Utilization and efficiency improvements for systems that are often only
Performance is monitored and consistent but can be affected by insufficient
bandwidth or high network load.
Reliability by way of multiple redundant sites, which makes it suitable
for business continuity and disaster recovery, however IT and business
managers are able to do little when an outage hits them. Historical data on
cloud outages is tracked in the Cloud Computing Incidents Database.
Scalability which meets changing user demands quickly, without having to
engineer for peak loads. Massive scalability and large user bases are common
but not an absolute requirement.
Security which typically improves due to centralization of data, increased
security-focused resources, etc. but which raises concerns about loss of
control over certain sensitive data. Accesses are typically logged but accessing
the audit logs themselves can be difficult or impossible.
Sustainability through improved resource utilisation, more efficient systems
and carbon neutrality.
Driving Factors Behind Cloud
If you're an IT manager or senior IT executive in the evaluation phase for turning over some of your
infrastructure to the cloud, you’re not alone. Cloud adoption can vary by industry and organization,
but cloud computing is rapidly making inroads into most organizations. According to a recent survey
of 600 senior IT and business executives by Savvis, 70 percent of IT decision makers are using or
plan to use cloud computing in their own enterprises within 24 months.
While concerns about security, identity, SLAs, and other topics are still on the minds of many IT
pros, those concerns are gradually being addressed by cloud providers. While cloud computing may
not be a complete solution for every enterprise—nobody is talking about ditching internal data
centers yet, and probably never will—a number of pressing factors are driving the growth of cloud
computing. I’ll cover some of the biggest drivers towards cloud computing adoption here.
Improved IT Agility
As recently as a few years ago, it took far too long for many IT departments to respond to increasing
demand for computing capacity. Too much paperwork, too many approvals, and a reliance on hardto-deploy physical servers meant that IT was often slow to respond to variable organizational needs.
Virtualization helped that situation immensely, and the arrival of cloud computing gives IT
