Production Kubernetes for SaaS — Without the K8s Tax
Multi-tenant cluster architecture, GitOps deploys, and container security operated by engineers who do this every day. For SaaS teams who need K8s but don't want a 3-engineer platform team running it.
Compliance Frameworks
Our SaaS DevOps solutions are designed to satisfy all relevant compliance requirements for your industry.
Managed Kubernetes for SaaS is a service where an external team designs, operates, and secures your production Kubernetes clusters — including multi-tenant isolation, autoscaling, GitOps deploy pipelines, and container security — so your engineers can deploy services without becoming Kubernetes experts. It's the right model for SaaS companies that have outgrown ECS or simple VMs but haven't yet hit the scale that justifies a dedicated platform team.
The Challenges SaaS Companies Face
Kubernetes gaps create real risk for saas organizations. Here is what we hear from clients before they work with us.
Quarterly K8s upgrade gets postponed indefinitely because nobody has the time or confidence to do it safely
Autoscaling misconfigurations cause outages during enterprise customer traffic spikes
Enterprise security reviews flag unclear container provenance and missing runtime detection
Multi-tenant isolation in shared clusters breaks under load, leaking workload to neighboring tenants
What PlatOps Delivers for SaaS
Concrete deliverables, scoped for your stack and operating model — not a list of generic service features.
Multi-tenant cluster architecture
Shared EKS or GKE cluster with namespace-per-tenant isolation, NetworkPolicy enforcement, and resource quotas tuned to plan tier. Where enterprise customers demand dedicated clusters, we provision and operate them under a parent management cluster (Crossplane or Cluster API).
GitOps deploy pipeline
Argo CD or Flux configured against your repo structure, with sync waves for ordered rollouts, ApplicationSets for multi-environment patterns, and automated rollback on health-check failure. Engineers deploy via PR; no kubectl access required.
Autoscaling that matches your traffic shape
HPA for stable web traffic, KEDA for queue-driven workers, Karpenter or Cluster Autoscaler for node provisioning. We tune scaling policies quarterly based on actual traffic histograms, not best-guess CPU thresholds.
Container + cluster security baseline
PodSecurity Standards (restricted profile by default), image scanning at registry (Trivy or Snyk), runtime threat detection (Falco), network policies enforced default-deny with explicit allowlists. Maps directly to SOC 2 CC6 (logical access) and CC7 (system operations).
Cluster lifecycle ownership
We handle Kubernetes version upgrades quarterly, with a documented blue-green or rolling strategy depending on your workload tolerance. CNI, ingress controller, and platform addon upgrades coordinated separately. Your team approves the upgrade window; we execute.
Observability + on-call
Prometheus + Grafana stack tuned for K8s-specific signals (pod restarts, OOMKills, scheduling failures, cluster-autoscaler events) layered onto your existing application observability. PlatOps engineers take first-line on-call for cluster-level alerts.
Why SaaS Companies Reach Out
Most B2B SaaS teams arrive at Kubernetes for one of three reasons: an enterprise customer demanded multi-tenant isolation that ECS or single-VM-per-customer can't deliver cleanly; their workloads got polyglot enough that a unified orchestrator started looking attractive; or a Chief Architect was hired who wanted K8s on principle. The honest assessment after a year: K8s does deliver, but the operational tax — cluster upgrades, IAM-for-RBAC, ingress complexity, observability fan-out, certificate rotation, and the per-quarter "why is the autoscaler doing that" debugging session — eats 25–40% of platform-engineering time.
PlatOps runs production Kubernetes for SaaS the way teams who do nothing else but K8s run it. We design the cluster topology around your tenancy model (shared cluster with namespace isolation for SMB tier, dedicated cluster per enterprise customer where needed), wire up GitOps via Argo CD or Flux so deploys are pull requests not kubectl invocations, configure autoscaling that actually responds to your traffic shape (HPA for steady, KEDA for event-driven, Karpenter for pod-level node provisioning), and operate a container security baseline that satisfies SOC 2 auditors on the first pass.
The scope: cluster lifecycle (creation, upgrade, retirement), workload onboarding (Helm chart authoring, network policies, PodSecurity standards), autoscaling tuning, observability (Prometheus + Grafana or Datadog Kubernetes integration), and runtime security (Falco or equivalent). Your engineers write Dockerfiles and Helm values; we own the cluster.
Typical engagement
B2B SaaS, 30-50 engineers, mid-tier SaaS revenue, multi-tenant on EKS
Industry averages we plan around: cluster onboarding (read-only audit through full operational handoff) typically takes 6–10 weeks. Initial cluster cost optimization in months 1–3 reduces compute spend 20–35%. Pod-restart rate drops 50–70% in the first quarter as resource limits and probes get rationalized. Annual K8s management cost: $120k–$240k depending on cluster count and traffic complexity, vs the loaded cost of a 2-engineer platform team ($500k+).
Composite profile based on industry benchmarks. Specific outcomes vary by environment, scope, and current security posture.
What You Get with PlatOps
Specific, measurable outcomes for saas organizations.
GitOps deploys with automated rollback — production deploys are PRs, not kubectl invocations
Quarterly K8s upgrades happen on schedule with documented blue-green or rolling strategy
Multi-tenant namespace isolation with NetworkPolicy enforcement that survives enterprise security reviews
Cluster cost typically reduced 20-35% in first 90 days through right-sizing and Karpenter
Container security baseline (PodSecurity, image scanning, runtime detection) maps directly to SOC 2 controls
Compliance Frameworks, In Detail
What each framework requires and what PlatOps does about it — not just a badge wall.
SOC 2 Type II
Kubernetes-specific controls auditors expect: image provenance and scanning, runtime threat detection, network segmentation, change management for cluster configuration, and access logging via Kubernetes audit logs. We document and operate all of these as part of cluster management.
ISO 27001
Annex A.12 (operations security) and A.14 (system development) controls land directly on K8s practices. Our cluster management produces evidence streams that cover both ISO 27001 and SOC 2 simultaneously.
GDPR / CCPA
Multi-tenant K8s with namespace isolation supports data-residency requirements via cluster placement (regional EKS in eu-west-1 for EU tenants). We design tenant onboarding to support data-localization requirements where customers demand them.
Frequently Asked Questions
Do we keep our own K8s expertise in-house?
We strongly recommend at least one in-house engineer who understands enough K8s to read manifests, debug a failing pod, and have a real conversation with us about architecture. That's typically achievable on top of normal application engineering — not a dedicated hire. We're not the only ones who should know how your cluster is built.
Shared vs. dedicated clusters per tenant — which is right?
Below ~50 paying tenants, shared cluster with namespace isolation is right. Above that, or when enterprise customers require dedicated clusters per their security review, we add dedicated clusters per enterprise tenant managed alongside the shared one. The decision is per-customer, not all-or-nothing.
What about Kubernetes-as-a-Service offerings like Vercel or Render?
If your workload fits a PaaS, take the PaaS — it's simpler. Managed K8s makes sense when you have stateful workloads, custom networking requirements, multi-tenant isolation needs, or compliance requirements that PaaS providers don't satisfy out of the box.
Will you migrate us off ECS or VMs to K8s?
Yes — migration is a 3–6 month engagement depending on workload count and stateful complexity. We do not push K8s on every customer; if your current architecture works, we'll tell you. Migration is right when current infrastructure is blocking enterprise deals or developer velocity.
What's the realistic minimum scale for managed K8s to make sense?
Below ~10 services and ~5 environments, plain ECS or even Heroku is usually right. Above that, K8s economics start to win — and managed K8s economics specifically win when you'd otherwise need a dedicated platform engineer.
