What’s the difference between SaaS, IaaS, and PaaS? Let’s use an analogy: food. SaaS is like a restaurant: you just tell the waiter what food you want, and they’ll bring it to you. IaaS is like renting a kitchen: you have the space, but you have to bring your own ingredients and utensils and cook the food yourself. PaaS sits in between SaaS and IaaS: you give someone your ingredients and recipe, and they’ll prepare the food for you.
