Recent research in cognitive cloud computing focuses on integrating artificial intelligence, machine learning, and cognitive analytics into cloud environments to create intelligent, self-adaptive, and context-aware systems. These studies explore architectures that enable dynamic decision-making, automated resource management, predictive fault detection, and efficient workload distribution based on real-time data and learning models. Cognitive cloud frameworks aim to enhance user experience by providing personalized and proactive services while optimizing system performance, energy efficiency, and security. Current works also address challenges such as scalability, interoperability, and ethical data handling in cognitive-driven cloud ecosystems, paving the way for next-generation intelligent cloud infrastructures.
