This handshake is successful because each party has prearranged to trust the root certificate that
signs the other party's chain.

Well-Known Certificate Authorities
----------------------------------

In these examples we've prearranged which root certificates to trust. But for regular HTTPS on the
Internet this set of trusted root certificates is usually provided by default by the host platform.

Esta simplicidad y flexibilidad permiten hacer cosas como usar bases de datos NoSQL como el sistema de almacenamiento de datos principal.

Como es muy simple, es relativamente intuitivo de aprender, aunque la documentación se vuelve algo técnica en algunos puntos.
