What are Saas, Paas, IaaS in cloud computing?

Answer 1

SaaS, it’s a ready app you just open it, like OneDrive, you don’t care about the servers or infrastructure, it’s updated by Microsoft, you only manage the files, it’s ready-made software.

PaaS, it’s like when youare a developer and you want to build an app, you write the code you want, but here you need programming tool,s database, backend service, so here you don’t care about the service of the infrastructure,e also, you just write the code

IaaS, it’s like when you rent virtual servers from a provider, so here you can install whatever you want on the server, you don’t care about the physical infrastructure
