The Developer's Guide to Cloud Infrastructure, Efficiency & Sustainability

Charles Humble's 'The Developer's Guide to Cloud Infrastructure, Efficiency & Sustainability' provides practical guidance for engineers and operations teams to reduce the energy and carbon costs of cloud systems.

The book prioritizes operational improvements—such as better utilization, asset inventory, and end-of-life practices—over micro-optimizing code as the most effective route to sustainability.

It discusses energy proportionality, data-center cooling impacts, and approaches like federated learning and near-edge deployments to lower network and compute emissions.

With actionable recommendations, case studies and metrics, the book helps teams align green goals with financial savings and system reliability.

Its focus is on pragmatic steps developers and operators can take today to make cloud infrastructure more efficient and environmentally responsible.
