TECHNICAL REFERENCE
Plans and PostgreSQL
Application slots, shared resources and database beta scope.
Service resources are shared
Applications and attached managed databases share the service’s CPU, RAM and disk limits. Do not assume each application receives the whole plan’s resources independently.
The permanent free plan is not a trial. Each account can have only one non-terminated free service. Its current limits are 1 vCPU, 2 GB RAM, 10 GB disk and one application. Use the live catalog and pre-payment invoice for currency, tax and campaign eligibility.
Managed PostgreSQL
PostgreSQL can be created as a beta managed database attached to a container service. The public installation’s default quota is three managed databases per service; the limit reported for the particular service is authoritative. Creating a database does not create a separate database subscription.
Get the private endpoint and credentials from the panel. Connect the application and database through the service’s private network. Set DATABASE_URL in the actual application runtime; keep it out of the repository.
API and database are separate resources
An API application consumes one application slot. A managed database uses the separate database quota. Installing a database inside an application image is a different arrangement with different resource, storage and backup responsibilities.
