The Nexus of Forces is the convergence and mutual reinforcement of social, mobility, cloud and information patterns that drive new business scenarios. Although these forces are innovative and disruptive on their own, together they are revolutionizing business and society, disrupting old business models and creating new leaders. The Nexus is the basis of the technology platform of the future.
16 April 2012
The innovation rate in mobile devices, social software and cloud computing is accelerating faster than the enterprise adaptation rate. IT organizations that fail to adapt to this new reality will lose their relevance in the era of pervasive mobility.
11 April 2012
Public cloud infrastructure as a service (IaaS) stands at a crossroads. In one direction, it will mature and host critical enterprise workloads. In the other direction, its adoption will fizzle and it will remain viable only for noncritical applications. In order to succeed, IaaS and its providers must withstand the scrutiny of IT organizations with a core set of enterprise capabilities necessary to run mission-critical business. In this assessment, Gartner identifies such capabilities and provides measurable criteria for public IaaS customers to evaluate enterprise-grade IaaS providers and solutions.

Cloud computing's on-demand, pay-as-you-go service model is transforming IT from massive, cumbersome, internal cost centers into agile, reactive, external services that are used not merely as business tools, but as the medium by which business is conducted. Unfortunately, marketing hype, unclear return on investment, and difficult risk/benefit analysis continue to hinder cloud adoption. Organizations that best understand cloud computing can take advantage of its strengths and mitigate its risks. In this management initiative, Gartner clarifies the discussion by defining cloud computing and its characteristics, architectural model, benefits, and shortcomings.
1 November 2011
Cloud computing continues to be a rapidly growing, volatile, and immature market that is full of cloud service providers (CSPs) with varying degrees of service types and quality. In 2011, security, liability, licensing, transparency, and provider lock-in were the top cloud issues. Although these issues remain, in 2012, the industry's attitudes toward cloud computing will change.

The flow of messages and content faced by information workers is increasing, but their attention spans remain fixed and limited. Each beneficial new communication and collaboration technology brings along the burden of one more channel that information workers, who are already feeling overloaded, must pay attention to. Accordingly, attention fatigue will be a gating factor for the success of collaboration and communication projects and activities. This overview examines how attention fatigue afflicts businesses and how an Enterprise Attention Management (EAM) strategy improves information worker effectiveness and responsiveness.
24 May 2012
Content mobility is about more than simply ensuring that content is readable on a 2-inch screen. It is about precision content delivery. When users are interacting with content for shorter periods, with a smaller display and more distractions, it is critical to make the most of that limited window of opportunity.
30 April 2012
Enterprise communication is in a golden age where technology is enabling anytime, anywhere and any-device capabilities that easily traverse technological, organizational and geographic boundaries. The time for enterprises to optimize and integrate their communication technologies for greater efficiencies and sustained collaboration at lower costs is now. In order to do so, enterprises need to address the underlying challenges to reach the target state of optimized enterprise communication technologies. Enterprises that maximize their opportunities for people-oriented communications – conversations, information sharing, cooperation and collaboration – will enjoy a distinct advantage in their quest for success.

Mobile unified communications (UC) clients can be a silver bullet. They allow enterprises to effectively address user and business requirements to support anytime-anywhere access to enterprise communications on smartphone and tablet devices. However, for these solutions to realize their full potential, they must be viewed in the context of an enterprise's broader enterprise and communication, collaboration, content and social (3CS) mobile strategies. Enterprises will be challenged by users' expectations in terms of devices, wireless technology and end-to-end experience. In this assessment, Mark Cortner provides an analysis of the user requirements and the challenges related to mobile UC clients.
10 February 2012
Mobility is at the tipping point: When used together in certain work scenarios, smartphones and tablets are on a functional par with desktop PCs and laptops. IT must now give the same level of attention and support to mobile devices as it has lavished on desktop PCs -- learning how users want to employ mobile devices as they collaborate and ensuring that users can perform bread-and-butter tasks with their smartphones and tablets. In this overview, Gartner looks at the impact mobile devices are having on the communication, collaboration, content and social (3CS) space and offers a framework for assessing how and when to use mobile devices.

