    This monograph discusses the Evolved Packet Core (EPC) virtualization, addressing the 4G architecture and detailing the EPC network functions. The EPC is the 4G core network, and its virtualization consists of decoupling the hardware and software used in the network nodes by implementing standard datacenters that run virtual machines to perform the network functions. Virtualization is of great value to mobile operators, providing many technical and financial advantages. Among them, a more flexible network, which will respond to market demand more quickly with low costs, lower equipment operation costs and the introduction of new services in a simpler way. EPC virtualization is critical for mobile operators, representing the first moment of the core network evolution towards 5G. However, the implementation of this network function also represents a series of challenges until operators can fully enjoy the promised benefits.
