Room For Improvement

Users seek easier setup, improved UI, better documentation, monitoring, and memory management for Apache Kafka, addressing complexity and scalability.
Azure Stream Analytics needs improved integration, flexibility, UI, job monitoring, Power BI compatibility, and AI-enhanced features for better user experience.
The performance angle is critical, and while it works in milliseconds, the goal is to move towards microseconds.
Technology Leader at eTCaaS
We are always trying to find the best configs, which is a challenge.
Team Lead, Data Engineering at Nesine.com
A more user-friendly interface and better management consoles with improved documentation could be beneficial.
A cost comparison between products is also not straightforward.

Featured Reviews

Bruno da Silva - PeerSpot reviewer
Senior Manager at Timestamp, SA
Have worked closely with the team to deploy streaming and transaction pipelines in a flexible cloud environment
The interface of Apache Kafka could be significantly better. I started working with Apache Kafka from its early days, and I have seen many improvements. The back office functionality could be enhanced. Scaling up continues to be a challenge, though it is much easier now than it was in the beginning.
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.
