    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 […]

  • Open Source Wrap Up June 20 – 26, 2015 The Open Container Project is Launched The Linux Foundation has announced the launch of a new industry partnership called the Open Container Project (OCP). In recent years, Docker has led a rapid expansion of Linux containers with their popular platform that has focused on providing a common platform for an incredible range of IT tools.  OCP will continue to build upon this by using code that has been donated by Docker Inc. to create a platform that adheres to the following guidelines: not be bound to higher level constructs such as a particular client or orchestration stack not be tightly associated with any particular commercial vendor or project and be portable across a wide variety of operating systems, hardware, CPU architectures, public clouds, etc. The goal is to set common, minimal standards around container technology, and the project includes companies that […]
