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.
