Server Virtualization

This term refers to the separation of the logical elements of a server and their function, CPU and memory, physical storage and the intervening input/output (I/O) paths from physical instantiation, and the ability to manage the associations between these elements to provide the basic list of capabilities through a nondisruptive process.

    REPORT: The Software-Defined Data Center Comes Of Age

    October 30, 2017Richard Fichera, Chris Gardner

    Traditional data center thinking has ended. Better automation tools, container abstractions, software-defined networks (SDNs), and composable infrastructure have ushered in unprecedented abstraction, yielding the software-defined data center (SDDC). The impact of the SDDC is immense, offering an opportunity to integrate legacy architectures, cloud, and workload-centric architectures into a single automation domain. This report helps infrastructure and operations (I&O) professionals understand this vision and defines the current state, opportunity, and emerging vendor landscape of the SDDC. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.

    REPORT: Rumors Of VMware's Demise Are Greatly Exaggerated

    VMware Faces Great Challenges But Keeps Delivering Growth, Defying Its Critics

    July 12, 2017 Chris Gardner, Dave Bartoletti, Andre Kindness, Richard Fichera

    VMware, for years one of Silicon Valley's darlings, has struggled to find its place in the new world of cloud computing. Skepticism over its long-term viability continues because of unprecedented challenges, and some execution and strategic missteps. However, it keeps delivering growth and sound financial performance, contradicting critics. Part of this is due to the growing maturation of the software-defined data center (SDDC) and the increasing popularity of infrastructure-as-code (IaC). This report helps infrastructure and operations (I&O) professionals understand the issues affecting VMware and its pundit-defying staying power.

    REPORT: Vendor Landscape: Software-Defined Data Centers

    The SDDC Is Still A Work In Progress, But Progress Is Swift

    September 1, 2016Robert Stroud, Richard Fichera

    To meet needs arising from the unprecedented acceleration of the digital business, infrastructure and operations (I&O) professionals are shifting their attention from physical infrastructure to software abstractions of the operational stack: infrastructure and applications together. Software models, automation, and hardware all come together to effectively scale. As a single product, the software-defined data center (SDDC) has proven elusive, but as an aspirational goal, it's shaping the way that customers consume infrastructure. In this report, we highlight the multiple vendors that are stepping up to the challenge in different categories.

    REPORT: TechRadar™: BT Infrastructure, Q2 2016

    May 9, 2016 Andre Kindness, Robert Stroud, J. P. Gownder, Michele Pelino, Richard Fichera, Dave Bartoletti

    Software has turned the infrastructure world upside down. Hardware speeds and feeds no longer dominate infrastructure and operations (I&O) professionals' criteria; they know that the fastest packet-processing chip or largest disk capacity won't deliver on the business technology (BT) agenda. I&O professionals now adopt technologies, such as infrastructure-as-code or interaction technologies, that can help with business' digital transformation — and the market has responded. Forrester identified and investigated 13 of the most important BT infrastructure technologies that help make this digital transformation happen. This TechRadar report defines the current state, business value, and long-term prospects for each technology.

    REPORT: Brief: VMworld 2015 Reveals A Disruptor In Transition

    VMware Woos Cloud-Native Developers In Its Quest To Overcome Its Innovator's Dilemma

    October 1, 2015 Lauren E. Nelson, Dave Bartoletti, Charlie Dai, David K. Johnson, Andre Kindness, Christopher Mines

    VMware recently revealed the direction that it's heading at its annual VMworld conference. In 2013, VMware announced its pursuit of three complementary product strategies for the BT agenda: 1) extension of virtualization to the fully software-defined data center; 2) launch of a public cloud service; and 3) a richer end user computing suite. These strategies were aimed at helping VMware's core infrastructure and operations (I&O) professional customers and its new targets: developers, business groups, and C-level executives. The new Photon Platform, vSphere Integrated Containers, and the NSX network overlay VMware unveiled at VMworld 2015 are concrete steps toward winning new champions, but VMware isn't there yet.
