Outlines
🌐 AWS Global Infrastructure Overview
This paragraph introduces the AWS global infrastructure, focusing on the concept of 'regions' which are physical locations that make up the AWS cloud platform. Regions are independent and geographically distant from each other. Within each region, there are 'availability zones', which are clusters of data centers. As of the recording, there are 26 regions, but this number is constantly changing as AWS expands. Regions are connected via a high-bandwidth, fully redundant network known as the AWS global network backbone. Each region contains at least two availability zones to provide redundancy. The paragraph also mentions 'local zones' which extend regions closer to end users to reduce latency. Latency is the delay over a network, and it increases with distance from the service. The infrastructure within a region includes multiple availability zones, each composed of one or more data centers with redundant power and networking for high availability. AWS Outposts allow running AWS services on-premises, and 'wavelength zones' enable low-latency connections to end users via 5G networks. Use cases for these components include on-premises AWS API access, single-digit millisecond latency for mobile devices, and reduced latency for end users.
📡 CloudFront Network and AWS Infrastructure Details
The second paragraph delves into the CloudFront network, which is a content delivery network (CDN) service that caches content like video files and images in 'edge locations' close to users worldwide. This reduces latency and improves performance by serving content from locations that are geographically closer to the users. The paragraph emphasizes that the number of edge locations and regional edge caches can change and that it's not necessary to memorize these numbers for the AWS exam. The focus is on understanding the concepts rather than exact figures. The paragraph concludes with a mention of the dynamic nature of AWS infrastructure, indicating that the numbers provided are subject to change and that the key takeaway is the global reach and performance optimization of AWS services.

[Music]
in this lesson i'm going to cover the
aws global infrastructure so what i'm
talking about is the infrastructure that
makes up the aws cloud platform around
the world
now the first concept to understand is a
region a region is a physical location
in the world and regions are independent
from each other and they're
geographically distant from each other
as well
within a region we then have
availability zones availability zones
are composed of one or more data centers
and you can essentially think of these
as a cluster of data centers now there
are lots of regions around the world as
of this recording there are 26 but i
added a plus there because that might
well have changed by the time you watch
this video aws are constantly expanding
and you don't need to let me know when
it's changed i know it's changing all
the time and you don't need to remember
these numbers for the exam so the aws
regions are connected via a high
bandwidth fully redundant network that's
the aws global network backbone
now each region will contain two or more
availability zones so that means that
you can deploy your resources across
availability zones and you get lots of
redundancy by doing that
there's also something called a local
zone which we'll go into in a bit more
detail shortly
local zones extend regions closer to
your end users really that's for
reducing latency latency is the delay
over a network typically the farther you
are from a specific service the more
latency there's going to be across that
network
so let's look inside of region in a bit
more detail
so within a region as i mentioned there
are two or more availability zones
within those availability zones you can
create your subnets they can be public
subnets or private subnets and each
subnet is always within an availability
zone and you can create many many
subnets availability zones are one or
more data centers each availability zone
is composed of one or more data centers
and each of those data centers will have
redundant power sources you also have
redundant networking within each of the
data centers so there's lots of
redundancy for power for cooling for
networking for all of the resources on
which the cloud services depend
so you can then deploy your resources
across subnets and availability zones
and you get lots of high availability
for your applications
so what other components are there so
let's say we have our region here with
some availability zones and we've
created our subnets
we might want to extend some of the
services into our on-premises data
center within our company so we can use
aws outposts to do exactly that
with outposts you can run some aws
services on dedicated hardware within
your own data center
and that means that you've got really
low latency access and you can develop
and build your applications within your
own on-premises data center
we also have local zones so local zones
help you to get aws services closer to
your end users
and that means you get lower latency so
less delay over the network because
they're closer than the region might be
to wherever you actually are or your
users actually are
we also have something called a
wavelength zone this is also about
getting your services to your end users
but in this case via a 5g network
so users can connect with low latency
over their 5g networking to services
that you're running in the wavelength
zone and those are all connected to your
aws region as well
so what are the use cases for aws
outposts
we would use it to get aws services
running in our on-premises data centers
and so that we can use aws apis on
premises
for wavelength zones this is about
getting single digit millisecond latency
to mobile devices and end users
it's good for live video use cases
machine learning augmented reality and
virtual reality and then lastly for
local zones we want to use these for
single digit millisecond latency to our
end users and applications and again for
similar use cases as the wavelength zone
another important part of the aws global
infrastructure is regional edge caches
and edge locations these are part of the
cloud front network cloud cloudfront is
a content delivery network services cdn
and essentially what we use these for
are to get content closer to our end
users for better performance
so for example we might cache video
files or images in the edge locations
that are close to our users around the
world and there are many edge locations
and regional edge caches so that means
the latency is lower and the users can
download or watch those videos without
having to go a long distance around the
world to get them
so that's the cloudfront network and of
course again these numbers are subject
to change
lastly i'll just show you the actual
numbers for the aws global
infrastructure today as i mentioned
these numbers change all the time so you
don't need to let me know when they
change i'm aware of that and it's not
important for the exam to know any exact
numbers for the number of regions or azs
you just need to understand the basic
concepts around these different parts of
the global infrastructure but it's good
to get an understanding of how many of
these there are around the world
