>> Running in over 60 metro areas around
the world on Microsoft's global edge network,
as your Front Door Service is
a highly available and scalable
web application acceleration platform.
Sharad Agrawal is here to show us how the Front Door
enables you to make your global applications faster,
highly available and scalable.
Today on Azure Friday.
Today on Azure Friday,
we're going to learn all about Azure Front Door Service.
With me is Sharad Agrawal who is APM for Azure Front Door.
Talk to us about what we're going to
learn about today with that Front Door.
>> So, Front Door is of
global web application acceleration platform and
it helps you make your service really scalable,
make it much much more available,
it increases your applications reliability
and all of this
while giving you a lot of performance boost.
We also take care of security application layer security.
So, I'm going to talk about it in a while. Thank you.
>> Okay.
>> Yes.
>> Okay. Why don't you walk us through what this is.
>> Sure. Okay. So, in a typical case what happens,
how do you really connect with your application
to your users to your application backends.
If you're not using a contain delivery network
on an application delivery network, what happens is that,
your users travel from their location to
your regional deployments and
then that all that happens or
would the long open internet,
which is not reliable,
somebody some ISP in the middle can play around with
your routing announcements and things like
that and you get a lot of network errors.
It's not really [inaudible].
So, what happens is when
you introduce a continuity network
or an application deliver network.
So, the BOPs are the points of presences for
these CDNs or these application delivery networks,
they help you connect
the end-user connection very close to them.
Then they maintain long haul connections
to your application back in.
So, you're able to connect make
those SSL handshake very close to
your end-users and then correspondingly from there to
the backend again because these are all
warm connections getting deals,
you get the performance boosted as well.
You might feel like there's hope getting out,
but it still gives you performance benefit overall.
So, what does Azure Front Door
Service brings to the people.
Well, we use our global network,
it's a dedicated private network of Microsoft.
We are actually very
proud and boasted about it quite a lot.
So, from the age bop to
the your application back and it goes
over Microsoft global network.
So, there is much much more
higher network reliability that you get.
Even if your application is not hosted on Azure,
we still route it to
the nearest point where the application is
and then exit from that location.
So, you sort of get a dedicated network for
your end users and so it just boosts
your network performance and your reliability.
>> Okay.
>> Okay. So, what more about Azure Front Door?
So, Azure Front Door or is,
let me begin with the last portion which is,
you've been there for quite a good amount of time.
We've been there internally for over five years
now and we've been dealing with some
of the biggest Microsoft's web workloads.
>> So this is nothing new.
We've been doing this with our own-
>> Yes. Absolutely.
>> -properties for our services.
How can you say five years or more.
>> Yes.
>> So, we started with Bing
to be honest and then we slowly
added these different workloads both on
the consumer side on the enterprise applications side.
So, all these are in fact
right now running on Azure Front Door.
It's just that we're not exposing
this capability commercially.
>> Right, and so now any customer can come along and
take advantage of this as a service.
>> Right. Absolutely.
>> Okay.
>> Yes.
>> Would there be any kind of scale limit?
I mean what is the scale capability of a service.
>> So, as I explained the kind of applications
you see at the bottom of the logos that we put.
These ran into for your IDs I guess running
multi-million requests per second globally.
So, there's not a limit that you found
as such or we can do
massive SSL offloads for applications
and people have been asking me how much is a SSL offload?
Or is there a limit to it?
I wouldn't say there's a limit to it.
I mean not that we have found very easily thus far.
So, we provide
application acceleration from Microsoft's edge.
We have built a very seamless experience
integrating with app services,
with cloud services, that storage
will be continuously adding more to such integrations.
We are global GDP load balancing.
So, we only do HHTP workloads
and then we provide instant multi region or global [inaudible] .
So, if your application since it's running,
I will actually show a demo on that,
if they're running into regions,
iif one of them goes down, we'll feel work as
soon as we detect that particular instance has gone down.
>> What if I wanted to play this to
specific areas, specific geography?
>> That's a good question. So, Azure Front Door Service
is a global platform.
So, as soon as you create a Front Door instance,
we deploy your configuration
across all of our BOPs globally.
So, you don't have to just do it, Okay.
I want to deploy just in
central US in particular regions in India.
It just gets applied to
all locations everywhere our BOPs are.
>> And on the other side what if I don't want it
deployed to certain areas or certain regions?
>> Yes. So, the question
that we get regarding that usually is okay.
I want to filter traffic for
particular user and it can go both ways,
people ask what I want to only allow traffic from users
of these countries or I want to
block traffic from xyz countries?
So, if we had the capability
to enable Geo-filtering you can
allow or block certain countries
for your traffic for your web uploads.
>> Great. Great.
>> Do you have something to show us.
>> Sure, sure absolutely.
>> Okay.
>> So, here are an instance,
so I'll just showcase what the creation workflow is.
So in this I'm just creating a particular resource group,
say shared test here, moving on.
So, what you need to do is
first provision up frontend hosts.
Basically, this is the up frontend Front Door
for your application with it,
let's call it Friday demo.
Okay. Then the next thing
you need to do is you need to add back and pool.
So, what you've done is,
there are three high level concepts
there's a frontend host then there are back and
pools and then you have routing tools that can take
these front and host to the backend pools.
So, let me name this, just test for now.
I quit and add backend pool.
Let me pick something that I already have.
Let me add another instance.
Let me pick another, okay.
Okay. So, I have added two backends here.
I'm just explaining all of this flow.
So, you can control how
the health probes its central function,
for your particular backend pool.
Where do we need to send the health probes.
How often do we need to send the health probes.
You can define, how many samples that you need for
the health probes to be evaluated,
and then how many you need for it to be successful.
>> Okay.
