Pros & Cons summary

PubSub+ Platform offers seamless installation, flexible topic hierarchy, and features like WAN optimization and HybridEdge. It enables protocol-agnostic message transport and supports real-time access, but faces challenges in usability, deployment complexity, and limited LDAP-based single sign-on. While its event mesh capability and scaling integration are highlights, development requires significant effort, and costs are a concern. Understanding event mesh importance needs clearer communication, and resending past events is not possible.

Prominent pros & cons

PROS

PubSub+ Platform offers extensive WAN optimization enabling send once over a WAN and local distribution to many subscribers.

With its event mesh capabilities, PubSub+ Platform provides a seamless integration strategy in a digital landscape.

The platform allows for scaling with significant market data and messaging spikes, supporting 40% growth effortlessly.

PubSub+ Platform offers a protocol-agnostic message transport fabric supporting various asynchronous messaging protocols like MQ, Kafka, and JMS.

It enables topic-based subscriptions and fanout exchange, enhancing the speed of processing, publishing, and consumption in a hybrid landscape.

CONS

PubSub+ Platform should allow third-party agents to be installed as it is currently quite proprietary.

There is a challenge with Solace's ability to integrate with single sign-on in Active Directory and other tools, as it typically supports only LDAP-based connectivity.

Licensing and cost are major pitfalls of PubSub+ Platform, making it quite expensive compared to competitors like Kafka.

The deployment process of PubSub+ Platform is complex, which needs improvement.

The current max payload size is limited to 5MB; an increase to 100MB or more is suggested for improvements.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

We have requested to be able to get into the payload to do dynamic topic hierarchy building. A current workaround is using the message's header, where the business data can be put into this header and be used for a dynamic topic lookup. I want to see this in action when there are a couple of hundred cases live. E.g., how does it perform? From an administration perspective, is the ease of use there?

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.

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.
