Cloud computing isn't simply a catchphrase in today's digitally first society; it's the foundation of contemporary company operations. The cloud makes speed, size, and cost-effectiveness possible for everyone from start-ups releasing mobile apps to multinational corporations overseeing operations worldwide.
However, "the cloud" isn't a universally applicable answer. Different kinds of cloud services are available, depending on what you're building and how much control you desire. Let's dissect them.
1. Infrastructure as a Service (IaaS)
IaaS can be thought of as renting the digital project's base. You can use networking, storage, and servers without actually owning any gear.
What User Manages:
Operating systems
Applications
Runtime and middleware
What the Provider Manages:
Physical servers and hardware
Networking components
Data centres and power
Use Cases:
Hosting virtual machines
Setting up custom environments
Temporary computing needs (e.g., data analysis jobs)
Examples:
Amazon EC2 (part of AWS)
Microsoft Azure Virtual Machines
Google Compute Engine
Ideal for: Developers and system administrators who want flexibility without managing hardware.
2. Platform as a Service (PaaS):
PaaS allows you to concentrate on developing code rather than server configuration. Everything else, including infrastructure, scalability, and runtime, is handled by the platform.
What User Manages:
Your application code
Data and configurations
What the Provider Manages:
Operating system
Development tools and libraries
Infrastructure and scaling
Use Cases:
Rapid app development and deployment
Building microservices
Continuous integration and delivery (CI/CD)
Examples:
Google App Engine
Heroku
Microsoft Azure App Services
Ideal for: Developers who want to build applications quickly without worrying about backend setup.
3. Software as a Service(SaaS):
SaaS is what most people use on a daily basis. It is fully working software that is hosted and managed by a provider and accessible through a browser or app.
What User manages:
User-specific settings and data
What the Provider Manages:
The entire application stack—from servers to the interface
Use Cases:
Email and collaboration tools
Project management software
CRM and accounting platforms
Examples:
Gmail
Microsoft 365
Salesforce
Canva
Ideal for: End-users or businesses who want to use powerful software without installing or maintaining it.

What Should You Pick?
- Choose Infrastructure as a Service (IaaS) if you require total control over your environment.
- Select PaaS if you wish to concentrate just on development.
- SaaS is your friend if all you need to do is use an app to get started quickly.
