Climate change concerns have already impacted data center strategies.\n\nOver the past 18 months, industries have had to accelerate their digital transformation journeys to remain competitive. From retail to healthcare and even financial services; no sector has escaped the reality that digitisation is a necessity for survival. Meanwhile, the international calls for urgent action on climate change have made shrinking carbon footprints an additional business imperative. As a result, executives are under tremendous pressure to adapt and transform existing processes to drive customer engagement, employee productivity, and business resilience \u2013 all while maximising the sustainability of their IT.\n\nTake Singapore as an example, where climate change concerns have already impacted data center strategies. Experts estimate that data centers consume approximately 7% of the nation\u2019s total energy, prompting the government to put a \u2018temporary pause\u2019 on new data centers in\u00a02021. It is estimated that data centers are likely to go from using 1% of global energy in\u00a02021\u00a0to increase 15-fold by 2030, equivalent to 8% of projected global demand, making sustainability an urgent business for organizations\u00a0worldwide.\n\nSo, how should organisations approach minimising their IT carbon footprint? The answer is to take a holistic view of the total lifecycle of the solutions that make up their digital transformation projects. This means overlaying a sustainability lens on all they do \u2013 from infrastructure, through monitoring, and to decommissioning.\n\nTarget underutilisation\n\nUnderutilisation is not only a business problem but also an environmental one. We know that for years businesses have built excess capacity into their data center and cloud resources to ensure capacity needs are met at any moment. This results in inflated costs and unwarranted energy consumption. While underutilisation estimates vary, according to Computer Economics, nearly 80% of production UNIX servers are utilised at less than 20% capacity, and over 90% of Windows servers are used at less than 20% capacity, while still drawing 30% to 60% of their maximum\u00a0power.\n\nThus, when selecting infrastructure providers \u2013 whether for on-premises or public cloud \u2013 organisations should choose a provider focused on reducing power usage and carbon emissions. Furthermore, using software-defined infrastructure (SDI) and virtualisation techniques helps cut carbon footprint. SDI has emerged as an effective approach to address the extensive demands on maximising the value potential of infrastructure deployments. It is now being built into IT consumption models providing capacity-on-demand platforms.\n\nEstablishing development and deployment processes\n\nBusinesses should also examine their software development and deployment processes for sustainability gains. Selecting the proper framework and algorithm can reduce energy consumption. For example, tools like AWS Codeguru help profile applications and frameworks and provide automatic recommendations on potential improvements. These could include reducing central processing unit (CPU) utilisation and application latency to lower infrastructure costs and enable more energy-efficient applications.\n\nOn the deployment front, using microservices-based frameworks can help with overall infrastructure utilisation. Running applications on serverless technologies can also be highly energy-efficient, as the applications only use the compute infrastructure when they are running.\n\nAnother critical decision for organisations is the runtime frameworks for applications. For artificial intelligence (AI) and machine learning (ML) apps, utilising graphics processing units (GPUs) can help reduce the overall carbon footprint. Even though the observed power for GPU is high, applications finish faster, resulting in the total energy consumption being notably less than CPU versions. Additionally, research has shown that GPU achieves an energy-frame reduction ratio of 1.1\u20133.2\u00d7\u00a0compared to the others for\u00a0simple kernels, making it a more sustainable alternative.\n\nMonitor and manage applications with AIOps\n\nTo avoid excess energy usage, reactions to IT events should be immediate to counter disaster. Traditional approaches to managing IT applications can be heavily manual and result in inefficient energy usage. New techniques like AIOps can enhance the efficiency of managing IT operations and reduce organisations\u2019 carbon footprint. AIOps cuts through the noise and identifies, troubleshoots, and resolves common issues within application operations. It brings together data from diverse sources and performs a real-time analysis right at the source. Furthermore, it understands and analyses historical and current data, linking anomalies and observed patterns to relevant events via machine learning. It also initiates appropriate automation-driven action, which can yield uninterrupted and energy-efficient IT operations.\n\nDecommissioning applications and infrastructure\n\nDecommissioning applications is one of the most challenging exercises because of the stored data within the apps. Having the right archival strategy is crucial and will allow IT teams to simplify application decommissioning.\n\nAnother essential aspect to consider is infrastructure decommissioning. When looking for a technology partner, make sure the partner has decommissioning capabilities as part of their own circular economy strategy. For example, HPE Financial Services (HPEFS) Asset Upcycling Service helps customers maximise end-of-use assets. Organizations can convert their replacement systems into the previously mentioned consumption model approach, in turn achieving a two-for-one sustainability outcome. An example of this is DAA, the global airports group, which converted to as-a-service using the HPE GreenLake platform, while upcycling obsolete legacy assets. DAA benefitted from the residual market value of the old IT while reducing both e-waste and carbon emission\u00a0impacts.\n\nThe bottom line\n\nWith every industry charging ahead with digital transformation strategies, business leaders and environmentalists alike are concerned with the negative impacts of surging energy consumption. As industries everywhere mobilise to embrace the digital economy, smart companies will seize this moment as an opportunity to integrate sustainability into their digital transformation strategies \u2013 to mitigate both the societal and financial costs of unchecked energy demands.\n\n____________________________________\n\nAbout Vinod Bijlani\n\nVinod Bijlani leads the AI and IoT Practice for HPE.
