Shift 1: Hardware → Software-Defined Vehicle • Vehicle value shifts from hardware to software • Shift 2: Close → Open Standards & Consortiums • Siloed, proprietary systems limit scalability • Shift 3: Linear Supply Chain → Ecosystem • The traditional OEM and Tier 1 hierarchy is changing
shifts from hardware to software • Functions are defined and updated by software • Over-the-air (OTA) updates enable continuous evolution • The vehicle becomes a software-driven platform
Siloed, proprietary systems limit scalability • Common data models and APIs enable interoperability • Industry consortiums (e.g., JasPar) drive standardization • OEMs focus on differentiating software and services
OEM and Tier 1 hierarchy is changing • Semiconductor, cloud, and software players gain importance • Value is created through cross-industry collaboration • OEMs increasingly act as ecosystem orchestrators EdgeTech+WEST2026

metal hypervisor. It runs as the most privileged piece of software, and shares the resources of the hardware between virtual machines. In Xen terminology, there are domains, commonly abbreviated to dom, which are identified by their numeric domid. When Xen boots, dom0 is automatically started as well. Dom0 is a virtual machine which, by default, is granted full permissions https://xenbits.xen.org/docs/latest/admin-guide/introduction.html

device virtualization technology) VirtIO is an open standard for device I/O in virtual environments. It allows the same drivers and device models to work across different operating systems, hypervisors, and hardware. The specification is developed and maintained as an international standard by OASIS. -OASIS activities: defining and maintaining the VirtIO specification OASIS operates the Virtual I/O Device (VIRTIO) Technical Committee.This committee publishes and updates the VirtIO specifications (such as VirtIO v1.1 and v1.2) as official Committee Specifications.This ensures an open, neutral standard without vendor lock-in. https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=virtio#overview
