Kubernetes Logging and Monitoring: What Kubernetes Can and Can't Do Natively

Kubernetes is a container orchestration tool, but its functionality extends far beyond just orchestrating containers in a narrow sense. It offers a range of additional features that—to a limited extent—address needs such as load balancing, access control, security policy enforcement, and even logging and monitoring. Indeed, Kubernetes’s broad functionality has led some folks to call it an “operating system” in its own right.

Monitor containers on Amazon Bottlerocket with Datadog

Amazon’s Bottlerocket is a new Linux-based open-source operating system that’s designed with containers in mind. Bottlerocket is optimized and stripped down to only the essential software needed to run containers. You can apply updates to Bottlerocket in a single step, and roll them back instantly if necessary. And, because it’s open-source, you can customize the operating system to fit your specific needs.

Secure and monitor your containers on Bottlerocket from AWS

Sysdig is pleased to support AWS today in their GA launch of Bottlerocket, a special-purpose operating system designed for hosting Linux containers. Orchestrated container environments run potentially hundreds of compute nodes. Operating general-purpose Linux on container hosts introduces complexity for IT teams who must patch and update packages across their clusters. Worse, features and packages that are not necessary for running containers, introduce unnecessary security exposure.

Do containers and Kubernetes actually reduce AWS costs?

In surveys about why organizations adopt Kubernetes, a desire to reduce overall IT costs is an oft-cited reason for adopting containers and Kubernetes. Yet after the fact, when organizations talk about surprises during Kubernetes adoption, many cite increased costs. So does Kubernetes reduce costs or not? Like so many things in life, it depends. Here are some of the reasons Kubernetes projects come in over-budget and how to avoid them.

Guide: Upgrading EKS with Terraform

New Kubernetes versions are released multiple times per year, and you must upgrade your EKS cluster periodically to stay up to date. In this blog post we will go over the steps required to safely upgrade your production EKS cluster managed by Terraform. At Blue Matador, we use Terraform to manage most of our AWS infrastructure, and our EKS cluster is no exception. We use the eks module, which provides a lot of functionality for managing your EKS cluster and worker nodes.

Kubernetes in Production: 6 Key Considerations

Kubernetes is an open-source platform for container orchestration. You can use it to deploy a highly resilient, self-healing infrastructure using automation and infrastructure as code (IaC). Kubernetes includes features for zero downtime deployments, scaling, automatic rollout and rollback of updates, and service discovery. Kubernetes is designed to help you manage container deployments at scale via REST API.

Visibility and Troubleshooting Modern Applications with Calico Enterprise and OpenShift

Red Hat OpenShift is a great platform for hosting microservices, enabling developers to get up and running quickly. However, taking the next step from development to production imposes additional networking, security, and compliance requirements that must be addressed before Kubernetes apps can be widely deployed. Traditional networking tools, which were designed for relatively static IP environments, don’t have the context necessary to identify Kubernetes traffic flows, making it nearly impossible to effectively diagnose, troubleshoot, and resolve application connectivity issues.
