Amazon EMR
Easily Run and Scale Apache Spark, Hadoop, HBase, Presto, Hive, and other Big Data Frameworks
Amazon EMR provides a managed Hadoop framework that makes it easy, fast, and cost-effective to process vast amounts of data across dynamically scalable Amazon EC2 instances. You can also run other popular distributed frameworks such as Apache Spark, HBase, Presto, and Flink in Amazon EMR, and interact with data in other AWS data stores such as Amazon S3 and Amazon DynamoDB.
Amazon EMR securely and reliably handles a broad set of big data use cases, including log analysis, web indexing, data transformations (ETL), machine learning, financial analysis, scientific simulation, and bioinformatics.
Benefits
Easy to use
You can launch an Amazon EMR cluster in minutes. You don’t need to worry about node provisioning, cluster setup, Hadoop configuration, or cluster tuning. Amazon EMR takes care of these tasks so you can focus on analysis.
Low cost
Amazon EMR pricing is simple and predictable: You pay a per-second rate for every second used, with a one-minute minimum charge. You can launch a 10-node Hadoop cluster for as little as $0.15 per hour. Because Amazon EMR has native support for Amazon EC2 Spot and Reserved Instances, you can also save 50-80% on the cost of the underlying instances.
Elastic
With Amazon EMR, you can provision one, hundreds, or thousands of compute instances to process data at any scale. You can easily increase or decrease the number of instances manually or with Auto Scaling, and you only pay for what you use.
Reliable
You can spend less time tuning and monitoring your cluster. Amazon EMR has tuned Hadoop for the cloud; it also monitors your cluster —retrying failed tasks and automatically replacing poorly performing instances.
Secure
Amazon EMR automatically configures Amazon EC2 firewall settings that control network access to instances, and you can launch clusters in an Amazon Virtual Private Cloud (VPC), a logically isolated network you define. For objects stored in Amazon S3, you can use Amazon S3 server-side encryption or Amazon S3 client-side encryption with EMRFS, with AWS Key Management Service or customer-managed keys. You can also easily enable other encryption options and authentication with Kerberos.
Flexible
You have complete control over your cluster. You have root access to every instance, you can easily install additional applications, and you can customize every cluster with bootstrap actions. You can also launch Amazon EMR clusters with custom Amazon Linux AMIs.
Use cases
Clickstream analysis
Amazon EMR can be used to analyze clickstream data in order to segment users, understand user preferences, and deliver more effective ads.
Real-time analytics
Consume and process real-time data from Amazon Kinesis, Apache Kafka, or other data streams with Spark Streaming on Amazon EMR. Perform streaming analytics in a fault-tolerant way and write results to Amazon S3 or HDFS.
Log analysis
Amazon EMR can be used to process logs generated by web and mobile applications. Amazon EMR helps customers turn petabytes of un-structured or semi-structured data into useful insights about their applications or users.
Extract transform load (ETL)
Amazon EMR can be used to quickly and cost-effectively perform data transformation workloads (ETL) such as - sort, aggregate, and join - on large datasets.
Predictive analytics
Apache Spark on Amazon EMR includes MLlib for scalable machine learning algorithms or you can use your own libraries. By storing datasets in-memory, Spark can provide great performance for common machine learning workloads.
Genomics
Amazon EMR can be used to process vast amounts of genomic data and other large scientific data sets quickly and efficiently. Researchers can access genomic data hosted for free on AWS.
