Cloud software development: a brief introduction

What does it mean to develop software in the cloud? The key concept is that cloud-based applications are hosted on remote servers rather than on users' local devices. This allows access from any device connected to the Internet, unlike traditional applications that are limited to the device on which they are installed.

Taking the older programs offered by Microsoft Office and Google Workspace, for example, both provide a suite of productivity applications, including text editors, presentations and spreadsheets. However, while Microsoft Office apps must be installed locally on user devices, Google Workspace apps operate as cloud-based applications, allowing documents to be accessed and edited directly through the web browser.

In practice, this means that the documents and associated data are stored on remote servers and can be accessed from anywhere with an internet connection. While some features may be available offline with cloud-based apps, an internet connection is often required to take full advantage of their real-time collaboration and synchronization capabilities.

This shift to cloud computing is evident in a variety of applications and services, including Microsoft 365, Adobe Creative Cloud, and Jira Cloud that offer advanced, vertical functionality for their purposes through cloud-based access.

Characteristics of an application developed in the cloud

In addition to the accessibility of a cloud service mentioned earlier, there are five other key characteristics in the context of cloud software development.

1. Scalability: in the context of cloud software development, scalability is a fundamental advantage.

This allows you to manage sudden load peaks, such as in the case of a promotion or a major event, without having to invest in additional hardware. The flexibility offered by cloud computing is essential to adapt quickly to changing market demands.
   ‍
2. Shared resources: a distinctive feature of cloud computing is the sharing of resources. This model allows users to take advantage of cloud infrastructure efficiently, while dividing costs and computational capacity with others. However, it's important to ensure asset isolation to maintain data security and privacy. Cloud environments are designed to ensure that each user's resources are protected and accessible only by those with authorization.
   ‍
3. Automatic updates: in cloud software development, automatic updates are a crucial feature to ensure that the performance and security of the application are maintained over time. Cloud service providers actively manage the underlying infrastructure and regularly apply security patches and performance improvements without interrupting the service. This allows developers to focus on developing the application rather than managing the underlying infrastructure.
   ‍
4. Subscription-based or pay-as-you-go model: represents a flexible financial approach that offers users the option to pay only for the resources they use on a monthly basis or based on actual usage. This model contrasts with the traditional approach of buying software licenses in advance. The key to this model is its adaptability to evolving business needs, allowing companies to scale resources based on business growth or to reduce them in periods of less activity. This approach reduces the risk of overinvestment in unused resources and allows for more precise long-term cost management.
   ‍
5. Reliability: cloud service providers assume responsibility for storing and managing application data. This involves the need to implement robust backup mechanisms and automated monitoring tools to ensure business continuity and data security. Cloud service providers invest in highly reliable and available infrastructures to ensure that management applications are always accessible and that data is protected from loss or damage events. In this way, management software developers can focus on developing application functionality without having to worry about managing and maintaining the underlying infrastructure.
