Green ITOM: Reducing the carbon footprint of IT operations
ManageEngine ITOM
A unified ITOM solution to manage networks, servers, and applications. Trusted by 1 million IT admins for over 15 years.
As climate change intensifies the IT sector must act decisively. The role of IT operations management (ITOM) in reducing carbon emissions has become increasingly crucial.
This approach not only supports corporate sustainability goals but also drives cost savings and operational efficiency.
In this edition of the ITOM Insider newsletter, we will explore:
IT operations have a significant environmental impact due to the substantial energy consumption of data centers, network equipment, and end-user devices. According to the?International Energy Agency (IEA), data centers account for approximately 1% - 1.5% of global electricity demand. With the rapid growth of digital transformation initiatives, this figure is expected to rise, making it imperative for organizations to adopt green ITOM practices.
1. Optimize data center efficiency:?
???- Virtualization:?Consolidating workloads onto fewer servers reduces the number of physical machines needed, cutting energy consumption and cooling requirements. For instance, VMware's virtualization solutions can reduce energy use by up to 80%.
???-?Efficient cooling: Advanced cooling technologies, such as liquid and free cooling, can significantly cut the energy needed to maintain optimal temperatures in data centers. Transitioning to liquid cooling can reduce power consumption by more than 27%.
???-??Energy-efficient hardware: Investing in energy-efficient servers, storage, and networking equipment can lead to substantial energy savings. For instance, Energy Star certified servers and storage devices can lead to energy savings of 30-40%.
?2. Embracing cloud computing:?
Cloud service providers often have more efficient data centers than on-premises facilities. AWS, for example, aims to power its operations with 100% renewable energy by 2025.??Migrating to such providers can lower carbon emissions due to shared infrastructure and economies of scale.
???- Serverless architectures: Research suggests servers consume 40% of the total energy consumption in data centers. Utilizing serverless computing models can optimize resource usage, as resources are only consumed when functions are executed.

?3.?Implementing AI and automation:?
???- AI for predictive maintenance: AI can predict equipment failures, allowing for proactive maintenance and reduced downtime, enhancing overall energy efficiency.
???- Automated workload management: AI-driven tools can optimize workload distribution across servers, ensuring efficient resource use and minimized energy consumption.

?4. Promoting sustainable software development:?
???- Green coding practices: Encouraging developers to write energy-efficient code and optimize algorithms can reduce CPU usage and energy consumption. Energy-efficient coding practices can reduce energy consumption by up to 50%.
???- CI/CD optimization: Streamlining continuous integration/continuous deployment (CI/CD) pipelines can reduce the frequency of builds and deployments, conserving energy and also enable faster time to market.
?5. Enhancing network efficiency:?
???- Software-defined networking (SDN): SDN can significantly optimize network traffic, reducing the energy consumption of network devices by up to 50%.
???- Energy-efficient ethernet (EEE): Implementing EEE standards can lower the power consumption of network devices during periods of low data activity.
Accurate measurement and transparent reporting of the carbon footprint are foundational to green ITOM. The Greenhouse Gas (GHG) Protocol provides a robust framework for quantifying and reporting emissions. Integrating energy management systems (EMS) with advanced analytics offers real-time insights into energy consumption patterns, identifying inefficiencies and areas for improvement.
Investing in green ITOM is an investment in the future—one that aligns technological advancement with environmental stewardship.
