Azure DevOps ExpressRoute Connectivity

2 posts · Oct 2017 – Oct 2018

What this trail covers

Azure DevOps is now available over Azure ExpressRoute, enabling private, reliable, and faster connections for customers in sectors like government and financial services. This connectivity is achieved through Microsoft peering and route filters, specifically the 'Azure Global Services' route filter (BGP community 12076:5050). This applies to various Azure DevOps services, including the dev.azure.com URL, visualstudio.com URLs, self-hosted agents, and the Visual Studio Marketplace/Subscriber port. This post details the migration of VSTS SSH to Azure's global network, leveraging Azure Traffic Manager to route requests to edge nodes for reduced latency, and the subsequent requirement for users to update their SSH remote URLs.

All Microsoft trails
  1. ExpressRoute for Azure DevOpsThis post announces the availability of Azure DevOps over Azure ExpressRoute. It details how customers can leverage ExpressRoute for private, reliable, and faster connections by configuring Microsoft peering and route filters. The 'Azure Global Services' route filter with BGP community 12076:5050 is specified for Azure DevOps. The post lists all supported Azure DevOps services and explicitly excludes static content delivered via Azure CDN. It also mentions the requirement to configure regional route filters for Azure Artifacts.
  2. VSTS SSH on Azure's Global NetworkThis post explains the motivation and technical details behind moving Visual Studio Team Services (VSTS) SSH to Azure's global network. It describes the current model where SSH requests are routed directly to the datacenter, leading to potential latency issues. The new model utilizes Microsoft's global network with edge nodes and Azure Traffic Manager to route requests more efficiently, requiring a new domain and SSH URLs. Performance improvements are expected, with anecdotal evidence of a 5x increase in transfer speed for HTTPS traffic. Users are instructed to update their SSH remotes by December 1, 2017.
