Quotes From Members

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

Pros
"It's very easy to keep to install and it's pretty stable.""Kafka provides us with a way to store the data used for analytics. That's the big selling point. There's very good log management.""The most valuable feature is that it can handle high volume.""Scalability is very good.""It's an open-source product, which means it doesn't cost us anything to use it.""The most valuable feature is the performance.""The most important feature for me is the guaranteed delivery of messages from producers to consumers.""We get amazing throughput. We don't get any delay."

"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.""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.""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.""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.""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.""Guaranteed Messaging allows for us to transport messages between on-prem and the cloud without any loss of data.""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.""When it comes to granularity, you can literally do anything regarding how the filtering works."

Cons
"The third party is not very stable and sometimes you have problems with this component. There are some developments in newer versions and we're about to try them out, but I'm not sure if it closes the gap.""If the graphical user interface was easier for the Kafka administration it would be much better. Right now, you need to use the program with the command-line interface. If the graphical user interface was easier, it could be a better product.""Kafka does not provide control over the message queue, so we do not know whether we are experiencing lost or duplicate messages.""In the next release, I would like for there to be some authorization and HTL security.""The UI is based on command line. It would be helpful if they could come up with a simpler user interface.""Kafka is complex and there is a little bit of a learning curve.""More adapters for connecting to different systems need to be available.""The manageability should be improved. There are lots of things we need to manage and it should have a function that enables us to manage them all cohesively."

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

Pricing and Cost Advice
"Apache Kafka is open-source and can be used free of charge.""Kafka is open-source and it is cheaper than any other product.""Kafka is more reasonably priced than IBM MQ.""The solution is open source; it's free to use.""Apache Kafka is an open-source solution and there are no fees, but there are fees associated with confluence, which are based on subscription.""The solution is free, it is open-source."

"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."

Overview

Apache Kafka is a distributed streaming platform, with the following capabilities:

  • It lets you publish and subscribe to streams of records. In this respect it is similar to a message queue or enterprise messaging system.
  • It lets you store streams of records in a fault-tolerant way.
  • It lets you process streams of records as they occur.

Apache Kafka gets used for two broad classes of application:

  • Building real-time streaming data pipelines that reliably get data between systems or applications.
  • Building real-time streaming applications that transform or react to the streams of data.

PubSub+ is a complete event streaming and management platform for the real-time enterprise.
PubSub+ helps enterprises design, deploy and manage event-driven architectures across hybrid cloud, multi-cloud and IoT environments, so they can be more integrated and event-driven.

The "+" in PubSub+ means it supports a wide range of message exchange patterns beyond publish/subscribe, including request/reply, streaming and replay, as well as different qualities of service, such as best effort and guaranteed delivery. It's available as an appliance, software, and as-a-service. All options offer the same functionality and management experience.

PubSub+ lets users connect event brokers to form an event mesh - an architectural layer that supports dynamically routing events from one application to any other application no matter where those applications are deployed (no cloud, private cloud, public cloud) - so users can connect and orchestrate microservices, push events from on-premesis systems of record to cloud services, and enable digital transformation across LoBs and IoT.

Its APIs supports popular programming languages, with open APIs and protocols to connect to any application, providing a best-in-class approach to messaging to never get locked in to any technology — including the vendor's own.
