>> What's up, everybody, Welcome back.
00:00
In this lecture we're going to be talking
00:00
about Network Watcher.
00:00
The learning objectives are
00:00
really just going to be to introduce
00:00
what Network Watcher is to make you aware of it,
00:00
then we're going to dive in to
00:00
some use cases and how it's useful.
00:00
Network Watcher, what is it?
00:00
It is essentially a monitoring and diagnosis tool.
00:00
It allows you to view metrics and
00:00
enable and disable logs for
00:00
the resources that are going to be stored
00:00
or managed in house within your virtual network.
00:00
This is your Azure virtual network, just to be clear.
00:00
Is something that is actually really cool,
00:00
because it gives you
00:00
full visibility on the various resources,
00:00
their relationships with one another,
00:00
it helps you diagnose for
00:00
>> issues like failing resources,
00:00
>> so you can identify when the health goes bad,
00:00
and then you can rest and up
00:00
those resources like virtual machines.
00:00
Overall, something that's really, really handy,
00:00
and I think that you should absolutely be aware of it.
00:00
Here is an example of a diagram
00:00
that can be produced with
00:00
>> Network Watcher. That's right.
00:00
>> You can get an idea of
00:00
the topology of your VNets and their relationships,
00:00
which is super handy.
00:00
I am a visual person,
00:00
my role as a security engineer,
00:00
a lot of what I do deals with threat modeling,
00:00
which is understanding the security concerns,
00:00
availability concerns that we have with infrastructure,
00:00
and when I see topologies,
00:00
it does help me understand the relationship,
00:00
and I can leverage that as a point of
00:00
reference for my threat modeling.
00:00
Something that I do encourage
00:00
other teams and other members
00:00
too if you aren't familiar with remodeling,
00:00
go ahead and Google it,
00:00
or you can reach out to me, and I'll be happy to
00:00
provide you with a bunch of resources.
00:00
But aside from that, Network Watcher is a great tool,
00:00
and it's something that is actually free.
00:00
It comes with VNets.
00:00
I shouldn't say free,
00:00
it is something [LAUGHTER] that you're
00:00
getting with what you're paying for within VNet.
00:00
It's not a separate service necessarily,
00:00
but it comes with the bundle there.
00:00
It's something that should heavily be utilized,
00:00
especially for those architects and administrator.
00:00
If you're going for the certification,
00:00
you likely are,
00:00
some systems engineer or administrator,
00:00
and you definitely do want to
00:00
leverage the logs and the metrics to help
00:00
you better improve your job and build
00:00
for efficiency and availability.
00:00
Like I said earlier,
00:00
it is something that is auto
00:00
deployed when VNets are configured,
00:00
so it's not something that
00:00
>> you're going to be adding on,
00:00
>> like an additional service,
00:00
it's just one that goes into the VNets environments,
00:00
and that you can just leverage right there.
00:00
I think one thing that's always important for us,
00:00
Ops guys, is just
00:00
making sure that we're building for performance.
00:00
One thing I get kicked back all the time
00:00
is whenever I want to deploy
00:00
an agent on a virtual machine or something like that,
00:00
there's always the concern that the agent is
00:00
going to cause more harm than it does good.
00:00
Agents, obviously they ingest and they share
00:00
that log and metric data maybe to a SEM or some type
00:00
of aggregate collection service to help us get
00:00
a full single pane of glass perspective on what's
00:00
going on with the virtual machines
00:00
in the network components.
00:00
Sometimes that can cause
00:00
performance issues on the
00:00
>> actual virtual machine itself,
00:00
>> so IT Ops will kick back and say,
00:00
hey, that's not right, we don't like that.
00:00
The cool thing about Network
00:00
Watcher is that it doesn't do that.
00:00
I say all that to say
00:00
that Network Watcher is not going to
00:00
impact your VNets, the routing,
00:00
the performance of the various resources within,
00:00
these services were already built for that in mind,
00:00
so you're not going to have to deal with any type
00:00
of lagging or performance issues whatsoever.
00:00
Overall, a really good service,
00:00
and I think that yes,
00:00
it is something that we will
00:00
include here in the network portion,
00:00
but it's obviously something
00:00
>> that deals with monitoring.
00:00
>> That is one of the domains for the AZ 104,
00:00
and you want to make sure that you keep that in
00:00
mind when preparing for your exam.
00:00
If you do happen
00:00
to find yourself preparing for that test and you want
00:00
to go ahead and test around with
00:00
the various services on
00:00
your own outside of our live environments,
00:00
I do recommend that you at least
00:00
play around with Network Watcher,
00:00
and get a good feel for what you can pull,
00:00
and what you can't pull within
00:00
>> your own lab environment.
00:00
>> To summarize this video up,
00:00
we introduced network watcher and what it is,
00:00
we talked about a few use cases
00:00
using Network Watcher and why you want to use it,
00:00
then obviously the deployment
00:00
and performance questions that
00:00
come to mind when we think
00:00
about building something like this up.
00:00
I hope this was helpful. I know it was short,
00:00
but it is something that it is very important,
00:00
and I do recommend you guys
00:00
do a little bit more reading up,
00:00
or at least go check it out
00:00
yourself in your own lab environments.
00:00
If you are using the labs within this course,
00:00
either there's a high likelihood
00:00
that you can actually take a look at that yourself,
00:00
so I do recommend you go ahead and see if you can,
00:00
but if it gives you any issues,
00:00
just feel free to open up your own Azure environments,
00:00
and spin up a VM,
00:00
and go ahead and see how
00:00
>> the Network Watcher tool works,
00:00
>> because it's pretty cool stuff.
00:00
All right guys, that wraps up this one,
00:00
I'll see you in the next lecture.
