Kubernetes consulting on AWS: when you need EKS, and what good looks like.

IWhat Kubernetes (EKS) consulting on AWS covers

EKS gives you a managed control plane. Out of the box you do not get ingress, autoscaling that fits your workloads, a delivery pipeline or sensible network and account isolation. Bridging that gap, in code you can hand to your engineers, is the work.

• Cluster and account design: Usually one EKS cluster per environment with namespace isolation, in a multi-account AWS Organization so production blast radius is contained. Plus the Kubernetes version and upgrade cadence, managed node groups vs Fargate, and whether EKS Auto Mode should handle nodes and add-ons.
• Networking and the VPC CNI: The Amazon VPC CNI gives every pod a VPC IP, which makes IP exhaustion a real failure mode when subnets are sized wrong. Subnet and CIDR planning, prefix delegation, network policy, and security groups for pods.
• Ingress and load balancing: The AWS Load Balancer Controller provisioning an ALB for HTTP or an NLB for TCP and UDP, with TLS through ACM, WAF and shared ingress so you do not pay for one load balancer per service.
• Autoscaling: Karpenter and HPA: The Horizontal Pod Autoscaler (and KEDA for event-driven scaling) scales pods. Karpenter provisions right-sized EC2 nodes, consolidates underused ones and mixes Spot with On-Demand. Tuning it is where much of the savings come from.
• GitOps delivery: Argo CD or Flux reconciles the cluster to manifests in Git, so every change is reviewed and revertible. Plus image scanning, ECR, and progressive delivery with Argo Rollouts so a bad deploy rolls back on its own.
• Observability: Amazon Managed Prometheus and Grafana, CloudWatch Container Insights or Datadog, a log pipeline, OpenTelemetry traces, and alerts on symptoms users feel rather than every CPU spike.
• Security: Namespace-scoped RBAC, IRSA or EKS Pod Identity for least-privilege AWS access with no static keys, External Secrets with Secrets Manager, network policies and pod security standards. This is the surface SOC 2, ISO 27001, HIPAA and PCI reviews look at.
• Cost: Right-sized requests and limits, Karpenter consolidation, Spot for fault-tolerant work, Savings Plans for the baseline, and per-namespace cost visibility. EKS also charges a cluster fee of $0.10 an hour on standard support ($0.60 on extended support), so stay on supported versions.

IIDo you need Kubernetes? The honest answer

The most valuable thing a good consultant can tell you is that you do not need Kubernetes yet. Its generality is why it is heavy to run: more moving parts, version upgrades, a second permission system and add-ons to keep current.

IIIThe common EKS mistakes consultants get paid to fix

Most EKS rescue work is the same handful of mistakes from a cluster stood up under deadline. If several sound familiar, the job is hardening what you have, not a rebuild.

• VPC CNI IP exhaustion: Subnets sized for a few nodes, then pods stop scheduling under load. Fixed with CIDR planning, prefix delegation or a CNI change.
• Cluster Autoscaler instead of Karpenter: A fixed set of node groups is slow to add capacity and wastes money. Karpenter with consolidation and Spot is often the highest-return change.
• Missing or wrong requests and limits: The scheduler packs blindly, nodes get noisy, and careless limits cause OOM kills or throttling. Right-size from real usage.
• One ALB per service: Without shared ingress through the Load Balancer Controller, every service gets its own load balancer.
• Pods using the node role or static keys: Over-privileged or leakable credentials, a classic audit failure. IRSA or Pod Identity fixes it.
• kubectl apply as the deploy process: No review, no audit trail, no clean rollback, and clusters drift onto unsupported versions. GitOps with Argo CD and a managed upgrade cadence fix it.
• Alerts on noise, not symptoms: Pages on raw CPU bury on-call while real incidents slip through. Alert on latency, errors and saturation tied to SLOs.
• No resilience or isolation basics: Missing PodDisruptionBudgets, probes, topology spread, namespaces and quotas mean a routine node recycle takes a service down.

IVWhen EKS vs ECS vs Fargate vs Lambda

Fargate is a capacity mode that runs under both ECS and EKS, so the real choice is usually orchestrator (ECS or EKS) and capacity (Fargate or EC2), with Lambda when you do not want containers at all.

VHow to vet a Kubernetes or EKS consultant

The gap between someone who has "used Kubernetes" and someone who has run EKS through real incidents and audits is large, and it does not show on a résumé. Strong practitioners answer with specifics and trade-offs.

• Ask "when would you not use Kubernetes?": A credible consultant describes the ECS, Fargate and App Runner cases right away.
• Probe the VPC CNI and IP math: How do they size subnets and avoid IP exhaustion? Vague answers mean little EKS experience at scale.
• Ask how they would cut this cluster's cost: You want Karpenter consolidation, right-sized requests, Spot and Savings Plans, not "bigger nodes".
• Ask how pods get AWS permissions: IRSA or Pod Identity with namespace-scoped RBAC, not the node role.
• Ask how code reaches the cluster: GitOps with Argo CD or Flux, image scanning and automated rollback.
• AWS partner status and EKS references: Named EKS production references. Partner status also matters for funding: only an AWS partner can file MAP, POC or IW funding for your project.
• An outcome you own: A defined deliverable and timeline, with the Terraform, OpenTofu or CDK plus runbooks handed to your team.

VIWhat Kubernetes consulting costs

Rough 2026 ranges, not quotes. Independent senior EKS specialists and boutique firms often bill $150 to $300+ an hour; larger consultancies more. Good partners scope to an outcome, not hours.

• Greenfield EKS design and build: A production-ready cluster with the full scope above is commonly a 3 to 8 week project, often in the low to mid five figures as a fixed scope, depending on depth and the number of environments.
• Rescue or hardening: Fixing the mistakes above on an existing cluster is usually shorter and cheaper, because the work is targeted.
• Ongoing or fractional support: A senior EKS engineer on retainer for upgrades, on-call backup and cost work a few days a month.

VIIHow CloudRoute gets the EKS work done

Hiring for Kubernetes is slow and hard to judge if you lack the skill in-house. CloudRoute matches you with one vetted EKS partner instead.

• You describe the situation: A greenfield EKS build, a fragile or expensive cluster, or a second opinion on EKS vs ECS, plus your stack, region and compliance needs.
• We match one vetted partner: A partner with EKS production references and AWS partner status. We reply within 24 hours; your matched partner reaches out within 5 business days.
• The partner scopes an outcome: A discovery call, then a defined deliverable and timeline. The partner also checks whether any of the work qualifies for MAP, POC or IW funding. You decide whether to proceed.
• You own what is built: Infrastructure as code, GitOps manifests, dashboards and runbooks, handed to your team.

CloudRoute is free for startups. Partners pay CloudRoute a monthly membership plus 10% of AWS-approved funding.
