AI Gateway, Guardrails & Caching Proxy

An enterprise middleware proxy positioned between internal applications and external LLM vendors. Enforces prompt security guardrails (WAF), performs semantic prompt caching, rate-limits tenant requests, and manages API keys securely.

Prices

Estimated monthly on-demand costs for this workload architecture.

Workload Costs Comparison

Prices by provider and services that enable users to run this workload. Shape the architecture based on cloud best practices using the four Architecture Priorities below — Capacity, Performance, Reliability, and Security. Components and prices recompute as you adjust each priority (e.g. higher Security adds a WAF, KMS, and threat monitoring), and you can switch region or billing period to compare like-for-like.

How each price was matched
CloseMeets the requirement but over-provisioned — the smallest SKU this provider sells above the requested size is materially larger.ApproximateFalls short on vCPU or memory. The price is real but it buys less than the architecture asks for.No comparable SKUNothing in this provider's catalog is close enough to compare fairly. Excluded from the total — the column is not a like-for-like alternative for that line.Not offeredThe provider does not sell a product in this category at all.
Unbadged prices are exact matches. Hover any badge for the specific reason. Totals cover only the components a provider actually matched — the “N of M tracked” note under a total says how many.
