In the fast-evolving world of cloud computing, managing costs effectively has become a crucial aspect of maintaining a sustainable and profitable business. The “Shift left” paradigm, originally a concept in software development, emphasizes the importance of addressing potential issues early in the development process. When applied to AWS cost optimization and management, this approach ensures that cost considerations are integrated into the earliest stages of the development lifecycle.

By shifting cost management left, organizations can avoid unexpected expenses and optimize their cloud spending proactively. This blog post explores the application of the “Shift left” paradigm to AWS cost optimization, focusing on tools like Open Policy Agent (OPA) policies, Infracost, and Terracost. We will delve into how these tools can help estimate and control costs efficiently, ensuring that your AWS resources are both cost-effective and aligned with your financial goals.
