Deno 2.9 secure-by-default JavaScript/TypeScript runtime on Ubuntu 24.04 LTS by cloudimg. Built-in TypeScript support, a single binary with no node_modules, and a permissions sandbox with no ambient filesystem/network/environment access unless explicitly granted. Pre-deployed with a demo HTTP API proving real dynamic execution under least-privilege permissions. MIT licensed.
Deno is a modern, secure-by-default JavaScript and TypeScript runtime - built-in TypeScript support with no separate compile step, a single binary with no node_modules, and a permissions sandbox that blocks filesystem, network and environment access unless explicitly granted. The cloudimg image installs the official pinned Deno v2.9.2 release binary on Ubuntu 24.04 LTS, verified against a sha256 checksum, on the system PATH for every user.
Deno has no admin console or login, so this image ships a small demo Deno.serve() HTTP API pre-deployed and running under systemd, returning a live server timestamp and a request counter that change on every call - proof the runtime is genuinely executing code per request, not serving a static file. The systemd unit grants ONLY --allow-net, scoped to the loopback address and port the demo binds - no filesystem, environment, subprocess or FFI access - a working demonstration of Deno's sandboxing model, not just a marketing claim. The demo is bound to loopback only, fronted by nginx on port 80 with an unauthenticated health check endpoint for load balancers.
Deploy your own TypeScript or JavaScript app by dropping it into a new directory on the dedicated 20 GiB Azure data disk and adding a systemd unit that grants only the permissions your app actually needs. Application code and data persist independently of the OS disk. The image ships with the latest security patches applied at build time and stays current through unattended upgrades.
Deno is MIT licensed - free and open source, no per-CPU or per-deployment fee. Backed by 24/7 cloudimg support with a guaranteed 24 hour response SLA, separate from the upstream open-source project.
