Abstract
In recent years, sustainability in software systems has gained significant attention, especially with the rise of cloud computing and the shift towards cloud-based architectures. This shift has intensified the need to identify sustainability in architectural discussions to take informed architectural decisions. One source to see these decisions is in online Q&A forums among practitioners' discussions. However, recognizing sustainability concepts within software practitioners' discussions remains challenging due to the lack of clear and distinct guidelines for this task. To address this issue, we introduce the notion of sustainability flags as pointers in relevant discussions, developed through thematic analysis of multiple sustainability best practices from cloud providers. This study further evaluates the effectiveness of these flags in identifying sustainability within cloud…
