Use Light Cloud branch environments to preview a change across three services, merge it into production, and roll back a bad deploy in 13 seconds without a rebuild.
Measure cold starts on Light Cloud with curl, compare scale to zero with an always-on instance, and use real numbers to set timeouts and decide what to keep warm.
Load test a Light Cloud service with oha, watch it scale from zero to five instances, and learn why concurrency and database connection pools decide how well autoscaling works.
Allow several browser origins with CORS, rotate the secret your services share without dropping a request, and add a timeout between services, step by step on Light Cloud.
Deploy a React frontend, a Node.js API, a Python FastAPI API and PostgreSQL from one GitHub monorepo on Light Cloud, step by step, with every screen shown.
