the query goes over the multi-parallel execution."
"RabbitMQ helped us build a database synchronization framework that allowed us to transfer our clients data to our cloud based data processing centers."
"Loading batch data has really improved the efficiency of our organization."
"The most valuable feature for me is that it is open source. The licensing costs are really low and they are transparent."
"RabbitMQ helped us develop a highly scalable system by decoupling the front end and back end, easily withstanding and passing stress and load testing with more than 10K API calls while providing message queuing and a distributed environment."
 

Cons

"To improve EMQX, I think it should reduce costs, save time when sending messages, and improve reliability."
"EMQX is a good MQTT broker but the historian is simple."
"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."
"If you want to improve further, the SSL certificate and TLS certificate have overhead in serverless EMQX."
"We needed to configure additional plugins. While it was relatively easy to do this on-premises, it became more challenging in the cloud."
"The ongoing response from their support on certain technical issues has been slow. It would help if we can have a faster turn-around here."
"We had several de-clustering problems."
"I was struggling with installing a few things. It would be good if was somewhat similar to RedHat. There should be more documentation regarding installation troubleshooting."
"VMware RabbitMQ's configuration process could be easier to understand."
"There are a lot of areas that can be improved. The bug fixes come as many patches like a start up instead of having scheduled release with proper improvements."
"We would like to see Greenplum maintain a closer relationship with and parity to features implemented in PostgreSQL."
"The fact GreenPlum is using an older version of Postgres means developers coming from other products will find many missing features in PostgreSQL, features which you would assume are standard."
