As cloud computing dominates more and more aspects of the tech world, similar-sounding but confusingly different something-as-a-service acronyms keep piling up. You’ve probably heard of SaaS (Software as a Service), since it applies mostly to cloud services delivered to end users. 

But what about IaaS (Infrastructure as a Service) and PaaS (Platform-as-a-Service)? Even many tech professionals can’t explain the differences without babbling incoherently. 

Fortunately, this new infographic from IaaS provider ProfitBricks does a good job of explaining the differences and who uses which one for what. Enjoy.
