How can software architecture decisions impact the sustainability of a digital product?

In recent years, sustainability has become an essential factor in software development, influencing how digital products are designed and operated. Software architecture plays a crucial role in the long-term sustainability of applications, affecting everything from energy consumption to system longevity. By making thoughtful architectural decisions, developers can enhance the efficiency, scalability, and maintainability of their products, reducing their carbon footprint and extending their useful life. This raises important questions about best practices in sustainable software architecture and the balance between innovation and ecological responsibility. How do architectural choices such as microservices versus monolithic designs, or cloud-based versus on-premises infrastructure, impact the environmental and economic sustainability of a product?
