Executive SummaryUpdated on Jan 27, 2025

IBM Event Streams and PubSub+ Platform compete in the event streaming domain, offering reliable, scalable messaging systems. PubSub+ Platform appears to have the advantage due to its robust features and high-performance metrics, justifying a potentially higher cost.

Features: IBM Event Streams integrates seamlessly with Kafka, ensures strong message durability, and handles data efficiently. PubSub+ Platform supports multi-protocol message streaming, dynamic event broker scaling, and advanced analytics, offering extensive support for diverse messaging environments and comprehensive event management.

Ease Of Deployment and Customer Service: IBM Event Streams offers straightforward cloud and on-premises deployment with comprehensive documentation and technical support. PubSub+ Platform provides flexible deployment options including cloud, hybrid, and enterprise, backed by robust customer service.

Easy to set up with good support and good routing scenarios

The triggering and the events that they have triggered as well as the route of the message according to the events are very useful. The triggering scenarios and routing scenarios are all good. It's a very useful solution for financial institutions. The initial setup is pretty straightforward. The stability has been good. I've found the product to be scalable. Technical support is responsive.

Performs well, high availability, and helpful support

We use approximately four people for the maintenance of the solution. My advice to others is this solution has high throughput and is used for many stock exchanges. For business critical use cases, such as processing financial transactions at a quick speed, I would recommend this solution. I rate PubSub+ Event Broker an eight out of ten.

Quotes from Members

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

Pros

"I'm an administrator, and what I like most is the interface, the security, and the storage."

"The stability has been good."

"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."

"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."

"When it comes to granularity, you can literally do anything regarding how the filtering works."

"When we went to add another installation in our private cloud, it was easy. We received support from Solace and the install was seamless with no issues."

"The event portal and the diversity of deployment options in a hybrid landscape are the most valuable features."

"As of now, the most valuable aspects are the topic-based subscription and the fanout exchange that we are using."

"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."

"Some valuable features include reconnecting topics, placing queues, and direct connections to MongoDB. The platform provides a dashboard to monitor the status of messages, such as how many have been processed or delivered, which is helpful for tracking performance."

"Guaranteed Messaging allows for us to transport messages between on-prem and the cloud without any loss of data."

More PubSub+ Platform pros

Cons

"In the next release, I would like to see the GUI allow you to configure the security section."

"The product's interface needs improvement."

"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."

"The deployment process is complex."

"The product should allow third-party agents to be installed. Currently, it is quite proprietary."

"A challenge we currently have is Solace's ability to integrate with single sign-on in our Active Directory and other single sign-on tools and platforms that any company would have. It's important for the platforms to work. Typically, they support only LDAP-based connectivity to our SQL Servers."

"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."

"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 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."

"The integrations could improve in PubSub+ Event Broker."

More PubSub+ Platform cons

Pricing and Cost Advice

"The pricing needs to be improved."

"The platform is averagely priced."

"It could be cheaper. Its licensing is on a yearly basis."

"The price of PubSub+ Event Broker is reasonable for the capability it offers. However, when compared to others solutions on the market it is expensive."

"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."

"The price of the solution is expensive."

"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."

"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."

"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."

"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."
