Microsoft Azure Fundamentals - Describe the core architectural components of Azure Flashcards
This module explains the basic infrastructure components of Microsoft Azure. You'll learn about the physical infrastructure, how resources are managed, and have a chance to create an Azure resource.
What is Microsoft Azure?
Microsoft’s cloud computing platform.
Offers a wide range of services and supports IaaS, PaaS and Saas.
How many services does Azure provide
More than 100 services
What do you need in order to create and use Azure services?
An Azure subscription
What is included in an Azure free account?
- Free access to popular Azure products for 12 months.
- Credit to use for first 30 days
- Access to 25+ products that are permanently free.
What are the different ways to manage the Azure environment?
4 points
PowerShell CLI (command line interface)
BASH CLI
Azure CLI (Interactive mode)
Azure Portal (web interface)
What are the two main categories of Azure Core Architecture?
- Physical Infrastructure
- Management Infrastructure
What are Azure’s datacentres grouped into?
2 points
Azure Regions or Azure Availability Zones
What is an Azure Region
Geographical area containing one of more datacenters, networked together on low-latency network.
You can choose the region you want your resource deployed.
What is an Azure availability zone?
Physically separate datacenters within an Azure region. Set up to be an isolation boundary - if one zone goes down, the other continues to work.
How are Azure availability zones connected?
Through high-speed, private fibre-optic networks
What services are Azure availability zones primarily for?
- VMs
- Managed disks
- Load balancers
- SQL databases
What are the 3 Azure service categories that support availability zones?
- Zonal services
- Zone-redundant services
- Non-regional services
What happends with a Zonal Service
Resource is pinned to specific zone.
(for example, VMs, managed disks, IP addresses).
What happens with zone-redundant services?
The platform replicates automatically across zones (for example, zone-redundant storage, SQL Database).
Non-regional services
Services are always available from Azure geographies and are resilient to zone-wide outages as well as region-wide outages.
What are Azure Region Pairs?
Most Azure regions are paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away.
This approach allows for the replication of resources across a geography that helps reduce the likelihood of interruptions because of events such as natural disasters, civil unrest, power outages, or physical network outages.
Sovereign Regions
Sovereign regions are instances of Azure that are isolated from the main instance of Azure. You may need to use a sovereign region for compliance or legal purposes.
What is a resource?
Basic building block of Azure. Anything you create, provision, deploy, etc. is a resource. Virtual Machines (VMs), virtual networks, databases, cognitive services, etc. are all considered resources within Azure.
How many management groups can be supported by a single directory?
10,000
How many levels of depth can be supported by a management tree?
6
This limit doesn’t include the root level or the subscription level.
What does Azure RBAC stand for?
Azure role-based access control
