Black hole information paradox is a well known problem. Recent progress hints towards a new understanding of the late time black hole interior as part of the Hawking radiation, which they called island. In particular the island formula for the radiation entropy gives Page curve and therefore maintains unitarity. In this talk I will discuss how to derive Page curve from holography. We provide an explicit construction of gravity system attached with bath by gluing Randall-Sundrum reduction and Maldacena duality, and derive Page curve from holography. We also provide a holographic construction for cosmology based on partial reduction. Our approach hints towards an origin of the holographic nature of black holes as well as our universe.
