JCC 2026JCC 2026 is a premier global forum for sharing cutting-edge research and industrial insights into scalable, intelligent JointCloud computing. The conference will be held on 27-30 July, 2026 in a hybrid format, with the physical venue located in Fukuoka, Japan. We invite original contributions in JointCloud computing and at its intersection with advanced AI technologies. Modern enterprises increasingly rely on multi-cloud and hybrid-cloud strategies to orchestrate services across providers, optimize performance, and avoid vendor lock-in. Yet, this distributed paradigm introduces significant challenges in interoperability, security, management, scalability, and intelligent orchestration. JointCloud encompasses hybrid-cloud, multi-cloud, federated cloud, cloud-edge integration, computing network convergence, and blockchain-based systems, serving as the architectural backbone for next-generation cloud ecosystems. JCC 2026 is committed to fostering a leading global platform for exchanging cutting-edge research, sharing practical insights, and identifying future directions that will define the era of scalable, intelligent computing.