The modern enterprise exists within a world of information abundance. Applications and business processes generate data at an ever-accelerating rate and in increasingly diverse formats. Semantic Web technologies provide a practical solution for integrating these resources and analyzing them in a way that preserves their original meaning. Linked open data (LOD) is a rich source of data that can augment internal, proprietary information sources to yield insights without the expense of creating the data internally. Together, the Semantic Web and linked data can provide a distinct competitive advantage to the information-intensive enterprise.
14 December 2011
Organizations are struggling to decide which type of mobile application to deliver to their users. The decision often involves a trade-off between delivering a native experience that is rich and interactive or favoring portability that allows them to deliver a more cost-effective solution that targets multiple platforms. But other factors also influence the decision, such as manageability, discoverability, and maintainability. In this Decision Point, Kirk Knoernschild provides a structured decision framework that guides organizations through this decision.

Big data analytics based on Hadoop-MapReduce technologies can help organizations to conquer the dual business intelligence (BI) problem of extreme data size and data diversity, thereby creating the big data warehouse (BDW) -- the BI infrastructure "new kid on the block." A BDW requires organizations to distill many different data types into a hybrid BI infrastructure to enable it to work synergistically with the organization's enterprise data warehouse (EDW). Moreover, a consistent data management infrastructure demands that organizations acquire BDW skills and expertise and then coalesce the BDW with the organization's EDW for a competitive advantage.
2 December 2011
Big data analytics based on Hadoop-MapReduce technology has well-documented potential to reveal new insights and provide significant business value. However, the technologies, programming styles, and analytic methods of big data analytics depart drastically from traditional data warehouse methods and tools. Enterprise data warehouse (EDW) teams and business intelligence (BI) competency centers will need to evolve their team structure, skill set, and methods to successfully harness this relatively young programming framework.
29 August 2011
Analytics are hot. Corporate executives demand deep data analyses that prompt businesspeople to holler for help from IT, who turns to business intelligence (BI) specialists, who direct vendors to deliver complex analytics with pretty interfaces. The cycle repeats: Businesspeople stay stuck in a quagmire of iffy analyses, prompting corporate executives to demand deeper analyses, and so on. To break the cycle, apply behavioral analytics to characterize subtle activities by people, products, and places. In this assessment, Research VP Joseph M. Bugajski explains how to introduce and use behavioral analytics to find more good guys (customers) and bad guys (threats).

Enterprise data. Everywhere. Gartner's field research examined information's tendency to flow to destinations known, unknown, typical and surprising. This research also explored how information security teams attempted to inhibit this sprawl using an array of technical controls, including identity and access management (IAM) and content-based data loss prevention. However, in many cases, sprawl wasn't something to be prevented – it was a requirement for the business: Deliver the right information to the right people right now. This is the story of how field research participants responded to the challenge.

The consumerization of IT has had its greatest impact on mobility. The iPad triggered a monumental shift in the tablet marketplace, which has sparked a consumer-driven revolution. End users continue the push to allow their own devices on the enterprise network. This document outlines how to establish a bring your own device (BYOD) policy and analyzes the issues that may accompany it.
12 April 2012
Securing mobile endpoints (including notebooks, tablets and smartphones) is a requirement for most organizations. The controls needed on the mobile endpoint depend on the information to be stored on the device (if any is to be stored at all), the ownership of the mobile endpoint device and the mobile application architecture. This Decision Point examines the architectural decisions for mobile endpoint controls and shows the relationship between security controls, the mobile application architecture, network connectivity and mobile device management.
3 April 2012
The choices identity teams have for managing and enforcing access control have grown well beyond traditional mandatory and discretionary access control. Rule- and role-based access control, as well as the more recent attribute-based access control, all have a place in an overall authorization strategy. Identity teams also have a choice of where and when they choose to enforce authorization decisions. This Decision Point examines the tools and methods identity teams can use to manage and enforce authorization, and it provides a means for selecting appropriate authorization mechanisms for a given situation.

