5 AWS Services Every Data Scientist Should Use

Amazon Web Services (AWS) offers a vast range of cloud solutions, from core services like Elastic Compute Cloud (EC2) and Simple Storage Service (S3) to an array of Platform-as-a-Service (PaaS) tools that cater to nearly every area of modern computing.

Specifically, AWS provides a comprehensive big data ecosystem supporting the entire data processing pipeline—from ingestion and pre-processing to ETL, querying, analysis, and visualization. This enables organizations to manage big data effortlessly, without the need to set up complex infrastructure or deploy frameworks like Spark or Hadoop.

In this guide, I’ll cover five essential AWS services that address key stages of the modern data science workflow.

1. Amazon EMR

Amazon EMR simplifies the process of running big data frameworks like Hadoop and Spark. It supports big data processing on AWS resources, such as EC2 instances and cost-effective spot instances, and facilitates data migration between AWS databases (e.g., DynamoDB) and storage solutions (e.g., S3).

• Storage: Amazon EMR supports the Hadoop Distributed File System (HDFS) and EMR File System (EMRFS). HDFS offers ephemeral storage across cluster instances for intermediate results, while EMRFS provides direct access to data stored in Amazon S3.

• Data Processing Frameworks: Amazon EMR supports Hadoop MapReduce for distributed computing and Apache Spark for high-performance data processing with in-memory caching.

Amazon EMR enables you to launch clusters, develop distributed processing applications, submit tasks, and view results without the hassle of hardware setup or big data framework configuration.

2. AWS Glue

AWS Glue is a fully managed, cost-effective ETL service that allows you to classify, clean, enrich, and transfer data. Serverless and flexible, it includes a Data Catalog, a scheduler, and an ETL engine that generates Scala or Python code.

AWS Glue’s dynamic frames handle semi-structured data, offering schema flexibility and advanced transformations compatible with Spark dataframes. The console allows you to discover data sources, transform data, and monitor ETL tasks, which can be automated with triggers or run on-demand.

3. Amazon SageMaker

Amazon SageMaker is a fully managed MLOps platform for building, training, and deploying machine learning models. It provides Jupyter notebook instances to access data sources easily and offers built-in ML algorithms optimized for distributed environments.

With SageMaker, you can create training jobs specifying S3 buckets for data storage, output locations, compute resources, and training code paths, and then tune models using SageMaker Debugger.

4. Amazon Kinesis Video Streams

As video content grows in importance, Amazon Kinesis Video Streams allows for live video streaming to AWS, real-time processing, and batch-oriented analytics. You can capture and process large volumes of video and audio data from various devices with low latency, and integrate video APIs for additional processing.

• Components: Producers (data sources), Kinesis video streams (data transfer), and consumers (data recipients such as EC2 applications) all work together to provide real-time or on-demand data access.

5. Amazon QuickSight

Amazon QuickSight is a fully managed BI tool that unifies data from multiple sources into a single dashboard. It features strong security, built-in redundancy, and global availability, with SPICE (Super-fast Parallel, In-memory Calculation Engine) memory for efficient data handling.

QuickSight allows you to prepare data, create visualizations, and publish dashboards, which are accessible from any device with network access.
