Container Orchestration Optimization — Make Your ECS or K8s Cluster Production-Ready
Running containers in production requires more than <code>docker run</code>. Service discovery, health checks, rolling deployments, resource limits, log aggregation, secret injection, and networking all need to be configured correctly. We optimize your container orchestration platform — ECS, EKS, or plain Kubernetes — so deployments are reliable, scaling is automatic, and failures are detected and recovered from without human intervention.

We implement, you ship. Async, documented, done in days.
Common Orchestration Problems
Container orchestration platforms handle a lot of complexity, but they expose it through configuration that is easy to get wrong. Common problems we fix:
Health check misconfiguration: Health checks that are too aggressive (marking containers unhealthy during slow startups) or too lenient (not detecting actual failures for minutes). The result is either deployment failures (new containers killed before they finish starting) or prolonged outages (dead containers receiving traffic).
Resource allocation: CPU and memory limits that are either too tight (containers get throttled or OOM-killed under normal load) or too loose (wasting cluster capacity). On ECS Fargate, you pay for the CPU/memory you request, so over-requesting is literally overpaying.
Deployment configuration: Rolling deployments without proper minimum healthy percent, deregistration delay, or drain timeout. The result is dropped requests during deployments because old containers are terminated before in-flight requests complete, or new containers receive traffic before they are fully initialized.
Logging and observability: Container logs going to default stdout with no aggregation, no structured format, and no correlation between services. When something breaks, debugging requires SSH-ing into individual hosts and grepping through log files — exactly the problem containerization was supposed to solve.
Our Orchestration Optimization
Health Checks: We configure startup probes (wait for slow-starting containers), liveness probes (detect and restart stuck containers), and readiness probes (remove containers from load balancing during initialization or degradation). For ECS, we configure ALB health checks with appropriate intervals (15s), thresholds (3 consecutive checks), and the correct health check path that validates application readiness, not just TCP connectivity.
Deployment Strategy: We configure rolling deployments with minimumHealthyPercent: 100 and maximumPercent: 200 so new containers start before old ones stop. Deregistration delay is set to match your application's drain time (typically 30-60s). For Kubernetes, we configure maxUnavailable: 0 and maxSurge: 25% with pod disruption budgets to maintain capacity during upgrades. Deployment readiness gates prevent traffic from reaching pods that have not passed all health checks.
Service Discovery: On ECS, we configure AWS Cloud Map for service-to-service communication so services find each other by name rather than hardcoded IPs. On Kubernetes, we use native Service resources with headless services for stateful workloads. We configure DNS caching (e.g., NodeLocal DNSCache) to reduce DNS lookup latency for inter-service calls.
Observability: We configure structured JSON logging with request IDs, trace IDs, and service names. Logs are shipped to CloudWatch, Loki, or your preferred aggregation platform. We set up distributed tracing with OpenTelemetry so you can follow a request across services and identify exactly where latency is introduced. Dashboards show per-service request rate, error rate, and latency (the RED method).
