Public cloud services allow your business to increase its IT capabilities at a lower cost and at a higher rate than if you were to maintain your own infrastructure. The infrastructure as a service model rids you of the need to buy more hardware as your business grows and you can increase or decrease the amount of resources you’re using according to your needs. Maintenance costs are the responsibility of your IaaS provider. Your data will also be much more disaster-proof in the public cloud due to the backup services offered by providers.

It is also true that public cloud infrastructure is not seen as suitable for certain types of sensitive data such as medical records or banking information.
