Study Notes
- ACUS EMR (Amazon EMR) is a cloud-based big data platform.
- It is designed to process and analyze massive datasets.
- It uses open-source frameworks like Apache Spark, Hadoop, Presto, and Hive.
- It provides scalable, cost-effective, and high-performance solutions.
- These solutions are for data analytics, machine learning, and real-time data processing.
Cluster Types in ACUS EMR
- ACUS EMR supports different cluster configurations.
- The goal is to optimize performance and cost.
- On-Demand Clusters are suitable for temporary workloads and batch processing, and are charged based on usage duration.
- Persistent Clusters are always running for continuous processing and analytics, and are used for long-term ETL pipelines.
- Spot Instance Clusters uses AWS Spot Instances to minimize costs, and is best for fault-tolerant workloads where cost savings are a priority.
- Auto-Scaling Clusters automatically adjusts instance counts based on workload demand, which helps optimize performance and cost efficiency.
Storage Options
- HDFS (Hadoop Distributed File System) stores temporary data within the cluster.
- Amazon S3 serves as durable and cost-effective external storage.
- EMRFS (EMR File System) extends HDFS capabilities using Amazon S3.
- EBS (Elastic Block Store) provides additional storage for nodes.
- Glue Data Catalog helps in metadata management for querying structured data.
Scaling Options
- Manual Scaling involves users manually adding or removing nodes based on workload.
- Auto-Scaling automatically adjusts cluster size based on predefined rules.
- Instance Fleets allows mixing different instance types for cost optimization.
Deployment Options
- EMR on EC2 (Traditional Deployment) runs clusters on Amazon EC2 instances with full customization.
- EMR on AWS Outposts deploys EMR clusters in on-premises environments for hybrid cloud setups.
- EMR Serverless eliminates cluster management by automatically provisioning resources as needed.
- EMR on EKS (Elastic Kubernetes Service) runs EMR workloads in a containerized Kubernetes environment.
- Each deployment option provides flexibility depending on workload demands, cost considerations, and infrastructure preferences.
