Azure Content Spotlight – ASOS: How they migrated from local monolith to microservices in Azure
In a series on Microsoft Mechanics called "How we built it", the lead architect from the British online fashion retailer ASOS describes the design goals and motivation for moving from an on-premises monolith to a multi-datacentre Azure global solution. Instead of duplicating the same solution in the cloud, the solution was rebuilt using microservices to improve scalability, reduce the brittleness of the solution under change and improve the development team efficiency.
The overall approach for decoupling the solution is summarized in ASOS: How they migrated from local monolith to microservices in Azure. Well worth the time viewing the 11 minute video.
