Role of API

APIs play a vital role in cloud computing due to the increasing dependence of technology on clouds such as virtualization, service-oriented architecture, grid computing, and many more. Some of its roles are listed below:

  • It provides a high level of compatibility to multi-cloud integration to integrate data across different cloud providers such as GCP, AWS, Azure and many more
  • It helps in the development of applications and services for the cloud platform.
  • APIs contribute to the rapid cloud access and ensure compliance as well as system integration and application interoperability on the cloud.

Cloud API

The capability to elevate cloud practices and cross-cloud compatibility have led to the development of cloud API. These API’s help system administrators to integrate applications and other workloads to the cloud.

  • Where SOAP is a simple object access protocol, which is designed as a web communication protocol that supports XML data format to follow standard messaging structures, encoding rules and align procedure request
  • While Rest is Representational State Transfer protocol that relies on simple URL for web access and uses four different HTTP verbs such as GET, POST, PUT, and DELETE to perform tasks.
  • The cross-platform and cloud API give the user the ability to access cloud resources not only from their primary cloud provider but also from others. This saves development efforts and time as enterprises can access required cloud resources from other cloud providers as well.
  1. PaaS API– Platform as a service API is developed to provide easy access and operation of a cloud environment by integrating databases, website data, and storage, which results in the finest application development.
  2. IaaS API -infrastructure as a service API manages specific cloud components such as the provision of cloud resources, VM workload, and network configurations.
  3. SaaS API -Software as a service API provides connectivity to applications with cloud infrastructure that gives application extensions for your cloud environment.
  4. Cloud service provider /cross-platform API– As most of the tenants are not confined to a single cloud provider or platform, which has introduced the need for better cross-platform compatibility. Hence, cross-platform APIs allow the cloud to renters the ability to approach their primary cloud service provider as well as others. This will save time and development efforts as resources and workloads are accessible by the organizations from different cloud providers.
  • Amazon Web Services API
  • OpenStack API
  • VMware vCloud API


APIs have become a catalyst for business growth. Major cloud providers offer APIs to connect their services so that they can increase their gaze to involve third-party interfaces for providing outstanding services to their users. APIs have become a gateway to all the distributed data with cloud applications, services, and storage for diverse platforms such as retail banking, communication, and content, leisure, entertainment, e-commerce, and cloud services. Cloud APIs have achieved better cloud flexibility and will continue to grow as the organizations pursue to find more active ways to connect their environments.
