Apache CloudStack vs Inspektor Gadget
A side-by-side editorial comparison of Apache CloudStack and Inspektor Gadget — release velocity, themes, recent moves, and the top alternatives to consider.
Apache CloudStack vs Inspektor Gadget: at a glance
What is Apache CloudStack?
Three LTS branches running in parallel, and the only release notes with substance are the CVE ones.
CloudStack maintains 4.19, 4.20 and 4.22 as concurrent LTS lines with 4.21 as a regular release alongside them, and ships maintenance builds across all of them on a rolling basis. Nearly every release entry is a set of pointers to release notes, install and upgrade docs with no summary of what changed. The exceptions are the security releases, which enumerate their CVEs in full.
What is Inspektor Gadget?
The eBPF observability tool just started reaching for the GPU.
Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.

Apache CloudStack
0.0INFRA · APIS
Three LTS branches running in parallel, and the only release notes with substance are the CVE ones.
◆ Current state
CloudStack maintains 4.19, 4.20 and 4.22 as concurrent LTS lines with 4.21 as a regular release alongside them, and ships maintenance builds across all of them on a rolling basis. Nearly every release entry is a set of pointers to release notes, install and upgrade docs with no summary of what changed. The exceptions are the security releases, which enumerate their CVEs in full.
◆ Where it's heading
The pattern that is legible from the entries is a hardening cycle around tenant isolation. The 4.19.3.0 and 4.20.1.0 advisories covered API-key exposure and cross-domain access; a year later 4.22.0.1 covers backup access control, MinIO policy persistence after bucket deletion, resource-limit enforcement, and cross-tenant instance access through the Proxmox extension. Same class of defect, newer surfaces — the security work is tracking the platform's expansion into backup and third-party hypervisor integrations.
◆ Prediction
Expect the paired-advisory rhythm to continue, with the next security release landing simultaneously across the supported LTS branches as 4.19.3.0/4.20.1.0 and 4.20.3.0/4.22.0.1 both did. What ships in the feature releases is not something these entries let you predict — they carry no change detail at all.
Inspektor Gadget
6.3INFRA · APIS
The eBPF observability tool just started reaching for the GPU.
◆ Current state
Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.
◆ Where it's heading
Two directions run in parallel. The kernel-side surface keeps growing — SockOps, SkSKB and SkMsg program types, map pinning, non-destructive map iteration, OTel and Python stack symbolization — which makes the tool a more general eBPF runtime rather than a fixed set of gadgets. Meanwhile the output side is becoming opinionated about ecosystems it serves: v0.54.0 taught advise_networkpolicy to emit Cilium NetworkPolicy resources alongside Kubernetes ones. GPU telemetry extends the first direction past the boundary eBPF normally stops at.
◆ Prediction
The GPU work is explicitly described as an initial design laying groundwork, so expect the next releases to build actual gadgets on top of the bridge rather than to expand it further; the pinned-map plumbing added in the same release is what those gadgets would consume.
