Sustainability In The Software Industry Statistics

Data center and networking spending still dominates IT budgets while the biggest gains are hiding in software choices, from 2 to 7% lower operating expenses via PUE improvements to up to 30% savings from license rationalization. If 67% of operators plan efficiency upgrades and the market for sustainability management software is growing 18% year over year, the real question is whether your stack is built to cut energy waste and comply fast enough.
