- Now let's talk about regions.
Within AWS we have a number of different regions
all over the world,
and regions are sort of the primary building block of AWS.
It's the first thing that we start with.
It's the first decision that we make.
Before we start launching EC2 instances or storage volumes
or whatever else, we first have to decide
which region will these go into.
From which region will we run our applications
and serve our audience?
And so let's take a look at the regions
that are currently available.
If we look here on the map
starting from the West Coast of the U.S.,
we have the Oregon region,
the California region.
Those are U.S. West one and two.
We also have GovCloud West.
Moving towards the East Coast,
we have U.S. East two in Ohio,
U.S. East one in northern Virginia.
We have Canada Central up in Montreal.
Down into South America, we have Sao Paulo.
Moving into Europe, we have Ireland,
London, Paris,
Frankfurt, Germany,
and then moving farther east into Asia Pacific,
we have Mumbai, Singapore,
Sydney, Australia,
Ningxia, China,
Beijing, China,
Seoul, South Korea,
and Tokyo, Japan.
Now these 18 regions are currently available for use,
but there are a few more regions that are on the way.
As of the time of this video, these regions
are not yet online but they will be soon.
We have GovCloud East on the East Coast of the U.S.
We have Sweden, Bahrain, they're in the Middle East,
and then Hong Kong.
Right, so at some point here in the near future
if not already by the time of this video,
we will have 22 regions available
to run our applications and workloads.
So a common question is, well why do I choose
one region over another?
And it mainly comes down to several key things.
One many be due to cost, right?
Different services
cost different amounts in different regions.
So, the other reason might be
that you want to serve that application
to a particular audience,
and you want that application to run close to that audience
so that you can deliver the lowest latency.
If you don't have an audience that you're worried about,
if you're not really worried about latency,
then you may look at it
from a purely cost savings perspective.
Another reason we might choose one region
is because we need to consider data sovereignty
and laws and compliance around data sovereignty.
Certain countries in certain regions like the EU for example
have certain laws regarding
certain types of data
whether it can leave that particular geographic region
or not, so you may choose a region
that satisfies security and compliance, right?
So those are the regions that are available,
and those are some of the reasons why we might choose
one region over another.
