Green Programming, Green Coding and SRE: Pushing the Boundaries of Sustainable Tech

Many companies have considerably reduced execution time and incident resolution time due to the Site Reliability Engineering (SRE) implementation, thus decreasing the computing resources consumption.

From its inception, this approach has established large-scale systems of high availability and performance. Aiming to have 24/7 online services, this practice not only addresses operational efficiency but also ecological efficiency.

For instance, the emergence of containers and cloud services has facilitated resources optimization and waste reduction. In addition, the growing interest in renewable energy and energy efficiency has led companies to seek more sustainable technological solutions.

This was confirmed by Joe Beda, Kubernetes co-creator and a key player in launching several VMware solutions, at a 2023 conference:

“The SRE is a whole movement. One of its advantages is that it allows greater infrastructure efficiency management while reducing operational processes. This not only improves the user experience but also optimizes energy consumption.”

What aspects of SRE impact sustainability?

Automation

Automation seeks to diminish human errors caused by fatigue, poor attention to detail, or system incidents such as reboots.

Thanks to automation, passing out repairs, decreasing execution times, and freeing up team workload is possible so that they can focus on tasks more aligned with the company’s strategic operation.

This approach also allows for effective scaling to changes in demand, without resorting to over-provisioning of resources and thus reducing energy consumption.

Efficient scaling

Overprovisioning resources is a commonly used practice to increase more machine capacity than needed.

With SRE, resources are fine-tuned precisely and avoid waste. Once systems are scaled efficiently, utilization of current resources is maximized, which rules out the necessity for purchasing more hardware.

Such systems, which are resistant to any traffic demand, are less risky and provide users with better service.

Waste minimization

Systems designed and operated according to SRE principles are generally more stable, meaning they do not fail frequently and do not need to be replaced due to constant penalties.

This methodology’s gradual and controlled approach extends the software’s useful life and improves the hardware performance.

Cloud resource optimization

Cloud services give the possibility of enjoying a broader portfolio of tools at a better price since infrastructure costs are divided among many users.

This occurs because platforms, such as Amazon or Google, are aware that users can provide timely feedback to improve their tools and meet market standards.

Sustainability and open source

Open source allows developers to collaborate across the globe, making new features available more quickly.

Although it has not been a common choice for large companies because of security reasons, the software can be adapted or customized according to each organization’s necessities, thus reducing the tailor-made solutions acquisition that are usually more expensive.

Green programming and Green coding

While both practices contribute to a more efficient and environmentally friendly creation of information systems, many professionals tend to confuse them.

Therefore, it is important to look at them in detail and understand how they are related to SRE:

Bringing the methodologies together

The Green Programming, Green Coding, and SRE methodologies provide companies with important benefits.
As a matter of fact, by combining them within the business strategy, it is more likely to build more sustainable, reliable, and efficient systems. For example, a project may encompass Green Coding to improve code performance and use SRE tools and techniques to ensure system availability.
Since they are not mutually exclusive practices, they feed off each other and become a good way to scale the organization with a responsible vision.

Building a supportive culture

It is even crucial to go beyond the technical approach and claim the construction of a corporate culture consistent with these methodologies.
According to Benjamin Treynor Sloss, the SRE practices founder at Google:
_«Promoting an SRE culture within the company is not just about assigning a specialized team, but also about instilling reliability and shared responsibility principles throughout the organization. Every team, from development to operations, must take part in continuously improving the system reliability.” _

According to Treynor, startups and multinational companies can implement these systems regardless of their business size by involving their work teams and articulating actions with their partners and suppliers.

Therefore, implementation will only depend on the specific company context and the capabilities installed to make these methodologies integration possible.

Making the transition

If, after analyzing your company’s specific systems and processes, you have concluded that such implementation is viable, you can use it to identify areas of improvement and the efforts you will need in order to make a smooth and accurate transition.
Remember to set specific and quantifiable goals linked to your sustainability and efficiency objectives. This will help you create a defined action plan and prioritize on the greatest impact initiatives.

While it is convenient to follow up on how your business is adapting to these changes during the first few months, as you achieve the expected results, you can move forward in creating more structured processes that contribute to building a more responsible society committed to the environment.
