Big ideas. Useful next steps.

Free hosting can be a useful way to test a small project, but it still has product limits and operating responsibilities.

Sync keeps locations aligned; a backup supports recovery from an unwanted change or loss.

A cache stores a response so it can be reused, and a content delivery network can serve material from distributed locations.

A database decision begins with what you need to store, how it relates and which questions the application must answer.

A free plan, a trial and a credit grant are different arrangements.

An API key is a credential, not a piece of public configuration.

A prototype proves that a path can work.

Temporary cloud credits are useful for exploration, but the project needs a plan for the day the balance or eligibility ends.

A small prototype can use more cloud resources than expected when a service stays running, an API loop repeats or public traffic rises.

Serverless services manage much of the runtime infrastructure, while a virtual private server gives you a machine to configure and maintain.
