Hello and welcome back to the container master class.
We are back with a significant update this
time, with something that has become the center of
the conversation around the Kubernetes ecosystem.
And that is Kubernetes going serverless.
To put it simply, serverless means not having to worry
about the underlying infrastructure at all.
For example, while operating a regular Kubernetes
cluster, we have seen that the user interacts with
the Master and passes on the request through the Master.
When we use hosted Kubernetes, like Google
Kubernetes Engine, we as users talk to the hosted
Kubernetes service providing platform instead,
like Google Cloud, but we do have to manage the cluster.
We are very well aware of the cluster
configurations and we also have to keep an eye on
the resource utilization to see if we have to
scale the cluster for better load handling.
In other words, hosted Kubernetes allows us to host
and manage the cluster on their resources.
But think about this case, all you need is a working
desktop browser, you have to do a few clicks here
and there, and boom, your containerized
application is live.
That is Serverless Kubernetes.

Behind the scenes or in the backend,
the serverless Kubernetes service provider also
has lots of Kubernetes clusters deployed.
But, you don't have to worry about it. This has a few implications.
First, you do not know the full
details of the cluster that you are operating on.
There are exceptions, but we will get into them later.
Second, the smallest unit of acquisition is
not a bunch of virtual machines anymore.
You're merely given a separate namespace and it is highly
likely that other users are also operating on the
cluster your containers are on.
But you will never clash because of the namespace isolation
and RBAC access policies.
This makes deploying your
applications even faster, economical, and easier.
Google Cloud's Cloud Run is a great example of
Serverless Kubernetes offerings.
In the next lecture, we will get hands on with Cloud Run.
Till then happy learning and I hope you have a great day.