Organizations are looking for tools and policies to protect their intellectual property and other sensitive information while still making the necessary information available to employees who wish to use the latest and greatest devices to work from locations both inside and outside the organization's facilities. Organizations are trying to understand issues of device ownership, the separation of personal and enterprise applications and data, the risk the new devices bring to the organization, and the costs associated with mobility. This document discusses the results of Gartner's mobility field research project that investigated how enterprises are dealing with mobile devices.
22 January 2012
Handheld devices, such as smartphones and tablets, contain powerful processors, memory, and communications capabilities that make them, in reality, small versions of desktop computers. Handheld devices frequently contain sensitive information, and therefore, they must be protected. In this assessment, Research Director Mario de Boer and Vice President Eric Maiwald compare and analyze the security controls of the most popular handheld-device platforms in an effort to inform enterprises as to how to manage the risks these devices present.
22 January 2012
The consumerization of IT has had its greatest impact on mobility. The introduction of the iPad triggered a revolution in the tablet marketplace. The impact of the smartphone has long been felt, but along with the effect of tablet devices in the workplace, the push is on for better mobility tools. IT still has the responsibility to protect organizational intellectual property and is struggling with bring your own device (BYOD) programs and mobile data management. In addition, IT has a responsibility to improve employee productivity through technological advances.
18 July 2011
Fundamental changes in the work model require a focused process for changing the role of IT security from enforcing controls to providing services that enable organizations to manage their IT-related risk.
11 June 2011
Data handlers rely on contextual information about the data they are handling to make decisions. Today, that information is implicit and tribal in nature. When data moves from one system, department, organization, or country to another, it moves from one context to another. And in moving from one context to another, data leaves behind its handling rules, expectations, norms, and agreements unless something makes all of these things explicit and bundles them with the data before it moves. Better data-handling decisions can be made by labeling data with this contextual information; this is the goal of what Gartner calls relationship context metadata (RCM).
10 February 2012
Anywhere/anytime work patterns have taken hold -- due largely to the Internet, cloud computing, wireless access and smaller device form factors. How IT and business practitioners do their job, along with how they are managed, is changing too. This management horizon of emerging developments will help IT practitioners both prepare for the shift in how work is done in the era of mobility and understand the longer-term implications.
2 February 2012
IT consumerization is erasing barriers that used to prohibit technology experimentation and solution creation by businesspeople. As more of these barriers disappear, citizen developers emerge. Citizen developers are end users who create business applications for consumption by others using corporate-IT-sanctioned development and runtime environments. Previously, "shadow IT" was viewed negatively; now it is increasingly associated with how business gets done. As a result, technical professionals must begin seeing citizen developers as partners in solution development, instead of adversaries. This document by Research VP Mike Rollings discusses the implications of citizen developers and how IT must change to actively support them.
27 December 2011
The appearance of Web 2.0, and later Enterprise 2.0, triggered a renaissance of interest in collaborative technologies. Since then, a number of products and new features within existing products have emerged to leverage this trend. However, products rooted in the 2.0 era are starting to show their age. In this assessment, Research Director Larry Cannell explores how post-2.0 technologies build on the popularity of social networking and smartphones, how they make collaborative environments relevant to a wider audience of workers, and why it is time for IT professionals to rethink their assumptions regarding collaboration within enterprises.
23 December 2011
A recent Gartner research survey has suggested that CIOs reimagine their roles and the role of IT. What about the workforce? What about you? Should practitioners reimagine their roles and their jobs? How would that align with what senior executives are thinking?
1 November 2011
The macro trends of volatility, multiplicity, versatility, and mobility underlie much of Gartner's IT1 coverage in 2012.
9 June 2011
Many IT organizations adopt new practices to improve portfolio management, enterprise architecture, software development life cycles, and other individual IT competencies. However, as staff members implement these changes, they naively make changes to their own competency silos but avoid addressing cross-competency changes. This ultimately limits effectiveness. In this management initiative document, Research VP Mike Rollings uses examples from Gartner's software development field research project to illustrate how to avoid this trap and how to instead develop cross-competency IT effectiveness.
2 June 2011
There is no doubt that as companies expand virtualization usage and build more business capability using cloud options (private and public), the role and skill set of the IT practitioner will need to change. What can IT professionals expect, what kind of options are ahead of them, and what do these changes of roles and skills mean to their careers and their organizations?
