PaaS

Platform as a Service → The cloud provider manages the infrastructure and operating system; you mainly manage your applications and data.

SaaS

Azure Arc

helps you manage resources across different environments from Azure. This can include Azure, your own datacenter, private cloud, or other cloud providers.

VMware

technology used to create and run virtual machines on physical servers.

Azure VMware Solution

allows a company to run its existing VMware workloads in Azure, making it easier to move to the cloud.

VMware is technology that allows you to run multiple virtual computers (VMs) on one physical server, where each virtual computer works like a separate computer.

Consumption-based model

Pay only for the IT resources you use, making cloud computing an OpEx (operational expenditure) expense rather than an upfront CapEx (capital expenditure) investment, while allowing you to scale out (add resources) when demand increases and scale in (remove resources) when demand decreases.
