SPEAKER: As enterprises digitally transform themselves,
networks are at the foundation.
While networks are constantly modified
to support business applications,
you need a single pane of glass that
can address all aspects of troubleshooting and monitoring
so that complex connectivity and network performance
issues are easier to diagnose.
Network Intelligence Center is Google Cloud's framework
for network monitoring across the cloud and on premise.
It improves user experience, security, and operations
by providing a comprehensive platform for monitoring,
visualizing, and troubleshooting network health across the cloud
and data center.
Network Topology is a module in Network Intelligence Center
that helps you visualize your network so that you can monitor
your network health easily.
We have heard from customers that visualizing cloud
topologies is not trivial, as the cloud network is really
a mesh.
Everything talks to everything else.
Imagine 1,000 instances talking among themselves.
There is also a difference between an on prem and cloud
environment, and it's challenging to navigate
and understand the differences.
And customers want to ensure that there
is no gap between tribal knowledge of their deployment
and reality.
So our goal is to allow you to navigate
the visualization of your network
with structure and insights so that network monitoring
and troubleshooting becomes easier for you.
You save time, and in many cases avoid network issues
altogether.
Let's start by seeing a visualization
of your project, which is your current deployment within GCP.
On the top, you can see all the external clients.
We have traffic going to three geographic regions here--
Americas, EMEA, and APAC.
You can drill down into any of these
and see which specific countries the traffic is
coming from or being served to.
In the middle, you have load balancers.
Again, you can drill in and see all the different load
balancers deployed.
On the bottom here, you have your GCE instances
and the regions that they're deployed in.
You can drill down to the specific VM instance
level as needed.
Many customers want to use this to quickly verify
certain policies.
For instance, let's say you have a policy
in which all the traffic should be going through the load
balancers.
You can click on the GCE region or an external geo region
to see all the traffic and verify the policy.
Here you can see that there is some traffic going directly
from a GCE instance to the internet.
Another example of a common use case for customers
is to proactively verify if the traffic is being served out
of the optimal region.
For instance, here you can see that the APAC clients
are being predominantly served out of the Asia East region.
This would help you troubleshoot performance issues that
may happen as a result of traffic being served out
of a non-optimal region.
You would be able to easily see which regions the traffic
is being served out of.
You can also see the evolution of topology
by going back in time by clicking
on this timeline on the bottom.
This is very useful in several scenarios.
For instance, if a network event happened
and you want to troubleshoot it, you can look at the topology
around the event using this capability
to determine any topology changes you
may have contributed to the network issue.
During migration it helps you to monitor
the state of your deployment as you migrate your workloads,
thus providing better visibility into your migration process
and also letting you track it by looking
at the topology evolution through time.
For troubleshooting, the search capability is very helpful.
For instance, if you wanted to search for a specific instance
and see what all it was talking to or a specific load balancer,
you can do all those kinds of search using this capability.
That way you can drill down into exactly what
you're searching for.
All edges in the visualization have metrics
associated with them.
You can click on any edge and view how the metric changed
over a period of time.
You can see throughput in these metrics, ingress and egress
byte counts, and others for monitoring your network health.
If you have VPC Flow Logs available
and you want to drill in more to analyze
those logs, to make it simple, we
show you the query to the actual flow logs that
contributed to this traffic.
You can click on this link, which will create the query
and show you the flow logs.
You could also use some of these metrics for optimizations.
For instance, I am only looking at the regions here
and how you could do certain optimizations by understanding
what's contributing to egress traffic across regions.
Here I'm looking at traffic from US Central 1 to Europe West 1.
And lastly, you can also look at your topology
at the organization level to get an overview of all
your projects.
You can see how your projects are talking to each other
and verify that it meets your intent.
Congratulations.
You're all set up to start using the network topology
module and Network Intelligence Center
to visualize, monitor, and troubleshoot your network.
