Cloud computing models has brought on great digital transformation. Many people believe that cloud computing is a simple change of on-premises structures for the use of cloud servers.
However, cloud offers a multitude of possibilities and services. Thus, there are still many questions related to which model to choose before effectively moving to a cloud model. In this post, we’ll present the main models and help you in your choice.
Before we start talking about Cloud models, let’s take a step back and understand what “on-premises” means.
On-premises refers to all the infrastructure that needs to be managed in a company. This includes servers, applications, network, storage, virtualization etc. — that is, it is not a cloud model.
IaaS (Infrastructure as a Service)
IaaS is the cloud computing model closest to on-premises infrastructure. It is a pay as you go model. In it, the public cloud provider offers infrastructure services for companies.
This model is widely used when a company has an on-premises application and they want to get it into the cloud with the least possible effort. However, it is worth noting that, due to the fact that it is very close to on-premises infrastructure, you still need to manage a lot of things in this model, such as operating systems, middleware, runtimes, updates etc.
PaaS (Platform as a Service)
PaaS goes beyond on-premise infrastructure. In this model, the public cloud provider manages not only hardware, but also software. This allows the company receiving the service to focus only on the development of the application.
PaaS is widely used when you are going to launch a fully Cloud-native application or when you want a faster time-to-market.
SaaS (Software as a Service)
SaaS is a cloud computing model in which the entire application is in the cloud and you only “rent” it.
In this model, you do not manage or implement anything, all this is done by a provider. A good example of a SaaS application is Office365.
The following is a table that explains the 3 models in question, as well as on-premises option.
Currently, cloud computing provides a multitude of options for a company to achieve its goals. The big challenge is choosing the one that best suits your business.
