Server Virtualization vs. Cloud Hosting

Many people are confused about the differences between server virtualization and cloud computing. We’re here to set the record straight! Let’s begin by properly defining them both.

Server virtualization is the use of specialized software to segment an individual server into multiple units known as containers. What’s important to remember here is that server virtualization refers specifically to the process of divvying up infrastructure in this manner. Server virtualization also occurs in a local environment. Cloud computing, however, also utilizes virtual servers, but refers to the actual process of doing so. It is the practice of using remote resources to complete a task or function without assigning the task to a local machine.

Advantages of One Over the Other?

While there are camps who would make the argument that one of these is better than the other, the greatest impact server virtualization and cloud computing can have is when they’re working together. The cloud can provide levels of scalability and flexibility that virtual servers can hardly match – especially a private cloud. On the other hand, cloud-based solutions cannot compete on price or the ability for the user to manage his or her own server.

To determine whether your organization should be utilizing server virtualization or cloud computing, you really have to evaluate your own needs. The traditional questions about transfer space, bandwidth, support and downtime are all very applicable, as usual, but when determining between virtual servers or cloud solutions, one must also research providers. For instance, there is a lot of misunderstanding in our industry about what hosting plans actually offer. Many providers are offering trendy “cloud computing” plans (and higher prices!) but actually still providing virtual servers. When considering any hosting provider, you want the peace of mind that comes with knowing that they are ready to support their product inside and out. If you can’t get clear information about exactly what they have to offer, chances are they won’t be able to meet your needs.
