The Advantages:

• We do not need investment and maintaining the infrastructure, platform or application. Stay put for free (for a service which is free) or pay-as far as we use (pay as you go).

The Disadvantages:

• Depends on the quality of internet services we use, if the internet connection dies, we cannot use the service. For that we need to think carefully its internet infrastructure.
• Not all service providers, ensure the security of our data. For that we need to be careful to choose the provider’s Public Cloud. Learn in detail about the profile and the Service Level Agreement of the service provider.
