WHAT IS CLOUD AS A SERVICE?

Infrastructure as a Service (IaaS):

IaaS delivers fundamental computing resources over the internet, typically in the form of virtualized hardware. This includes virtual machines, storage, and networking. Users have the flexibility to scale up or down based on their requirements, and they are responsible for managing applications, data, runtime, and middleware.
Platform as a Service (PaaS):

PaaS provides a higher-level abstraction of computing resources, allowing developers to focus more on building applications and less on managing underlying infrastructure. It typically includes tools and services for development, testing, and deployment. Users are responsible for managing applications and data, while the cloud provider handles the underlying infrastructure.
Software as a Service (SaaS):

SaaS delivers fully functional applications over the internet. Users can access these applications through a web browser without needing to install, maintain, or manage the software locally. Examples of SaaS include email services (e.g., Gmail), customer relationship management (CRM) software (e.g., Salesforce), and productivity tools (e.g., Microsoft 365).
