With the advent of public cloud and its widespread adoption, the IT consumption model has moved from CapEx to OpEx model as more and more companies are operating in public cloud. The new IT OpEx model from cloud cost perspective brings peculiar concepts such as on-demand usage, pay-as-you-go pricing models, commitment based discounts etc. To run workloads in the Cloud OpEx model, there are certain best practices which can be followed to utilise the cloud resources in an efficient and effective manner from both Cost cum Finance and sustainability perspective.
The Cost cum Finance perspective of Cloud OpEx model is termed as FinOps which arches over activities such as creating guardrails, utilising the cost effective models and refining architecture to get most out the dollars spent. AWS has created a Well Architected Pillar called Cost Optimisation Pillar which encapsulates the best practices for the same. The term coined for the Sustainability perspective of Cloud OpEx model is GreenOps covering the best practices to reduce the carbon footprint of running workloads which falls under Scope-3 for the cloud users. AWS has recently released the sixth Well Architected pillar, the sustainability pillar, to make users aware of the practice.
We are making the case that besides leveraging the economies of scale from a financial point of view, now more than ever we should also consider what running workloads on the cloud can bring to sustainable business goals. ICT forms about 3% of the total global greenhouse emissions. Any step taken to reduce ICT carbon emissions is paramount. This is where the public cloud is becoming a game changer with emphasis on green, renewable energy usage and driving efficiency in their hyper-scale data centres. Through this awareness, a new practice is born: GreenOps. It encapsulates all the efforts done to reduce the carbon footprint of the resources running on the cloud by the cloud user focusing on efficiency.
In this talk, Mudit Gupta will explain how the union of FinOps and GreenOps best practices have resulted in a new domain altogether: Cloud Sustainability. They give examples of how cloud relates to the various pillars of business sustainability, cost optimisation, demonstrate how to visualise and act on your cloud carbon footprint, and provide practical steps to further increase your efficiency, thus reducing carbon footprint, and AWS costs.
