Software-Defined Technologies: Transforming the Value Stream

  • Hypervisors — A hypervisor is an operating system that runs virtual machines, like VMWare ESXi or Microsoft Hyper-V. It runs directly on the physical machine, abstracting and distributing the hardware resources to any number of virtual machines. This has undoubtedly been one of the largest and most impactful advances in IT in the last 20 years, ushering in the era of point and click server deployment and changing the way we manage and deliver IT services.
  • Software-defined Networking (SDN) — Traditionally, operating a network means managing lower level infrastructure that allows devices to connect, communicate with each other, and figure out where to send their packets. These switching devices — called “layer 2 devices” — each need to maintain their own state and configuration information, and make decisions about how to route packets based only on limited, locally available information. SDN abstracts layer 2 networking, and is the ‘secret sauce’ behind cloud computing — a critical functionality for all public cloud services including AWS, Azure and OpenStack-based providers. It allows the service provider to centralize routing and switching, and provides the orchestration capability required for large-scale multi-tenancy i.e. the ability to create and manage millions of logically isolated, secure networks.
  • Network-function virtualization (NFV) — Building upon SDN, NFV allows services like load balancers, firewalls, IDS, accelerators, and CDNs to be deployed and configured quickly and easily. Without NFV, to operate infrastructure at scale you would need a lot capital investment and an experienced team of highly specialized network engineers. NFV makes it easy to deploy, secure and manage these functions without having to understand the complexities underneath the hood.
