For secure service-to-service communication across AWS/Azure/GCP, I’d separate the problem into two layers:

Multi-cloud underlay: private connectivity, routing, segmentation, failover.
Service identity/security: mTLS, workload identity, authorization, service discovery.

Main options

Approach	Best fit	Security model	Operational complexity
Cilium Cluster Mesh	Kubernetes-heavy multi-cloud	Identity-based policies + encryption + mTLS	Medium
Tetrate Service Bridge / Istio	Enterprise multi-cloud microservices	mTLS + identity-aware authorization + centralized policy	Medium–High
Google Cloud Cross-Cloud Network + Service Mesh	GCP-centered environments	Private encrypted connectivity + mesh mTLS/authorization	Medium
Aviatrix + service mesh	Large heterogeneous cloud networks	Network segmentation/firewall + mesh security	Medium
Native cloud networking only	Simpler L3/L4 connectivity	VPC/VNet controls, VPN/interconnect, firewalls	Low initially, weaker service-level identity

My architectural recommendation

If you're running Kubernetes across multiple clouds, I'd seriously consider:

Cilium + Cluster Mesh + WireGuard/IPsec + Gateway API

Cilium provides cross-cluster service discovery/load balancing and identity-based policies rather than relying purely on IP addresses. Its service-mesh functionality also supports workload encryption and L7 authorization.

One important caveat: Cilium Cluster Mesh effectively puts connected clusters into a shared trust domain, so I'd only connect clusters that you genuinely consider mutually trusted.

If you need a more enterprise/service-mesh-centric platform, Tetrate Service Bridge is worth evaluating. It is built around Istio/Envoy and provides centralized mTLS, identity-aware authorization, traffic management, and connectivity across containers, VMs, and serverless environments.

For a GCP-heavy environment, Google Cloud's combination of Cross-Cloud Network + Cloud Service Mesh is compelling: Cross-Cloud Network handles the private multicloud connectivity layer, while Cloud Service Mesh handles service identity, mTLS and authorization. Google explicitly supports hybrid/multicloud deployments.

The architecture I'd aim for

                  ┌───────────────┐
                  │ Identity / CA │
                  └───────┬───────┘

   └────┬────┘                         └────┬────┘
        │                                   │
        │          service discovery        │
        └──────────────┬────────────────────┘
                       │
                  ┌────▼────┐
                  │   GCP   │
                  │   GKE   │
                  │ Cilium  │
                  └─────────┘

The key is not to treat "private network" as equivalent to "secure service-to-service." Your underlying VPN/interconnect/transit network provides reachability; workload identity + mTLS + authorization determines which service is actually allowed to talk to which other service. Google makes the same distinction in its service-mesh security documentation.

If you tell me your stack (e.g. AWS EKS + Azure AKS + GCP GKE, number of clusters, and whether you need VM-to-service traffic too), I can lay out a concrete reference architecture and compare Cilium vs Istio/Tetrate vs Aviatrix for it.
