… If your primary goals are simple mTLS and basic traffic control, I'd recommend Linkerd. Here's a quick comparison: Service Mesh · Best For · Pros · Cons Linkerd · Simplicity · Automatic mTLS, lightweight, easy installation, low operational overhead · Fewer advanced traffic-management features Istio · Advanced traffic management · Rich routing (canary, mirroring, header-based routing), authorization, ecosystem · Steeper learning curve and more operational complexity Cilium Service Mesh · eBPF-first networking · Combines networking, network policy, and service mesh with low overhead · Best if you're already using Cilium; feature set and operational model differ from traditional meshes I'd choose Linkerd if you need: Automatic mTLS between services Simple retries and timeouts Basic traffic splitting (e.g. blue/green or canary) Good observability Minimal maintenance Linkerd is intentionally opinionated and optimized for teams that want security and reliability without managing a large configuration surface.
