[职业发展]哪块儿更有意思更有job security

layer 1: app, product
layer 2: identity, Auth/Security
layer 3: data management, compliance
layer 4: compute, network, storage

虽然就算长期只写crud也不免跟各层打交道，深耕的话，还是想听听大神们的理解, 最好有near-term job security和long-term potential角度

Or growth, interesting work etc.

越底层job security越好把。但是短期来看坑也少。
