This proactive approach minimizes wasted spending and optimizes resource utilization.

• Rightsizing Resources: The SAD should specify the process for evaluating and adjusting resource allocation to match current demand. This involves assessing workloads and adjusting instances, storage tiers, and other resources to avoid over-provisioning. For example, if a development workload spikes for a short period, a cloud SAD should include a strategy to automatically scale up instances during peak usage and then scale them down to a smaller size when the workload returns to a lower level.

  This ensures only the necessary resources are consumed, preventing unnecessary costs.

• Auto-Scaling Strategies: Defining clear auto-scaling policies in the SAD is critical. These policies should address the dynamic nature of cloud workloads, scaling resources up or down based on demand. This ensures optimal performance without overspending. For example, a website experiencing increased traffic during peak seasons could automatically increase its compute resources to accommodate the load, then scale back down during less busy periods.

  This avoids unnecessary costs during periods of low demand.

• Reserved Instances and Spot Instances: Utilizing reserved instances for predictable workloads and spot instances for less critical tasks are valuable strategies to reduce costs. The SAD should Artikel when and how these instance types are used, taking into account the potential risk of interrupted service with spot instances.

Cost Analysis and Modeling
