AZ 900 Glossary Questions and Answers
account - answer An account that's used to access and manage an Azure
subscription. It's often referred to as an Azure account although an account can be any
of these: an existing work, school, or personal Microsoft account, or an Office 365 user
name and password.
API app - answer Another name for App Service app.
App Service app - answer The compute resources that Azure App Service provides
for hosting a website or web application, web API, or mobile app backend. App Service
apps are also referred to as App Services, web apps, API apps, and mobile apps.
availability set - answer A collection of virtual machines that are managed together to
provide application redundancy and reliability. This ensures that during either a planned
or unplanned maintenance event at least one virtual machine is available. See Manage
the availability of Windows virtual machines and Manage the availability of Linux virtual
machines
Azure classic deployment model - answer One of two deployment models used to
deploy resources in Azure (the new model is Azure Resource Manager). Some Azure
services support only the Resource Manager deployment model, some support only the
classic deployment model, and some support both. The documentation for each Azure
service specifies which model(s) they support.
Azure command-line interface (CLI) - answer A command-line interface that can be
used to manage Azure services from Windows, macOS, and Linux. Some services or
service features can be managed only via PowerShell or the CLI. See Azure CLI
Azure PowerShell - answer A command-line interface to manage Azure services via
a command line from Windows PCs. Some services or service features can be
managed only via PowerShell or the CLI. See How to install and configure Azure
PowerShell
Azure Resource Manager deployment model - answer One of two deployment
models used to deploy resources in Microsoft Azure (the other is the classic deployment
model). Some Azure services support only the Resource Manager deployment model,
some support only the classic deployment model, and some support both. The
documentation for each Azure service specifies which model(s) they support.
fault domain - answer The collection of virtual machines in an availability set that can
possibly fail at the same time. An example is a group of machines in a rack that share a
common power source and network switch. In Azure, the virtual machines in an
availability set are automatically separated across multiple fault domains.
, geo - answer A defined boundary for data residency that typically contains two or
more regions. The boundaries may be within or beyond national borders and are
influenced by tax regulation. Every geo has at least one region. Examples of geos are
Asia Pacific and Japan. Also called geography. See Azure Regions
geo-replication - answer The process of automatically replicating content such as
blobs, tables, and queues within a regional pair.
image - answer A file that contains the operating system and application
configuration that can be used to create any number of virtual machines. In Azure there
are two types of images: VM image and OS image. A VM image includes an operating
system and all disks attached to a virtual machine when the image is created. An OS
image contains only a generalized operating system with no data disk configurations.
limits - answer The number of resources that can be created or the performance
benchmark that can be achieved. Limits are typically associated with subscriptions,
services, and offerings. See Azure subscription and service limits, quotas, and
constraints
load balancer - answer A resource that distributes incoming traffic among computers
in a network. In Azure, a load balancer distributes traffic to virtual machines defined in a
load-balancer set. A load balancer can be internet-facing, or it can be internal.
mobile app - answer Another name for App Service App.
offer - answer The pricing, credits, and related terms applicable to an Azure
subscription. See the Azure offer details page
portal - answer The secure web portal used to deploy and manage Azure services.
region - answer An area within a geo that does not cross national borders and
contains one or more datacenters. Pricing, regional services, and offer types are
exposed at the region level. A region is typically paired with another region, which can
be up to several hundred miles away. Regional pairs can be used as a mechanism for
disaster recovery and high availability scenarios. Also referred to as location.
resource - answer An item that is part of your Azure solution. Each Azure service
enables you to deploy different types of resources, such as databases or virtual
machines. See Azure Resource Manager overview
resource group - answer A container in Resource Manager that holds related
resources for an application. The resource group can include all of the resources for an
application, or only those resources that are logically grouped together. You can decide
how you want to allocate resources to resource groups based on what makes the most
sense for your organization. See Azure Resource Manager overview
