When designing Network Functions Virtualization (NFV) solutions, some software providers approach the problem of high availability through application-level redundancy schemes (load balancing, check pointing, journaling, etc.). But application-level high availability by itself doesn't achieve the goal of five-nines (99.999%) reliability—the standard set by service providers using traditional network infrastructure based on physical equipment. In this paper, find out how to ensure five-nines availability for services delivered in an NFV implementation.
