Cloud Networking: 2026 Trends

Cloud networking is becoming critical, with 90% of French businesses using multi-cloud in 2026. Trends: cloud-first SASE, multi-cloud interconnect (Megaport, Equinix Fabric), cloud-native Kubernetes networking, eBPF (Cilium), and service mesh. Cloud networking guide for 2026.

2026 trends

• Multi-cloud: 80% of French businesses use 2-4 cloud providers
• Cloud on-ramp: Megaport, Equinix Fabric, PacketFabric
• Cloud-native SASE: Prisma Access, Zscaler, Cato
• Kubernetes networking: Cilium (eBPF) replaces Calico
• Service mesh: Istio, Linkerd for microservices
• Observability: OpenTelemetry standard

Multi-cloud interconnect

• Megaport: cloud fabric with 700+ POPs, connecting AWS, Azure, GCP, Oracle, and IBM
• Equinix Fabric: the world's largest IX + DC cross-connects
• PacketFabric: primarily focused on the USA
• Console-based provisioning in minutes
• Pricing: 1G port ~€500/month, cross-connect €100-500/month

AWS networking

• VPC + subnets + NACLs + Security Groups
• Transit Gateway: hub for multi-VPC/multi-region environments
• Direct Connect: dedicated 1G-100G connectivity
• Cloud WAN: AWS-managed SD-WAN
• AWS App Mesh: service mesh

Azure networking

• VNet + subnets + NSG
• Virtual WAN: hub-and-spoke SD-WAN
• ExpressRoute: 50 Mbps-100G
• Azure Firewall Premium + Front Door
• Private Link for private SaaS connectivity

GCP networking

• VPC (global by default) + Shared VPC
• Cloud Interconnect: Dedicated / Partner
• Network Connectivity Center: multi-cloud
• Cloud Armor: WAF + DDoS
• Cloud NAT: internet egress

Cilium + eBPF

• Replacement for Calico: performance, security, and native observability
• eBPF: Linux kernel programmability without modification
• L3/L4/L7 network policies
• Simplified service mesh without sidecars (Cilium Service Mesh)
• Hubble for observability

Service mesh

• Istio: mature, complex, and market-leading
• Linkerd: lightweight and simpler
• Cilium Service Mesh: sidecar-free
• Consul Connect: HashiCorp
• Use cases: mTLS, observability, and inter-service L7 policies

Cloud-native SASE

Cloud-delivered SASE replaces on-premises hardware:

• Prisma Access: cloud SASE from Palo Alto
• Zscaler Internet Access + Private Access
• Cato SDP + SSE
• Netskope Intelligent SSE
• Cloudflare One

Cloud networking costs

• Egress: 50% lower with a direct on-ramp vs the public Internet
• Inter-region transfers: can account for up to 30% of total cloud costs
• FinOps tools: CloudHealth, Cloudability
• Optimization: typical savings of 10-30%

EU cloud compliance

• Cloud Act (US) vs GDPR: legal conflict
• SecNumCloud (France): certified providers include OVHcloud and Outscale
• Trusted cloud: Bleu, S3NS
• GAIA-X: evolving European project
