Google Colab - Pros & Cons
Pros
- ✓Completely free tier with access to NVIDIA T4 GPUs and TPUs, removing the hardware barrier for ML experimentation
- ✓Zero setup required — comes pre-loaded with TensorFlow, PyTorch, pandas, scikit-learn and most major data science libraries
- ✓Native Google Drive integration enables effortless saving, sharing, and real-time collaboration on notebooks like Google Docs
- ✓Built-in Gemini-powered AI assistance for code completion, error explanation, and natural-language code generation directly inside cells
- ✓Tight integration with the Google Cloud ecosystem (BigQuery, GCS, Vertex AI) for production-adjacent workflows
- ✓Excellent for teaching, tutorials, and reproducible research because anyone with the link can open and run the notebook
Cons
- ✗Free-tier sessions disconnect after periods of inactivity (~90 minutes idle, ~12 hours max), causing loss of in-memory state and forcing re-runs
- ✗GPU availability on the free tier is throttled and not guaranteed — heavy users frequently hit usage limits and get downgraded to CPU
- ✗No persistent filesystem on the runtime itself; data must be re-uploaded or re-mounted from Drive each session, which slows iteration
- ✗Limited RAM and disk on free tier (~12 GB RAM, ~100 GB disk) make it unsuitable for large-scale training or big-data workloads
- ✗Notebook-only workflow makes it awkward for building larger software projects, managing modules, or running long production jobs
AWS Glue - Pros & Cons
Pros
- ✓Fully serverless with no infrastructure to provision, patch, or scale manually
- ✓Deep native integration with the AWS ecosystem (S3, Redshift, Athena, Lake Formation)
- ✓Always-free Data Catalog tier lowers the barrier for metadata management
- ✓Glue 4.0 significantly improved cold start times (up to 2.7x faster) and performance
- ✓Supports both batch and streaming ETL in a single service
- ✓DataBrew enables non-technical users to participate in data preparation
- ✓Auto-scaling adjusts DPUs dynamically to match workload, reducing over-provisioning
Cons
- ✗Cold start latency for Spark jobs can reach several minutes, making it unsuitable for low-latency or interactive workloads
- ✗Debugging Spark-based jobs can be complex—error messages are often opaque and require Spark expertise
- ✗VPC networking configuration for accessing private data sources adds operational complexity
- ✗Per-DPU-hour pricing can become expensive for long-running or always-on pipelines compared to reserved EMR clusters
- ✗Limited language support—primarily PySpark and Scala, with Ray support still maturing
- ✗Job orchestration capabilities are basic compared to dedicated tools like Apache Airflow or Step Functions
- ✗Vendor lock-in to AWS; migrating Glue-dependent pipelines to another cloud requires significant rework
