PaaS provides a platform allowing developers to build, deploy, and manage applications without the complexity of infrastructure management. Key features include:
- Development Tools: Integrated development environments streamline app development.
- Scalability: Easily adjust resources based on demand.
Infrastructure as a Service (IaaS)
IaaS offers virtualized computing resources over the internet. Benefits are:
- Flexibility: Scale resources up or down as needed.
- Control: Full control over the infrastructure.
