Designing private network connectivity between AWS and Microsoft Azure
Microsoft Workloads on AWS Blog
This article discusses strategies for designing private network connectivity between Amazon Web Services (AWS) and Microsoft Azure. It covers three main patterns:
- AWS Site-to-Site VPN over the public internet, with benefits like encryption and up to 1.25Gbps bandwidth, but limitations like relying on public internet and potential compliance issues.
- AWS Direct Connect and Azure ExpressRoute in customer-managed infrastructure, with benefits like private connectivity, predictable latency, and up to 100Gbps bandwidth, but requiring management of routing configurations.
- AWS Direct Connect and Azure ExpressRoute hosted by a multicloud connectivity provider, with similar benefits to the second pattern, but with routing managed by the provider.
For each pattern, the article provides architectural diagrams and discusses multi-VPC and single-VPC approaches. It also covers prerequisites, benefits, limitations, and key components involved in setting up the connectivity.