>> This zero is more
like send it to the fastest available backend.
>> Okay.
>> Yeah. We can increase to increase
the threshold your latency sensibly,
so that you can round robin
across multiple ones if you want to.
But, if you are very latency
sensitive to set it to zero to always pick
the fastest backend where you need to send the traffic
to. So, I'll add the backend.
I would just go ahead and create a routing rule.
So, it just automatically picks up the values.
It's just saying that for
this particular Frontend hosts
which is friday-demo.azurefd.net.
Anything underneath, just send it
to the backend pool that I just created.
It will automatically pick one of
the backend switcher up and running.
>> Okay.
>> The one which is also closest to you.
You can additionally also go and enable
other feature at once like caching.
You can do caching and stuff.
But for now, let me just go ahead and create it.
So, as you can see it's actually pretty
simple and straightforward to have it.
>> Yes. It just wax, you wait though it.
>> Yeah. It's very simple straightforward.
So, then to stop time what I'll do is I just
pick an existing instance that I've created.
So, I have two websites that I've created here.
So, one of them is in Central US.
This is the Azure website
and there's another one which
is North Europe that I've created.
>> Okay.
>> So, this is the one in Central US,
and this is the instance that I haven't North Europe.
What I'm going to do is now showcase what
Front Door is, how the Front Door is set up.
So, I've created AzfridayDemo.azurefd.net.
I have added both these instances, you see.
This is the Central US one and the other one
is for North Europe that I've added here,
and I can simply open
the routing rule that connects
them. So, it just connects it.
Okay. Anything coming AzfridayDemo.azurefd.net
goes to that particular backend pool as explain.
So, let me just refresh this.
So, you can see it's going to Central US.
What it's showing is, because I
was right now in Seattle area.
This is picking up the closes North Europe that
is there so it's automatically going to Central US,
it's not going to North Europe instance, for example.
>> Right.
>> At previous screen this all was from
a field of scenario that I have.
Now, let me do a quick test site-by-site.
Okay. So, what I'm trying to do here is
on the left hand side I'm trying to
go to Azure Front Door for instance,
and on the right hand side I'm
hitting the up services instance that you see.
You'll see that I'm actually going
to do a Central US instance here.
On the left side I'm actually going to the
azfriday.demo instance that I
just created for Azure Front Door.
What's also going is,
it's actually going and pulling a 100 kb object.
It's an image file. There is no caching whatsoever.
>> Okay.
>> So, it's just pulling it
every time it's creating a connection.
>> Okay. So, let me just start this.
I'm going it to give advantage to
app service hitting it directly,
and then I'm going to start the other one.
So, it's just creating
the object again and again and again.
You start to see the difference slowly picking up
as connections getting warmed up and getting to use.
>> Yeah. I can definitely see
some performance improvements going through Front Door.
>> Yeah.
So, we'll see how much like
you're getting and I'm not playing around.
In fact, to be
honest we are actually on
the Microsoft corporate network right now.
So that the proxies it's a trend
to also play a role in that,
but it becomes even
better in some other venue actually in the open Internet.
>> Right.
>> On normally end-user is trying out.
Okay. So now, let me go to
the next part of the demo here.
We talked about instant global fail worse scenario right.
>> Right.
>> So, what I'm going to do
is from my Central US instance,
I actually set the health probe to
test this file, test.html.
I can actually show that to you. So yeah.
So, this is still working and I'm going to just new it.
So that just a simple test will be done,
to fill the health probe will be.
I'll just rename the file and
cohered by the way this is a cool
feature that app services build.
I can make a line changes and
deploy just immediately in the place.
I check this in, as soon as I check this in,
app service instance will get automatically updated.
So, you can see the health probe started failing.
>> Right
>> Now, what is effectively happening right now,
is that we have set
some health probe frequency as I mentioned.
So, it is looking for those number of samples.
As soon as we have enough numbers
of samples to see that okay.
Now, the backend is done, I need to failover.
We will start failing over instantaneously
the moment we detect that happening.
We have enough samples attached.
So, here's my instance which
it will still go to Central US,
because I just fail the health probe.
The site is still up and running
that particular default site.
But, in a few seconds,
you will notice that it's actually start failing
or failing over to the North Europe instance.
Give it a few seconds. Yes.
>> There we go.
>> So, it'll constantly
keep going to the North Europe instance.
Okay.
So, that's the immediate
failover worse scenario that I was talking about.
>> Great. Now, it was pretty easy to setup,
so through easy setup you immediately
get some much higher performance.
>> Right.
>> Almost half the time.
>> Yeah.
>> You get failover and high availability,
more highly available application.
>> Yes. Even when the high availability is getting
showcase and there's an instant global failover,
because we're maintaining these
warm connections of the two.
Because there are multiple users that
actually connecting to Front Door.
All of this will happen.
Your failover will happened.
The minimum to low latency impact us.
We'll just be pulling it from
the North Europe instance in this particular case.
But, then because of Microsoft's global network
it could still be pretty pretty fast,
pretty much faster a lot faster than hitting it directly.
>> Fantastic. Well, thank you so much for
coming in and talking to us about Azure Front Door.
It's be great to see this go into public preview.
>> Yes.
>> Customers to be able to sign-up
and take advantage of this.
>> Yes.
>> So, It's already available in public preview starting.
>> So, it's going into public preview on Monday,
the 24th of September.
>> Okay
>> It will be launching at ignite for the first time.
So that you can actually go
to the link azure.com/frontdoor.
Read more about and your
will have an interested things
getting started from there.
>> Great. Thank you very much and I look
forward to learning more about
this and using the service.
>> Thanks so much Lara.
>> We've been learning all about
Azure Front Door today, on Azure Friday.
