The key enabling technologies in Cloud Computing are given below:
Distributed Computing -Cluster, Grid Computing.
Internet Technologies -Service Oriented Architecture, Web 3.0, etc.
Hardware Technologies – Virtualizations, Multi-core chips, etc.
System Management – Automatics Computing
Distributed Computing
Distributed computing visualizes the idea of connecting multiple computers through computer networks by using a distributed system. These computers can be different and the same and are located globally also. Distribute Computing consists of various parts: grid, clusters, web 2.0, and clouds. Clusters can be defined as multiple servers grouped to provide computing services to users.
Service-Oriented Architecture
Service-Oriented Architecture can be defined as the core development of cloud computing systems. It adopts the primary building block of application and system development. It is an architectural approach in which applications use services available in the network.SOA allows users to combine many facilities from existing services to form applications.SOA provides various functionalities for systematic design and integrates components into a smooth centralized system.
Web Services
A web service is application software available over the internet and uses a standard messaging system.XML is used to encode all communications to a web service. Software applications developed in various programming languages and running over various platforms use web services for intercommunication data exchange over networks.
