We focus on developing eco-friendly conditions through our core engineering strategy of designing and executing every project in the best possible way. As in one of the software development lifecycle project - integration testing - we tried to minimize energy expenses by deploying cloud services instead of conventional in-house approaches. Not only did this strategy reduce inefficient energy consumption, but it also enhanced the carbon footprint and allowed better economies of scale to the client. With the use of energy-efficient and resource-efficient measures, we show that high engineering quality and ecological responsibility are not contradictory notions.
