While cloud computing cops a bashing from some industry pundits, it
could in fact be one of the more important factors in helping
enterprises cope with the economic downturn. This is the belief of a
leading industry analyst.
According to Steve Hodgkinson, research director
at Ovum, as the effects of the meltdown in the global financial sector
spread
throughout the economy the cloud will become an ever more important
strategy for reducing both capex and opex – giving CIOs new options for
responding to budget pressures in recessionary times.
"While it is wise to be sceptical of marketing hype, we should not
forget that there is real substance in the cloud," says Mr Hodgkinson
in a research note.
Mr Hodgkinson identifies the real champions of cloud computing as not
SaaS leader Salesforce but rather Internet giants like Google and
Amazon.
"While Salesforce.com is credited with popularising
software-as-a-service the broader notion of cloud computing has been
launched by the likes of Amazon and Google," says Mr Hodgkinson.
"These internet giants
introduced platform-as a-service offerings to boost the ROI of their
massive global computing infrastructures. For start-ups and SMBs there
is great appeal in the “IT-department-as-a-service” provided, for
example, by Amazon Web Services, Elastic Compute Cloud (EC2) and Simple
Storage Service (S3) and by Google Mail, Docs and App Engine."
Mr Hodgkinson also indicates in his note that cloud computing is a much broader term than SaaS.
"While the ‘as-a-service’ label has increasingly been applied to three
bundles (software, data and platform) cloud computing has become very
broad - encompassing applications ranging from ERP systems through to
widgets; application development tools and environments; storage;
processing; systems management and security. Cloud computing =
‘as-much-ICT-as-you-want-as-a-service’."
He also identifies the charactistics that make cloud computing an attractive proposition for ICT users:
· Provided as a standardised utility: a set of service
offerings provided largely on a similar, un-customised, basis to all
customers - enabling unparalleled economies of scale.
· Delivered via the internet (of course): using industry
standard IP protocols and benefiting from the massive scale of
investments in global internet capacity.
· Accessed via a web browser: providing a generic interface independent of operating system or access device.
· Founded on open standards and APIs: using SOA principles and web services logic.
· Self served: enabling customers to enrol in the service and manage their usage via online self-serve processes.
· Inclusive of a range of services: from front-end applications through to back-end raw compute capacity.
· Always on: 24x7 global availability.
· Scalable: able to absorb major variability in processing and storage demands.
· Pay as you go: with usage driven charges and minimal up-front contractual commitments.
· Public or private: able to be deployed on an open global ICT
infrastructure or a partitioned infrastructure specific to a customer’s
needs.
Despite its obvious benefits, Mr Hodgkinson believes cloud computing is
not a universal panacea, especially for mission critical applications.
"Enterprises, however, are quite right to be cautious about relying on
such consumer/SMB oriented suppliers for anything resembling a mission
critical application or service," he says.
Despite its present shortcomings, though, Mr Hodgkinson does believe
there is a bright future for cloud computing in the enterprise.
"Most recently the major IT companies have started to see gold in the
cloud, and are investing in both purpose-built cloud computing
infrastructure and in developing solutions to enterprise concerns
regarding cloud trustworthiness.
"IBM is expanding its network of ‘Blue Cloud’ computing data centres
and is making substantial investments in cloud computing R&D. HP,
Intel and Yahoo are partnering to create new cloud R&D centres.
Oracle and Intel are partnering on cloud infrastructure development."
