When should I use Amazon EC2 instead of Amazon Redshift?

Running compute workloads on configurable virtual machines with specific CPU, GPU, or memory needs. Hosting custom data processing software not supported by managed AWS services. Long-running data engineering jobs where Lambda timeouts or ECS overhead are a constraint

When should I use Amazon Redshift instead of Amazon EC2?

Cloud data warehouse for petabyte-scale analytical SQL queries in the AWS ecosystem. BI and reporting workloads that need fast columnar storage and MPP query execution on large tables. Teams already standardized on AWS who need a managed data warehouse without infrastructure work

What are the main weaknesses of Amazon EC2?

Requires manual management of OS patches, scaling, availability, and network configuration. More expensive than serverless alternatives for bursty or short-lived workloads. Operational overhead compared to managed services like ECS, EKS, Lambda, or EMR Serverless

What are the main weaknesses of Amazon Redshift?

Expensive at scale — reserved or on-demand capacity costs grow quickly with data and query volume. COPY-based bulk loading is the fast ingest path; single-row inserts are very slow. Competes poorly with Snowflake and BigQuery on serverless scaling, ease of use, and feature velocity

How Python Data Engineers Use These Tools

Amazon EC2

Python data engineers use EC2 to run compute-intensive batch processing jobs that outgrow serverless limits. Spot instances are commonly used for large PySpark or pandas processing jobs — engineers provision fleets via boto3, run the Python job, write results to S3, and terminate the instance automatically to minimize cost.

Amazon Redshift

Python data engineers load transformed data into Redshift using the COPY command via boto3 — staging data in S3 first then issuing a COPY SQL statement for fast bulk load. Libraries like `redshift_connector` and `sqlalchemy-redshift` enable DataFrame-to-table writes and SQL queries directly from Python notebooks and Airflow tasks.
