Sustainable practices in DevSecOps: Reducing your digital footprint

As the tech industry continues to expand, so does its environmental impact. From data centres consuming massive amounts of energy to the electronic waste generated by obsolete hardware, the carbon footprint of our digital lives is significant. However, the principles of DevSecOps — integrating security and operations into development processes — can be harnessed not just for efficiency and security but also for sustainability.

This article explores how DevSecOps can contribute to environmental sustainability, practical steps for implementing green practices in daily work, and case studies of companies that are leading the way in sustainable DevSecOps.

How DevSecOps can contribute to environmental sustainability

  • Optimising resource usage
    • Infrastructure as Code (IaC): By using IaC, teams can automate the provisioning of resources, ensuring they only use what they need. This reduces the likelihood of over-provisioning, which often leads to unnecessary energy consumption.
    • Containerisation: Containers are more efficient than traditional virtual machines because they share the host system’s kernel. This means they require less overhead, leading to reduced energy usage.
  • Efficient code practices
    • Code optimisation: Writing efficient code can reduce the processing power required to run applications. This not only speeds up performance but also decreases energy consumption.
    • Automated testing: Continuous Integration/Continuous Deployment (CI/CD) pipelines that include automated testing can ensure that only code meeting certain efficiency standards gets deployed, preventing resource wastage.
  • Data management
    • Data minimisation: Reducing the amount of data stored and processed lowers the energy required for storage and computation. Implementing data lifecycle management helps in deleting unnecessary data.
    • Energy-efficient algorithms: Choosing algorithms that require less computational power can significantly cut down energy usage, especially in data-intensive applications.

Implementing green practices in your daily work

  • Adopt cloud-native solutions
    • Serverless architectures: Use serverless computing to automatically scale resources based on demand. This ensures that you only use the resources needed at any given time.
    • Green cloud providers: Choose cloud providers that prioritise renewable energy sources and have strong sustainability commitments. Providers like Google Cloud and AWS have initiatives to reduce their carbon footprint.
  • Optimise CI/CD pipelines
    • Pipeline efficiency: Streamline CI/CD pipelines to minimise the number of redundant processes and tests, reducing the overall computational load.
    • Scheduled builds: Instead of running builds continuously, schedule them during off-peak hours when energy consumption is lower or batch them to reduce frequency.

  • Energy-efficient development environments
    • Virtualisation: Use lightweight virtual environments instead of resource-heavy local machines for development and testing.
    • Remote work policies: Encourage remote work to reduce commuting emissions and utilise energy-efficient home office setups.

Case studies of companies leading the way in sustainable DevSecOps

  • Google Cloud
    • Carbon-neutral data centres: Google Cloud has achieved carbon neutrality and aims to run on 24/7 carbon-free energy by 2030. Their data centres use advanced cooling techniques and AI-driven optimisation to minimise energy use.
    • Sustainable software development: Google promotes practices such as optimising code for energy efficiency and reducing the computational cost of applications.
  • Microsoft Azure
    • AI for Earth: Microsoft’s AI for Earth program supports projects that use AI to solve global environmental challenges. Azure also operates with a commitment to be carbon-negative by 2030.
    • Green software engineering: Microsoft encourages the use of principles from the Green Software Engineering community, which focuses on reducing carbon emissions through software design and deployment.
  • Salesforce
    • Sustainable development goals: Salesforce has integrated sustainability into its core values, committing to net-zero emissions across its value chain and 100% renewable energy for its global operations.
    • Eco-friendly DevOps practices: They utilise efficient data centre operations, promote the use of energy-efficient coding practices, and engage in regular sustainability audits to ensure ongoing improvements.

Final thoughts

Incorporating sustainability into DevSecOps practices is not just beneficial for the environment but also for business efficiency and innovation. By optimising resource usage, adopting green development practices, and learning from companies that are leading in sustainability, DevSecOps teams can significantly reduce their digital footprint.

As we move towards a more eco-conscious future, the integration of sustainability into every aspect of technology, including DevSecOps, will be crucial in driving long-term environmental change.

By adopting these practices, not only do we contribute to a healthier planet, but we also pave the way for a more sustainable and efficient technological landscape.
