Since we recently migrated our blog to the Microsoft Tech Community platform, we think a brief introduction is in order. For starters, let's tackle what AzureCAT is. AzureCAT is a Customer Advisory Team that runs customer engagements and acts as feedback advisors to our product teams, based on what we learned from building ground-breaking Azure solutions with customers! Then we share the unique insights we learned with you by demonstrating lessons learned, architectures, best practices, and emerging patterns. You can always click the AzureCAT logo to get to the blog home page. Go ahead, try it.
What we learn makes it's way onto this blog (and other portions of our site) in a number ways, including whitepapers, e-books, analyst reports, customer stories, how-to blog posts, Microsoft Docs, the Azure Architecture Center (which highlights reference architectures and architectural guidance), and other resources. We've also created several pages that provide an aggregated look at all of our content for a specific concept:
- Mainframe Migration - Portal
- Hybrid Cloud Architecture - Portal
- HPC - Portal
- Datacenter Migration - Portal
- CATpapers - Our whitepapers
- Technical Customer Stories
If you want a deeper look at all of our content, you can visit the updated original post from the MSDN blog days. Check out our guidance and let us know what you think!
