    An Introduction to Live Migration in NFV Deployment

    This article is the first of two on live migration in NFV Deployment. Live migration is a generic feature that is important in all cloud environments including Network Functions Virtualization (NFV) applications. This post covers likely NFV use cases for live migration, the type of loads that are likely to be executed on compute nodes, an overview of live migration, and some common issues to consider with focus on LTE Evolved Packet Core (EPC). This article uses VNF (Virtual Network Function) and  guest interchangeably. VNF essentially is a guest equivalent to a hardware Network Element. The Various Uses of Live Migration Here are some common live migration uses: Load Balancing – Migrating VMs between compute nodes to balance the load Hardware Maintenance – Routine maintenance, such as hardware upgrades, or  IPMI events such as thermal readings from sensors that indicate the node may fail soon for example cooling issues. This […]
