In the era of big data, distributed systems have become the backbone of real-time data processing across multi-cloud environments. This paper explores the architectural principles and design considerations for building robust, scalable, and efficient distributed systems that operate seamlessly across diverse cloud providers. The study delves into the complexities of multi-cloud environments, including challenges such as data fragmentation, inter-cloud communication latency, and security. It highlights the use of modern tools and frameworks for real-time data ingestion, processing, and analytics, with a focus on stream processing and event-driven architectures. Additionally, the paper emphasizes the role of microservices, container orchestration, and serverless computing in achieving high availability and fault tolerance. Key considerations for compliance, cost optimization, and interoperability are also discussed. By providing practical strategies and case studies, this work aims to equip architects and engineers with actionable insights for designing distributed systems that meet the demands of real-time processing while leveraging the flexibility and resilience of multi-cloud deployments
