Systems and methods for performing fast failovers

摘要

A computer-implemented method for performing fast failovers may include 1) identifying an application to fail over from a first computing system to a second computing system, 2) identifying a first component of the application to fail over, the first component depending on a second component of the application and a third component of the application, the second component and third component being mutually independent, and 3) failing the application over from the first computing system to the second computing system by, based on a determination that the second component and third component are mutually independent, (i) taking the second component offline on the first computing system after taking the first component offline on the first computing system and (ii) taking the third component offline on the first computing system while bringing the second component online on the second computing system. Various other methods, systems, and computer-readable media are also disclosed.

1. A computer-implemented method for performing fast failovers, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising:
identifying an application to fail over from a first computing system to a second computing system; identifying a first component of the application to fail over, the first component depending on a second component of the application and a third component of the application, the second component and third component being mutually independent; failing the application over from the first computing system to the second computing system by, based on a determination that the second component and third component are mutually independent:
taking the first component offline on the first computing system before taking the second component offline on the first computing system;taking the second component offline on the first computing system after taking the first component offline on the first computing system;taking the third component offline on the first computing system while bringing the second component online on the second computing system;bringing the first component online on the second computing system after bringing the third component online on the second computing system.
