The path to sustainable technology involves complex technical and organizational decisions that aren't immediately obvious from industry best practices. This talk shares seven key lessons drawn from implementing Green IT at scale in a scaleup environment and in a public bank institution. I'll examine architectural impacts through a microservices to modular monolith migration and explore how FinOps practices align with energy efficiency.
Using actual implementation metrics and case studies, I'll discuss practical approaches to measurement challenges, effective change management strategies, and the critical role of full-stack optimization. I'll also address the emerging challenges of AI energy consumption in production and evaluate current approaches being tested in the industry. Tech leaders will leave with actionable frameworks for evaluating Green IT initiatives and implementing effective measurements.
