Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"The most valuable feature of Apache Kafka is the clustering which is very easy to scale and we have multiple servers all over our platforms. It has been useful for stability and performance.""Deployment is speedy.""The most valuable feature is the messaging function and reliability.""Robust and delivers messages quickly.""I like Kafka's flexibility, stability, reliability, and robustness.""The stability is very nice. We currently manage 50 million events daily.""valuable features relate to microservices architecture and working on KStream and KSQL DB as a microservices event bus.""The high availability is valuable. It is robust, and we can rely on it for a huge amount 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.""As of now, the most valuable aspects are the topic-based subscription and the fanout exchange that we are using.""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.""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.""When it comes to granularity, you can literally do anything regarding how the filtering works."

Cons
"The management tool could be improved.""An area for improvement would be growth.""Something that could be improved is having an interface to monitor the consuming rate.""It's not possible to substitute IBM MQ with Apache Kafka because the JMS part is not very stable.""The support on Apache Kafka could be improved.""The initial setup and deployment could be less complex.""While the solution scales well and easily, you need to understand your future needs and prep for the peaks.""Kafka has a lot of monitors, but sometimes it's most important to just have a simple monitor."

More Apache Kafka Cons →

"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?""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.""If you create one event in the past, you cannot resend it.""It could be cheaper. It could also have easier usage. It is a brilliant product, but it is quite complex to use."

Pricing and Cost Advice
  • "The solution is free, it is open-source."
  • "Apache Kafka is free."
  • "The price for the enterprise version is quite high. For on-premise, there is an annual fee, which starts at 60,000 euros, but it is usually higher than 100,000 euros. The cost for a project including the subscription is usually between 100,000 to 200,000 euros. The cost also depends on the level of support. There are two different levels of support."
  • "We use the free version."
  • "This is an open-source version."
  • "It's a bit cheaper compared to other Q applications."
  • "Apache Kafka is an open-sourced solution. There are fees if you want the support, and I would recommend it for enterprises. There are annual subscriptions available."
  • "We are using the free version of Apache Kafka."
  • More Apache Kafka Pricing and Cost Advice →

  • "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.

    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."
