Description: The underlying infrastructure refers to the technological components and fundamental systems that support applications and services, such as databases and cloud platforms. This infrastructure includes servers, networks, storage, and databases, which work together to provide a robust and scalable environment. In the context of edge computing, the underlying infrastructure extends beyond traditional data centers, enabling data processing closer to the source of generation, which reduces latency and improves efficiency. On the other hand, in microservices architectures, the underlying infrastructure is crucial for the orchestration and management of multiple independent services that communicate with each other. This involves the use of containers, service management tools, and cloud platforms that facilitate the deployment and scalability of applications. The underlying infrastructure not only provides the necessary technical support but also influences the performance, security, and availability of the services offered. In summary, it is an essential component that allows organizations to build and maintain complex and efficient technological systems.
