ABCS25: True Tales of Cloud Modernisation: From Legacy to Serverless by Adrian Pritchard

⭐️ True Tales of Cloud Modernisation: From Legacy to Serverless#
A story of how I helped migrate legacy solutions that were built on Microsoft BizTalk Server 2010 and Dynamics CRM 2011 to modern Cloud technologies, such as Azure Functions, Azure Application Insights, Azure SQL, and Dynamics 365. Join me to learn about the interesting set of challenges, trade-offs, and constraints that I faced, the solutions that I designed, and I code that I wrote, on the journey to a truly cloud-native architecture.
