A Comparative Study of Cloud Securityin Public vs. Private Cloud Environments – Volume 12 Issue 5

Cloud computing is now used by almost every company because it gives flexibility, cost saving, and quick setup. But security is a major issue especially when chosen either public and private clouds. Public clouds are cheap and grow easily nut they are less safe. Private clouds are safe but it cost more. This research tries to find the balance solution by looking at hybrid setup and helps to find out which model give better balanced effective solution. Findings indicate that with correct security tools and policies both models can be easily depending on organizational needs.

• The four areas which are risks, cost, compliance, and security tools are been studied and looked at public vs private cloud security so it will have better use. • From the findings, no single cloud model is perfect for all organizations. • There are good and bad points in every model it dependence on the company. Public Cloud • For having perfect small businesses public clouds are cheap and flexible. • They allow quick scaling when demand increases. • But they face security risks from human errors like bad settings or access control mistakes. • Most attacks happen because of misconfiguration and weak monitoring. Private Cloud • Private clouds give full control over data and system. • They are best for companies that must follow strict rules like GDPR or HIPAA. • Needs more money and skilled people. • Still it need regular checks and internal security to prevent insider threats and leaks. Hybrid Cloud • Hybrid clouds mix public and private benefits. • We keep important things in private cloud and other things in public cloud. • It makes safer and saves money. • Managing hybrid clouds is hard, so we need automation and constant monitoring. Modern Security Tools • Tools like CSPM, Zero Trust Architecture, and AI threat detection are now necessary. • They help find wrong settings, control access, and stop attacks early. • These tools are very useful when using hybrid cloud systems.
