Proactive Microservice Orchestration in Space–Air–Ground Integrated Networks Using Scout Containers

Abstract

This work explores the problem of microservice orchestration in integrated networks based on efficient deployment methods. A set of methods for orchestrating microservices in dynamic distributed environments with limited and intermittent communication channels was developed and evaluated. After analyzing the architecture of integrated networks and URLLC requirements, an approach using scout containers for predicting and proactively initiating migration was proposed. Using hardware-virtual and virtual rigs emulating real-world conditions, results were obtained on deployment time, migration success, the impact of losses, latency, and jitter, and the resource intensity of the scout containers was assessed. The proposed approach reduced downtime to a few seconds and significantly reduced the load on computing nodes. Based on a comparative analysis of reactive migration, proactive scheduled migration, a scout container, and a hybrid strategy, practical recommendations were developed for selecting and configuring orchestration parameters to ensure stable and rapid service delivery under limited communication conditions.
