Are you looking to learn about the Azure cloud and how it's organized? If so, this video
is for you. Hi, my name is Michael Gibbs, and I'm the
founder and CEO of go cloud careers. We're an organization that's dedicated towards building
the most high performance, cloud computing careers. Personally, I've been working in
technology now for over 25 years. And I've been helping others get their first tech job
or get promoted in tech for more than two decades. And I want to help you build your
best cloud computing career. Today, we're going to talk about the Azure cloud and how
it's organized. Most specifically, we'll be discussing our Azure regions, our Azure availability
zones, azure edge zones, add Azure points of presence. So begin with Azure regions and
Azure availability zones. An Azure region is a very large geographic area, think a continent,
or part of the continent. And think of an availability zone as a data center inside
of that large geographic region. So as you can see, in this graphic, we've got a blue
box, which refers to this big large geographic region. And on this big blue box, the region,
we have multiple buildings, each building represents a data center. And a data center
is referred to as an availability zone. Now these Azure data centers are going to look
and feel just like any other data center, they'll be filled with servers and storage
and firewalls and load balancers and routers, and switches just like any other data center.
And they'll be running the Azure cloud software on their traditional data center hardware.
Because the Azure Data Center is no different than anyone else's data center, it's just
running some special software to turn it into a cloud. Now let's discuss Azure edge zones.
See, Azure edge zones are relatively speaking an extension of an Azure region to put low
latency applications closer to the user. It enables businesses to have more computing
power with lower latency for critical high performance, low latency applications. So
let's talk about why this is necessary. So normally, speaking, in the traditional environment,
we have our data center. And the data center in most cases, is local to the campus where
the most critical functions are performed. And because all of the users, all of the user
information, all the applications and all the data are all so close to the user, there's
almost no latency. So if we need the highest performance of all kind, and the lowest latency
being in the data center is where it's at. But the cloud is so much more agile, it has
better scalability, there's a whole bunch of reasons to go to the cloud. And that's
what we love the cloud. So that's why we've migrated to the cloud. But the cloud is not
local to us. In many cases, the cloud could be 1000 miles away. So here's the challenge.
We have our data center, and we have the cloud to great services. But there's a cable between
these things, or a VPN or private Line Express connect direct connection, direct interconnect,
depending upon where you're on the AWS called the Azure cloud, the Google Cloud, it's all
multi cloud anyway, in today's world, but just understand that it could be 1000 miles,
and it could be million, it could be several milliseconds of latency between the data center
and the cloud provider. And under normal circumstances, that's fine. It's perfect. But for some critical,
low latency applications, it's too much. So the Azure edge zone is a midpoint. And you
can see in this graphic here, it's a midpoint between our data center in the Azure Cloud,
there's an edge zone, and in this edge, so we put our high performance, low latency computing
in this edge zone. And guess what, we have the high performance close to us, and we need
it. And we have all the great scalability of the cloud. And now you know about the Azure
edge zone. Now let's discuss the Azure points of presence. So the Azure Point of Presence
is the location of the Azure content delivery network. And Azure Point of Presence locations
are available in most major cities. And Azure Point of Presence locations, reduce the overhead
on your web servers, as your Point of Presence locations can also be used to increase the
security of your web applications by decreasing DDoS attacks as to all content delivery networks.
And of course, we'll have a chance to talk about that when we talk about security. But
going back to the Azure Point of Presence in most major cities, there's there and here's
what happens. The Point of Presence, traditionally speaking as a building where all of your Internet
Service Providers connect. So let's say we've got a giant building, we've got high speed
connections coming in from at&t, Ryzen, Telefonica, NTT, CenturyLink, Vodafone, you name it, all
our big internet service providers are all going to be in a single building. And what
happens is inside of this building, where all the internet service writers have high
speed connections to the building, they create connections between their switches. And the
reason this occurs when we do things on the internet, we go to our internet service provider
and if something we're looking for is on our end, Internet service provider, we're great,
we never leave our internet service provider. But let's say I want to go to a website that's
hosted by Verizon, and I'm in my house and my internet service providers, at&t, the way
Internet routing will occur is I will go go to my ISP, I will leave my ISP and go to Verizon,
and where that handoff between ISPs occur is with a point of presence. So the point
of presence locations are where we have our highest speed connections connecting our internet
service providers. So think about how smart this was for Azure to use these Point of Presence
locations, all your Internet Service Providers effectively earn a logical area and an appointed
presence, we're going to stick our caching servers in the Azure content delivery network.
Excellent, super smart. The Azure content delivery network will do wonders for improving
our performance, our security and our scalability. Now, let's walk you through the Azure Point
of Presence content delivery network in action. So here we've got a user, the users wearing
a blue shirt and an orange tie, the user wants to go to w w w.go, Cloud careers.com. So the
user enters WWW dot GovCloud careers.com on the browser, their computer does a DNS lookup
and says, Okay, here's the IP address for www.go, Cloud careers.com. So then the PC
goes to that IP address through the use of the networks. And the first location it's
going to go to is that point of presence or content delivery network pipe, and what happens,
the user is going to go to that point of presence. And it's going to see if that web page that
he or she requested was there. And if it's not there, they'll go back to the source.
So the user up top and the blue suit in the blue shirt will go to the Point of Presence
location, the Point of Presence location will look and say, Do you have it. And if it doesn't
go straight to Azure, where our virtual machines and our blob storage are hosting our our website,
all is great. That sends it back to the point of presence, and it sends it back to the user.
Now the next user that wants to go to the same website, www go cloud careers.com. Before
the cache times, though, we'll go to that same Azure Point of Presence location, and
guess what it will be there from the first user, and the webpage will be immediately
sent to the user. So faster, because it's cached uses less data and less web server
time because the web servers aren't even responding to anything other than the first request.
So that's the Azure appointed presence location. And that's how content delivery networks work.
So what did we discuss today, we discussed Azure regions, we discussed Azure availability
zones, we discussed our Azure Edge locations, and we discussed as your points of presence.
