Cloud computing has transformed how businesses, especially tech startups, handle their IT infrastructure.

Instead of maintaining costly on-premises hardware, companies can now rent computing power, storage, and other services from cloud providers. This shift offers flexibility, scalability, and often cost savings.

So, what are the main types of cloud services and how do you know which is right for your startup?

The main types of cloud services are:

1. Infrastructure as a Service (IaaS): Provides on-demand computing resources over the internet. Examples include virtual machines, storage, and networking.

2. Platform as a Service (PaaS): Offers a platform for developers to build, run, and manage applications without the complexity of maintaining the underlying infrastructure.

3. Software as a Service (SaaS): Delivers software applications that customers can use over the internet. They are usually managed and maintained by the provider.

4. Serverless Computing: Offers ways to develop applications as straightforward, event-triggered processes, which eliminates the need to scale or manage any infrastructure.

Major cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform offer all these service types, along with specialized tools for data analytics, artificial intelligence, and more.
