Modal Is a Computer: Recasting the Cloud Platform as a Machine

Modal argues it should be understood as a computer rather than an "Uber for compute," a neocloud, or an inference provider, since it sells processor-seconds and byte-seconds rather than tokens. The post maps a conventional machine's ALU, memory hierarchy, I/O, NIC, and operating system onto Modal's containers, object storage, Input/Output Plane, Routing Plane, and Tunnels. It also aligns Modal Functions, Sandboxes, and Servers with stateless tools, Linux processes, and HTTP listeners.
