Check out these fun, introductory videos which illustrate the evolution of virtualisation software and its use in the cloud computing business and operating model.
Virtualisation is the software underlying on-demand cloud services, allowing enterprises to consolidate several servers into one.
By the year 2020, 80% of all computing is expected to take place within the cloud. Currently service providers are aggressively positioning new private and public cloud offering to enterprise customers within the Iaas, PaaS and SaaS layers.
Generally, clients have the option to move forward with entry-level VPS services or consume more powerful IaaS platforms which offer network admins root access to the underlying server.
The utility pricing model of a cloud allows an IT manager to incrementally migrate on-premise datacentre servers (and apps) to remote web hosting companies at lower price points.
The ability to scale up and down on services simplifies datacentre operations and contributes to agile software development.
