Despite software as a service's potential to be the next wave of IT, it's still a client-server world. Meanwhile, vendors are busy colonizing the cloud with new "as a service" options, such as cloud-based VDI, data analytics and e-Discovery services.
Cloud computing's software-as-a-service model may
one day dominate the world of IT, but across the vast expanse of the world's IT
departments, that morning hasn't yet seen its dawn.
For all its efficiency, cost savings and
centralized control, SAAS hasn't yet convinced most of the world's IT decision makers
that it is worth a leap of faith.
"There's no question that SAAS, even though the
technology is ready for the enterprise, isn't being adopted at the rate that
some people thought it would be by this time," data center analyst Greg Schulz
(pictured) of StorageIO and author of "The Green and Virtual Data Center" told eWEEK.
"Companies are going to go with what works. If a
client-server system installed seven years ago still works and gets the job
done, they will stay with it but keep a close eye on it at the same time. If
the budget opens up, a refresh is needed and the tech is there, then they may
make a change. But the conditions all have to be right," he said.
IT leaders express continuing reservations about data
security, 24/7 access to data in a public cloud, and whether a provider will
still be here years from now. If it's outside the firewall, it's not completely
controllable, and IT managers tend to like complete control.
But over the long haul, this hesitation due to
skepticism should work out to be a good thing. It is giving software developers
and SAAS providers more time to innovate, work out bugs and prepare a better
overall product. For instance, in 2009, companies considering Amazon's IAAS
(infrastructure as a service) EC2 (Elastic Compute Cloud) had to worry about
the service's lack of PCI compliance. In 2010, a newly PCI-compliant EC2 meant
that Amazon's service switched from being a PCI liability to being a potential
Along similar lines, new SAAS-based product
offerings are now moving out to what was just a short time ago uncharted
waters, for example, cloud-hosted "big-data" analytics, e-discovery, and in one of the areas of computing most
closely associated with on-premises solutions, the hosting of individual
Is SAAS VDI (virtual desktop infrastructure) the
missing link in getting virtual desktops off the corporate wish list and into
regular use? The enterprise client-server system may have run its course with
Win 7, and VDI has been a tantalizing alternative for about 12 years. Large new
deployments by Lawrence Livermore Laboratory, GE and Wells Fargo indicate that
big enterprises are now buying into this. What does the future hold?
