What Is A Cloud Application?
A Cloud application is a software program where the application’s data storage and logic reside on remote servers and accessed through the Internet. Cloud apps employ the resources of distributed networks of servers, such as the cloud, to deliver data and functionality to users.
Cloud apps came into reality in the 1960s, and cloud-based applications have evolved with the rise of the internet and advancements in virtual technology. Salesforce is one of the early inventions of SaaS, whereas Amazon Web Services developed Elastic Compute Cloud in 2006 to mark a milestone in IaaS.
A cloud-friendly application is a traditional application that has been adapted over time. This application cannot be fully efficient but can run on cloud infrastructure.
The cloud-ready application is modified and designed with cloud deployment in mind. This application has cloud-specific features such as flexibility but is not a cloud-native application.
The cloud-native application is designed especially for the cloud environment. Cloud-native apps have cloud-like technologies and architectural patterns such as containers, DevOps, and microservices.
How Does a Cloud Application Work?
Cloud apps consist of a multi-layered architecture such as the client layer, application layer, and data layer. The first layer, the client layer, is the user interaction place, such as a web browser, mobile app, or desktop application. The second layer is the application layer, where the layer hosts the logic of the app, receives requests from the users, processes them, and interacts with the data layer. The third layer is the data layer, where the application’s data is managed and stored. The data layer handles updates, storage, and data retrieval and includes databases and caching mechanisms.
The data storage and processing in remote data centers work through storage, processing, and remote access. Cloud developers store the data in storage, such as databases and distributed file systems. The servers in the data center process the data from the data layer and allow large-scale data processing. The cloud developers manage the data via remote access and underlying infrastructure.
Cloud applications do not permanently reside on local devices, which offers many benefits such as storage space, portability, and no installation. Cloud apps provide limited offline functionality, which means the basic functionality of cloud apps needs an internet connection. Online updates are updated automatically on the cloud apps, which minimizes disruption.
