Cloud Computing Technologies

• Virtualization
• Service-Oriented Architecture (SOA)
• Grid Computing
• Utility Computing

• It is the process of creating a virtual environment.
• To run multiple applications and operating systems on an equivalent server.
• It is combination of many operating systems, storage devices, network application servers, and other environments.
• It is increases the use of virtual machines.

• Hardware virtualization
• Server virtualization
• Storage virtualization
• Operating system virtualization
• Data Virtualization

• It allows organizations to access on-demand cloud-based computing solutions according to the change of business needs.
• It can work without or with cloud computing
• The main advantages of using SOA are that it is platform independent, easy to maintain, and highly scalable.

There are two major roles:

• Service Provider
• Service consumer

• Healthcare industry.
• Create many mobile applications and games.
• In the air force , It is used to deploy situational awareness systems.

• Grid computing is also known as distributed computing. It is connected by parallel nodes to form a computer cluster. In these clusters are in different sizes.
• It can run on any operating system.

Three types of machines

• Control Node - It is a group of server which administrates the whole network.
• Provider - It is a computer which contributes its resources in the network resource pool.
• User - It is a computer which uses the resources on the network.

• Utility computing is the most trending IT service model. It provides on-demand computing resources (computation, storage, and programming services via API)
• It is based on the pay per use method.
• It low costs and maximizes the efficient use of resources.
• It is easy to manage.
