Sustainability Implications Demand Comprehensive Approaches Renewable progress is great, and necessary, but INSUFFICIENT

natural resources carbon footprint demand growth

clouds drive demand https://greensoftware.foundation/ inefficient toolchains software footprint

Sustainability, ESG, …, OSPO Pursuing sustainable software can be a partnership between a corporate sustainability program and an OSPO => like other cross-silo corporate projects Perhaps controversial to say that software sustainability belongs in an OSPO – cross-department, company-wide – and we should have that debate The role of OSPOs and Sofware Sustainability is a topic for a future talk! Happy to entertain questions at the end

Open Is Necessary, But Not Sufficient Per Se design, engineering and product expertise, rigorous commitment to component quality [hardware] design, engineering and product expertise, rigorous commitment to component quality from capacitors to CAP theorem to cognitive load wide dynamic range of skills must be applied & appreciated ORCHESTRATING AN OPEN HARDWARE + OPEN SOFTWARE STACK [software] requires baseline partnership across hardware & software devops – collaboration from designers & developers to operations automation, analytics, and machine learning for all the things I8

OPEN HARDWARE, OPEN SPECIFICATIONS • instead of every company making their own unique specifications • we work together on common elements to think about • specifications that maximize cooling and reduce heat • high density servers for maximum computation per floor tile • form factors that can use any space in any location – under desks, in closets of various sizes, outdoors – to drive edge computing • design for use of off-the-shelf components that are already efficient in mass production • re-use, re-purpose, revamp the Hardware Supply Chain

These are not pie in the sky ideas – they are already actively implemented under the aegis of the Open Compute Project and the Linux Foundation

CASE STUDY – AMSTERDAM …FOR GREENHOUSES

CASE STUDY – AMSTERDAM Green data centers require innovative partners “WE’RE SAVING 20 – 30% ON AIR-CONDITIONING COSTS BY GOING WITH OUR DECENTRALIZED APPROACH. CONSTRUCTION TIMES ARE ALSO SIGNIFICANTLY REDUCED. THOSE BENEFITS ALLOW US TO BE SUSTAINABLE AND ECONOMICALLY COMPETITIVE AT THE SAME TIME.” “WE CHOSE ITRENEW FOR THEIR SUSTAINABILITY CREDENTIALS, SUPERIOR TECHNOLOGY, ‘OPEN COMPUTE’ FLEXIBILITY, AND THE SKILL OF THEIR ENGINEERING TEAM TO DELIVER ON OUR REQUIREMENTS AT SCALE—ALL OF WHICH HAVE ENABLED US TO ACCELERATE OUR DEVELOPMENT.” JEROEN BURKS, CEO BLOCKHEATING

THE CIRCULAR IT HARDWARE INDUSTRY IN PRACTICE START HERE Design and procure hardware that enables circularity HYPERSCALE DATA CENTERS COST AVOIDANCE INTERNAL RE-USE 1 2 RACK-SCALE SOLUTIONS 3 EDGE SOLUTIONS 4 RE-CERTIFIED COMPONENTS 5 RESPONSIBLE RECYCLING LIFETIME VALUE MULTIPLIER IN AGGREGATE TARGET MARKETS • CSP/COLO • GAMING • INDUSTRIAL • IOT • RETAIL • ENERGY • TELCO • ENTERPRISE VALUE RECOVERY

CIRCULAR ECONOMY – SOFTWARE The circular economy enables - Near metal open source toolchains like coreboot, linuxboot, u-root to keep older machines in the market longer based on community support - Open hardware can be re-designed for new uses like modular datacenter, edge computing at near neutral carbon cost at cheaper TCO than new hardware - Open Hardware doesn’t just mean servers, but also switches - Augments software projects like LF’s OpenSwitch [https://www.openswitch.net/] - Any software project that supports using off the shelf parts to build open infrastructure can leverage the supply chain provided by the circular economy

SUMMARY YES – improve the software toolchain to improve open source projects so that the hardware is used at high utilization and high efficiency through efforts like the Green Software Foundation YES - leverage the supply chain of the circular economy and benefit from open hardware and near neutral carbon costs of recertified equipment YES - adapt your infrastructure to use open hardware that runs open source infrastructure hardware – e.g. SONiC, openswitch, k8s, OpenBMC YES – Find ways to re-use the output of your on-prem cloud or datacenter

Sustainability all the way down – means we don’t stop at just software but explore everything below it as well If you have a sustainability program at your company – leverage the OSPO to navigate the cross-silo collaboration required to support open sustainable infrastructure as well as open code
