Gartner reveals enterprise cloud adoption plans through 2017

Global buyers of cloud applications cite cost, innovation and agility as reasons for adoption, according to a recent survey by Gartner. In May and June 2014, Gartner conducted a survey across 10 countries in four regions to examine organisations’ adoption and deployment of cloud services across SaaS, infrastructure as a service (IaaS) and platform as a service (PaaS). The countries included within the 2014 survey were the U.S., Brazil, Mexico, the U.K., Germany, France, China, India, South Korea and Australia.

“The most commonly cited reasons the survey found for deploying SaaS were for development and testing production/mission-critical workloads,” said Joanne Correia, research vice president at Gartner.

“We’ve seen a real transition from use cases in previous surveys where early SaaS adoption focused on smaller pilot projects. Today, the projects are mission-critical and production grade. This is an affirmation that more businesses are comfortable with cloud deployments beyond the front office running sales force automation (SFA) and email.”

Nearly 44 percent of survey respondents said that overall cost reduction continues to dominate as the main reason for investment. However, when the data is organised by role, the cloud adoption survey indicates that “cost reduction” rated highest for the more junior IT roles (IT staff and IT managers). Senior business executives (excluding CIOs) also rated “cost reduction” as a key benefit, but not at the same rate as the IT staff.

The CIO and IT director roles all rated “cloud is a modern approach,” “innovation” and “operational agility” as top drivers. The senior IT leaders also rated “business advantage” significantly higher than junior IT roles.

The conclusion is that CIOs are focused on using the cloud to establish a modern, innovative IT environment with operational agility and business advantage as key outcomes whereas business leaders (non-IT) still see the cloud as a means to save costs and may not yet have full appreciation for the business benefits or strategic opportunity of using cloud services.

Regardless of the reason of implementing cloud, Gartner advises that public cloud is not always the most appropriate model for all use cases within companies. The decision to deploy SaaS-based applications within an enterprise depends on the business-criticality of the solution, as well as the organisation’s geography, business agility, usage scenario and IT architecture. Therefore, few organisations will completely migrate to SaaS and will live with a mix of SaaS and traditional on-premises application deployment models, with a focus on integration and migration between different deployment models.

The survey found that security, privacy and fear of government snooping remain leading concerns for respondents (especially outside of the U.S.) that do not consider public cloud-based models. Although protection methods are continually upgraded and providers’ position public cloud services as secure, concerns remain.

“Data loss, data breaches, unsecure application programming interfaces (APIs) and shared technology in a multitenant environment are just a few of the concerns expressed by respondents tackling the option of using public cloud,” said Laurie Wurster, research director at Gartner. “In addition, recent concerns of government snooping in the name of anti-terrorism and general privacy issues contribute to the lack of public cloud adoption.”

In reaction to these concerns, respondents will push the adoption growth of private (a combination of internal or as hosted private cloud managed by a third party) cloud (46 percent) for deployment across all software markets by nearly twice the rate of public cloud (24 percent) adoption over the next two years.

The trend indicated by respondents’ cloud adoption behaviour for software deployment suggests the majority of data centres are moving to private cloud deployment for implementation of new software. The traditional deployment model for on-premises software is expected to significantly shrink from 34 percent to 18 percent by 2017. Legacy software will remain on-premises in the traditional model until end of life unless updates and upgrades allow for private cloud deployment models.

Despite security and privacy concerns, survey respondents continue to invest in public cloud for SaaS deployment of software applications.

Key drivers for SaaS include the fact that “hands off” IT enables redirection of limited in-house staff to other responsibilities since the SaaS provider is responsible for ongoing support. Rapid deployment and faster access to innovation are also important since SaaS vendors are able to roll out applications when you are ready and lower upfront costs with a pay-as-you-go pricing model.

“Although fewer respondents indicated investment in public cloud for platform as a service, business process as a service (BPaaS) and infrastructure as a service, the results are still significant in response to these emerging technologies. Cloud-hosted applications continue to grow as alternatives to internally managed systems; they will generate increasing demand for SaaS extension and integration - both functions of PaaS offerings,” said Fabrizio Biscotti, research director at Gartner.

“Although SaaS and IaaS are fairly consolidated, PaaS is still open for expansion, with both SaaS and IaaS providers looking at PaaS as a natural extension for growth. Of all the cloud technological aspects for which respondents indicated investments, BPaaS, IaaS and SaaS are the most mature and established from a cloud landscape perspective, while PaaS is the least evolved.”
