This thesis applies energy measurements to the domain of continuous integration (CI) and continuous delivery (CD) pipelines. The goal is to conduct transparent and fine-granular energy measurements of these pipelines, increasing awareness and allowing optimizations regarding their energy efficiency. CI and CD automate processes like compilation, running tests, and code analysis tools and can improve the software quality and developer experience and enable more frequent releases. Initially, the applicability of existing energy measurement approaches for these tasks is analyzed. Afterward, a generic framework consisting of a pipeline run analyzer, a resource consumption collector, and an energy calculator is proposed. A representative implementation for a state-of-the-art infrastructure is devised to demonstrate its functionality, enabling the collection, analysis, and interpretation of data from real-world examples. Finally, it is examined whether this data aligns with the theoretical considerations and can be used to optimize the pipelines. The overall goal is to contribute to the sustainability of DevOps processes and therefore counteract the disastrous consequences of unrestrained climate change. / Denna avhandling tillämpar energimätningar på området kontinuerlig integration (CI) och kontinuerlig leverans (CD). Målet är att genomföra transparenta och finkorniga energimätningar av dessa pipelines, vilket ökar medvetenheten och möjliggör optimeringar av deras energieffektivitet. CI och CD automatiserar processer som kompilering, testkörning och kodanalysverktyg och kan förbättra programvarukvaliteten och utvecklarens upplevelse samt möjliggöra tätare lanseringar. Inledningsvis analyseras tillämpligheten av befintliga metoder för energimätning för dessa uppgifter. Därefter föreslås ett generiskt ramverk som består av en analysator för pipelinekörning, en insamlare av resursförbrukning och en energikalkylator. För att demonstrera dess funktionalitet utarbetas en representativ implementering för en modern infrastruktur som möjliggör insamling, analys och tolkning av data från verkliga exempel. Slutligen undersöks om dessa uppgifter stämmer överens med de teoretiska övervägandena och kan användas för att optimera rörledningarna. Det övergripande målet är att bidra till hållbarheten i DevOpsprocesser och därmed motverka de katastrofala konsekvenserna av ohämmade klimatförändringar.

<p>The attention on environmental issues has never been as huge as today. The climate is changing and more and more evidence suggest that the cause behind climate changes is an increase of carbondioxide into the atmosphere. The increase in turn is considerd to be an act of human activity. Therefore some companies have decided to become climate neutral and implement information technology in their business in order to reduce their emissions. This thesis has three aimes: to calculate a small company´s carbondioxide emissions, study whether or not information technology could help to reduce these emissions and furthermore find out why some companies decided to become climate neutral and describe the concept climate neutral. The results show that if information technology is used properly and effectively there are great potential to reduce the emissions, especially emissions from transportation sector. Now that the environment issues has become number one in the news and in the political agenda many companies try to cut their emissions, which is why some companies decided to take one step further and become climate neutral. Most of the companies see this action as a necessity in order to survive in a high competitive market. By doing so, they get more PR and more credit from both their investers and custumers. That is also why GreenIT´s carbondioxide emissions where calculated here. GreenIT have intentions in becoming climate neutral and in order to becoming one they have to reduce their remaining emissions by investing in projects in developing countries. As GreenIT is a small company they don´t have large emissions to reduce. This action will not cost them much but will probably give them an advantage in the market and credit from other investors and customers.</p>
