Cloud service models are basically ways to use cloud computing without needing to own a lot of hardware or worry about stuff like maintenance there are three main types of cloud service models and they are really popular with businesses and individuals the first one is called infrastructure as a service or ias this model lets you rent virtual machines storage and networks from cloud providers like amazon web services or microsoft azure it’s like renting a server but you don’t have to buy any physical hardware you can just spin up virtual machines whenever you need them and pay for what you use so if you need more power during busy times you can just get more and then scale down when you don’t need it anymore

the second model is called platform as a service or pas this one gives you more than just infrastructure it provides a platform where you can develop run and manage applications without dealing with the underlying hardware the cloud provider takes care of all the boring stuff like servers databases and networking you can focus on building your app and making it work with pas it’s like having a full toolbox ready for you to create stuff you don’t have to worry about setting everything up from scratch

then there’s software as a service or sas this is the one that most people are familiar with it’s like using applications online without needing to install anything on your computer think of apps like google drive or office 365 these services are hosted in the cloud and you access them through a web browser you don’t need to worry about updates or patches because the provider takes care of all that for you you just log in and use it it’s super convenient

so in a nutshell ias gives you the basic building blocks for computing pas provides the platform for development and sas offers ready to use software all these models help people and businesses save time and money while making it easier to use technology without the hassle of managing physical resources
