Hybrid IT is the result of combining internal and external services, usually from a combination of internal and public clouds, in support of a business outcome. Adoption risks of public clouds have led to architectures that connect internal core services and critical data to external, commoditized services.

Hybrid IT relies on new technologies to connect clouds, sophisticated approaches to data classification and identity, and service oriented architecture. In addition, the role of IT and its practitioners is undergoing significant change.

Gartner Technical Professional Research Analysts discuss business and technology trends for 2014.

Defining Cloud Computing

09 January 2012

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.

Cloud Computing Tiered Architecture

06 January 2012

Clients continue to request help with understanding cloud computing architecture and information. Unfortunately, the volume of hype and conflicting information slows down the adoption of cloud computing, but IT organizations are aware that implementing cloud services is complex. If cloud computing is to mature, IT organizations must develop a cloud adoption strategy -- a strategy that is built on a simple, easy-to-understand architecture. This Gartner cloud computing root template depicts the root diagram for cloud computing by breaking it into three separate tiers. Using this template, IT organizations can level-set cloud comprehension, understand its value, and devise an adoption strategy.

In this Decision Point, Richard Watson steers architects to a choice from among five alternatives: rehost on IaaS, refactor using IaaS and PaaS, revise for IaaS or PaaS, rebuild on PaaS, or replace with SaaS. The decision must consider an organization's requirements, evaluation criteria, and architecture principles. However, no alternative offers a silver bullet: All alternatives require architects to understand application migration from multiple perspectives and criteria, such as IT staff skills, existing investments, and application architecture.
