Introducing Budget Controls for AWS: Automatically Manage Your Cloud Costs

**Budget Controls for AWS** just got better. The open-source tool now reins in more than just EC2. It wrangles **RDS Aurora**, **SageMaker**, and **OpenSearch** too. Under the hood, it taps **AWS Budgets**, **AWS Config**, and **custom tags** to watch spend like a hawk. Hit a budget threshold? It c.. read more

%CPU Utilization Is A Lie

Stress tests on the Ryzen 9 5900X uncovered a big gap between **reported CPU utilization** and what the chip actually pushes. Around 50% on paper? Could mean close to full throttle in reality—thanks to sneaky behaviors from **SMT resource sharing** and **Turbo frequency scaling**. **Takeaway:** Raw.. read more

Fast, Secure Kubernetes with AKS Automatic

Azure dropped **AKS Automatic**, a new managed Kubernetes tier that tries to do it all—so you don’t have to. It comes with baked-in best practices: autoscaling via HPA, VPA, KEDA, and Karpenter. Automated patching. Node repair. Monitoring. All wired up by default. You still get full access to the .. read more

v1.34: DRA Consumable Capacity

Kubernetes 1.34 rolls in **consumable capacity** for Dynamic Resource Allocation (DRA). That means device plugins can now carve up resources—GPU memory, NIC bandwidth, etc.—into precise slices for Pods, ResourceClaims, and namespaces. The scheduler tracks it all, so nothing spills over... read more

Kubernetes Security: Best Practices to Protect Your Cluster

A new JetBrains IDE plugin throws Kubernetes security best practices straight into your deployment manifests—right where they belong. Think: checks for `runAsRoot`, privileged mode, `hostPath`, host ports, and sketchy sysctls. No hand-waving. It enforces stuff like: - Default `runAsNonRoot` - Drop .. read more

v1.34: Decoupled Taint Manager Is Now Stable

Kubernetes 1.34 graduates the taint eviction controller to GA. Now, the node lifecycle controller only applies taints, while a dedicated taint eviction controller manages pod eviction. First split in 1.29, now stable in 1.34... read more

v1.34: Pods Report DRA Resource Health

Kubernetes v1.34 lands with an alpha upgrade to **[KEP-4680](https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/4680-add-resource-health-to-pod-status)**, pushing **Dynamic Resource Allocation (DRA)** into smarter territory: health-aware Pods. DRA drivers can now stream device heal.. read more

Secure Boot Advanced Targeting (SBAT): Scaling Boot Security 🔐

Discover how SBAT enhances Secure Boot by introducing a smarter way to handle vulnerabilities, reducing overhead, and ensuring your system's boot process stays secure. Learn how it works, how it addresses scalability, and why it's a game-changer for modern boot security across Linux and Windows envi..

KB-Secure Boot Advanced Targeting
Sigstore is an open source initiative designed to make software artifact signing and verification simple, automatic, and widely accessible. Its primary goal is to improve software supply chain security by enabling developers and organizations to cryptographically prove the origin and integrity of the software they build and distribute.

At its core, sigstore removes many of the traditional barriers associated with code signing. Instead of managing long-lived private keys manually, sigstore supports keyless signing, where identities are issued dynamically using OpenID Connect (OIDC) providers such as GitHub Actions, Google, or Microsoft. This dramatically lowers operational complexity and reduces the risk of key compromise.

The sigstore ecosystem is composed of several key components:

- Cosign: A tool for signing, verifying, and storing signatures for container images and other artifacts. Signatures are stored alongside artifacts in OCI registries, rather than embedded in them.

- Fulcio: A certificate authority that issues short-lived X.509 certificates based on OIDC identities, enabling keyless signing.

- Rekor: A transparency log that records signing events in an append-only, tamper-evident ledger. This provides public auditability and detection of suspicious or malicious signing activity.

Together, these components allow anyone to verify who built an artifact, when it was built, and whether it has been tampered with, using publicly verifiable cryptographic proofs. This aligns closely with modern supply chain security practices such as SLSA (Supply-chain Levels for Software Artifacts).

sigstore is widely adopted in the cloud-native ecosystem and integrates with tools like Kubernetes, container registries, CI/CD pipelines, and package managers. It is commonly used to sign container images, Helm charts, binaries, and SBOMs, and is increasingly becoming a baseline security requirement for production software delivery.

The project is governed by the OpenSSF (Open Source Security Foundation) and supported by major industry players.
