Why DevOps Skills Are Critical Today

Before diving into the specific skills, it‘s important to level-set on why DevOps has become such a strategic imperative. Four driving factors:

Need for Speed – In the digital economy, rapid delivery of software innovations is key to delight customers and beat competition. Faster time-to-market requires faster build-test-release cycles.

Deployment Velocity – Agile, cloud and automation has increased deployment frequency from months to days or hours. Frequent production changes need mature practices.

Infrastructure Complexity – Hybrid multi-cloud environments with containers, microservices and orchestration has exploded infrastructure complexity with interdependencies.

Need for Collaboration – Development, QA, InfoSec and Operations teams have historically worked in silos. DevOps brings these diverse disciplines together leveraging practices like "shifting left" and shared ownership.

These market realities have put the spotlight firmly on the DevOps Engineer role that straddles across domains from code to cloud and beyond.

The DevOps engineer skills spectrum spans both technical hard skills as well as soft people-focused skills. Let‘s explore them in detail:

Critical Soft Skills

While technical skills are mandatory, studies show that people and communication capabilities are most critical for DevOps engineers.

Why are soft skills so invaluable?

DevOps engineers engage daily with diverse stakeholders like developers, testers, product owners, InfoSec and Ops teams. They play the conduit translating business needs into technical implementations.

"We implemented robust infrastructure monitoring not to collect metrics but to improve customer experience."

They must collaborate seamlessly with empathy, clarity and tact to enable organizational agility.

Here are 3 vital soft skills every DevOps engineer must cultivate:

1. Effective Communication
