SYSADMIN VS. NETADMIN

SYSADMIN

“Anything that involved the cable, switches, routers, ping time, traceroute, etc. was not the concern of sysadmins”

NETADMIN

“As long as the light was blinking on the NIC, anything happening inside the box was not the problem of netadmin”

THE RISE OF CLOUD ADMINISTRATOR

• He / she is a…

• Sysadmins who have an understanding of how networks work, including DHCP, DNS, and IP routing, or…

• Network admins who have an appreciation for the nature of the application traffic flowing across the wires, or even…

• Software engineers who have a bit understanding about how IP subnetting works and what is ‘lsof ’ command stands for.

WHAT MAKES YOU STILL HERE

• AWS charges us almost everything, we need system architect! Save $$$

• Linux is still need to be optimized based on apps.

• As a gate keeper, clean keeper & security person.

• Overall, if you are not around, then who will be blamed if something’s goes wrong?

BRACE YOURSELF• Never think that your role is impossible to replace. Remember that

we've seen this happen before - in manufacturing!

• No more sysadmin & netadmin. They are merged into Cloud Administrator - akin to a physician: doing assessment, diagnosis, and treatment.

• Do not stop learning, try something new every time, remember that…

• Anyone who stops learning is old, whether at twenty or eighty. ~ Henry Ford
