There is a blending of the system administrator and network administrator roles as a result of emergence of cloud computing and software defined infrastructures. Historically, the demarcation of the two, happened at the RJ-45 socket on the NIC. Anything that involved the cable, switches, routers etc. was not the concern of the sysadmins. Likewise, if the light was blinking on the NIC, anything happening inside the box was not the problem of network admins. Now, sysadmins, particularly application administrators, must now be cognizant of network technologies and operations, network admins who want to keep networks in top shape must now have an awareness of what application traffic is flowing across the network and how to design and implement networks to support those needs. Thus the roles are merging and in the near future, they both can be together known as "cloud administrators". Read more at: http:
