Description: The term ‘on-demand’ refers to systems or resources that are activated or utilized only when needed, thereby optimizing resource use and improving efficiency. This approach is fundamental in modern computing, where scalability and flexibility are essential. Instead of keeping resources active continuously, on-demand systems allow resources to be provisioned and deprovisioned dynamically, adapting to the needs of the user or application in real-time. This not only reduces operational costs but also enhances performance by ensuring that resources are used optimally. In the context of technology, this concept applies in various areas, such as cloud computing, where services are offered based on user demand, as well as in media streaming and software applications, where content and functionalities are delivered based on current user needs. The implementation of on-demand systems can include the use of containers, microservices, and serverless architectures, enabling developers to create more efficient and scalable applications.
