Factor cost into architectural decisions

Factoring cost into architectural decisions is crucial for maximizing resource utilization and enhancing performance efficiency. By understanding cost implications, organizations can select the right mix of resources and techniques to avoid wasteful practices and improve overall operational efficiency.

Best Practices

Implement Cost-Aware Resource Selection

• Evaluate and compare the cost-effectiveness of different resource types, such as reserved instances, spot instances, or on-demand instances, based on your workload’s usage patterns.
• Leverage AWS Cost Explorer to analyze cost trends and resource utilization over time, which helps in making informed decisions regarding resource allocation.
• Utilize AWS Pricing Calculator to estimate the costs of various architectural designs and configurations, ensuring financial feasibility before deployment.
• Incorporate cost considerations into initial architectural discussions, setting clear cost-saving goals alongside performance objectives to guide decision-making.
• Regularly review and optimize your resource usage, eliminating underutilized or unnecessary services to reduce costs while maintaining performance standards.
• Establish a culture of cost awareness among your technical teams, encouraging them to consider costs in their design and operational decisions, which leads to efficient resource utilization.

Questions to ask your team

• Have you analyzed the cost implications of the chosen architecture patterns for your workload?
• Do you regularly review your resource utilization to identify potential cost savings?
• Are you using cost management tools to monitor and optimize your resource allocation?
• How do you account for performance requirements when considering cost-effective solutions?
• Is there a process in place for adjusting resources based on performance and cost metrics?
