Reducing infrastructure costs boils down to turning apps off when you don't use them.

However, the challenge is figuring out how to turn them on automatically when needed.

Take the example of a Kubernetes dev cluster: you might want not to run any service during the weekend.

In this webinar, Salman will demo live how you can use KEDA and the HTTP scaler to intercept and monitor the requests to your services and scale your pods accordingly.

In the process, you will discover how you can scale to zero and create pods only when you need them.

Over 900k Kubernetes exposures were observed across the internet during a routine threat-hunting exercise.

While this does not imply that all exposed instances are vulnerable to attacks, it still makes them a target.

You can learn more in this report.

When your Kubernetes cluster runs low on resources, the Cluster Autoscaler provision a new node and adds it to the cluster.

The cloud provider has to create a virtual machine from scratch, provision it and connect it to the cluster.

The process could take more than a few minutes from start to end.

But there's an alternative: you can proactively create nodes that are already provisioned when you need them.

In this webinar, Chris will demo live how you can configure Pod Priorities and a placeholder pod to pre-warm node instances for quicker scaling.

One interesting challenge with Kubernetes is deploying workloads across several regions.

While you can technically have a cluster with several nodes located in different regions, this is generally regarded as something you should avoid due to the extra latency.

Another popular alternative is to deploy a cluster for each region and find a way to orchestrate them.

In this webinar, Daniele will demo live how to create, connect and operate three Kubernetes clusters in different regions.
