A cloud application, also known as a cloud app, is a software application that runs on a cloud computing platform and is accessed over the internet through a web browser or mobile app. These types of applications are designed to be highly scalable and can be used by a large number of users simultaneously.
Cloud applications can be developed using different cloud services models such as Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).
SaaS cloud applications are fully managed by the cloud provider and are typically accessed through a web browser. Examples include email, customer relationship management, and office productivity software.
PaaS cloud applications are platform-level services that provide a framework for developing and deploying applications. Examples include Google App Engine, AWS Elastic Beanstalk, and Azure App Service.
IaaS cloud applications are infrastructure-level services that provide computing resources such as storage and computing power. Examples include Amazon Elastic Compute Cloud (EC2), Microsoft Azure Virtual Machines, and Google Compute Engine.
Cloud applications have several advantages over traditional, on-premises software, such as easy scalability, high availability, automatic software updates, and the ability to access the application from anywhere with an internet connection.
