If you've been in the tech industry for a while, you must have heard of DevOps. The concept of merging development and operations has now become so widespread that it's becoming a standard way to deliver software.

A DevOps engineer is an IT generalist with a wide-ranging knowledge of both development and operations, who possesses interpersonal skills to bridge divides between siloed teams. They work on release engineering, infrastructure provisioning and management, system administration, security, and DevOps advocacy.

DevOps engineers require a broad skill set, including communication and collaboration, system administration, DevOps tools, configuration management, containers and container orchestration, continuous integration and continuous deployment, system architecture and provisioning, coding and scripting, and collaborative management skills.

In this blog post, we will dive deeper into the skills required of a DevOps engineer, as well as delve into the different roles in a DevOps team that all work together to realize the full promise of DevOps.
