Question

a paas
b saas
c iaas

Explanation:

• IaaS (Infrastructure - as - a - Service):
• IaaS provides virtualized computing resources over the internet. It offers the fundamental infrastructure like servers, storage, and networking.
• With IaaS, users get features such as fault tolerance (ability to handle component failures without system failure), elasticity (ability to scale resources up or down based on demand), easy and quick scaling (both vertically and horizontally), backup (for data protection), and disaster recovery (to restore systems after a disaster).
• PaaS (Platform - as - a - Service):
• PaaS focuses on providing a platform for developers. It includes tools for application development, testing, and deployment. While it may have some aspects of the cloud's benefits, its main emphasis is on the development platform rather than the full - fledged infrastructure - level features like extensive backup and disaster recovery at the infrastructure scale.
• SaaS (Software - as - a - Service):
• SaaS delivers software applications over the internet. Users access the software directly, and the provider manages the underlying infrastructure. It is more about the software application itself rather than the infrastructure - level enhancements like elasticity and quick scaling of the infrastructure.

Answer:

C. IaaS
