SaaS, PaaS and IaaS are the three primary cloud service models that form the foundation of modern cloud computing. Understanding these models is essential for Salesforce professionals because Salesforce operates primarily as a Software as a Service (SaaS) platform while also providing Platform as a Service (PaaS) capabilities for developers.
These cloud service models define how computing resources, software applications, and development platforms are delivered to businesses through the internet. Organizations choose different cloud service models based on their technical requirements, budget, scalability needs, and level of control desired over their infrastructure.
Understanding SaaS, PaaS and IaaS helps Salesforce Administrators, Developers, Consultants, and Architects understand where Salesforce fits within the cloud computing ecosystem.
Cloud service models define the level of responsibility shared between cloud providers and customers.
The three major service models are:
Each model offers different levels of control, flexibility, and management.
Software as a Service (SaaS) is a cloud computing model where software applications are delivered over the internet. Users access the application through a web browser without installing or maintaining software on their local systems.
The cloud provider manages:
Users simply log in and start using the application.
Popular SaaS applications include:
Applications can be accessed from anywhere with an internet connection.
Software updates are handled by the provider.
No need for expensive hardware or software installations.
Organizations can add users and resources easily.
Businesses can start using the software immediately.
Salesforce is one of the best examples of SaaS.
Users can:
Without worrying about infrastructure management.
Platform as a Service (PaaS) provides a development platform where developers can build, test, deploy, and manage applications without managing underlying infrastructure.
The cloud provider manages:
Developers focus only on creating applications.
Popular PaaS platforms include:
Developers focus on coding instead of infrastructure.
Infrastructure management is handled automatically.
Organizations avoid investing in hardware and maintenance.
Development teams can work together efficiently.
Applications can scale automatically as demand increases.
Salesforce provides PaaS capabilities through the Salesforce Platform.
Developers can:
All without managing servers or infrastructure.
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet.
Customers receive:
Customers manage:
The cloud provider manages physical infrastructure.
Popular IaaS providers include:
Organizations have complete control over applications and operating systems.
Resources can be adjusted based on business needs.
No need to purchase physical servers.
Cloud providers offer backup and recovery solutions.
Infrastructure can grow as business demands increase.

Consider a company launching a customer management application.
The company purchases Salesforce CRM and starts using it immediately.
Developers use Salesforce Platform to build a custom CRM application.
The company rents virtual servers from AWS and builds the entire application from scratch.
Each approach offers different levels of flexibility and responsibility.
Understanding these cloud service models helps professionals:
These concepts are frequently covered in Salesforce Administrator, Platform Developer, and Architect certification exams.
Salesforce offers both SaaS and PaaS capabilities.
This combination makes Salesforce one of the most powerful cloud platforms available today.
SaaS, PaaS and IaaS are the three major cloud service models used by organizations worldwide. SaaS delivers ready-to-use software applications, PaaS provides development platforms for building applications, and IaaS offers virtual infrastructure resources. Salesforce operates as both a SaaS and PaaS platform, making these concepts essential for every Salesforce professional to understand.
SaaS stands for Software as a Service.
PaaS stands for Platform as a Service.
IaaS stands for Infrastructure as a Service.
Salesforce is both SaaS and PaaS. It provides CRM software as SaaS and application development capabilities as PaaS.
SaaS is generally the easiest because users only need to access the application through a browser.
PaaS allows developers to build custom applications, automate business processes, and extend Salesforce functionality without managing infrastructure.
