Serverless Geospatial Processing, done right.
Authoritative engineering references for designing, deploying, and operating serverless raster and vector workflows. Built for cloud GIS engineers, Python backend devs, and platform architects who care about constraint-aware architecture, cost, and observability.
What this site is
Serverless platforms reshape how spatial data is ingested, transformed, and served. Functions replace fleets, queues replace cron, and chunked I/O replaces monolithic loads — but only if the architecture respects platform limits, package size budgets, and IAM boundaries.
Each reference here distils production patterns: event-driven shapefile ingestion, raster cold-start mitigation, dead-letter routing for vector jobs, packaging GDAL into Lambda layers, and least-privilege IAM across AWS, GCP, and Azure.
The focus throughout is constraint-aware: memory, ephemeral disk, timeout, concurrency, and cost. Examples lean on Python, GDAL, and the major-cloud event primitives, and emphasise observability and deployment automation over toy demos.
