The Hidden Sustainability Trade-Off: Why Committing to Cloud Resources Can Hinder Your Green Goals

Public cloud spend is something organisations everywhere are working to get under control, with FinOps teams looking at creative ways of squashing their bills.

One common approach is to maximise discounts by committing to a fixed spend and/or buying Reserved Instance and Savings Plans (or similar). Doing this can often be sensible from a purely financial perspective, gaining large discounts, but buying committed resources from cloud providers, may unintentionally be hindering your efforts to reduce your digital carbon emissions and reach your net-zero targets.

The Optimisation Paradox:

When organisations commit to substantial cloud resource investments, it can inadvertently create a mindset where cloud architects and cloud operations teams overlook optimisation opportunities. The thinking can sometimes become, "We've already spent the money on these resources, so we might as well use them to get our money's worth." This mindset can result in underutilisation, oversized instances, and inefficient resource allocation, leading to increased energy consumption and higher digital carbon emissions.

Limited Flexibility for Scaling:

Cloud commitments often come with fixed capacity or predefined usage terms, which provide cost predictability. However, they may limit the flexibility to scale resources according to actual demand. When businesses are tied to committed resources, adapting quickly to changing workload patterns or seasonal variations becomes challenging. This lack of flexibility can lead to idle or underutilised resources, contributing to unnecessary energy consumption and increased carbon emissions.

Missed Opportunities for Innovation:

By committing to specific cloud resources, organisations may unintentionally restrict their ability to explore alternative, more sustainable solutions. The cloud industry evolves rapidly, introducing new technologies, renewable energy integration, and efficiency improvements. However, commitments to specific resources can on occasion discourage organisations from exploring and adopting these innovations, hindering their ability to effectively reduce digital carbon emissions.

Inefficient Regional Deployments:

Cloud providers often incentivise committed resources in specific regions to provide cost benefits. However, this approach may lead to deployments in regions with higher carbon intensity in their energy grids. Prioritising cost savings over sustainability, organisations may unknowingly contribute to higher emissions, especially if they fail to consider the energy mix and carbon intensity of the chosen region.

Lack of Dynamic Resource Right-Sizing:

Resource right-sizing is a critical aspect of optimising digital carbon emissions. Unfortunately, committing to specific cloud resources often means committing to a fixed instance size or capacity. Without the ability to dynamically adjust resource sizes based on workload demands, organisations may struggle to align resource consumption with actual needs. This can result in energy waste and unnecessary emissions.

Conclusion:

While committed resources from cloud providers offer financial advantages, organisations must carefully consider the potential trade-offs in terms of digital carbon emissions. The mindset of "we've already spent the money, so let's use it" can hinder optimisation efforts and sustainability goals. By promoting a culture of continuous optimisation, flexible scaling, exploration of innovative solutions, and making sustainable decisions, organisations can strike a balance between cost savings and reducing their digital carbon footprint.

Embracing cloud resource optimisation practices, leveraging renewable energy options, and making informed choices regarding regional deployments are essential steps towards achieving a sustainable cloud infrastructure.

As we navigate the cloud landscape, let's remember that cost savings should not come at the expense of our planet. By critically evaluating commitments to cloud resources and prioritising optimisation and sustainability, we can shape a greener digital future.
