Hybrid Cloud Network Skills Detail Page

Skill Overview

Configure secure, high-performance network connectivity between on-premises data centers and cloud platforms (AWS, Azure, GCP), including VPNs, dedicated lines, and cross-cloud interconnection solutions.

Use Cases

Migrate to Cloud from a Data Center – Enterprises need to gradually move on-premises data centers to the cloud, or maintain network connectivity between on-premises and the cloud during the migration period.

Hybrid Cloud Architecture Deployment – Applications are deployed both on-premises and in the cloud, requiring stable network connectivity for data synchronization and load distribution.

Multi-Cloud Network Interconnection – When deploying services across multiple cloud platforms, you need to connect the networks between the clouds and the on-premises environment.

Core Features

Configuration for Major Cloud Platforms – Provides end-to-end configuration options for AWS Direct Connect/VPN, Azure ExpressRoute/VPN, and GCP Cloud Interconnect/VPN, including Terraform templates and BGP routing settings.

Hybrid Network Architecture Design – Offers common architecture patterns such as Hub-and-Spoke, multi-region hybrid, and multi-cloud hybrid; supports highly available dual-tunnel configurations and ECMP routing.

Security and Monitoring Best Practices – Covers encrypted transport, network ACL configuration, traffic monitoring, troubleshooting, and cost-optimization strategies.

Frequently Asked Questions

What is the Hybrid Cloud Network skill? Who is it for?

This skill is designed for operations engineers and network architects. It helps you plan and implement network connectivity between your on-premises data center and cloud platforms. Whether you are planning a cloud migration, building a hybrid cloud architecture, or need to set up cross-cloud networking, this skill provides complete guidance—from selecting the approach (VPN vs. dedicated line) to hands-on implementation.

What’s the difference between VPN and a cloud dedicated line? How should I choose?

A VPN establishes an encrypted tunnel over the public internet. It’s typically lower cost but bandwidth is limited (usually 1–3 Gbps), and latency is affected by the public network. Cloud dedicated lines (Direct Connect/ExpressRoute) provide physically isolated dedicated connectivity with higher bandwidth (up to 100 Gbps) and lower, more stable latency, but at a higher cost. A common recommendation is: use VPN for low-bandwidth or testing environments, and use dedicated lines for high-bandwidth production environments; highly available designs often combine both.

What can this skill help me do?

It can help you:

Configure AWS Site-to-Site VPN or Direct Connect

Set up Azure ExpressRoute or VPN gateways

Plan multi-cloud network architectures

Configure BGP dynamic routing

Achieve network high availability (dual tunnels, multiple paths)

Troubleshoot hybrid cloud network issues

Optimize hybrid cloud networking costs

It includes ready-made Terraform configuration templates, architecture diagrams, and troubleshooting commands, greatly improving implementation efficiency.

Is hybrid cloud networking secure? How do you ensure data transmission security?

Security is ensured through:

Using IPSec encryption for VPN

Dedicated lines provide physical isolation and do not traverse the public internet

Configuring network ACLs and security groups to restrict access

Using VPC PrivateLink/Private Endpoint to prevent data exposure to the public internet

Enabling traffic log monitoring to detect abnormal behavior

Performing security audits regularly

Which cloud platforms are supported?

Currently, it covers the three major cloud platforms: AWS, Azure, and Google Cloud, including their dedicated line and VPN services: AWS Direct Connect/Site-to-Site VPN, Azure ExpressRoute/VPN Gateway, and GCP Cloud Interconnect/Cloud VPN.
