Known to be implemented in a short time with ready infrastructure availability, Public Cloud Services also takes the burden off on-site hardware and software expenses. It enables scalability depending on demand requirements and flexibility to choose from a range of services including Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). The large number of servers and networks that service providers offer ensures reliability in case of specific failures. And the pay-as-you-go option delivers cost efficiency. Availability of services over the internet provides remote access opportunities and multiple location coordination.
