| | | | | | | | | | 2023 Kubernetes Benchmark Report: How Do Your Kubernetes Workloads Compare? | | | | | Kubernetes adoption is increasing and organizations are paying more attention to the reliability, security, and cost efficiency of their workloads. Fairwinds has released an updated Kubernetes Benchmark Report for 2023, based on data from 150,000 workloads, to help organizations understand their container configurations and compare them to their peers.
The report shows that Kubernetes security, cost efficiency, and reliability remain top concerns for cloud native users. It also reveals that many organizations are not aligning their configurations to best practices, which can lead to unnecessary risk, cloud cost overruns, and poor application performance.
The report also states that DevOps teams are outnumbered as Kubernetes usage expands and it becomes harder for them to manage the potential configuration risks introduced by new teams. The report is divided into three sections: reliability, security, and cost efficiency, to help organizations identify where they may be lagging behind and how to improve their configurations. |
| | | | | | | | | | Upgrading Kubernetes - A Practical Guide | | | | | The author discusses the process of upgrading a legacy Kubernetes cluster and tips and tricks to make the process easier. They emphasizes the importance of regular upgrades, as k8s releases new versions quickly and has a support policy of N-2, meaning the 3 most recent minor versions receive security and bug fixes.
The tutorial suggests a staggered approach to upgrading, with the dev cluster being as close to bleeding edge as possible, staging a minor release behind dev, and production as close to staging as possible. It also advises to wait until a minor version hits patch .2 at least before upgrading, and to use per-environment YAMLs and automated tools like Kustomize. |

| | | | | | | | | | What Threatens Kubernetes Security and What Can You Do About It? | | | | | Kubernetes adoption has become widespread, with 96% of organizations using or evaluating it for container orchestration. However, Kubernetes also presents security risks due to the flexibility of container applications and their ability to carry discrete components that interact over the network.
These risks include compromised container images or containers, misuse of a container to attack other containers or hosts, registry risks, orchestrator risks, vulnerabilities in runtime software, and host operating system risks. Malicious actors often attack Kubernetes by exploiting misconfigurations or specific vulnerabilities in exposed ports.
To secure Kubernetes environments, organizations should align cluster configurations with security best practices, ensure applications running on the cluster have no known vulnerabilities, enforce runtime security policies, and protect credentials.
The "defense-in-depth" approach is recommended, using the "4C Security Model" which covers cloud, cluster, container, and code layers. Automation tools such as Kubescape can also help with risk management and compliance. |
