>> Welcome back to Microsoft Azure Fundamentals.
00:00
This is Module 3 of the course,
00:00
Azure Global Infrastructure and SLAs.
00:00
In this module, we'll discuss
00:00
Azure's global footprint and
00:00
the service guarantees it offers.
00:00
We'll start with an overview of Azure datacenters
00:00
around the world and
00:00
introduce some important terminology.
00:00
Then we'll talk about availability zones
00:00
and how those relate to the global Azure footprint.
00:00
After that, we will define what a service level agreement
00:00
is and talk about the SLAs for different Azure services.
00:00
At the end, we'll learn how the SLA for
00:00
our own applications are
00:00
impacted when using Cloud services,
00:00
as well as how to improve that.
00:00
Throughout this module, we'll introduce a lot of
00:00
new terminology that you're
00:00
going to need in your work with Azure.
00:00
Let's see how Azure is able to
00:00
provide its services around the world.
00:00
Here's a map of Azure's global footprint.
00:00
It's available on Azure's website
00:00
and you can check it regularly for updates.
00:00
Each blue dot on the map represents the so-called region.
00:00
A region is a geographical area with at least one,
00:00
but sometimes multiple datacenters.
00:00
Azure controls the resources within
00:00
the region to make sure
00:00
that they're appropriately balanced.
00:00
At the time of this recording,
00:00
Azure has 48 available regions
00:00
and six new ones they've announced.
00:00
Two of the regions are not
00:00
shown on the map because there are
00:00
secret US government regions
00:00
and are in undisclosed locations.
00:00
When you create a new resource in Azure,
00:00
you may be required to select a region.
00:00
Some services are available only in certain regions.
00:00
For example, not all virtual machine sizes
00:00
are available in every region.
00:00
GCDS VMs are available in West US 2,
00:00
West US and East US 2 regions,
00:00
but not in the other US regions.
00:00
There are also services that are global and
00:00
do not require you to select a specific region.
00:00
Some examples are Azure Active Directory,
00:00
Azure Traffic Manager, and Azure DNS.
00:00
One important thing to note is that there are
00:00
certain limits to the resources
00:00
that you can create within a region.
00:00
If you reach this limit,
00:00
you need to create a support ticket
00:00
to extend the limit or
00:00
create resources in another region
00:00
where you have not reached the limit.
00:00
Some regions are special though,
00:00
and you can use them for building
00:00
applications that need to
00:00
meet certain compliance or legal requirements.
00:00
You may also not be allowed to deploy to
00:00
those regions if you don't
00:00
meet those compliance requirements.
00:00
The US government and Department of Defense regions are
00:00
available for US government agencies and partners.
00:00
They're operated by personnel with
00:00
higher clearance and have additional certifications.
00:00
China's regions are offered in
00:00
partnership with a third party provider,
00:00
and Microsoft doesn't maintain the datacenters.
00:00
Germany's regions are available via a data trustee model.
00:00
Well, the data trustee is
00:00
a Deutsche Telekom Company called T-Systems.
00:00
This is the company that ensures
00:00
that the data remains within Germany.
00:00
Now, why does Azure need datacenters in so many regions?
00:00
Well, there are several reasons.
00:00
First, it allows you to bring your data
00:00
and application closer to your customers.
00:00
It also provides better scalability and redundancy.
00:00
Last but not least,
00:00
it preserves the data residency for your users
00:00
and helps you to stay compliant with local requirements.
00:00
Azure divides the world into four geographies.
00:00
The Americas, Europe,
00:00
Asia, Pacific, and the Middle East and Africa.
00:00
A geography is a discrete market with
00:00
two or more regions that
00:00
preserves residency and compliance boundaries.
00:00
Why is there yet another subdivision of the world?
00:00
Well, there are some legal and compliance reasons.
00:00
There are two main reasons for using geographies.
00:00
They ensure that data residency and
00:00
sovereignty requirements are honored within
00:00
the geographical boundaries and they are
00:00
fault tolerant to withstand complete region failure.
00:00
Speaking of data residency,
00:00
one typical example is GDPR,
00:00
which we talked about in the previous videos.
00:00
The law requires that
00:00
European citizens data is to remain on European soil.
00:00
Each Azure region belongs to a single geography and has
00:00
specific data residency compliance and
00:00
service availability rules applied to it.
00:00
Another important thing to know about regions is that
00:00
every region is paired with
00:00
another region in the same geography.
00:00
This is called a region pair.
00:00
Region pairs are helpful when you think about
00:00
business continuity and disaster recovery plans.
00:00
Region pairs are directly connected and
00:00
must be 300 miles away from each other.
00:00
This ensures that in the case of disaster,
00:00
your workloads will continue to
00:00
run even if one of the regions is down.
00:00
Some services offer
00:00
automatic geo redundant data application
00:00
using region pairs.
00:00
Additional advantages of region pairs are
00:00
that in the case of extensive Azure outage,
00:00
one of the regions is prioritized to reduce the downtime.
00:00
Also, planned updates are
00:00
rolled out to regions one at a time.
00:00
Additionally, data continues to reside
00:00
within the same geography if disaster occurs.
00:00
Some examples of region pairs are East US and West US,
00:00
North Europe in Ireland,
00:00
and West Europe in the Netherlands,
00:00
and East Asia and South Asia.
00:00
One exception to the rule is Brazil South,
00:00
that is paired with South Central US.
00:00
In the next video, we'll look at
00:00
what redundancy Azure provides within a single region.
