Cloud computing, virtualization both have faults, promises

For several years, enterprises have been migrating data, applications and servers to virtual environments that are not connected to hardware. In the past, decision-makers leveraged virtualization technologies to achieve these goals but have since shifted their focus to the public and private cloud, according to a CIO U.K. report.

While virtualization and private cloud strategies are often confused, there are differentiations between the two technologies. Virtualization is an IT fixture, while the cloud offers on-demand resources through a pay-as-you-go pricing model.

In addition to differences in their definition, there are also technological distinctions that could convince IT executives to lean one way or another.

Financial and flexibility variations between cloud computing and virtualization

Cost, for example, is one of the biggest differentiators. Virtualization services can help companies achieve greater flexibility but often comes at a more expensive price, as setting up and customizing the environments take significant time and effort. Cloud computing structures, on the other hand, are usually already set up by the provider which enables vendors to pass the savings on to the end-user.

The cloud also leverages a low pricing model that allows companies to only pay for what they use. As a result, organizations that utilize minimum processes have the potential to experience big savings, while still having the ability to use next-generation applications and solutions.

Security concerns and benefits associated with different technologies

In addition to cost, virtualized environments also give decision-makers much more control over public cloud environments, which are hosted and managed off-site. This is important for organizations that want a higher degree of control, enabling IT executives to make changes to infrastructure to enhance flexibility, CIO U.K. noted. Greater control also allows IT departments to implement more robust data security tools, keeping mission-critical and sensitive solutions more secure.

Reliability is also a concern for both virtualization and cloud computing. The cloud, however, is often viewed as being more resilient, as service providers likely have more tools in place to resolve issues that may crop up unexpectedly, the news source said.

Meanwhile, the cloud is often more scalable than virtualization technologies, allowing organizations to continue working through times of high traffic without worrying about experiencing downtime or bottlenecks that could inadvertently expose sensitive solutions.
