Description: The ‘zero-cost architecture’ is an architectural approach aimed at minimizing costs to the point where they are insignificant. This concept focuses on optimizing cloud resources, seeking not only to reduce expenses but also to maximize operational efficiency. In an environment where companies increasingly rely on cloud services, zero-cost architecture becomes a key strategy to ensure that spending on infrastructure and services is sustainable and aligned with business objectives. The main features of this approach include process automation, the use of pay-as-you-go services, and the implementation of FinOps practices, which allow for tighter control over costs. Additionally, it fosters innovation by freeing up resources that can be reinvested in the development of new solutions and improvements. In a world where competitiveness is fierce, adopting a zero-cost architecture is not only an economic advantage but also a way to ensure the agility and adaptability of organizations in the face of a constantly changing market.
