Ricard Bejarano: The SRE At Home

Home labbing serves as a powerful catalyst for professional growth and technical mastery within the site reliability engineering field. Ricard Bejarano, a lead SRE at Cisco’s Thousand Eyes and author of *The Home Lab Handbook*, explains how transitioning from Docker to Kubernetes in a personal environment directly translates into high-demand enterprise skills and career advancement. Beyond professional development, home labs enable complete digital sovereignty, allowing individuals to host private blogs, automate home security via Home Assistant, or manage specialized services like Dungeons and Dragons servers without relying on third-party uptime. Modern containerization engines have lowered the barrier to entry, making it possible to repurpose affordable or salvaged hardware, such as old Intel NUCs or damaged Mac Minis, into functional servers. This culture of tinkering, supported by robust communities like the Home Lab subreddit, transforms discarded electronics into sophisticated platforms for continuous learning and personal utility.
