Cloud/Virtualization

With years of hands-on experience in Linux, Cloud, VoIP, and Virtualization, I specialize in open-source systems and have been a dedicated ZABBIX user since version 2.0.

This blog is where I document real-world infrastructure engineering — monitoring, automation, high availability, and the small technical details that make systems reliable.

At the same time, I am deeply interested in Web design.
I believe great systems should not only be stable and scalable, but also intuitive and elegant.

Based in Japan, I am actively engaged in the open-source community and always open to global collaboration.
