Cloud Computing vs. Virtualization: There is a Difference

Cloud Computing vs. Virtualization: There is a Difference

Virtualization as a Subset of the Cloud

Cloud Computing and Virtualization are not synonymous. You can think of Virtualization as a subset of the Cloud. Cloud Computing is inclusive of Virtualization and a way to implement it. However, Cloud can be implemented without Virtualization.

Cloud Computing

Cloud Computing has become a popular catch phrase in the technology industry – but what does it mean? The easiest way to understand is to break the phrase apart.

The “Cloud” is best understood as a special type of locker that is always accessible through network connectivity. Clouds provide anything from file storage to real-time application access. Just like the clouds we see every day, an IT “Cloud” can exist anywhere and in multiple places. Given the right solution, a “Cloud” could exist in your own datacenter or co-location facility.

Computing is a very common phrase that often means utilizing a computer or computer-based service. When we put the two phrases together, “Cloud Computing” becomes the use of a computer service that resides elsewhere.

Anything from simple file storage to a remote facility that houses all end-user desktops can be considered Cloud Computing. The task of developing the most effective Cloud Computing solution for your end-users can be daunting, but Lantana has the resources you need to help you evaluate and deploy the Cloud Computing solution that best fits your needs.

Virtualization

Too many servers in the data room? Need to reduce maintenance/operational cost of your servers? Still haven’t developed a high-availability solution for your most critical applications? — Time to virtualize!

Virtual Server solutions consist of two key factors:
  • Host: The physical server responsible for resource allocation and network access.
  • Guests: The virtual machine itself, running any Operating System and software application for end-user access.

Dedicated physical server deployments are considered inefficient in areas of rack-space, power consumption, and even resource allocation. Instead of having three separate physical servers run your domain, email and web services, you can (and should) consolidate them into a single Host machine, while maintaining all existing configuration and storage settings. As an added bonus, you could take one or more of those (now) extra servers and turn it into a secondary Host to solve that high-availability problem. Ask a Lantana resource how a virtualization solution best fits your needs!

Cloud Computing Versus Virtualization

Cloud or Virtualization:
What’s Right for Your Environment?

The Cloud
  • Increase scalability of existing applications
  • Expand and contract capacity on-demand
  • Support parallel workloads
  • Increase customer self-service
  • Support dynamic workloads
Virtualization
  • Consolidate hardware footprint
  • Increase service availability
  • Move legacy applications onto modern hardware

    One differentiator between Cloud and Virtual servers is that Cloud servers are remote, and Virtual Servers tend to be local. It is possible to have a local cloud, but unless you’re the CIA or a very large corporation, if you want to keep your servers local, you will be using virtualization. And, for the forseeable future, there will be valid security and bandwidth issues that will push some companies toward locally hosted servers.
