The escalation of cloud computing infrastructures into large-scale, dynamic, and multi-tenant environments has rendered static resource allocation policies increasingly inadequate. Fluctuating workloads, heterogeneous hardware, cost constraints, and service-level agreements demand adaptive, real-time decision-making. Deep reinforcement learning (DRL), which combines deep neural networks with reinforcement learning principles, has emerged as a promising paradigm for learning optimal resource allocation strategies directly from interaction with complex environments. This paper presents a comprehensive systems-oriented analysis of DRL for dynamic resource allocation in cloud computing. Rather than focusing on algorithmic innovations in isolation, we examine the structural trade-offs inherent in DRL-based architectures, including the tension between exploration and exploitation, the overhead of state representation, and the stability of training under non-stationary workloads. We discuss deployment considerations such as online learning versus offline pre-training, the role of simulation environments, and the implications for software-defined infrastructure governance. Special attention is paid to robustness and fairness: DRL policies must not only optimize average performance but also mitigate tail latency, prevent resource starvation among tenants, and adapt to adversarial or anomalous traffic patterns. Policy and governance dimensions, including accountability, transparency, and auditability of learned policies, are explored using cross-domain comparisons from autonomous vehicles and energy systems. The paper also addresses sustainability, questioning whether DRL-driven optimization can reduce energy consumption without compromising performance. Through detailed conceptual analysis and illustrative case studies in video streaming and data analytics platforms, we highlight the real-world challenges of deploying DRL at scale. We conclude by identifying open research directions, including multi-agent formulations, federated learning for privacy-preserving policy sharing, and the integration of causal inference to improve generalization. This work aims to provide a bridge between reinforcement learning theory and the practical realities of cloud resource management, offering a roadmap for researchers and engineers alike.
