Describe the core architectural components of Azure Flashcards
It is a geographical area on the planet that contains at least one but potentially multiple datacenters that are nearby and networked together with a low-latency network.
Azure region
True or false.
When deploying a resource in Azure, you’ll often need to choose the region where you want your resource deployed.
TRUE
Name a few examples of Azure regions
West US Canada Central West Europe Australia East Japan West.
What are some special Azure regions in the US?
US DoD Central
US Gov Virginia
US Gov Iowa
These regions are available through a unique partnership between Microsoft and 21Vianet, whereby Microsoft doesn’t directly maintain the datacenters.
China East
China North
Define special Azure regions
These are regions that you might want to use when you build out your applications for compliance or legal purposes.
What is an availability zone?
Availability zones are physically separate datacenters within an Azure region.
How are availability zones connected?
Through high-speed, private fiber-optic networks.
Why is it said that an availability zone is set up to be an isolation boundary?
If one zone goes down, the other continues working.
True or False
Every region has support for availability zones.
FALSE
Is it cheaper to use availability zones?
NO
There could be a cost to duplicating your services and transferring data between zones.
What are availability zones mainly used for?
VMs
Managed disks
Load balancers
SQL databases.
…is a unique physical building that contains thousands of physical servers with it’s own power, cooling and networking infrastructure.
Azure data center
These Azure services don’t require you to select a particular region.
Azure Active Directory
Azure Traffic Manager
Azure DNS
Why are regions important?
Global regions provide better scalability and redundancy.
They preserve data residency for your services
Azure regions
TRUE / FALSE
There must be a minimum of 3 availability zones within a single region
TRUE
What is a region pair?
Each Azure region is always paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away.
Interruptions because of events such as natural disasters, civil unrest, power outages, or physical network outages can be reduced by:
Azure region pairing
TRUE / FALSE
Regarding region pairs:
Data continues to reside within the same geography as its pair (except for Brazil South) for tax- and law-enforcement jurisdiction purposes.
TRUE
What is the main advantage of having a broadly distributed set of datacenters?
High guarantee of availability!
A manageable item that’s available through Azure. Virtual machines (VMs), storage accounts, web apps, databases, and virtual networks are examples of it.
Resource
A container that holds related resources for an Azure solution.
Resource group.
It is a logical container for resources deployed on Azure.
Resource group
TRUE / FALSE
All resources must be in a resource group.
TRUE
TRUE / FALSE
A resource can only be a member of a single resource group.
TRUE
TRUE / FALSE
Resource groups can be nested
FALSE
