Room For Improvement

Apache Kafka on Confluent Cloud needs improvements in integrations, user interface, cost, monitoring, and configuration for enhanced functionality.
Azure Stream Analytics needs improved integration, flexibility, UI, job monitoring, Power BI compatibility, and AI-enhanced features for better user experience.
If it were easier to configure clusters and had more straightforward configuration, high-level API abstraction in the APIs could improve it.

Regarding additional improvements, I would say probably around error handling, where when we encounter errors specific to our response structures and everything, or the tables or anything of that nature, it would be better if we were prompted with better error handling mechanisms.
Lead Software Engineer at a tech vendor with 10,001+ employees
Observability and monitoring are areas that could be enhanced.
Chief Architect at a financial services firm with 10,001+ employees
A cost comparison between products is also not straightforward.
Director, Governance & Infrastructure & Director at VASS
There's setup time required to get it integrated with different services such as Power BI, so it's not a straight out-of-the-box configuration.
Data Strategist, Cloud Solutions Architect at BiTQ
Azure Stream Analytics currently allows some degree of code writing, which could be simplified with low-code or no-code platforms to enhance performance.

Setup Cost

Enterprise users of Apache Kafka on Confluent Cloud find pricing accessible but warn of potential cost surges with added features.
Azure Stream Analytics pricing is competitive, with optimization options, but billing complexity and short free trial need improvement.
I thought Confluent would stop me when I crossed the credits, but it did not, and then I got charged.
Lead Software Engineer at a tech vendor with 10,001+ employees
Choosing between pay-as-you-go or enterprise models can affect pricing, and depending on data volume, charges might increase substantially.
Technical architect at Tech Mahindra
From my point of view, it should be cheaper now, considering the years since its release.
Director, Governance & Infrastructure & Director at VASS
We sell the data analytics value and operational value to customers, focusing on productivity and efficiency from the cloud.

Has unified log streams from multiple systems and accelerated issue tracking through streamlined setup
I think Apache Kafka on Confluent Cloud can be improved by probably working more around Confluent or the tool. In my opinion, it should utilize the response structures in a better way or be able to detect if there is any variable or if there is any data structure that is mismatched, as it would be easier than us manually having to put in the exact name in order for it to match the response. Regarding additional improvements, I would say probably around error handling, where when we encounter errors specific to our response structures and everything, or the tables or anything of that nature, it would be better if we were prompted with better error handling mechanisms. I do not think there are any other improvements Apache Kafka on Confluent Cloud needs, aside from error handling and response structures.
Chandra Mani - PeerSpot reviewer
Technical architect at Tech Mahindra
Has supported real-time data validation and processing across multiple use cases but can improve consumer-side integration and streamlined customization
I widely use AKS, Azure Kubernetes Service, Azure App Service, and there are APM Gateway kinds of things. I also utilize API Management and Front Door to expose any multi-region application I have, including Web Application Firewalls, and many more—around 20 to 60 services. I use Key Vault for managing secrets and monitoring Azure App Insights for tracing and monitoring. Additionally, I employ AI search for indexer purposes, processing chatbot data or any GenAI integration. I widely use OpenAI for GenAI, integrating various models with our platform. I extensively use hybrid cloud solutions to connect on-premise cloud or cloud to another network, employing public private endpoints or private link service endpoints. Azure DevOps is also on my list, and I leverage many security concepts for end-to-end design. I consider how end users access applications to data storage and secure the entire platform for authenticated users across various use cases, including B2C, B2B, or employee scenarios. I also widely design multi-tenant applications, utilizing Azure AD or Azure AD B2C for consumers. Azure Stream Analytics reads from any real-time stream; it's designed for processing millions of records every millisecond. They utilize Event Hubs for this purpose, as it allows for event processing. After receiving data from various sources, we validate and store it in a data store. Azure Stream Analytics can consume data from Event Hubs, applying basic validation rules to determine the validity of each record before processing.
