Weekly Azure Roundup: Faster Networking, Resilient Messaging
Azure networking gains 400 Gbps ExpressRoute and improved VPN Gateway throughput, while Azure Service Bus Premium adds geo-replication GA. BizTalk Server end-of-support (2030) prompts migration guidance to Logic Apps.
Azure Networking, Resiliency, and Security Enhancements
This week’s networking improvements include 400 Gbps ExpressRoute options for high-demand workloads, increased VPN Gateway throughput, larger Virtual WAN and Route Server scaling, new forced tunneling and DNS Security rules, and automated failover scoring through ExpressRoute Resiliency Insights. A Copilot-based chatbot helps with networking troubleshooting. Updates to Azure Front Door clarify new deployment procedures (configuration validation, rapid rollback, edge resilience validation) and future enhancement plans around safety and isolation. Note also the upcoming deprecation of Docker Content Trust for Azure Container Registry, with planned migration to the Notary Project.

Migration, Modernization, and Strategic Guidance
Support for BizTalk Server ends in 2030; teams should migrate to Logic Apps and Integration Services. Existing mainframe connections remain supported through Host Integration Server, and tooling is available to help with these transitions. Guidance for Oracle Database@Azure addresses deeper integrations and AI enablement, while Storage Account replication changes (LRS to GZRS) require planned downtime—see official resources for planning.

Messaging Patterns, Data Engineering, and Microsoft Fabric Features
Azure Service Bus Premium supports active geo-replication for improved continuity. Developers benefit from workflow patterns—sessions, scheduling, retries, and dead-letter handling—for robust agent backends. SQL Telemetry on Microsoft Fabric highlights new analytics options, with autoscaling, data quality tools, and real-time analytics. Fabric adds support for DATE_BUCKET() and Eventstream SQL operator, providing improved time-series and event-based workflows.
