6. Step-by-Step Guide: Creating an EMR Serverless Application
In this example, we'll walk through creating an EMR Serverless application for data processing and transformation using Apache Spark:
- Create an IAM Role: Create an IAM role with the necessary permissions to access the AWS services your EMR Serverless application will use.
- Create an S3 Bucket: Create an S3 bucket to store your input and output data.
- Create a Lambda Function: Create a Lambda function to trigger your EMR Serverless application.
-
Create an EMR Serverless Application: In the AWS Management Console, navigate to the EMR Service and create a new EMR Serverless application.
- Choose Apache Spark as the big data framework.
- Specify the IAM role you created in step 1.
- Configure the compute resources and storage settings.
- Configure the Application: Upload your Spark application jar file and configure the necessary application properties, such as the input and output data locations in the S3 bucket.
- Test the Application: Test your EMR Serverless application by running it with a small dataset.
- Monitor the Application: Monitor the application's progress and resource usage in the EMR Service.
7. Pricing Overview
EMR Serverless pricing is based on the resources consumed by your application, including compute instances, storage, and data processing. You can estimate your costs using the AWS Pricing Calculator or the EMR Serverless pricing page.
Common pricing pitfalls to avoid include:
- Underestimating resource requirements: Ensure that you properly configure your compute resources and storage to handle your workload's demands.
