The increasing adoption of cloud computing and the rise in popularity of resource-intensive Big Data and Machine Learning workloads has led to a steady growth in data center deployments worldwide, raising fears of excessive energy consumption and greenhouse gas emissions. Given that the benefits of existing hardware and virtualization technologies have largely plateaued, new, disruptive approaches are needed to address this "second wave" of data center energy concerns.

This project proposes data center management techniques that will enable "sustainable-by-design" data centers. The key component of our work will be an end-to-end secure sustainability accounting framework that estimates the total sustainability footprint of a job across all layers of the data center stack that the job traverses. Our framework will take into account the cleanliness of the energy source, its greenhouse gas emissions, and the embedded energy of IT equipment, thus holistically capturing sustainability costs. To realize end-to-end benefits, we will develop new programming models and tools that allow users to participate in sustainability efforts by securely exposing job-specific information and control knobs to data center operators. At runtime, the job sustainability cost estimates and user-provided information will guide data center management components, such as the scheduler and resource allocator, to make data-center–wide sustainable choices.
