Cloud computing showdown: Public vs. private cloud explained
Pankaj Kumar Gupta · World Journal of Advanced Engineering Technology and Sciences · 2025
Cloud computing has fundamentally changed how organizations deploy, manage, and scale IT resources, with the public versus private cloud decision emerging as a critical strategic choice. This distinction encompasses key differences in ownership, cost models, scalability, security approaches, performance characteristics, and customization capabilities that significantly impact business operations. Public cloud excels for organizations with limited capital, variable workloads, development environments, cloud-native applications, and global deployment needs. Conversely, private cloud better serves regulated industries, stable high-utilization workloads, specialized computing requirements, legacy applications, and sensitive data environments. Hybrid cloud has evolved as a compelling middle ground, enabling optimized workload placement, cost efficiency, risk mitigation, gradual migration, and compliance with data residency requirements across diverse sectors including financial services, healthcare, manufacturing, retail, and technology.
