Master Kubernetes with this a 4-day Advanced Kubernetes workshop on the 22nd of September (in 2 weeks)!

_What should you expect?_

- Learn how to architect and design clusters from the ground up (in the cloud or on-prem).
- Explore the Kubernetes internal component and how the system is designed with resiliency in mind.
- **Deep-dive into the networking components and observe the packets flowing into the cluster.
- Hands-on labs to test the theory with real-world scenarios!

The article starts with a recap of Kubernetes resource management and its core concepts of requests and limits.

Then it discusses those static limits in the realm of pod autoscalers, such as HPA, VPA, and KPA.

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.

In this blog post, you'll learn a few tips for running highly available applications on Kubernetes:

1. Using deployments.
2. RollingUpdate update strategy.
3. Spreading pods.
4. Pod disruption budgets.

version-checker is a Kubernetes utility for observing the current versions of images running in the cluster and the latest available upstream.

These checks get exposed as Prometheus metrics to be viewed on a dashboard or soft alert cluster operators.

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.

Ephemeral Containers are not a new feature and have been around for a while.

However, it has finally graduated to BETA in the Kubernetes v1.23 release and is enabled by default.

In this article, you will learn how to use them.

Kube-capacity is a simple and powerful CLI that provides an overview of the resource requests, limits, and utilization in a Kubernetes cluster.

It combines the best parts of kubectl top and describe into an easy to use CLI focused on cluster resources.

Paralus is a tool that enables controlled, audited access to Kubernetes infrastructure.

It comes with just-in-time service account creation and user-level credential management that integrates with your RBAC and SSO.

Ships as a GUI, API, and CLI.

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.
