Cloud-based email applications such as Gmail and Microsoft Exchange Online will help boost Webmail to more than half the total email enterprise seats within the decade, said Gartner.
Web-based email will comprise at least 10 percent of the
license seats in enterprises through 2014 but will hit 55 percent by 2020 as
it reaches mass adoption, according to Gartner.
Web-based, or cloud email, is hosted by providers such
as Google (NASDAQ:GOOG), Microsoft (NASDAQ:MSFT), VMware's Zimbra unit and
several startups, and provisioned to users over the Web. Many people question
the security of this approach.
However, the cloud saves IT administrators the time and
hassle of setting up and configuring on-premises email systems such as
Microsoft Exchange Server and the Outlook user software, as well as IBM
Lotus Domino Server and Notes user client.
Gartner, which has keenly tracked the rise of Google's Gmail,
Microsoft Exchange Online and other rivals, recommends smaller businesses, or
even sectors such as retail, hospitality and manufacturing to move to
cloud-based email over the next two years.
Gartner analyst Tom Austin
said the cloud will come to represent the dominant provisioning model business communication and
collaboration technologies in 10 years.
Why will it take that long, when Gmail
has 40 million users in Google Apps, and Microsoft Exchange Online will no
doubt leverage the company's massive enterprise reach to gain traction?
Austin blamed "asset inertia," in which
businesses are loath to switch from their long-term on-premises email contracts;
the focus on strategic, rather than cost-cutting plays to gain competitive advantages,
and Webmail systems whose promise is greater than their practice.
Moreover, most businesses that say they use cloud email
also retain small on-premises systems to house and protect sensitive data
generated by C-level executives.
Austin said businesses hold back from going all in with
the cloud because of the perception that early adopters pay a premium in terms
of acquisition cost.
Noting that cloud-based systems are forward-priced, Austin
said businesses should secure cloud contracts now, but force vendors to commit
to reducing prices as the cloud email becomes a commodity instead of a
Google charges $50 a user per year for its Google Apps,
which includes Gmail, Google Docs and several other apps. Microsoft Exchange
Online is part of Office 365
, which includes tiered pricing starting at $6 per user, per month.
Austin's colleague Matt Cain proclaimed Gmail a credible enterprise email
alternative to Microsoft Exchange
. Austin and Cain will present their findings at the
Gartner Symposium/ITXpo in Orlando, Fla., next month.
