What are some common challenges a Linux admin faces when managing large-scale server environments?

Linux Admins working in large-scale environments often encounter challenges such as maintaining system uptime during updates, ensuring consistent configuration across multiple servers, and quickly responding to security threats. Balancing automation with manual oversight is crucial, as scripts and management tools like Ansible or Puppet can introduce new complexities. Additionally, collaborating with development and security teams to implement changes without disrupting services requires strong communication and problem-solving skills.
