Data streaming transforms real-time data movement with impressive scalability
I worked with Apache Kafka for customers in the financial industry and OTT platforms. They use Kafka particularly for data streaming. Companies offering movie and entertainment as a service, similar to Netflix, use Kafka Apache Kafka offers unique data streaming. It allows the use of data in…
Gustavo-Barbosa Dos Santos - PeerSpot reviewer
Has good technical support services and a valuable feature for real-time data streaming
Implementing Confluent's schema registry has significantly enhanced our organization's data quality assurance. It helps us understand the various requirements of multiple customers and validates the information for different versions. We can automate the tasks using Confluent Kafka. Thus, it guarantees us the data quality and maintains the integrity of message contracts.

Quotes from Members

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

Pros

"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."
"Apache Kafka is effective when dealing with large volumes of data flowing at high speeds, requiring real-time processing."
"Apache Kafka is an open-source solution that can be used for messaging or event processing."
"The high availability is valuable. It is robust, and we can rely on it for a huge amount of data."
"The most valuable feature is the messaging function and reliability."
"This is a system for email and other small devices. There has been a relay of transactions continuously over the last two years it has been in production."
"It is a stable solution...A lot of my experience indicates that Apache Kafka is scalable."
"Apache Kafka has good integration capabilities and has plenty of adapters in its ecosystem if you want to build something. There are adapters for many platforms, such as Java, Azure, and Microsoft's ecosystem. Other solutions, such as Pulsar have fewer adapters available."
"Their tech support is amazing; they are very good, both on and off-site."
"The monitoring module is impressive."
"A person with a good IT background and HTML will not have any trouble with Confluent."
"One of the best features of Confluent is that it's very easy to search and have a live status with Jira."
"We mostly use the solution's message queues and event-driven architecture."
"The design of the product is extremely well built and it is highly configurable."
"Our main goal is to validate whether we can build a scalable and cost-efficient way to replicate data from these various sources."
"The client APIs are the most valuable feature."
 

Cons

"The UI used to access Kafka topics can be further improved."
"The management tool could be improved."
"The solution can improve by having automation for developers. We have done many manual calculations and it has been difficult but if it was automated it would be much better."
"The user interface is one weakness. Sometimes, our data isn't as accessible as we'd like. It takes a lot of work to retrieve the data and the index."
"Some vendors don't offer extra features for monitoring."
"The solution's initial setup process was complex."
"One complexity that I faced with the tool stems from the fact that since it is not kind of a stand-alone application, it won't integrate with native cloud, like AWS or Azure."
"The initial setup and deployment could be less complex."
"There is no local support team in Saudi Arabia."
"The Schema Registry service could be improved. I would like a bigger knowledge base of other use cases and more technical forums. It would be good to have more flexible monitoring features added to the next release as well."
"They should remove Zookeeper because of security issues."
"Currently, in the early stages, I see a gap on the security side. If you are using the SaaS version, we would like to get a fuller, more secure solution that can be adopted right out of the box. Confluence could do a better job sharing best practices or a reusable pattern that others have used, especially for companies that can not afford to hire professional services from Confluent."
"Confluence could improve the server version of the solution. However, most companies are going to the cloud."
"It could be more user-friendly and centralized. A way to reduce redundancy would be helpful."
"The formatting aspect within the page can be improved and more powerful."
"It could have more themes. They should also have more reporting-oriented plugins as well. It would be great to have free custom reports that can be dispatched directly from Jira."
 

Pricing and Cost Advice

"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."
"Apache Kafka is open-source and can be used free of charge."
"I rate Apache Kafka's pricing a five on a scale of one to ten, where one is cheap and ten is expensive. There are no additional costs apart from the licensing fees for Apache Kafka."
"The solution is open source; it's free to use."
"The price of the solution is low."
"It's a bit cheaper compared to other Q applications."
"Apache Kafka is free."
"When starting to look at a distributed message system, look for a cloud solution first. It is an easier entry point than an on-premises hardware solution."
"Confluent is expensive, I would prefer, Apache Kafka over Confluent because of the high cost of maintenance."
"Confluent has a yearly license, which is a bit high because it's on a per-user basis."
"The pricing model of Confluent could improve because if you have a classic use case where you're going to use all the features there is no plan to reduce the features. You should be able to pick and choose basic services at a reduced price. The pricing was high for our needs. We should not have to pay for features we do not use."
"Confluent is highly priced."
"Confluent is an expensive solution as we went for a three contract and it was very costly for us."
"It comes with a high cost."
"Regarding pricing, I think Confluent is a premium product, but it's hard for me to say definitively if it's overly expensive. We're still trying to understand if the features and reduced maintenance complexity justify the cost, especially as we scale our platform use."
"You have to pay additional for one or two features."
