Evaluating the Energy Impact of Design Decisions in Web Applications
Introduction Software systems represent a significant and growing share of global energy consumption. Recent studies estimate that digital technologies account for approximately 6% of worldwide energy usage, with an annual increase of around 6.2%. This growing concern requires organizations, such as Berger-Levrault, to measure and reduce the environmental footprint of their software systems. During software development, architects explore various design solutions, including architectural styles (e.g., monolithic, microservices), programming languages (e.g.,
Automatic Evaluation of LLM and RAG: Foundations and Established Methods
In professional environments, an increasing number of companies are integrating Large Language Models (LLM) and Retrieval-Augmented Generation (RAG) solutions to automate specific tasks or support their teams. However, ensuring the accuracy and relevance of these systems’ responses is critical, particularly when handling sensitive data or high-stakes business decisions. Evaluating these models requires a rigorous approach,

You can not avoid it! — measuring the energy consumption of software systems has become essential
Measuring the consumption of software systems is becoming increasingly important for industries. Software systems accounted for 6% of the world’s energy in 2019, surpassing civil aviation for gas emissions. Governments and European administrations must consider software energy consumption when selecting products to reduce the ecological impact. Thus, it becomes essential to measure the energy consumption
