Best Practices for Hybrid Cloud Networking

  • As part of the “Best Practices” series by Uplatz

 

Welcome to the connected-cloud edition of the Uplatz Best Practices series — where public and private clouds don’t compete, they cooperate.
 Today’s spotlight: Hybrid Cloud Networking — enabling seamless, secure connectivity between on-premises data centers and cloud environments.

🌐 What is Hybrid Cloud Networking?

Hybrid Cloud Networking refers to the architecture and practices that interconnect private (on-prem) infrastructure with one or more public clouds (AWS, Azure, GCP), creating a unified environment.

It powers:

  • Gradual cloud migration

  • Data residency and compliance controls

  • Disaster recovery and burst workloads

  • Edge computing or legacy systems integration

✅ Best Practices for Hybrid Cloud Networking

A well-architected hybrid network is secure, scalable, observable, and resilient. Here’s how to build one that works:

1. Design for High Availability and Redundancy

🔁 Use Redundant Links and Routers at Both Ends
 🌍 Deploy Across Multiple AZs or Regions Where Possible
 🧠 Route Failovers Automatically via BGP or Cloud Load Balancers

2. Use Dedicated Connectivity for Mission-Critical Apps

🚄 Leverage Direct Connect (AWS), ExpressRoute (Azure), or Cloud Interconnect (GCP)
 🔒 Get Low Latency and Secure, Private Traffic Flow
 📈 Support High Throughput and SLA-Backed Uptime

3. Implement Robust IP Addressing and Routing Strategy

📘 Use Non-Overlapping IP Address Ranges Across Environments
 🧭 Plan Subnets With Growth and VPC Peering in Mind
 📶 Use Route Tables, NVA (Network Virtual Appliances), or SD-WANs for Advanced Routing

4. Secure All Traffic Between Environments

🔐 Encrypt Traffic With IPSec or TLS Over Public/Shared Links
 🛑 Apply Strict Firewall Rules, NSGs, and ACLs
 🧍 Enforce Identity-Aware Routing Where Applicable

5. Use a Centralized DNS Strategy

🧭 Leverage AWS Route 53, Azure Private DNS, or Infoblox
 📡 Ensure Consistent Naming Across On-Prem and Cloud
 🔁 Support Split-Horizon DNS When Required

6. Enable Unified Monitoring and Observability

📈 Use Tools Like Prometheus, Datadog, CloudWatch, Azure Monitor
 🛠️ Correlate Metrics Across Sites, VPCs, and On-Prem Devices
 🔍 Monitor Traffic, Latency, DNS Resolution, and Tunnel Health

7. Plan for Latency and Bandwidth Constraints

📊 Place Data and Apps Close to Users
 📦 Use Caching, Compression, and CDN Acceleration Where Needed
 🧮 Model Traffic Loads Across Links

8. Automate Configuration and Management

🛠️ Use IaC Tools Like Terraform, Pulumi, Ansible for Network Setup
 📋 Version-Control Network Changes
 ⚙️ Integrate Into CI/CD Workflows

9. Segment and Isolate Network Traffic

🚧 Use VLANs, Subnets, or SDN to Separate Environments
 🔌 Limit East–West Traffic Between Zones Unless Required
 🧱 Implement Zero Trust Architecture at the Network Layer

10. Ensure Compliance and Audit Readiness

📄 Log All Network Events (Flow Logs, Packet Captures)
 🧾 Monitor for Unauthorized Connections or Configuration Drift
 🧑‍⚖️ Support Regulatory Standards (HIPAA, PCI DSS, ISO 27001)

💡 Bonus Tip by Uplatz

The hybrid cloud isn’t a backup plan — it’s a strategic advantage.
 Build it like a first-class system, not a workaround.
