The three verticals
The blog is organised into three training verticals aligned with the itineraries of lo0 (training) and with the projects of Fibercli (sovereign infrastructure and cybersecurity consultancy):
- AI — LLMOps in production, LLM inference, data and RAG, training, evals, guardrails and observability.
- Kubernetes — lightweight distributions (RKE2), eBPF networking with Cilium, observability with Hubble, runtime security with Tetragon.
- Networking — Huawei EVPN/VXLAN, MikroTik RouterOS, Ubiquiti UniFi, HCIA Datacom certification.
The three verticals share a common denominator: technical content aimed at real operation, not at marketing.
Every article on the blog is published in Spanish and in English. The language selector in the header switches between the two versions of whatever page you are on.
Where to start, by profile
If you are here for the AI vertical
If you have never worked with LLMs in production, two posts, in order:
- MLOps for LLMs in 2026 — the landscape.
- The six-stage LLMOps pipeline — the master map.
If you already operate an LLM system and want to go deeper:
- Anatomy of an LLM request in production — one real request crossing the six stages. It is the complete tour.
If you are weighing OSS against cloud:
- The parallel catalogue: OSS versus hyperscalers (AWS, GCP, Azure) — equivalences stage by stage.
- The OSS catalogue for LLMOps in six stages, tool by tool — what each tool does, its licence and its production gotcha.
If you are here for the Kubernetes vertical
- RKE2 with Cilium BGP — the starting point for the on-premise cluster.
- Kubernetes cluster: CNI networking — the network plane inside the cluster.
- Hubble: eBPF observability and Tetragon: runtime security — observability and auditing with eBPF.
If you are interested in how LLMs are served on K8s, the posts vLLM on Kubernetes, LLM operators on K8s and Multi-tenant GPU cluster live in the AI vertical but carry the kubernetes tag for cross-visibility.
If you are here for the Networking vertical
- EVPN / VXLAN on Huawei — a modern datacenter fabric.
- MikroTik RouterOS 7: firewall and Ubiquiti UniFi: VLANs and firewall — configuration by vendor.
- Huawei HCIA Datacom: tips — certification preparation.
The canonical post for each vertical
| Vertical | Recommended post |
|---|---|
| AI | Anatomy of an LLM request in production |
| Kubernetes | RKE2 with Cilium BGP |
| Networking | EVPN/VXLAN on Huawei |
If you would rather see the whole picture at once, the blog map orders everything published into the ten layers that separate the utility feed from the token served to a user.
How this blog is built
It is the technical blog of lo0 (training) and Fibercli (sovereign infrastructure and cybersecurity consultancy). The editorial rule:
- No marketing, no hype. Figures come with their source or a derivable calculation.
- When something is an estimate, it says so.
- On-premise hardware always in generic market configurations, never specific internal infrastructure.
- Bidirectional cross-links: the blog is a navigable network, not a chronological sequence.
