When does it make sense to move from Docker Compose / ECS to Kubernetes?

Kubernetes adds significant operational complexity. It is worth it when you have 10+ services, need fine-grained auto-scaling, run multiple teams on shared infrastructure, or require advanced deployment strategies (canary, blue-green). For simpler setups, ECS Fargate or managed platforms are often the better choice.

What is GitOps and should I use it?

GitOps means your Git repository is the single source of truth for cluster state — a tool like ArgoCD watches the repo and reconciles the cluster to match. It enforces discipline, provides a full audit trail of cluster changes, and makes rollbacks instant. We recommend it for all production Kubernetes environments.

How do you handle Kubernetes upgrades?

EKS and GKE provide managed control plane upgrades. We test the upgrade in a non-production environment first, verify addon compatibility (CoreDNS, Kube-proxy, CNI), then perform a rolling node upgrade with PodDisruptionBudgets to ensure zero workload downtime.

What is the difference between a Deployment and a StatefulSet?

Deployments manage stateless pods — any pod is interchangeable. StatefulSets manage stateful applications (databases, Kafka) where each pod has a stable identity, stable network hostname, and persistent volume. Use StatefulSets for anything that needs persistent, ordered pod identity.

How do you manage secrets in Kubernetes?

Native Kubernetes Secrets are base64-encoded, not encrypted. We use External Secrets Operator to sync secrets from AWS Secrets Manager or HashiCorp Vault into Kubernetes Secrets — with RBAC-restricted access and audit logging. Sealed Secrets is an alternative for GitOps-stored encrypted secret manifests.

What We Build

Our Kubernetes Development Services

Kubernetes Cluster Design & Setup

Production-grade EKS, GKE, or self-managed Kubernetes clusters with RBAC, network policies, ingress, and node group auto-scaling.

Kubernetes Migration

Migrate Docker Compose or ECS workloads to Kubernetes with Helm charts, minimal downtime, and a validated rollout plan.

GitOps Workflow Implementation

ArgoCD or Flux-based GitOps pipelines where Kubernetes cluster state is fully declared in Git and applied automatically.

Kubernetes Observability Stack

Prometheus, Grafana, Loki, and OpenTelemetry-based observability — metrics, logs, and distributed traces for every workload.

Kubernetes Security Hardening

Network policies, Pod Security Standards, OPA/Gatekeeper admission controllers, and secrets management with External Secrets Operator.

Kubernetes Managed Support

Ongoing cluster management, version upgrades, on-call response, and capacity planning for production Kubernetes environments.

Technology Advantage

Why Kubernetes for Your Business?

Kubernetes has become the operating system of the cloud. Its declarative model, self-healing capabilities, horizontal scaling, and rich ecosystem make it the default orchestration platform for applications beyond a certain scale or complexity. At Bluejay, we design and manage production Kubernetes clusters on AWS EKS, GKE, and DigitalOcean — including GitOps workflows, observability stacks, and platform engineering for multi-team organisations.

Self-Healing Infrastructure

Kubernetes automatically restarts failed containers, replaces unhealthy pods, and reschedules workloads from failed nodes — reducing MTTR dramatically.

Horizontal Auto-Scaling

HPA and KEDA scale pods based on CPU, memory, or custom metrics (queue depth, request rate). Your application scales to traffic without manual intervention.

Declarative Configuration

Kubernetes resources are YAML-declared and stored in Git. Your entire infrastructure is code — reviewable, versioned, and reproducible.

Zero-Downtime Deployments

Rolling updates, blue-green deployments, and canary releases are first-class concepts in Kubernetes — deploy new versions without taking the service offline.

Multi-Tenancy & Resource Isolation

Namespaces, RBAC, and resource quotas let multiple teams share a cluster safely — each team's workloads are isolated and resource-bounded.

Cloud-Agnostic Portability

Kubernetes workloads are portable across cloud providers. Moving from AWS to GCP or adding a multi-cloud strategy is an infrastructure change, not an application change.

How We Work

Our Processes

We deliver a structured process for seamless project execution. From understanding your requirements to delivering the final solution, we ensure proactive technology services based on your business needs.

Sprint Planning

We break the project into focused sprints with clearly defined goals, priorities, and deliverables, keeping the team aligned and progress visible at all times.

Design & Development

Each sprint delivers working software from UI design to backend logic, with continuous collaboration and daily standups to keep momentum high.

QA & Testing

Every sprint output goes through rigorous quality assurance, automated testing, and code review to ensure reliability, performance, and security.

Review & Iteration

At the end of each sprint, we demo progress to stakeholders, collect feedback, and refine the roadmap to ensure the final product perfectly fits your needs.

Release & Optimization

Once validated, we deploy to production and monitor closely. Post-launch optimizations ensure your product performs at its best from the first day live.
