Large Nitric stacks produce a resource-index JSON that exceeds the 4,096-character limit of the SSM Standard tier, causing deployment failures. Detect the JSON size at deploy time and automatically upgrade to the Advanced tier (8,192-char limit) when needed. Applies to both the Pulumi provider (deploy/resources.go) and the Terraform CDKTF provider (deploytf/.nitric/modules/parameter/ and deploytf/resources.go). Small stacks are unaffected and continue to use the Standard tier at no additional cost.

Description
When a Nitric stack grows large enough, the resource-index JSON written to AWS SSM Parameter Store exceeds the Standard tier's 4,096-character limit, causing deployment failures with a
ParameterValueTooLongor tier-related validation error.This change detects the JSON size at deploy time and automatically selects the appropriate SSM tier:
Standard(default, no cost impact)Applies to both the Pulumi provider (
cloud/aws/deploy/resources.go) and the Terraform CDKTF provider (cloud/aws/deploytf/). Small stacks are unaffected.Type of change
Testing
This is a simple conditional change —
go buildandgo vetpass on the affected packages. No unit tests added as the deployment provider packages (deploy/,deploytf/) have no existing test coverage.
