The Galactic Center is not only the region where the nearest supermassive black hole (SMBH) is located. It is also the region with the largest stellar density as well as the largest content of molecular gas in the Galaxy. In addition, the conditions of the circumnuclear medium (density, temperature, velocity, magnetic field) across the whole region vary by several orders of magnitude. Although its past evolution is still under debate, the recent Galactic Center workshop (IAU Symposium 405) in Brno, Czech Republic, managed to portray the Galactic Center as a connected ecosystem across spatial and temporal scales. In fact, it can be considered as a ``little galaxy" within the Galaxy on its own and thus serves as a nearby analogue for higher-redshift starburst systems.
