Secure, observable microservices communication with Istio on Kubernetes.
Fremen Consulting implements Istio service mesh on Kubernetes — mTLS encryption, traffic routing, circuit breaking, distributed tracing, and canary deployments for microservices architectures requiring advanced networking control.
Problems we solve for businesses like yours
Microservices communicate over plain HTTP inside the cluster, failing compliance requirements and exposing internal API traffic to lateral movement attacks.
Rolling updates with no canary routing mean bad releases affect 100% of users before rollback — with no automatic circuit breaking on failing dependencies.
Debugging latency across ten microservices requires manual log correlation without automatic trace propagation and service topology visualization.
Solutions tailored to your industry and growth goals
Production Istio deployment with strict mTLS, authorization policies, and incremental rollout using sidecar injection for existing workloads.
VirtualService and DestinationRule configuration for canary routing, circuit breaking, retries, timeouts, and fault injection testing.
Jaeger or Zipkin distributed tracing, Kiali service topology dashboards, and Prometheus metrics for golden signals per service.

Measurable outcomes from projects in this space
Istio strict mTLS rollout across thirty microservices achieved compliance requirements and enabled canary deployments with zero-downtime releases.
Clear answers to common questions in this industry
Istio makes sense when you have ten or more microservices requiring mTLS, advanced traffic routing, or distributed tracing — and your team has Kubernetes operational maturity. For simpler setups, ingress controllers may suffice.
Istio adds latency via Envoy sidecar proxies — typically 1-3ms per hop. We tune sidecar resources, implement ambient mesh mode where appropriate, and measure impact before full rollout.
Yes. Istio works via sidecar injection without application code changes. mTLS, routing, and tracing are configured at the infrastructure layer through Kubernetes annotations and Istio CRDs.
Istio offers richer traffic management and a larger ecosystem; Linkerd is lighter weight with lower resource overhead. We assess your requirements and recommend the appropriate mesh.
Pilot installation with one application takes two to four weeks. Organization-wide rollout with mTLS and observability typically takes eight to sixteen weeks including team training.
