This is a debate I am having right now. Should I go the sysadmin route (hadoop clusters, etc), become a data scientist, or choose to get into cybersecurity. I have been leaning against choosing the web development career path
Trite, but accurate. This role is currently in high demand, with correspondingly good salaries. It's worth noting, though, that companies expect DevOps to do more more operational tasks than programming or procedure generation.
There aren't a lot of folks who understand how to administer a modern Linux system anymore; even companies using AWS or Rackspace or GAE will need someone versed in the arcane ways of System Administration as they grow.
