We deliver Talos-based dual-cluster setups (staging and production) on a predictable monthly invoice. The package covers GitOps automation, observability, backups, and incident response. You get a 99.9% monthly SLA, running closer to 99.99% availability in practice. No metered surprises when workloads grow.

Need more capacity? Additional worker nodes follow the same VM sizing as CaffeineStacks blends (Espresso, Lungo, Latte) at 50% of their list price. You scale horizontally without guessing next month's bill.

Is Kubernetes right for you?

Kubernetes is the right choice when you run multiple apps and services that need orchestration, want container-native workflows, and need auto-scaling, rolling updates, and service discovery. Your team is ready to embrace cloud-native patterns and wants the flexibility containers offer.

Not there yet? For simpler setups with one or two apps, our Managed Servers from €200/month are often a better fit. They start faster and scale easily as you grow.

What you get

From €1500/month you get a complete dual-cluster setup:

Cluster Nodes Purpose
Staging 3× Cortado (control plane, 12 GB total)
3× Espresso (workers, 24 GB total)
Updates and changes are tested here first
Production 3× Cortado (control plane, 12 GB total)
3× Lungo (workers, 48 GB total)
Your production workloads run here stable

Need more workers? Add Espresso, Lungo, or Latte nodes as your workload grows. We absorb temporary spikes, when growth is permanent we plan the upgrade together.

Predictable costs, no surprises

With AWS or Azure you pay separately for every NAT gateway, every gigabyte of bandwidth, and every load balancer. Other managed service providers charge €150/hour for support calls. We work differently:

  • Fixed monthly price: €1500/month for your dual-cluster foundation, support included. Extra worker nodes or supporting VMs are billed at 50% of the CaffeineStacks rate.
  • No hidden costs: Bandwidth, load balancers, storage: all included. No surprises on your invoice.
  • Plan upgrades together: Need more workers? We plan together and adjust pricing. Transparent and predictable.

How it works

Dual-cluster approach: Updates and changes go to staging first. When staging runs stable for X days, we automatically roll to production. No surprises, no late-night incidents.

GitOps: Your infrastructure and deployments live in Git. We use Argo CD for automated rollouts. Every change is traceable, every deploy is repeatable.

Monitoring & observability: Prometheus, Grafana, and OpenTelemetry built in. You see what's running, where resources go, and where bottlenecks are. Dashboards for your team, alerts to whoever you want.

Support and management: We upgrade Kubernetes, patch nodes, monitor cluster health, and are available when something goes wrong. We respond quickly when things break, day or night. For urgent platform issues we're available within an hour during business hours. Routine requests are handled within a business day.

Why these technical choices?

Talos Linux: We use Talos as the OS for Kubernetes nodes. Talos is immutable, API-driven, and secure by default. Built specifically for Kubernetes without legacy OS baggage. That means smaller attack surface, predictable updates, and no manual SSH sessions.

Dual-cluster approach: Two identical clusters (staging and production) ensure updates are tested before hitting production. Staging runs the same config, same versions, same workloads. If it works there, it works in production.

Minimum cluster sizing: 3 control plane nodes and 3 worker nodes is the minimum viable HA setup. Add more workers as workload grows. This keeps costs predictable without compromising reliability.

What else is included

  • Managed ingress & TLS: Certificate management, SSL termination, and routing to your services. Automatic cert renewal via Let's Encrypt or your own CA.
  • Secure access: VPN or dedicated circuits to your cluster. RBAC configured, identity integration, and signed container pipelines.
  • Disaster recovery: Backup strategies and tested recovery procedures. Regular failover tests and runbooks for blue/green and canary releases.
  • Capacity planning: Quarterly reviews with buffer for seasonal peaks. We plan growth together, no surprise charges.
  • CI/CD integration: Buildpacks, Maven/Gradle pipelines, and artifact signing. We help integrate your pipeline with GitOps.

Java advantages

Java is where we're at home, so you get extras:

  • JDK base images: Curated images with Temurin and OpenJDK. Automatic updates, triggered rollouts, tested in staging first.
  • JVM tuning: Liveness checks and auto-scaling profiles tailored to Spring Boot, Quarkus, and Jakarta EE.
  • Observability: JVM metrics, request traces, and log correlation. Dashboards with heap usage, GC stats, and thread dumps ready to go.

Who is this for?

Java teams without an SRE department: You want Kubernetes but not the hassle of cluster management. We run the infrastructure, you build features.

Agencies with multiple clients: One cluster for all your Java projects, with namespace isolation and predictable costs. No surprises when a client suddenly needs more resources.

Scale-ups outgrowing simple setups: You've outgrown managed servers but don't want to hire an SRE team yet. This is the middle ground.
