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 2013.

2014 Planning Guide for Cloud Computing

3 October 2013

Cloud computing is no longer a new concept, and many organizations have been consuming cloud services for the past several years. However, in 2014, many organizations will look to move cloud computing past the early phase and constrained use cases and into more widespread, production adoption.

Solution Path for Public Cloud Adoption Maturity Plan

8 November 2012

IT organizations must commit to a maturity transformation of their organizations, governance, technology, applications and management processes in order to better adopt public cloud services. This Solution Path presents a multiyear maturity plan for public cloud computing adoption.

Defining Cloud Computing

9 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

6 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.

Cloud Characteristics, Principles and Design Patterns

15 July 2012

How do you maximize the cloudiness of an IT solution? IT architects need a framework for evaluating cloud platforms and custom-developed applications intended to run on them. The benefits of cloud computing are realized by implementing an architecture with desirable characteristics, such as elastic scalability, metered consumption and self-service. This template defines the architectural principles and design patterns that maximize cloud characteristics and determines the cloud tier in which each pattern can be implemented (infrastructure, platform or application code). This template also guides architects around the anti-patterns that counteract potential benefits of cloud computing.

Building a Solid Cloud Adoption Strategy: Success by Design

19 May 2010

As cloud computing enters the adoption era, IT organizations are being asked to take a serious look at using cloud computing to lower costs and create a more agile IT environment. But cloud computing still presents many risks regarding data compliance, security, vendor viability, and liability. To date, cloud computing has been adopted in an ad hoc manner, often starting as "pilot projects" projects deep within the IT organization. For cloud computing to be successful, IT organizations need a solid, well thought-out cloud adoption strategy--one that takes into account the risks and rewards.

Hybrid Cloud Network Architecture

13 November 2013

A variety of hybrid cloud network architectures has emerged, and choosing the right one depends on both the use case and the cloud environment. Logically extending the corporate data center perimeter to the cloud should also be addressed and can be facilitated by SDN and network virtualization.

Solution Path for Public Cloud Adoption Maturity Plan

Decision Point for Selecting an Application's Cloud Migration Strategy

3 July 2012

The CIO issues a simple directive: "Move some applications to the cloud." To do this, architects face bewildering choices. 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.

Data Center Sourcing: Cloud, Host, Co-Lo, or Do It Yourself

2 September 2010

The decision to outsource or in-source applications that support a given enterprise function is not a simple matter. Just when IT organizations felt they had figured out what to outsource and what to keep in-house, cloud computing has fueled renewed interest in outsourcing and caused enterprises to reassess their IT services sourcing strategies. In this Decision Point, Managing Vice President Richard Jones describes the decision process to determine when and how enterprise applications should be sourced. Sourcing may be done internally or by one of many externally hosted cloud and managed- services models.

Self-Service Provisioning for Internal Clouds: Buy or Build?

6 September 2011

A fundamental requirement of internal clouds is the provision of on-demand self-service. Provisioning portals and IT service catalogs help reduce operating expense, thus providing benefits for both IT and organization users. IT can reduce architecture approval cycles and provisioning time, while users benefit from increased productivity and easier access to IT services. However, in a market with many immature products, IT must decide whether to buy a commercial solution or build a homegrown self-service platform. In this assessment, Research Director Alessandro Perilli reviews alternatives and provides guidance on how to engineer the internal cloud provisioning stack.
