Alibaba Cloud Message Queue for Apache Kafka

What Alibaba Cloud Message Queue for Apache Kafka is

Alibaba Cloud Message Queue for Apache Kafka is a cloud, web-based messaging service for stream processing. It uses at-least-once delivery and supports client applications written in Java, Python, C++, Go, PHP, Ruby, Node.js, and C#. The service has three listed billing approaches, with no stated prices and no free plan. Serverless usage is metered hourly, scales automatically, and is charged according to consumed resources. Subscription provides prepaid capacity for a fixed duration, available for one month, multiple months, or multiple years. Pay-as-you-go is settled hourly while an instance exists, with listed billing factors including traffic specification, storage, partitions, and optional Internet traffic. This gives teams different ways to provision Kafka messaging: resource-based automatic scaling, fixed-term prepaid capacity, or hourly instance billing. The product is intended for web-based deployments that need stream-processing messaging and at-least-once delivery.
