Container runtimes form the operational backbone of Software-Defined Vehicles (SDVs), extending principles from internet infrastructure into the automotive domain. While containers already power modern cloud services, adapting them for automotive applications comes with unique challenges and requirements.
Key Requirements for Automotive Container Runtimes include Fast and Deterministic Startup Times, Resource Optimization and Enhanced Security and Efficient Updates:
Fast and Deterministic Startup Times: In vehicles, startup delays are unacceptable. Imagine unlocking a car and waiting several seconds for critical services like the vehicle experience interface to boot. Automotive-grade container runtimes must ensure near-instant responses, supporting real-time or near-real-time applications even within QM environments.
Resource Optimization: Onboard compute systems face hardware constraints despite using high-performance processors. Unlike cloud environments, onboard systems cannot scale elastically. Therefore, efficient resource allocation is essential, ensuring that containerized services run smoothly within limited computational resources.
Enhanced Security and Efficient Updates: Automotive containers require robust security measures, such as isolation between services, secure boot mechanisms, and protection against cyber threats. Efficient update mechanisms must support seamless over-the-air (OTA) updates with minimal downtime.
In an automotive E/E architecture, container runtimes fit within the broader system structure, enabling flexible and scalable service deployment:
Central Compute Unit: This unit hosts multiple instances of operating systems, often using virtualization technologies like hypervisors.
Virtual OS Instances: Inside these virtual machines, container runtimes manage microservice deployment.
Container Runtimes: Lightweight and modular, these environments host one or more microservices, creating a service-oriented architecture.
Microservices: Each microservice runs independently, providing modular vehicle functionalities. Multiple containerized services can run simultaneously, ensuring robust and scalable performance.
By integrating container runtimes, Software-Defined Vehicles achieve the scalability, modularity, and reliability needed for modern automotive functions while ensuring seamless interaction with off-board cloud services. This combination enables real-time applications, over-the-air updates, and enhanced service delivery, forming the technological backbone of next-generation automotive platforms.
