When should I use Amazon S3 instead of Google Compute Engine?

Storing any volume of files as objects in a durable, globally available data lake foundation. Staging area for ETL pipelines — landing zone for raw data before transformation. Serving Parquet, ORC, and Avro files to Athena, Redshift Spectrum, and Spark for analytics

When should I use Google Compute Engine instead of Amazon S3?

Running VMs on Google Cloud with per-second billing, custom machine types, and Spot instance support. Compute workloads requiring specific GPU or TPU hardware available only on GCP. Custom data processing software that cannot run on managed GCP services like Dataflow or Dataproc

What are the main weaknesses of Amazon S3?

Not a database — no query capability without a separate engine like Athena or Redshift Spectrum. Costs can escalate with high API call volumes, especially LIST operations and small file reads. Eventual consistency for overwrites was a historical footgun; now fully consistent but worth knowing

What are the main weaknesses of Google Compute Engine?

Requires manual OS and infrastructure management — patching, scaling, and availability are your responsibility. More expensive than serverless Cloud Run or Cloud Functions for bursty or short-duration jobs. GCP-specific; skills and tooling do not transfer to AWS or Azure compute environments

How Python Data Engineers Use These Tools

Amazon S3

S3 is the standard data lake storage layer for Python data pipelines on AWS. Engineers use boto3 to read Parquet files into pandas, write pipeline outputs back to S3 with partitioned prefixes (year/month/day), and trigger downstream jobs via S3 event notifications. Tools like Athena, Glue, and EMR read directly from S3 without any data movement.

Google Compute Engine

Python data engineers provision and manage Google Compute Engine VMs using the google-cloud-compute Python library or Terraform. GCE is used to run self-hosted data engineering tools like Apache Airflow, Spark clusters, and PostgreSQL databases on managed VMs. Engineers use Preemptible VMs for cost-efficient batch processing jobs and custom machine types to right-size compute for memory-intensive transformation workloads.
