Platform as a Service (PaaS)
PaaS provides a complete environment for software development and deployment.
Benefits:
- Faster development process
- Reduced infrastructure management
- Simplified deployment
Software as a Service (SaaS)
SaaS delivers software applications through web browsers.
Examples include:
- Email services
- Collaboration tools
- Customer management systems
- Project management software
Benefits:
- Easy accessibility
- Lower costs
- Automatic updates
