We discuss some properties of N = 1 supersymmetric gauge theories from a supergravity perspective. In particular we show how it is possible to extract quantitative information on pure N = 1 Super Yang-Mills and SQCD from supergravity solutions describing fractional branes on orbifolds and on the conifold, both at the perturbative (scale and chiral anomaly) and non-perturbative levels (effective glueball superpotential).
