Cluster Management
Cluster management in Amazon EMR involves creating, configuring, and monitoring clusters to run big data processing applications. As an AWS Certified Solutions Architect, you must understand how to create and configure clusters for optimal performance, durability, and cost-effectiveness. EMR lets you create a cluster with specified configurations for your processing needs, such as EC2 instance types, software versions, and security settings. You can also configure Auto Scaling policies to automatically adjust the size of your cluster based on your workload. Operational logging, monitoring, and troubleshooting tools like CloudWatch and CloudTrail enable you to track the cluster's performance and identify any issues. Additionally, EMR provides features like instance fleets and spot instances that allow you to optimize resource allocation and cost.
