The following chapter will equip you with the easy means to help you identify, fix, and survive failures. There are two types of failures that may occur in apps using cloud services: enduring failures which are those that require handling and intervention either from administrators or programs, and transient errors which are those that are moments of service interruptions such as network issues. By understanding the monitoring and telemetry tools offered by Azure, you will be able to detect errors and perform a deep root-cause analysis on different issues.
