<strong>Hardened Images Are Free. Now What? (6 minute read)</strong>

<br>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Docker has made its Hardened Images (DHI) free, now covering over 1,000 images, including Alpine, Debian, databases, and runtimes. This move simplifies container vulnerability management by providing Docker-owned security fixes, enhanced supply chain isolation, and VEX attestations to reduce scanner noise and improve compliance.

OpenTelemetry continues rapid adoption as a core CNCF observability project, with guidance on choosing between centralized Collectors and lightweight agents. Collectors handle scalable aggregation and processing, while agents capture low-overhead telemetry close to applications, often used together.
