This approach leverages Chuck's already working scripts while adding: - JSON caching with 24-hour TTL in ~/.cache/kdevops/aws/ - Parallel fetching of instance data (10 concurrent workers) - Parallel file writing (20 concurrent workers) - Proper data structure handling for families list Performance improvements: - First run: ~21 seconds to fetch all data from AWS - Cached runs: ~0.04 seconds (525x faster) - Generates 75 Kconfig files for 72 instance families The script properly uses Chuck's existing AWS API implementations rather than reimplementing them, maintaining code reuse and consistency.
