With tightened budgets, businesses are constantly looking for way to see a rapid return on investment (ROI). This has increased interest in the adoption of pay-as-you-go cloud services and virtualisation technologies where the ROI can be very attractive.
In recent months, Tom Brand, virtualisation practice lead at GlassHouse Technologies (UK) has found himself frequently answering the question: “What is the difference between cloud computing and virtualisation?” In Tom’s latest blog post he gives his view…
In order to answer this question it is first important to clarify what the two terms, cloud computing and virtualisation, actually mean:
According to the National Institute of Standards and Technology (NIST), cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
Virtualisation is a technique used to abstract the physical characteristics of computing resources from the systems, applications or end users that interact with those resources.
