I’m Onur Baydaş, a systems and infrastructure engineer based in Turkey. Since 2024 I’ve been designing, running, and troubleshooting on-premises infrastructure: the kind of environments where there is no managed cloud service to fall back on and every layer, from storage to scheduling, is your responsibility.

What I work on

  • Virtualization and storage: Proxmox VE clusters with Ceph, VMware vCenter/ESXi, hyperconverged platforms, TrueNAS/ZFS.
  • GPU infrastructure: NVIDIA GPU servers for AI and research workloads, GPU partitioning with MIG and vGPU, job scheduling with Slurm.
  • Multi-user platforms: Shared Linux systems for many users: user isolation, container access control, and day-to-day operations.
  • Container security: Restricting Docker on shared machines, authorization policies with OPA/Rego, and the gaps those policies can’t close.
  • Identity and operations: Samba-based Active Directory, Kerberos/NFS home directories, centralized logging, and backup monitoring.

What I write about

I write about problems I actually hit in production: the silent failures, the misleading documentation, and what the source code says when the docs don’t. Every post is based on a real incident, tested on a live system, and backed by links to the source.

Writing work

I’m open to freelance technical writing on infrastructure, Linux, virtualization, container security, and GPU/AI infrastructure topics.
