What is cloud computing?
Cloud computing refers to the delivery of IT resources on-demand over the internet where the pricing structure follows a pay-as-you-go model. This method eliminates the need for organizations to buy and manage physical data centers and other servers. They can instead access the technology services like storage, computing power, and databases from cloud providers on a need basis.
Some popular cloud providers are Amazon Web Services (AWS), Microsoft Azure, Google Cloud, IBM Cloud, SAP, Oracle, and many more. Cloud computing enhances the reusability of the various IT resources for purposes such as developing or hosting applications.
Types of cloud computing

Companies can outsource storage, data center space, servers, and other cloud networking components that are connected through the internet and offer the same capabilities as the on-premises infrastructure.

In this model, the service provider builds the servers, storage, firewalls, security, and also the physical data center. Amazon EC2, Google Cloud Platform, Rackspace, and Microsoft Azure are a few prominent IaaS service providers.

The environment facilitates cloud users to host data sets and also build the necessary hardware. Some prominent players that offer PaaS services are CloudBees, Heroku, Microsoft Azure, SAP, and Oracle Cloud.

The users can access various applications through the internet. Microsoft Office 360, Adobe Creative Cloud, Salesforce Marketo, and AppDynamics are the leading SaaS service providers in the current market.
