Multi-Cloud Messaging Platforms: A Comparative Analysis for Enterprise Architectures

Abstract

Multi-cloud architectures have become a predominant strategy in enterprise computing, necessitating robust messaging solutions that span heterogeneous environments. This article examines messaging platforms for multi-cloud deployments, analyzing workload patterns, implementation strategies, architectural approaches, and selection frameworks. The classification of messaging workloads in queue-based, publish-subscribe, and streaming patterns provides a foundation for understanding platform requirements. Three primary implementation strategies: separate trade-closes between portability-first backbones, cloud-country services with abstract layers, and special performance-focused solutions, domination, operational simplicity, and performance. Four architectural patterns emerge as an effective approach: federated cloud-country, integrated streaming backbone, event Aries, and edge-cloud control plane. A systematic decision structure enables organizations to select appropriate message platforms with commercial obstacles and technical barriers, incorporating cementic requirements, performance characteristics, message properties, operational factors, ecosystem integration, and cost structure.
