To fully understand how Salesforce operates, you need to grasp the concept of Cloud Computing and the different types of Cloud Services. In this tutorial, we’ll explain these services and how Salesforce fits into the cloud landscape.
What Are Cloud Services?
Cloud services deliver computing resources (like servers, databases, storage, and software) over the internet. Instead of managing physical infrastructure, users can access services on demand.
Types of Cloud Services
1. Infrastructure as a Service (IaaS)
- Provides basic computing resources like virtual machines, storage, and networking
- Users manage OS, apps, and middleware
- Examples: Amazon EC2, Microsoft Azure, Google Compute Engine
2. Platform as a Service (PaaS)
- Provides a platform for building, testing, and deploying applications
- Developers focus only on code; infrastructure is managed by the provider
- Examples: Heroku (owned by Salesforce), Google App Engine, Microsoft Azure App Service
3. Software as a Service (SaaS)
- Complete software solutions delivered over the internet
- No need for installation or maintenance
- Examples: Salesforce CRM, Gmail, Dropbox
Where Does Salesforce Fit?
Salesforce primarily operates as a SaaS provider. Users access Salesforce CRM through a web browser without worrying about servers, updates, or maintenance.
Salesforce also offers PaaS capabilities through:
- Force.com – For building apps on Salesforce’s infrastructure
- Heroku – For scalable app hosting
- Salesforce DX – For managing and deploying code in the cloud
Advantages of Cloud Services
- Cost Efficiency – Pay-as-you-go model
- Scalability – Scale resources up/down based on demand
- Accessibility – Access from any device, anywhere
- Security – Centralized and managed by cloud providers
- Speed & Agility – Rapid development and deployment
