Cloudflare AI Gateway - Pros & Cons
Pros
- ✓Core features are genuinely free on every Cloudflare account — analytics, caching, rate limiting, DLP, persistent logs
- ✓One line of code change works with existing OpenAI, Anthropic, and Google SDKs across 25+ providers
- ✓Runs on Cloudflare's edge so proxy latency overhead is single-digit milliseconds globally
Cons
- ✗Log retention is capped per plan (100k Free / 10M per gateway Paid) — not unlimited
- ✗Span-level observability and evals are thinner than Langfuse or Helicone
- ✗Dynamic Routing, Spend Limits, and BYOK are still beta with documented rough edges
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
