In contrast, a process suffering a total failure can be quickly identified, restarted, or repaired by existing mechanisms, thus limiting the failure impact. 71% of failures are triggered by a specific environment condition, input, or faults in other processes. Developers can also explicitly annotate an operation as @vulnerable.

Working with never-ending streams of data necessitates continuous processing of it, ensuring the system keeps up with the load patterns it is exposed to, and always provides real-time, up-to-date information.
