EMR Serverless now available from AWS

Amazon EMR

Amazon EMR, which is apparently the most popular hosted Hadoop environment in the world, is now widely available as a serverless offering, AWS announced today.

Amazon EMR Serverless will save customers time and money in many different ways, according to AWS. For starters, the new service automatically provides and manages the required basic computing and memory based on the specific frameworks the client uses, such as Apache Spark, Apache Hive, Presto, Flink, or the old MapReduce.

EMR Serverless is also expanding the core cluster up and down, as dictated by changing data volumes and processing requests, the company says. This will help customers prevent a cluster from overcharging to meet peak demand, only to keep it largely idle for long periods of time.

“With EMR Serverless, you can run analytics tasks at any scale, with automatic scaling that resizes resources in seconds to meet changing data volume and processing requirements,” said Channy Yun, AWS’s lead lawyer for developers. -a blog post. “EMR Serverless automatically scales resources up and down to provide exactly the right amount of capacity for your application, and you only pay for what you use.”

To start an EMS Serverless job, customers select the open source framework they want to use, and then launch their application to run either using the APIs, CLI, AWS Management Console, or EMR Studio, says AWS.

EMR Serverless pricing is based on the number of employees the service increases at each stage of the client’s job. Customers are charged for vCPU, memory, and aggregate storage resources used from the moment a worker starts running until they stop, rounded to the nearest second with a minimum of 1 minute, the company says.

EMR Serverless was first unveiled at last year’s Re: Invent 2021 conference, where AWS also unveiled Amazon Redshift Serverless and Amazon MSK (Kafka) Serverless. Prior to the conference, AWS provided a single server-free analytics service for Athena, its hosted Presto environment.

AWS intends to eventually offer server-free versions of all its analytics services, according to Rahul Pathak, AWS’s vice president of analytics. “It requires the client to work less and this is always a gain from the client’s point of view,” said Pathak.
