Cloud computing is an on demand availability of cloud system resources such as data storage and computing power without direct active management by the user. The word cloud is used as a metaphor for internet and a standardized cloud like shape was used to denote a network on schematic’s. [1] Cloud is about where you compute, not how you compute. Here, we will discuss about difference between and On-premises and Cloud-based computing, Scalability, server storage with cloud service providers, data security, maintenance in terms of infrastructure as well as cost efficiency. It is described as the delivery of on-demand services over the internet works on “pay-as-you-go” basis. Cloud computing has two type of models:
• deployment model:
public cloud
private cloud
hybrid cloud

• Service model:
infrastructure as a service
platform as a service
software as a service

Cloud computing service models are hassle-free. The most popular cloud computing models AWS, Microsoft’s azure, Google cloud platform are as discussed below. SLAs, instances, container, Kubernetes, Regions, storage are all important factors also discussed in this paper. How cloud providers provide services over the cloud and what are the importance of those services in the modern day infrastructure. The data usage has been discussed providing a large dependency in processing the programs. The future introduction is also mentioned giving new research aspects to the field of cloud computing.
