Microsoft Azure vs Clair
A side-by-side editorial comparison of Microsoft Azure and Clair — release velocity, themes, recent moves, and the top alternatives to consider.
Microsoft Azure vs Clair: at a glance
What is Microsoft Azure?
Azure flips a stack of preview-to-GA promotions while quietly retiring a long tail of legacy VM reservations.
Azure is wrapping up several preview-to-GA arcs at once. Elastic SAN gained three GA capabilities in a single drop (single volume snapshots, AVS Gen2 Private Cloud support, AV64 SKU support), AKS got Application Gateway for Containers as a managed add-on in AKS Automatic, and Azure Functions added Java 25 support and a Consumption SKU for the Durable Task Scheduler aimed at AI agent orchestration. On the lifecycle side, one-year Reserved VM Instance purchases retire on July 1, 2026 across 14 legacy VM series.
What is Clair?
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

Azure flips a stack of preview-to-GA promotions while quietly retiring a long tail of legacy VM reservations.
◆ Current state
Azure is wrapping up several preview-to-GA arcs at once. Elastic SAN gained three GA capabilities in a single drop (single volume snapshots, AVS Gen2 Private Cloud support, AV64 SKU support), AKS got Application Gateway for Containers as a managed add-on in AKS Automatic, and Azure Functions added Java 25 support and a Consumption SKU for the Durable Task Scheduler aimed at AI agent orchestration. On the lifecycle side, one-year Reserved VM Instance purchases retire on July 1, 2026 across 14 legacy VM series.
◆ Where it's heading
Azure is doing two things in parallel. It's compressing storage and networking previews into GA so AVS, AKS, and Elastic SAN converge into a more coherent enterprise platform. And it's pruning the back catalog — older VM series losing reservation eligibility and ACS forcing migration off legacy AlternateId — clearing the deck for a tighter set of supported configurations.
◆ Prediction
Expect more legacy SKU retirements through the year as Azure consolidates around current VM families. The Durable Task Scheduler Consumption SKU is positioned squarely for agent orchestration, so look for tighter integration between Azure Functions, AI Foundry, and the agent runtimes that have been shipping recently.
Clair
2.5INFRA · APIS
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
◆ Current state
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
◆ Where it's heading
Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.
◆ Prediction
More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
