Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"I think the whole product is useful. Their database and all is very good, and the product is fine. The fact that it ensures message delivery is probably the most important thing. I also like that you're able to trace and track everything. If it doesn't arrive at the destination, it will go back to the queue, and no message will be lost.""There is no dependency on the end party service's run status.""This solution has improved and influenced the communication between different applications, then standardized that communication.""It offers better reliability and monitoring compared to other tools.""The solution allows one to easily configure an IBM MQQueueManager.""The solution can scale well.""RabbitMQ and Kafka require more steps for setup than IBM MQ. Installation of the IBM product is very simple.""The scalability of IBM MQ is good."

"We've built a lot of products into it and it's been quite easy to feed market data onto the systems and put entitlements and controls around that. That was a big win for us when we were consolidating our platforms down. Trying to have one event bus, one messaging bus, for the whole globe, and consolidate everything over time, has been key for us. We've been able to do that through one API, even if it's across the different languages.""This solution reduces the latency to access changes in real-time and the effort required to onboard a new subscriber. It also reduces the maintenance of each of those interfaces because now the publisher and subscribers are decoupled. Event Broker handles all the communication and engagement. We can just push one update, then we don't have to know who is consuming it and what's happening to that publication downstream. It's all done by the broker, which is a huge benefit of using Event Broker.""The event portal and the diversity of deployment options in a hybrid landscape are the most valuable features.""Guaranteed Messaging allows for us to transport messages between on-prem and the cloud without any loss of data.""As of now, the most valuable aspects are the topic-based subscription and the fanout exchange that we are using.""The most useful features has been the WAN optimization and probably the HybridEdge, which requires some third-party adapters or plugins. The idea that we can position Solace as a protocol-agnostic message transport fabric is key to our company having all manners of asynchronous messaging protocols from MQ, Kafka, JMS, etc. I really like the WAN optimization: Send once over a WAN, then distribute locally as many times as there are subscribers.""One of the main reasons for using PubSub+ is that it is a proper event manager that can handle events in a reactive way.""The topic hierarchy is pretty flexible. Once you have the subject defined just about anybody who knows Java can come onboard. The APIs are all there."

Cons
"There are things within the actual product itself that can be improved, such as limitations on message length, size, etc. There is no standardized message length outside of IBM. Each of the implementations of the MQ series or support of that functionality varies between various suppliers, and because of that, it is very difficult to move from one to the other. We have IBM MQ, but we couldn't use it because the platform that was speaking to MQ didn't support the message length that was standard within IBM MQ. So, we had to use a different product to do exactly the same thing. So, perhaps, there could be more flexibility in the standards around the message queue. If we had been able to increase the message queue size within the IBM MQ implementation, we wouldn't have had to go over to another competing product because the system that was using MQ messaging required the ability to hold messages that were far larger than the IBM MQ standard. So, there could be a bit more flexibility in the structuring. It has as such nothing to do with the IBM implementation of MQ. It is just that the standard that is being put out onto the market doesn't actually stipulate those types of things.""Sometimes, not all messages are consumed in the queues. File transfers need improvement.""The product does not allow users to access data from API or external networks since it can only be used in a closed network, making it an area where improvements are required.""At a recent conference, I went to a presentation that had the latest version and it has amazing stuff that's coming out. So, I am excited to use those, specifically surrounding the web console and the fact that it's API integrated.""It could get a face lift with a modern marketing campaign.""SonicMQ CAA (continuous availability architecture) functionality on auto failover and data persistence should be made available without a shared drive, as it exists in multi-instance queue managers.""It would be nice if we could use the cluster facilities because we are doing active/passive configuration use.""They have provided a Liberty Profile in the Web Console for administration, and that could be further enhanced. It is not fit for use by an enterprise. They have to get rid of their WebSphere process and develop a front-end on Node.js or the like."

"The section on observability pertains to understanding the functioning of an event crash. Instead of focusing on how the crash occurs, attention is given to the observable aspects, such as a memory pipeline where one person pushes messages and another reads them. However, this pipeline often encounters issues, such as the reader being unavailable, causing the system to become stuck and preventing the messages from moving forward. This can lead to the pipeline being permanently stalled.""If you create one event in the past, you cannot resend it.""I would like them to design topic and queue schemas, mapping them to the enterprise data structure.""Some of the feature's gaps with some of the open-source vendors have been closed in a lot of ways. Being more agile and addressing those earlier could be an area for improvement.""It could be cheaper. It could also have easier usage. It is a brilliant product, but it is quite complex to use.""The ease of management could be approved. The GUI is very good, but to configure and manage these devices programmatically in the software version is not easy. For example, if I would like to spin up a new software broker, then I could in theory use the API, but it would require a considerable amount of development effort to do so. There should be a tool, or something that Solace supports, that we could use for this, e.g., a platform like Terraform where we could use infrastructure as code to configure our source appliances.""We've pointed out some things with the DMR piece, the event mesh, in edge cases where we could see a problem. Something like 99 percent of users wouldn't ever see this problem, but it has to do with if you get multiple bad clients sending data over a WAN, for example. That could then impact other clients.""The licensing and the cost are the major pitfalls."

