Definition
SaaS, or Software as a Service, in Portuguese, it is a model of software distribution and licensing in which applications are centrally hosted and made available to users via the internet, usually through a web browser
Main Concept
In the SaaS model, instead of buying and installing the software on individual computers or local servers, users access the application via the internet, usually paying a recurring subscription
Key Features
1. Cloud-Based Access
– Users can access the software from anywhere with an internet connection
– There is no need for local installation or hardware maintenance
2. Signature Model
– Recurring payments (monthly, annual) instead of a large upfront expense
– Flexibility to scale up or down usage as needed
3. Automatic Updates
– The service provider manages all updates and patches
– Users always have access to the latest version of the software
4. Multi-tenancy
– A single instance of the software serves multiple clients
– Efficient in terms of resources and costs for the provider
5. Personalization and Integration
– Many SaaS services offer customization options
– APIs available for integration with other systems
