Kafka is an open-source tool for handling incoming streams of data. Like virtually all powerful tools, it’s somewhat hard to set up and manage. Today, Amazon’s AWS is making this all a bit easier for its users with the launch of Amazon Managed Streaming for Kafka. That’s a mouthful, but it’s essentially Kafka as a fully managed, highly available service on AWS. It’s now available on AWS as a public preview.
As AWS CTO Werner Vogels noted in his AWS re:Invent keynote, Kafka users traditionally had to do a lot of heavy lifting to set up a cluster on AWS and to ensure that it could scale and handle failures. “It’s a nightmare having to restart all the cluster and the main nodes,” he said. “This is what I would call the traditional heavy lifting that AWS is really good at solving for you.”
It’s interesting to see AWS launch this service, given that it already offers a very similar tool in Kinesis, a tool that also focuses on ingesting streaming data. There are plenty of applications on the market today that already use Kafka, and AWS is clearly interested in giving those users a pathway to either move to a managed Kafka service or to AWS in general.
As with all things AWS, the pricing is a bit complicated, but a basic Kafka instance will start at $0.21 per hour. You’re not likely to just use one instance, so for a somewhat useful setup with three brokers and a good amount of storage and some other fees, you’ll quickly pay well over $500 per month.
