Amazon EC2 vs Amazon EMR: What are the differences?
Amazon EC2: Scalable, pay-as-you-go compute capacity in the cloud. Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers; Amazon EMR: Distribute your data and processing across a Amazon EC2 instances using Hadoop. Amazon EMR is used in a variety of applications, including log analysis, web indexing, data warehousing, machine learning, financial analysis, scientific simulation, and bioinformatics. Customers launch millions of Amazon EMR clusters every year.
Amazon EC2 can be classified as a tool in the "Cloud Hosting" category, while Amazon EMR is grouped under "Big Data as a Service".
Some of the features offered by Amazon EC2 are:
- Elastic – Amazon EC2 enables you to increase or decrease capacity within minutes, not hours or days. You can commission one, hundreds or even thousands of server instances simultaneously.
- Completely Controlled – You have complete control of your instances. You have root access to each one, and you can interact with them as you would any machine.
- Flexible – You have the choice of multiple instance types, operating systems, and software packages. Amazon EC2 allows you to select a configuration of memory, CPU, instance storage, and the boot partition size that is optimal for your choice of operating system and application.
On the other hand, Amazon EMR provides the following key features:
- Elastic- Amazon EMR enables you to quickly and easily provision as much capacity as you need and add or remove capacity at any time. Deploy multiple clusters or resize a running cluster
- Low Cost- Amazon EMR is designed to reduce the cost of processing large amounts of data. Some of the features that make it low cost include low hourly pricing, Amazon EC2 Spot integration, Amazon EC2 Reserved Instance integration, elasticity, and Amazon S3 integration.
- Flexible Data Stores- With Amazon EMR, you can leverage multiple data stores, including Amazon S3, the Hadoop Distributed File System (HDFS), and Amazon DynamoDB.
"Quick and reliable cloud servers" is the primary reason why developers consider Amazon EC2 over the competitors, whereas "On demand processing power" was stated as the key factor in picking Amazon EMR.
Airbnb, Uber Technologies, and Netflix are some of the popular companies that use Amazon EC2, whereas Amazon EMR is used by Netflix, Medium, and Yelp. Amazon EC2 has a broader approval, being mentioned in 3607 company stacks & 1618 developers stacks; compared to Amazon EMR, which is listed in 95 company stacks and 18 developer stacks.
