Today’s organizations are moving towards ‘cloud first’ approach with high intensity and continuous effort. Cloud enables organizations to be more agile, innovative by providing options to pay only for infrastructure and software based on consumption. Organizations can move to digital quickly, if they adopt cloud only approach. There are different cloud services available with multiple cloud service providers and most widely used cloud service types are Iaas, Paas and Saas.

Infrastructure as a Service (IaaS):This is the foundation model of the cloud services, where cloud service provider provides servers, storage, network and physical data center just like on-prem data centers.

Some of prominent providers in this category are Amazon EC2, Microsoft Azure, Google cloud platform etc..

Platform as a Service (PaaS):This model runs on top of IaaS. PaaS cloud suppliers  provides both software and infrastructure components like database, middleware and operating systems, that are used  to develop and test applications. This is used extensively by the developers to build applications to provide business services to the end users.

Some of prominent providers in this category are salesforce, Microsoft Azure, SAP, oracle cloud etc..

Software as a Service (SaaS):This model includes both IaaS and PaaS. SaaS cloud supplier provides software as a pay-per-use model. SaaS provides greater flexibility to end users  by enabling users to access applications directly over internet without thinking about underlying  hardware and software components.

Some of prominent providers in this category are Microsoft Azure office 365, Amadeus reservation system etc..
