Is Heroku's Shield-S the best deal?

Before you switch

• Verify that Shield-S dedicated compute and compliance certifications are actually required for your workload; if not, Heroku Standard or Performance dynos may offer better value
• Confirm Postgres tier requirements: Essential has a 99.5% SLA and no HA, which may be a reliability cliff for production use
• Test overage scenarios for Postgres row/connection limits and Redis memory to estimate true monthly cost under realistic load
• If you need HA Postgres, contact Heroku sales for Advanced tier pricing before committing, as it is not publicly listed
• Evaluate whether Private Spaces network isolation premium (2-3x markup) is justified by your security model, or if common runtime suffices
