• Why use Kubernetes

  • Best for running multiple processes/servers/jobs with redundancy and load balancing
  • Enables infrastructure-as-code configuration for service relationships
  • Outsourced infrastructure management via cloud providers (e.g., Google Kubernetes Engine)

• What they use

  • Core resources: Deployments (with rolling updates), Services (ClusterIP/LoadBalancer), CronJobs
  • Configuration: ConfigMaps and Secrets via Pulumi (TypeScript) instead of raw YAML
  • Cautious adoptions: StatefulSets for limited persistence, RBAC only when necessary

• What they avoid

  • Hand-written YAML and Helm charts ("fragility for no gain")
  • Operators, custom resources, service meshes, and most third-party controllers
  • Local k8s stack replication (prefer Docker Compose for local dev)

• Key insights

  • "A human should never wait for a pod" - unsuitable for interactive workloads requiring fast startup
  • Use managed databases/storage for critical data instead of k8s volumes
  • Alternatives like Railway/Render may be better for simpler SaaS apps
  • Recently adopted Ingress controllers for Cloud Armor integration despite initial reservations

BP, Shell, Chevron, ExxonMobil et TotalEnergies werden an ihre Aktionäre für das Jahr 2023 mehr als 100 Milliarden Dollar Dividenden auszahlen und damit den Rekord des Vorjahres noch übertreffen. Ursachen für die Rekordprofite sind der Krieg in der Ukraine und die Umwälzungen auf den Weltenergiemärkten. Die Konzerne gehen weiterhin von der Profitabilität ihres Geschäfts aus. Weltweit leiden ärmere Haushalte unter den gestiegenen Energiekosten. https://www.liberation.fr/environnement/climat/industries-fossiles-les-petroliers-arrosent-leurs-actionnaires-de-dividendes-records-20240102_KETOFCVOT5ANLNWCBWMGNYOE7I/

tl;dw (best DevOps tools in 2023)

1. Low-budget cloud computing : Civo (close to Scaleway)
2. Infrastructure and Service Management: Crossplane
3. App Management - manifests : cdk8s (yes, not Kustomize or Helm)
4. App Management - k8s operators: tie between Knative and Crossplane
5. App Management - managed services: Google Cloud Run
6. Dev Envs: Okteto (yeap, not GitPod)
7. CI/CD: GitHub Actions (as it's simplest to use)
8. GitOps (CD): Argo CD (wins with Flux due to its adoption rate)
9. Policy Management: Kyverno (simpler to use than industry's most powerful tool: OPA / Gatekeeper)
10. Observability: OpenTelemetry (instrumentation of apps), VictoriaMetrics (metrics - yes not Prometheus), Grafana / Loki (logs), Grafana Tempo (tracing), Grafana (dashboards), Robusta (alerting), Komodor (troubleshooting)
