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…

Great tool for sharing knowledge, internal communication and allows for real-time collaboration on pages
Confluence is easy to use and modify. However, sometimes there are too many pages. We have to reorganize the folder or parent account. Since everyone can create a page, the same knowledge might be created in multiple places by different people. This leads to redundancy and makes it difficult to find information. It's not centralized. So it could be more user-friendly and centralized. A way to reduce redundancy would be helpful. It's very easy to use, so everyone can create knowledge. But it would be good to synchronize and organize that information a bit better. Another improvement would be in Confluence search. You can search for keywords, but it's not like AI, not even ChatGPT or OpenAI. It would be nice to get more relevant or organized answers. If you're outside the company, you just get some titles containing the keyword you input. But if Confluence were like a database, you could input something and get a well-organized search offering from multiple pages.

Quotes from Members

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

Pros

"The connectors provided by the solution are valuable."
"The stream processing is a very valuable aspect of the solution for us."
"Deployment is speedy."
"Apache Kafka is very fast and stable."
"I use it for real-time processing workloads. So, in some instances, it's like IoT data. We need to put it into a data lake."
"The solution is very scalable. We started with a cluster of three and then scaled it to seven."
"The main advantage is increased reliability, particularly with regard to data and the speed with which messages are published to the other side."
"I have seen a return on investment with this solution."
"The design of the product is extremely well built and it is highly configurable."
"The documentation process is fast with the tool."
"Our main goal is to validate whether we can build a scalable and cost-efficient way to replicate data from these various sources."
"Confluent facilitates the messaging tasks with Kafka, streamlining our processes effectively."
"We mostly use the solution's message queues and event-driven architecture."
"Kafka Connect framework is valuable for connecting to the various source systems where code doesn't need to be written."
"The client APIs are the most valuable feature."
"Implementing Confluent's schema registry has significantly enhanced our organization's data quality assurance."
 

Cons

"More adapters for connecting to different systems need to be available."
"The solution's initial setup process was complex."
"Prioritization of messages in Apache Kafka could improve."
"We cannot apply all of our security requirements because it is hard to upload them."
"It’s a trial-and-error process with no one-size-fits-all solution. Issues may arise until it’s appropriately tuned."
"There is a lot of information available for the solution and it can be overwhelming to sort through."
"Kafka has some limitations in terms of queue management."
"The UI used to access Kafka topics can be further improved."
"They should remove Zookeeper because of security issues."
"It could be improved by including a feature that automatically creates a new topic and puts failed messages."
"The formatting aspect within the page can be improved and more powerful."
"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."
"We continuously face issues, such as Kafka being down and slow responses from the support team."
"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."
"there is room for improvement in the visualization."
"There is no local support team in Saudi Arabia."
 

Pricing and Cost Advice

"Apache Kafka is an open-source solution."
"Kafka is more reasonably priced than IBM MQ."
"This is an open-source version."
"Kafka is an open-source solution, so there are no licensing costs."
"The cost can vary depending on the provider and the specific flavor or version you use. I'm not very knowledgeable about the pricing details."
"It is approximately $600,000 USD."
"The price of Apache Kafka is good."
"I would not subscribe to the Confluent platform, but rather stay on the free open source version. The extra cost wasn't justified."
"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."
"On a scale from one to ten, where one is low pricing and ten is high pricing, I would rate Confluent's pricing at five. I have not encountered any additional costs."
"Confluent is an expensive solution."
"Confluent has a yearly license, which is a bit high because it's on a per-user basis."
"You have to pay additional for one or two features."
"It comes with a high cost."
"The solution is cheaper than other products."
"Confluence's pricing is quite reasonable, with a cost of around $10 per user that decreases as the number of users increases. Additionally, it's worth noting that for teams of up to 10 users, the solution is completely free."
