- It can be also be managed internally or by a third party provider. PART A Question 4 : Compare Iaas, Paas, Saas with examples. Answer : 1) Iaas, which is Infrastructure as a service which provides
- Provide Virtualized computing resources, such as servers, storage and networking.
-
In this case the Users manage the infrastructure, while the Provider manages the underling hardware such as : Amazon web services (AWS),Microsoft AZure, Google cloud platform. The User manage App and OS.
2) Paas, Which is Platform as a service.
-Provides a Complete platform for developing, running, and managing applications you don't need to be maintaining or building an infrastructure Example are Heroku, Google App Engine, Microsoft AZure Application service. The User manage code.
3) Saas, which is Software as a Service. It is a provides and also manage software application that are accessible over the internet, eliminating the need for local installation and maintenance.
-Users access the application through a web browser or mobile app. Example Salesforce, microsoft office 365,Google workspace.
