Description: Availability monitoring is the process of checking whether a service or application is operational and accessible. This process is fundamental in the realm of cloud observability, as it allows organizations to ensure that their systems and applications are functioning correctly and are accessible to end users. Through various tools and techniques, interruptions, latencies, or any anomalies affecting service availability can be detected. Key features of availability monitoring include the ability to perform periodic checks, generate real-time alerts for failures, and collect metrics that allow for performance analysis over time. The relevance of this monitoring lies in its direct impact on user experience and company reputation, as an inoperative service can lead to economic and trust losses. In a distributed environment, where services are accessible from anywhere, availability monitoring becomes an essential practice to ensure that applications and services are always within reach of users.
