PaaS vs. IaaS vs. SaaS

To understand PaaS in the context of other cloud models, it is important to differentiate between PaaS, IaaS (Infrastructure as a Service), and SaaS (Software as a Service):

IaaS (Infrastructure as a Service): IaaS provides virtualized computing resources over the internet, including servers, storage, and networking. In IaaS, users are responsible for managing the operating system, middleware, and applications. Examples include Amazon Web Services (AWS) EC2 and Microsoft Azure Virtual Machines. IaaS offers more control over infrastructure but requires more management compared to PaaS.

PaaS (Platform as a Service): PaaS abstracts infrastructure management and provides a platform to develop and run applications, which can be optimized by Mastering Docker Entrypoint for efficient container management and deployment. Users focus on application logic, while the platform handles servers, storage, and networking. Examples include Google App Engine, Microsoft Azure App Service, and Heroku.

SaaS (Software as a Service): SaaS delivers fully functional software applications over the internet. Users do not have to manage or maintain anything other than the user interface. SaaS applications are ready to use, and all underlying infrastructure is managed by the provider. Examples include Google Workspace, Salesforce, and Dropbox.

Key Difference: The main difference is in the level of control and responsibility:

• IaaS gives users the most control over infrastructure but requires managing more components.
• PaaS focuses on application development and provides a platform where the infrastructure and some middleware are abstracted.
• SaaS delivers ready-to-use software with no user management responsibilities, other than user access.
