cost-aware-architecture

Cost-aware architecture is an approach to designing SaaS systems that balances performance and reliability with cloud spend. It identifies top cost drivers like compute, storage, and egress to prevent runaway cloud costs while preserving system reliability.

To track cloud spend by customer, you need a cost-tagging strategy combined with tenant-level cost attribution. This allows you to allocate compute, storage, and egress costs accurately to specific features or customers across your SaaS infrastructure.

You can compare cloud costs across providers and configurations by using architecture decision templates for caching, data placement, and resource sizing. These templates quantify cost outcomes and tradeoffs for compute, storage, and data path alternatives during architecture reviews.

Yes, architectural decision templates can establish budget guardrails by evaluating cost tradeoffs during SaaS design and budgeting cycles. These templates guide caching, data placement, and resource sizing decisions to keep spend within defined limits.

The best way to start a cost-aware architecture review is to identify your top cloud cost drivers, evaluate your current tagging strategy for tenant-level attribution, and define decision templates for caching, data paths, and resource sizing with explicit cost outcomes.
