SaaS, PaaS y IaaS - Coggle Diagram

- - - - Just as with SaaS and PaaS, there are specific situations when IaaS is most advantageous.
        
        Startups and small companies may prefer IaaS to avoid spending time and money on purchasing and creating hardware and software.
        
        Larger companies may prefer to retain complete control over their applications and infrastructure, but they want to purchase only what they actually consume or need.
