Featured Reviews

Ritik Varshney - PeerSpot reviewer
Enhanced data streaming with reliable features and good analytics
Apache Kafka on Confluent Cloud provides an enhanced level of reliability and resources compared to Apache Kafka alone. It offers more features which are beneficial for our clients, including cluster linking, schema registry, error handling, and dead-letter queues. It significantly improves customer and publisher satisfaction, especially with topic integration and data streaming.

Has small footprint and low maintenance cycles
Pre-installed tools can provide basic training and security measures, which is helpful. However, these tools may not be sufficient to secure your workload fully. That's why it's important to complement them with other specialized security tools to enhance your overall security. Before using Kali Linux, make sure you know its pros and cons. It's a good system to learn because it's the best choice for some situations. It has default firewall settings that block everything by default. It's up to the user to decide how much they want to open up. Learning Kali Linux takes time because it relies on command-line tasks instead of graphical interfaces. Practice is key to becoming comfortable with it.

Quotes from Members

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

Pros

"The product's installation phase is pretty straightforward for us since we know how to use it."
"Confluent Cloud handles data volume pretty well."
"Kafka provides handy properties that allow us to directly configure the data, whether to keep it or discard it after use."
"Overall, I think it's a good experience. Apache Kafka can be quite complex and difficult to maintain on your own, so using Apache Kafka on Confluent Cloud makes it much easier to use it without worrying about setup and maintenance."
"In case of huge transactions on the web or mobile apps, it helps you capture real-time data and analyze it."
"The state-saving feature is very much appreciated. It allows me to rewind a certain process if I see an error and then reprocess it."
"Kafka and Confluent Cloud have proven to be cost-effective, especially when compared to other tools. In a recent BI integration program over the past year, we assessed multiple use cases spanning ship-to-shore and various Azure integrations. Our findings revealed that Confluent Kafka performed exceptionally well, standing out alongside Genesys and Azure Event Hubs. While these three are top contenders, the choice among other tools depends on the specific use case and project requirements. The customer initially used tools like SMQs, FITRA, and Stream for real-time data processing. However, after our recommendation, Confluent Cloud proved to be a superior choice, capable of replacing these three tools and simplifying their data infrastructure. This shift to a single tool, Confluent Cloud, streamlined their operations, making maintenance and management more efficient for their internal projects."
"Apache Kafka on Confluent Cloud is more reliable and frequent to use compared to Apache Kafka."
"The interface is good and straightforward to use."
"Additionally, it now includes comprehensive migration analytics and reporting capabilities."
"We use the product for open-source intelligence and identifying vulnerabilities."
"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"Kali Linux is much better than other OS because it gives you a good set of tools. It is preferred for vulnerability assessments and cybersecurity."
"The solution's stability is very good."
"The solution's most valuable feature is that it is very easy to use."
"In general, Kali Linux is used for hosting applications, developing new applications, and operating systems. It's also used in containers and nodes. The tool offers a smaller footprint than Windows because it lacks the functionality of graphical user interfaces. One advantage of Kali Linux is its lower maintenance requirements than Windows, with slower update cycles and easier maintenance procedures."
 

Cons

"The solution is expensive."
"Maybe in terms of Apache Kafka's integration with other Microsoft tools, our company faced some challenges."
"There are some premium connectors, for example, available in Confluent, which you cannot access in the marketplace, so there are some limitations."
"Some areas for improvement in Apache Kafka on Confluent Cloud include issues faced during migration with Kubernetes pods."
"The administration port could be more extensive."
"There's one thing that's a common use case, but I don't know why it's not covered in Kafka. When a message comes in, and another message with the same key arrives, the first version should be deleted automatically."
"There could be an in-built feature for data analysis."
"Regarding real-time data usage, there were challenges with CDC (Change Data Capture) integrations. Specifically, with PyTRAN, we encountered difficulties. We recommended using our on-premises Kaspersky as an alternative to PyTRAN for that specific use case due to issues with CDC store configuration and log reading challenges with the iton components."
"Unfortunately, my current tool runs on Windows 10, and its use is restricted to enterprise versions. Integrating this tool or similar functionalities into Kali Linux for non-enterprise users would be incredibly valuable."
"I would like to have automation in Kali Linux instead of manually configuring or setting up something in case of an upgrade."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
"The product should improve its security features."
"Any new user or someone without deep expertise won't be able to understand how to scale or manage it"
"The product should integrate AI and GPT capabilities."
"The tool is slightly difficult to learn."
"I would like for them to offer more features for the free version in order for users to test them in their internal environment before purchasing."
 

Pricing and Cost Advice

"Regarding pricing, Apache Kafka on Confluent Cloud is not a cheap tool. The right use case would justify the cost. It might make sense if you have a high volume of data that you can leverage to generate value for the business. But if you don't have those requirements, there are likely cheaper solutions you could use instead."
"I think the pricing is fair, but Confluent requires a little bit more thinking because the price can go up really quickly when it comes to premium connectors."
"I consider that the product's price falls under the middle range category."
"Kali Linux is open source."
"The tool is open-source."
"I have used the free version."
"The price is good because Kali Linux already provides a good bundle of tools."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"Kali Linux offers a perpetual license, meaning you pay for it once and can use it. While free versions of Linux are available, Kali Linux, being an enterprise edition, usually comes with a perpetual license. I rate its pricing a five out of ten."
"It is an open-source tool."
"The licensing fee is expensive compared to other products."
