Description: Application dependency mapping is a critical process that involves identifying and documenting the interrelationships between various applications and services within a technological infrastructure. This process allows organizations to understand how applications depend on one another, which is essential for effective IT infrastructure management. By mapping these dependencies, businesses can identify critical points that could impact business continuity in the event of failures or disasters. Additionally, this mapping facilitates the planning of disaster recovery strategies, as it allows prioritization of which applications and services should be restored first. It is also fundamental for ensuring quality of service, as it helps identify bottlenecks and optimize application performance. In an increasingly complex technological environment, including cloud-based systems, dependency mapping becomes an indispensable tool for risk management and continuous improvement of IT services.
