Managed cloud databases have reduced operational effort and now support faster feature delivery
Aiven Platform could be improved by offering more detailed monitoring and analytics, additional customization plan options, enhanced cost operation insights, and more comprehensive data for advanced use cases. On a day-to-day basis, I highlight the need for improving dashboard navigation by providing clear cost visibility. There are navigational complexities that exist. If you can provide clear cost visibility, it will help reduce friction and improve the user experience. Regarding Aiven Platform's AI capabilities, I think it could improve by providing more granular role-based access control, enhancing audit logging, clearer compliance reporting, and more centralized policy management for governance and security.

The solution can mimic other APIs without changing a line of code
The solution operates as a classic message broker but also as a streaming platform. It operates differently than a traditional streaming platform with storage and computing handled separately. It scales easier and better than Kafka which can be stubborn. You can even make it act like Kafka because it understands Kafka APIs. There are even companies that will sell you Kafka but underneath it is Apache Pulsar. The solution is very compatible because it can mimic other APIs without changing a line of code.

Quotes from Members

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

Pros

"Aiven Platform's cloud flexibility helps my team substantially through seamless migration from one cloud to another, and it provides 99.99% uptime."
"Aiven Platform delivers highly accurate and reliable outputs with consistent performance, and its managed services, monitoring, and high availability features help to ensure data integrity and minimize downtime, highlighting the accuracy and reliability of the output."
"Based on my experience with Aiven Platform, the best feature it offers is Apache Kafka, which is top-notch and one of the best services I have used."
"What I like best about the tool is that the process for the services is faster compared to other methods. It's easier to use because Aiven for Apache Kafka handles the maintenance, so we have less to manage. We only use Kafka to manage its connectivity."
"The performance of Aiven Platform is quite good, as I have not seen any downtime, and it is very reliable, with backups in place, allowing me to fetch data without experiencing any high latency, even as a free tier user."
"One of the most valuable features of Aiven Platform is that it handles the upgrades for us seamlessly, saving us time that would be spent on routine upgrades."
"The solution operates as a classic message broker but also as a streaming platform."
 

Cons

"Regarding needed improvements, I find the support and documentation a bit lacking in detail, and sometimes it takes long to get replies when I need support, which can be a challenge."
"One challenge we face is when we want to update the version, for example, from 3.6 to 3.7. It will spawn new nodes, and then there's rebalancing and syncing from other brokers. There's high CPU usage during this process, so the solution can't be used for a while, causing some downtime in our services. To tackle this challenge, we schedule maintenance updates during low-traffic periods when there's less risk and fewer users use the services."
"I would really like to see Aiven Platform add a user interface for database backups, as this would eliminate the need for a third-party solution."
"Documentation is poor because much of it is in Chinese with no English translation."
