Audit-grade rigor

Namespace-level Kubernetes cost allocation with OpenCost: run showback and graduate to chargeback on bare-metal clusters where no cloud billing API exists.

Run a self-hosted certificate authority for internal Kubernetes names: step-ca as a private ACME server, cert-manager as the client, no CT-log leakage.

MIG gives hard, isolated GPU partitions; time-slicing shares one context with none; DRA makes fractional GPU scheduling a first-class Kubernetes primitive.

Model residency is not agent residency. A self-hosted MCP gateway and LiteLLM proxy keep tool-calls, keys, and PII inside your own network boundary.

Schrems II turns six today. The EU-US Data Privacy Framework is under fresh challenge, and CLOUD Act reach means US-parent clouds remain a live transfer risk.

Digital sovereignty is not a slogan but five engineering control layers — compute, data, keys, identity, supply chain — each mapped to a testable control.

Operationalizing the DPDPA: a consent flow, data-principal access and verifiable erasure across your stores, and a breach workflow on the DPB's clock.

CERT-In's 2022 Directions as engineering constraints: six-hour incident reporting, 180 days of logs held inside India, and a synchronized NIC/NPL time source.

The engineering read of India's DPDP Act 2023: data fiduciary duties, cross-border transfer, and the Significant Data Fiduciary tier as infrastructure.

The EU AI Act's high-risk AI system obligations — Article 12 logging, conformity assessment, post-market monitoring — mapped to on-prem inference infrastructure.

Run GitHub self-hosted runners on Kubernetes with actions-runner-controller (ARC): ephemeral, autoscaling, network-isolated CI compute you own — without leaving GitHub.

How a covered entity runs a HIPAA-compliant LLM on-premises: PHI never leaves your perimeter, no third-party BAA to manage, every inference logged for audit.

Kubernetes runtime threat detection with eBPF: Falco for broad MITRE ATT&CK detection, Tetragon for in-kernel enforcement, alerts piped to a self-hosted SIEM.

SPIFFE/SPIRE issues cryptographic, attested workload identity — X.509 and JWT SVIDs — so Kubernetes services get mutual TLS and zero long-lived static secrets.

An engineering guide to running production PostgreSQL on Kubernetes with CloudNativePG: HA streaming replication, WAL archiving and PITR to your own object store, automated failover, and exit from managed-DB lock-in.

How AMD SEV-SNP, Intel TDX, and Confidential Containers (CoCo/Kata) protect data-in-use on Kubernetes — and how remote attestation gates key release so workloads only run on verified hardware.

A sovereign DR architecture for Kubernetes — Velero plus CSI data-mover for apps and volumes, etcd snapshots for cluster state, cross-region restore to a standby cluster, and restore drills that turn RPO/RTO from a promise into evidence.

The EU AI Act, NIS2, and DORA are one architecture constraint, not three checklists — the technical evidence for why hyperscaler SaaS cannot satisfy them.

In our engagements, a base Ubuntu 22.04 install consistently shows 40–50x more critical/high CVEs than an equivalent Talos Linux node. Here is the structural reason the gap exists — and why retrofitted hardening cannot close it.

Canary and blue-green on Kubernetes with Argo Rollouts: metric-driven AnalysisRuns, automated rollback, Gateway API traffic shaping, and audit-grade promotion gates.

How to replace Datadog and New Relic with a self-hosted OpenTelemetry + Prometheus + Loki + Tempo + Grafana stack on Kubernetes — retaining data sovereignty, audit-grade retention, and eliminating per-GB ingestion costs.

How to run self-hosted LLM inference on Kubernetes with vLLM at production grade: GPU sizing, cost crossover analysis, audit logging for EU AI Act compliance.

A complete guide to building a Kubernetes supply chain security pipeline: SBOM generation with Syft, SLSA L3 provenance via slsa-github-generator, Sigstore keyless signing, and Kyverno admission enforcement.

Policy lifecycle — versioning, testing, exceptions, reporting — is 80% of the problem. Here is how to build a Kyverno governance layer that scales organizationally.

Vault is the right backend, not the right interface. ESO + dynamic credentials + etcd encryption eliminate long-lived secrets from Kubernetes clusters.

Golden paths without admission enforcement are just suggestions. Learn why DX and policy are the same design problem — and how to build a platform where the golden path is the only path that works.
