DAVID TU: Hey.
This is David Tu.
I'm a network specialist at Google Cloud.
Welcome back to What's New in Networking.
Today we'll guide you through our new load balancing
and service networking launches.
First our new features around external and internal load
balancers.
Next we'll take a quick stop discussing Traffic Director.
And we'll finish off our journey with Private Service Connect.
Stay tuned.
First stop is our External Network Load Balancer.
The Network Load Balancer is a regional pass-through load
balancer that distributes TCP and UDP
traffic among virtual machines in the same region.
As you might know, the network load balancer
leverages target pools or target instances.
With the recent launch, we've enabled the use
of regional back-end services.
Similar to target pools, a back end service
defines how cloud load balancing distributes traffic.
But now backend service configurations
give you fine-grained control over how
your load balancers behave.
It contains a set of values like protocols, distribution
and settings, health checks, and timeouts.
So what does this launch mean?
First, this launch gets feature parity
for the same backend services as other Google Cloud Load
Balancers, like our Global Load Balancer or our TCP and SSL
proxy load balancer.
Second, it transitions from legacy health checks
to unified health checks, which allows you
to configure TCP health checks.
Third, it enables connection draining.
And lastly, it enables failover groups.
All right, now let's move on to what's
new with the internal network load balancer.
Prior to this launch, if you were ever
required to send traffic to a single internal load balancer
virtual IP, you were limited to only one forwarding rule
per virtual IP address.
With this launch, you'll now be able to configure
multiple forwarding rules with the same virtual IP.
Now you'll have the flexibility to define
different protocols, such as TCP or UDP, to the same virtual IP.
In addition, you have the flexibility
to have multiple forwarding rules to the same virtual IP,
but exposing different ports.
This launch gives you the ability
to have various forwarding rules combinations pointing
to the same virtual IP.
Now that we've covered our load balancers,
let's cover two new additions to Traffic Director,
our fully managed traffic control plane for service mesh.
Introducing TCP services support for Traffic Director.
This feature enables you to use Traffic Director to route
traffic to services that expect non-HTTP traffic,
such as databases or voice over IP services.
Those of you who have TCP-based services
get global load balancing for multi-region services,
such as cross regional failover and overflow,
a fully managed control plane for TCP traffic,
a consistent control plane across L4 and L7 traffic,
and you can easily connect workloads to external services.
For those of you that use proxyless gRPC with Traffic
Director and need additional visibility,
now you can, with observability for proxyless gRPC.
You're able to access monitoring and tracing
metrics that help you solve configuration and networking
issues with your deployment.
Best of all, you can export these metrics to cloud
monitoring and cloud trace.
You can then build dashboards and charts
and even use them as a basis for automating alerts.
Our last feature is Private Service Connect
for Google APIs.
Prior to this launch, there were two ways
of connecting to Google APIs.
The first is over the public internet.
This requires your client to have a public IP
or go through NAT to hit a public API endpoint.
The second was to configure private Google access.
Private Google access removed the requirement
to have a public IP or go through NAT.
Now your clients can privately route traffic
to private endpoint IPs that Google defines.
With the launch of PSC from Google APIs,
you have the ability to create multiple custom
endpoints of your choosing.
Now you get more control over which APIs hit which endpoint
and it remains completely private to your VPC.
And that's what's new in networking for load balancing
and service networking.
Thanks for sticking around till the end.
I welcome you to start using these features
and be sure to take a look at the links
below for guides on how to use them.
Stay tuned for the next What's New in Networking.
