This blog (and several others) have been Azure hosted, on a monolithic SLES 15 virtual machine for a good few years.
I seem to have done the rounds on various flavours of Azure hosting. App Service with Project Nami, straight IaaS (like today), App Service with WordPress as a Microsoft provided service.
This last weekend I pulled the database out from the various blog VMs and moved that to a PaaS MySQL environment. It’s cheap, burstable, and seems more than performant for what I need. The other cool feature is VNET isolation – so the database engine is only accessible from my infrastructure running in Azure.
