This week, I stumbled into an interesting puzzle while investigating an issue for a client. They had recently transitioned from System A to System B, and one of their critical metrics suddenly showed significant discrepancies. Business-wise, these numbers were expected to remain identical, so naturally, it called for some digging. I started by checking the basics: Source API: Was the new system feeding incorrect data? No issues there. Transformed Reporting Tables: Were calculations or transformations misconfigured? Again, everything seemed correct. ...

I recently obtained the AZ-104 Microsoft Certified: Azure Administrator Associate certification. This is my second Azure certification after the Data Engineer Associate from last year. I am delibaretly focusing on the Azure platform as I believe deep knowledge on one cloud provider is more beneficial compared to shallow knowledge across multiple providers.

Therefore I wanted to take a quick note and reflect on the resources I used and methods I tried to follow. ...

Azure DNS is Microsoft’s hosting service for DNS domains. It allows users to manage their infrastructure and related related domain information in one central place. This alone could be a decent argument for Azure DNS. But one of the key benefits is the tight integration with Azure’s resources: Azure DNS aliases provide dynamic references to Azure resources and can be created at the zone apex level.

Hot This tier is optimized for frequent read or writes. It is thus suited for actively used data. It incurs the highest storage cost, but lowest access cost and is the default option when creating storage accounts. ...
