We review the gauge-string dualities that arise from studying D-branes on the conifold geometry. The AdS5 × T1,1 background appears as the type ΠB dual of an SU(N) × SU(N) superconformal gauge theory with bi-fundamental fields. A warped resolved conifold is then presented as a description of holographic RG flow from this theory to the N = 4 supersym-metric gauge theory produced by giving a classical value to one of the bi-fundamentals. The warped deformed conifold is instead the dual of the cascading SU(kM) × SU((k + 1)M) gauge theory which confines in the infrared. Some features of the bound state spectrum are discussed. We end with a brief update on possible cosmological applications of these backgrounds.
