Container orchestration

Kubernetes reconciliation for workloads that need a platform

Orchestration Fit

When Kubernetes Orchestration Fits

  • You are orchestrating complex microservices architectures (20+ independent services) requiring automated inter-service networking, canary rollouts, and self-healing.
  • Workloads require custom scheduling policies, multi-AZ topology spread constraints, and dynamic autoscaling based on queue metrics (KEDA).
  • Your platform requires multi-cloud or hybrid portability with standardized declarative GitOps deployments (ArgoCD / Flux).
  • You are running stateful distributed engines (MongoDB, Elasticsearch, Kafka) requiring deterministic storage binding via StatefulSets.
Complexity Boundary

When Cloud Run, ECS Fargate or PaaS Fits Better

  • You are deploying a single monolithic backend or early-stage startup app where managed serverless containers (Cloud Run, ECS Fargate) eliminate cluster management overhead.
  • Your team lacks dedicated platform engineering bandwidth to maintain cluster upgrades, node pool patching, and CNI networking.
  • You are serving a static or server-rendered frontend application where serverless PaaS simplifies edge delivery (choose Vercel).
Engineering Rigor

Kubernetes Production Platform Best Practices

01. PRINCIPLE

Probe Discipline

Distinguishing startup probes (slow initial boot), liveness probes (process deadlock restarts), and readiness probes (removing unready pods from traffic rotation).

02. PRINCIPLE

Resource Guarantees

Setting explicit CPU/Memory requests and limits on every single container to prevent Node memory starvation and unpredictable OOMKilled cascade failures.

03. PRINCIPLE

PodDisruptionBudgets

Mandating PDBs (e.g. minAvailable: 2) on all production workloads to ensure cluster node drains and control plane upgrades cause zero application downtime.

04. PRINCIPLE

GitOps Declarative State

Managing 100% of cluster configurations via GitOps pipelines (ArgoCD), strictly prohibiting direct manual kubectl apply modifications in production.

Frequently Asked Questions About Kubernetes Orchestration

Is Kubernetes required for every application?

No. Many workloads run well on simpler compute or managed app platforms. Use Kubernetes when orchestration complexity is justified.

Does autoscaling guarantee lower cost?

No. Autoscaling can reduce waste or increase spend depending on signals, limits, and idle capacity.
