The rise of hybrid clouds
It seems that many analysts, e.g. at the Cloud Computing Journal,
are proclaiming that private and hybrid clouds will see a real
proliferation in 2010. Security concerns of public clouds are still
prevailing and many IT professionals and managers are still very
reluctant to the idea of migrating private enterprise data and
operations to a public cloud provider. Deploying cloud computing
on-premise, in a private cloud fashion, is seen as a way to exploit many
of the benefits from cloud computing, i.e. automation, centralization
and elasticity, without the security risks still lurking around in
public clouds. In private clouds, organizations maintain closer security
and compliance controls over their applications and data. In the longer
term though, together with increased cloud adoption, managers will
probably compare more seriously the cost/benefit analysis of private
versus public clouds.
Alternatively, hybrid clouds, seem as a sensible
intermediary step between public and private clouds, enabling
organizations to leverage upon both worlds – combining on-demand
capacity with in-house compliance.
Implementing a hybrid cloud strategy is simply an attempt to
augment a private cloud with the resources of a public cloud in order to
maintain acceptable service levels despite spikes in demand, i.e. to
address and prevent the so called Cloudbursting (“the failure of a cloud computing environment due to the inability to handle spike in demand”).
Hybrid clouds seem a natural step for enterprises not interested or
willing to migrate resources to the public cloud due to
security vulnerabilities or otherwise. Getting their feet wet in the
cloud without risking too much, hybrids clouds may offer a beneficial
alternative for dealing with temporary spikes in demand, lowering
capital costs and offer the elasticity desired.
