PuAmazon. AWS (http://aws.amazon
.com) continues being the dominant
player in cloud computing, thanks to
Amazon having been the rst company
to offer cloud services, in 2006.
AWS is cost effective. Its pay-asyou-
go model lets you scale cloud
capacity up or down without paying
a high price. It also offers many additional
IaaS services and integrated
monitoring tools. It’s particularly
valuable for startups and agile projects
requiring quick, cheap processing
and storage.
Because AWS is a general provider,
you can operate independently,
which is convenient for normal operations
but becomes risky when problems
occur. Extensive technical support
is a premium feature, whereas
most of AWS’s competitors offer it as
a standard feature.
Microsoft Azure. Azure (http://
azure.microsoft.com/en-us) entered
the cloud IaaS market in February
2010. It has a large market share
and is a good candidate because of
its market position in other areas.
It offers compute and storage services
similar to those of other IaaS
providers, and it allows full control
and management of virtual machines.
Additionally, Azure’s UI is
easy to use, especially for Windows
administrators. However, because
the Azure offering is newer than
Amazon’s or Rackspace’s, it still has
many features in “preview” mode
and still has networking and security
gaps.
