So said President Dwight D. “Ike” Eisenhower (more or less). His battles were fought in the trenches, not the technology stacks—but for DevOps teams, the principle holds. No plan survives contact with the enemy.
A plan is a set of instructions you can follow when you understand what needs to be done. Handy when the enemy is one you know, and can plan for. But the Enemy You Know isn’t what (literally) keeps DevOps engineers up at night.
Good DevOps teams competently respond to incidents, outages, and just plain weird stuff happening in their technology stack. Great teams go further—they see around corners, developing the instincts and skills to prepare for the unexpected. At Scalyr we start by reducing the risk of the dreaded 3 am call as much as possible. But we’d be foolish to stop there.
