PREEMPT-FaaS: Taming Orchestration Times in Latency-Sensitive Serverless Environments

Authors: Marcello Cinque, Luigi De Simone, Raffaele Della Corte, and Stefano Toscano

Published in: LIPIcs, Volume 375, 38th European Conference on Real-Time Systems (ECRTS 2026)

Abstract
The orchestration of application instances is critical for the efficient management of cloud computing platforms. Specifically, the serverless paradigm automates container spawning and de-spawning based on actual load, mitigating inefficiencies, such as over- and under-provisioning, that might compromise Service Level Objectives (SLOs). This dynamic behavior introduces significant challenges concerning initialization and termination latencies, which are exacerbated when enforcing real-time requirements in mixed-criticality systems. The existing literature already addresses key issues, such as reducing cold-start times and assuring real-time performance to deployed instances. However, container orchestration times remain an overlooked factor that can severely affect instance startup times, especially when the orchestrator is subject to intense workloads. In this paper, we present PREEMPT-FaaS, an orchestration controller that, unlike commonly adopted controllers, adopts a fixed-priority preemptive scheduling of requests to guarantee reduced orchestration times to high-priority and highly critical instances. We implemented PREEMPT-FaaS as a Rust custom controller for Kubernetes (K8s), along with a patch for Knative, a popular serverless platform built upon K8s. We perform an extensive experimental campaign of PREEMPT-FaaS, including the serving of AI workloads, such as, recurring neural networks and video analytics, showing up to ∼6× reduction of orchestration times under high load and improving end-to-end cold-start times of critical instances, with a consequent reduction of service-level latencies (up to ∼2 s reduction under stress at the 95th percentile).

Achieving Isolation in Mixed-Criticality Industrial Edge Systems with Real-Time Containers (Artifact)

Authors: Marco Barletta, Marcello Cinque, Luigi De Simone, and Raffaele Della Corte

Published in: DARTS, Volume 8, Issue 1, Special Issue of the 34th Euromicro Conference on Real-Time Systems (ECRTS 2022)

Abstract
Real-time containers are a promising solution to reduce latencies in time-sensitive cloud systems. Recent efforts are emerging to extend their usage in industrial edge systems with mixed-criticality constraints. In these contexts, isolation becomes a major concern: a disturbance (such as timing faults or unexpected overloads) affecting a container must not impact the behavior of other containers deployed on the same hardware. In this artifact, we propose a novel architectural solution to achieve isolation in real-time containers, based on real-time co-kernels, hierarchical scheduling, and time-division networking. The architecture has been implemented on Linux patched with the Xenomai co-kernel, extended with a new hierarchical scheduling policy, named SCHED_DS, and integrating the RTNet stack. Experimental results, presented in the related scholarly paper, are promising in terms of overhead and latency compared to other Linux-based solutions. More importantly, the isolation of containers is guaranteed even in presence of severe co-located disturbances, such as faulty tasks (elapsing more time than declared) or high CPU, network, or I/O stress on the same machine.

RT-CASEs: Container-Based Virtualization for Temporally Separated Mixed-Criticality Task Sets

Authors: Marcello Cinque, Raffaele Della Corte, Antonio Eliso, and Antonio Pecchia

Published in: LIPIcs, Volume 133, 31st Euromicro Conference on Real-Time Systems (ECRTS 2019)

Abstract
This paper presents the notion of real-time containers, or rt-cases, conceived as the convergence of container-based virtualization technologies, such as Docker, and hard real-time operating systems. The idea is to allow critical containers, characterized by stringent timeliness and reliability requirements, to cohabit with traditional non real-time containers on the same hardware. The approach allows to keep the advantages of real-time virtualization, largely adopted in the industry, while reducing its inherent scalability limitation when to be applied to large-scale mixed-criticality systems or severely constrained hardware environments. The paper provides a reference architecture scheme for implementing the real-time container concept on top of a Linux kernel patched with a hard real-time co-kernel, and it discusses a possible solution, based on execution time monitoring, to achieve temporal separation of fixed-priority hard real-time periodic tasks running within containers with different criticality levels. The solution has been implemented using Docker over a Linux kernel patched with RTAI. Experimental results on real machinery show how the implemented solution is able to achieve temporal separation on a variety of random task sets, despite the presence of faulty tasks within a container that systematically exceed their worst case execution time.
