Cloud computing aims at providing dynamic leasing of server capabilities as scalable, virtualized services to end users.
Server virtualization aims to reduce the cost of service provisioning and improve fault tolerance, portability and security of virtualized services by sharing the resources amongst consolidated servers.
Provoked by the need to enable agile deployment of new services while, at the same time, slashing operating expenditure and energy consumption, the trend in telecommunications is to shift functionality from physical appliances to virtualized services.
The analysis is based on a typical architecture starting from a single sensor and actuator and continuing to the virtualized services at smart dust, dew, fog and cloud level.
The technology industry's current stance on cloud computing appears to now be steadfastly focused some distance beyond the core creation of new datacenters and the overall proliferation of virtualized service-based computing.
Anypoint: Redirection architecture to support a general class of virtualized services using IP-based transports.
Any new application we put out there is going to be running on a set of virtualized services.
NFV has recently emerged as a new paradigm for providing network and telecommunication services, i.e., network functions offered by virtualized services for servers with a general purpose.
However, cloud and virtualized services make this a dated process, given that we need to now differentiate between certain items like an outage in a server, a network card, a piece of the storage infrastructure, or a security exploit.
