Observability, Monitoring, and Application Management

Monitoring and observability are crucial aspects of managing and maintaining the health, performance, and reliability of modern applications. In microservices-oriented applications, with multiple instances of different services running at the same time to deliver a solution, observability and monitoring help in understanding the interactions between these services and identifying issues.

Monitoring plays a crucial role in large environments, enabling resource utilization and performance metrics to be tracked. This, in turn, facilitates dynamically scaling resources to effectively meet the demands of the system. This is especially useful in cloud computing environments, where you pay for the resources used and where you can adapt your application resources to the real demands of your users. Without monitoring, how do you know if your application is running at 100% CPU and the response time is so slow that your users abandon your...