Pricing and Cost Advice
  • "It's super expensive, so ask them if they can consolidate some other licensing costs. But, IBM is IBM, so I guess we'll pay for it."
  • "IBM MQ has a flexible license model based on the Processor Value Unit (PVU) and I recommend it."
  • "Use the new and lightweight version (Liberty) to lower licensing costs. It is also easier to upgrade/maintain."
  • "I think the pricing is reasonable, especially with IIB as a part of it."
  • "Pricing could be better, as with all IBM products. But their performance in production, along with security and scalability, will pay returns in the long run."
  • "99.999 percent availability for less than a penny per message over the past 25 years. IBM MQ is the cheapest software in the IBM software portfolio, and it is one of the best."
  • "IBM MQ appliance has pricing options, but they are costly."
  • "In terms of cost, IBM MQ is slightly on the higher side."
  • More IBM MQ Pricing and Cost Advice →

  • "There are different tiers where you can choose what would work for you. As a customer, you need to know roughly how many messages a month you will use."
  • "We have been really happy with the product licensing rates. It has been free for us, up to a 100,000 transactions per second, and all we have to do is pay for support. Making their product available and accessible to us has not been a problem at all."
  • "Having a free version is critical for our technology operations use case. This is primarily because our technology operations team is a cost center in our company. They are not profit drivers and having a free version for installation will probably meet our needs. Even for production, it'll support up to a 100,000 messages per second. I don't think in technology operations that we have that many events and alerts from our detection tools. Even if I have 20 or 30 event detection products out there, they're only going to publish the things which are critical or warnings. I don't think we'll ever reach a 100,000 messages per second."
  • "Having a free version of the solution was a big, important part of our decision to go with it. This was the big driver for us to evaluate Solace. We started using it as the free version. When we felt comfortable with the free version, that is when we bought the enterprise version."
  • "The pricing and licensing were very transparent and well-communicated by our account manager."
  • "We are looking for something that will add value and fit for purpose. Freeware is good if you want to try something quickly without putting in much money. However, as far as our decision is concerned, I don't think it helps. At the end of the day, if we are convinced that a capability is required, we will ask for the funding. Then, when the funding is available, we will go for an enterprise solution only."
  • "The licensing is dependent on the volume that is flowing. If you go for their support services, it will cost some more money, but I think it is worth it, especially if you are just starting your journey."
  • "It could be cheaper. Its licensing is on a yearly basis."

      Reviews from Real Users

      Below are some reviews and helpful feedback written by IBM MQ users who are currently using the solution.

      PeerSpot user Sunil S., a manager at a financial services firm, explains that they never lose messages are never lost in transit, mentioning that he can store messages and forward them as required: "Whenever payments are happening, such as incoming payments to the bank, we need to notify the customer. With MQ we can actually do that asynchronously. We don't want to notify the customer for each and every payment but, rather, more like once a day. That kind of thing can be enabled with the help of MQ."

      Another PeerSpot reviewer, Luis L. who is a solutions director at Thesys Technologies, says that IBM MQ is a valuable solution and is "A stable and reliable software that offers good integration between different systems."

      The head of operations at a financial services firm notes that "I have found the solution to be very robust. It has a strong reputation, is easy to use, simple to configure in our enterprise software, and supports all the protocols that we use."

      In addition, a Software Engineer at a financial services firm praises the security benefits of it and states that “it has the most security features I've seen in a communication solution. Security is the most important thing for our purposes."

    Solace PubSub+ Event Broker is a serverless, scalable technology that efficiently streams events throughout all sorts of environments: within the cloud, on-premises, and IoT. The technology is based on the publish/subscribe model of communication. The “+” in the solution’s name alludes to its support of a wide spectrum of message exchange patterns beyond the publish/subscribe model; it supports queueing, streaming, and request/reply. The “+” also alludes to the fact that the solution supports a range of different qualities of service. PubSub+ Event Broker can be managed and monitored with a single administration interface.

    PubSub+ Event Broker uses robust, battle-tested, and reliable event broker technology. It allows users to tie their architectures together to benefit from the best of all technologies, including legacy ESBs/messaging, DB system of record on-prem, cloud-native services, and Kafka clusters as endpoints.

    PubSub+ Event Broker lets you connect event brokers to form an event mesh (an architecture layer) which allows you to route events in a dynamic way between applications, regardless of where those applications are deployed (for example, from public-cloud, private-cloud, or no-cloud).

    Reviews from Real Users

    PubSub+ Event Broker stands out among its competitors for a number of reasons. Two major ones are its ability to communicate with numerous subscribers and its scalability. PeerSpot users take note of the advantages of these features in their reviews:

    Jitendra J., a websphere MQ specialist at a maritime company, notes, “The way we can replicate information and send it to several subscribers is most valuable. It can be used for any kind of business where you've got multiple users who need information. Any company, such as LinkedIn, with a huge number of subscribers and any business, such as publishing, supermarket, airline, or shipping can use it.”

    The head of enterprise architecture and digital innovation at a tech vendor writes, “This solution reduces the latency to access changes in real-time and the effort required to onboard a new subscriber. It also reduces the maintenance of each of those interfaces because now the publisher and subscribers are decoupled. Event Broker handles all the communication and engagement.”

    Another PeerSpot user, who is a senior project manager at a financial services firm, describes, "Going from something where we had outages and capacity issues constantly to a system that was able to scale with the massive market data and messaging spikes that happened during the initial stages of the COVID crisis in March, we were able to scale with 40 plus percent growth in our platform over the course of days."
