Impact of Kubernetes cluster maintenance on application availability

#kubernetes #eks #chaosengineering
In this video, we will be exploring an interesting scenario that might happen in real life. Let's imagine we have an application running in a Kubernetes cluster inside EKS. If for any reason, two of our three nodes are cordoned and can't be scheduled anymore, what would happen to our users should the last node be cordoned as well? And what if we need to reschedule something?

How to Strengthen Kubernetes with Secure Observability

Kubernetes is the leading container orchestration platform and has developed into the backbone technology for many organizations’ modern applications and infrastructure. As an open source project, “K8s” is also one of the largest success stories to ever emanate from the Cloud Native Computing Foundation (CNCF). In short, Kubernetes has revolutionized the way organizations deploy, manage, and scale applications.

How to Effortlessly Deploy Cribl Edge on Windows, Linux, and Kubernetes

Collecting and processing logs, metrics, and application data from endpoints have caused many ITOps and SecOps engineers to go gray sooner than they would have liked. Delivering observability data to its proper destination from Linux and Windows machines, apps, or microservices is way more difficult than it needs to be. We created Cribl Edge to save the rest of that beautiful head of hair of yours.

How Qovery Could Have Saved Time and Effort in Compare the Market's EKS Migration

During the AWS summit in London, Renee Hunt, the CTO of Compare the Market, shared their journey of migrating from EC2 to EKS and the obstacles they faced along the way. As I listened to their story, I couldn't help but think about how Qovery could have greatly streamlined its migration process; here is my take on the subject.

Maximize Long-Term Savings From Cloud Providers with Densify

One of the first considerations for FinOps teams trying to lower their public cloud spend is investing in long-term savings vehicles available from their Cloud Service Provider. These programs can provide customers with upwards of 72% savings off on-demand prices, in return for a 1-to-3-year usage commitment, so it’s pretty common that we see them in use by our customers.

Monitoring Kubernetes with Prometheus

In part I of this blog series, we understood that monitoring a Kubernetes cluster is a challenge that we can overcome if we use the right tools. We also understood that the default Kubernetes dashboard allows us to monitor the different resources running inside our cluster, but it is very basic. We suggested some tools and platforms like cAdvisor, Kube-state-metrics, Prometheus, Grafana, Kubewatch, Jaeger, and MetricFire.

Neon and Qovery - The Perfect Match for Preview Environments

Hey guys, it's Romaric from Qovery. In this video, I'll show you how to combine Neon, a Postgres serverless solution, with Qovery to easily create and clone Postgres serverless instances. I'll walk you through the process step by step, demonstrating how to spin up a new serverless instance from Neon and connect it to a to-do application. The key point is that with Neon, you can create a branch from the original environment, make changes in the branch, and those changes will only affect that branch, not the parent environment. It's a powerful feature that allows for easy experimentation and isolation. So let's dive in and see how it works!

Troubleshooting and Fixing Kubernetes CrashLoopBackOff

In this post, we'll dive into what CrashLoopBackOff actually is and explore the quickest way to fix it. Fasten your seat belts and get ready to ride. Everyone working with Kubernetes will sooner or later see the infamous CrashLoopBackOff in their clusters. No matter how basic or advanced your deployments are and whether you have a tiny dev cluster or an enterprise multi-cloud cluster, it will happen anyway. So, let’s dive into what CrashLoopBackOff actually is and the quickest way to fix it.

Unveiling Komodor's Network Mapping Capability

I am happy to share that thanks to the power of the open-source community, and our friends over at Otterize, we have now enhanced our Kubernetes offering for developers with another visual aid to streamline operations and troubleshooting – Dependencies Map. The Otterize network mapper is a zero-config tool that aims to be lightweight and doesn’t require you to adapt anything in your cluster.

Database Migrations in the Era of Kubernetes Microservices

In our extensive guide of best ci/cd practices we included a dedicated section for database migrations and why they should be completely automated and given the same attention as application deployments. We explained the theory behind automatic database migrations, but never had the opportunity to talk about the actual tools and give some examples on how database migrations should be handled by a well disciplined software team.
