2. Platform as a Service (PaaS)

3. Software as a Service (SaaS)

Infrastructure as a Service (IaaS)

form of cloud computing that provides virtualized computing resources over the internet

Platform as a Service (PaaS)

form of cloud computing in which a third-party provider delivers hardware and software tools

Software as a Service (SaaS)

form of cloud computing that provides you with a completed product that is run and managed by the

Cloud Computing Deployment Models

1. Cloud

2. Hybrid

3. On-premises

Cloud Deployment Model

application is fully deployed in the cloud and all parts of the application run in the cloud

Hybrid Deployment Model

infrastructure and applications are connected between cloud-based

resources and existing resources not in the cloud

On-premises Deployment Model
