In an era where sustainability and cost efficiency are at the forefront of organizational priorities, the intersection of cloud technology and platform engineering presents a unique opportunity for businesses to align their operational goals with environmental responsibility. This session, titled "Optimizing Cloud Costs and Reducing Environmental Impact: The Role of Platform Engineering," delves into the crucial role that platform engineering plays in achieving a delicate balance between resource optimization, cost-effectiveness, and environmental sustainability within cloud environments. The session will commence by setting the stage with an overview of the current landscape of cloud sustainability. As businesses increasingly recognize the impact of their operations on the environment, the focus has shifted from merely evaluating performance and scalability in the cloud to also considering the ecological footprint of cloud services, infrastructure, and software.
