Open Source IaaS Software offering a real alternative to
Infrastructure as a Service (IaaS) is a service model where an
organization outsources the equipment used to support storage,
hardware, servers and networking components. In other words, IaaS
offers access to computer resource in a virtualised environment, known
as the Cloud, across a public connection. With IaaS individuals can
rent cloud infrastructure, server storage and networking on demand.
IaaS is one of the three fundamental service models of cloud
computing. The other service models are Platform as a Service (PaaS)
and Software as a Service (SaaS). We examined the finest open source
PaaS software in the following article: PaaS
A typical IaaS offers scalability which is particulary useful
for workloads that are highly volatile. IaaS also offers utility style
costing, location independence, no single point of failure, and
physical security of data centre locations. The advantages are so
great, IaaS is the fastest growing area of cloud computing.
With commercial cloud systems, there is no investment in
hardware required. This enables start-up businesses to easily test out
a new business idea. Whilst commercial cloud services are popular, they
charge for CPU usage by the hour, storage, and bandwidth consumed. In a
large organization, where many users need to be served, it may be
cheaper to purchase hardware to create a private cloud. This article
showcases the finest open source projects that provide a key
alternative for those who wish to avoid using a commercially
Now, let's explore the 8 open source IaaS software at hand.
