Massive stars (> 8 Msun) have a significant impact, through their energetics, on the evolution of galaxies and the universe in general. The energetics of massive stars can also affect star formation positively and negatively. However, despite their importance, the understanding of the birth and feedback processes involving massive stars is still under debate. In recent years, space-based infrared observations have revealed many massive star-forming regions which contain infrared dark clouds, mid-infrared shells or bubbles, 6.7 GHz methanol maser emission, HII regions, and young star clusters together. It is indeed obvious that such sites host numerous complex physical processes of star formation. At the same time, these sites are extremely promising to probe important observational evidences concerning the formation of massive stars and their feedback. I will present the results of an analysis of promising massive star-forming regions using a multi-scale and multi-wavelength approach.
