Definition

Cloud Sustainability defines how the organization will make decisions about using cloud in ways that consider both its impact on the environment and the organization’s broader sustainability goals. Cloud Sustainability allows engineers and product personas to balance environmental considerations alongside financial costs or benefits of the cloud when architecting, optimizing, and deploying workloads in the cloud.

Many organizations have an organizational sustainability program that is looking more broadly at environmental impact than just cloud use. The amount of the environmental impact represented by cloud use will vary greatly by organization depending on all of its sources of carbon emissions. Regulation requiring more regular reporting of environmental impacts, including direct and indirect carbon emissions, is being enacted in many areas of the world. As a result, visibility of cloud usage in terms of carbon is becoming increasingly important for cost allocation, reporting, forecasting and other important IT functions.

FinOps teams should be integrating with organizational sustainability programs (via the Intersecting Disciplines Capability), incorporating sustainability information into the Understand Cloud Usage & Cost and Quantify Business Value Domains, and within this Capability should be working to identify opportunities for optimization of cloud cost and usage which support the organization’s sustainability goals. Similar to opportunities to optimize usage identified in the Workload Optimization Capability, or to optimize rates in the Rate Optimization Capability, work done in this Capability will generate potential opportunities to reduce the carbon footprint of cloud usage. Recommendations from each optimization domain can be evaluated by the FinOps team and other Personas to select the options over time that produce the best value to the organization, whether financial, environmental, or operational.

Generally speaking, Workload Optimization recommendations correlate closely with lower carbon emissions by only using what is needed, and only when it is needed (i.e. turn the lights off when not in use, use the correct size tool for the job). However, cloud sustainability efforts can run counter to cost savings in Rate Optimization efforts, where reserved discounts on certain resources might discourage optimizing them or turning them down. Some architectural or operational decisions may conflict with sustainability goals, for example the need for multiple copies of data or resources to support availability, or the use of nearby (but less energy efficient) locations for latency reasons. And some cloud services in certain locations may be less expensive, but more carbon intensive (or vice versa), leading to conflicts when deciding where to launch resources.

As with all topics in FinOps, collaboration among teams is crucial to determine the top priorities for the organization and allowing those priorities to determine how to balance tradeoffs. Cloud sustainability must be considered in the context of the needs of the business. The iron triangle balancing of cost, speed, and quality must include the cost of sustainability.

Cloud Sustainability is part of the Optimize Cloud Usage and Cost Domain, but cloud sustainability data will be used in many other Capabilities as well. For example, sustainability data may be brought in as part of Data Ingestion, allocated in the Allocation capability and will be included in Reporting & Data Analytics, will be used in Unit Economics metrics, or may be used when Benchmarking engineering teams based on their emissions cost.

Tip:
This capability references environmental impacts in terms of carbon (and equivalents), however this capability also should consider all measurable environmental impacts (including CO2e, Water usage, waste generation, etc) as data becomes available to the FinOps practitioner.

Sustainability considerations will include items such as the energy used to power and cool servers and data centers that make up the cloud, as well as the efficiency of workload architectures. In order to achieve outcomes related to Cloud Sustainability, organizations need to consider the embodied carbon which captures the full lifecycle of their cloud services, from the sourcing of materials and energy used to build the data centers, to the disposal of outdated equipment. Given the on-demand, dynamic nature of cloud use, it is relatively easier to optimize in comparison with the fixed hardware of a traditional data center. So Cloud Sustainability teams may be the first called upon to generate carbon reductions among other categories of IT spend.

Sustainability data available from each cloud provider or billing source will of course vary in its scope, granularity, and quality. FinOps teams will need to collaborate with Sustainability offices to determine the necessary granularity and how best to adjust or normalize data from the cloud providers to align with corporate mandates. Cloud Sustainability data quality concerns may continue for some time, and organizations should provide input to cloud providers or vendors about the data they require. However, the primary goal of this Capability is to use whatever data is available, even when it is incomplete, to make recommendations to the organization regarding cloud sustainability. Architectural, usage efficiency, and rate optimization decisions will continue to be made without this input if all efforts are centered on data quality rather than on using data to make directionally-correct, if imperfect, recommendations about sustainable use.

Maturity Assessment

Crawl

There may be a corporate mandate for reporting on carbon or carbon reduction, but the strategy to apply this mandate to cloud usage may not be mature
Teams have some carbon emissions data but likely poorly integrated with other data
Optimization activities are primarily centered on elasticity and turning off what is not being used
Tradeoff decisions where cost and carbon usage conflict are evaluated broadly and often on existing workloads
