Question
What are the different cloud deployment models?
Solution
Public Cloud (AWS, Azure, GCP) is where infrastructure is owned by CSP, shared among multiple tenants on pay-per-use and it is highly scalable. Private Cloud is a dedicated infrastructure for a single organization, on-premise or hosted, with higher control and security. Hybrid Cloud is a combination of public and private, where data/workloads move between them. Community Cloud is shared among organizations with common interests (e.g., multiple banks sharing a compliant cloud). RBI guidelines allow banks to use cloud but mandate data residency in India and rigorous vendor due diligence.
