Cloud services type

Cloud services come in three primary types:

• SaaS (Software as a Service) --> For customers
• PaaS (Platform as a Service) --> For developers
• IaaS (Infrastructure as a Service) --> For Admins

Cloud types

Cloud computing can be deployed in different ways depending on your business needs:

• Public Cloud: Services are delivered over the public internet and shared across multiple users (Known also as Cloud-Native)
• Private Cloud: Cloud infrastructure is used exclusively by one organization—either hosted internally or by a third-party. Ideal for strict security or compliance needs (Known also as On-premise)
• Hybrid Cloud: Combines public and private clouds to allow data and applications to move between them. Offers greater flexibility and optimization
