Offers a seamless way to decouple applications, providing impressive performance and flexibility

Regarding improving the PubSub+ Platform, I'm not sure about the pricing aspect, but I heard that it is quite expensive compared to Kafka. That's the only concern I can mention; otherwise, it was as impressive as Kafka, better than Kafka based on my experience working on the Solace and Kafka white paper.

A solution with useful windowing features and great for operations and marketing

The persistence could be better. Although ESP is designed for in-memory processing, it would be better if the solution is enhanced or improved on the persistence of the data that is kept in the memory. For example, if one server goes down and the information is stored in the memory, it is lost. Therefore, the persistence needs to be improved so that if there are more cases where the server is down, the information and data can still be intact.

Quotes from Members

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

Pros

"We like the seamless flexibility in protocol exchange offering without writing a code."

"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 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."

"In my assessment of Solace against other products — as I was responsible for evaluating various products and bringing the right tool into companies in the past — I worked with multiple platforms like RabbitMQ, Confluent, Kafka, and various other tools in the market. But I found the event mesh capability to be a very interesting as well as fulfilling capability, towards what we want to achieve from a digital-integration-strategy point of view... It's distributed, yet it is intelligently connected. It can also span and I can plug and play any number of brokers into the event mesh, so it's a great deal. That's a differentiator."

"I rate the PubSub+ Platform a 9 out of 10."

"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."

"One of the main reasons for using PubSub+ is that it is a proper event manager that can handle events in a reactive way."

More PubSub+ Platform pros

"The solution is beneficial on an enterprise level."

Cons

"The solution could be improved by enhancing the message pooling size for persistent messages to handle both small and large messages effectively."

"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."

"I would like them to design topic and queue schemas, mapping them to the enterprise data structure."

"It could be cheaper. It could also have easier usage. It is a brilliant product, but it is quite complex to use."

"I heard that it is quite expensive compared to Kafka."

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

"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."

"One of the areas of improvement would be if we could tell the story a bit better about what an event mesh does or why an event mesh is foundational to a large enterprise that has a wide diversity of applications that are homegrown and a small number off the shelf."

More PubSub+ Platform cons

"The persistence could be better."

Pricing and Cost Advice

"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."

"The price of the solution is expensive."

"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."

"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 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."

"I would rate the product's pricing a ten out of ten."

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