Azure's core services map closely to AWS equivalents, but with different terminology, pricing models and management approaches. A cloud engineer moving between the two clouds needs to know the equivalent services to translate architectural patterns without reinventing them. Azure Virtual Networks replace AWS VPCs; Azure Virtual Machines replace EC2; Azure Blob Storage replaces S3; Azure Kubernetes Service replaces EKS; and Azure Functions replaces Lambda. Understanding the key differences — such as Azure's Network Security Groups being attached to subnets and NICs rather than instances, Azure VMs requiring a public IP object, and Azure Blob's hierarchical container model — prevents frustrating debugging sessions when familiar AWS patterns produce unexpected results on Azure.

🏏 Think of it like cricket: The match itself is the kernel — real computation at the hardware level. The commentators translating that action into words for the audience are the shell: they take raw events and present them in a form humans can understand and interact with. The television set in your living room is the terminal emulator: it displays the commentary but does not participate in the match.Just as switching from one broadcaster to another changes commentary style but not the underlying match, switching between Linux distributions changes shell defaults and package manager but not the kernel. Just as Star Sports and Sony Six both cover the same IPL match with different graphics packages, Ubuntu and Alpine both run the same kernel with different userspace tools.The insight is that these layers are genuinely separate, which is why you can swap any one of them independently.
