Cloud Architecture and cloud models in the internet

Cloud computing is the use of hardware and software to deliver a service over a network. It is on demand computing resources in which users can access files and use application from any device that can access the internet on a pay for use basis. Instead of computers hard drive we are using it.

In P2P network, every node (peer) acts as both a client and server.
No central coordination or central database is needed.
The system is self-organizing with distributed control.
Unlike the cluster or grid, a P2P network does not use dedicated interconnection network.
Infrastucture,Grids are heterogeneous clusters interconnected by high-speed networks
Infrastucture
It does easy task with large scale company.
They have centralized control and are server-oriented with authenticated security.
They are suited to distributed supercomputing. The grid is constructed across LANs, WANs or Internet backbones at a regional, national or global scale.
The computers used in a grid include servers, clusters, and super-computers.
PCs, laptops, and mobile devices can be used to access a grid system.

1. Cloud computing . Cloud computing is the use of hardware and software to deliver a service over a network. It is on demand computing resources in which users can access files and use application from any device that can access the internet on a pay for use basis. Instead of computers hard drive we are using it.

3. Cluster Computing : Consists of interconnected stand-alone computers which work cooperatively as a singleintegrated computing resourc e . Similar type of nodes are grouped together

4. Figure shows the architecture of a typical server cluster built around a low-latency, high bandwidth interconnection network The network of compute nodes are connected by LAN/ SAN,etc They are typically homogeneous with distributed control running Unix/Linux

5. Peer-to-Peer networks : The P2P architecture offers a distributed model of networked systems. Each system is connected by each other and each data is shared to each system In a P2P system, every node acts as both a client and a server, providing part of the system resources. Peer machines are simply client computers connected to the Internet. All client machines act autonomously to join or leave the system freely.

7. Grid computing Infrastructures Infrastucture , Grids are heterogeneous clusters interconnected by high-speed networks Infrastucture It does easy task with large scale company. They have centralized control and are server-oriented with authenticated security. They are suited to distributed supercomputing. The grid is constructed across LANs, WANs or Internet backbones at a regional, national or global scale. The computers used in a grid include servers, clusters, and super-computers. PCs, laptops, and mobile devices can be used to access a grid system.

8. Cloud Computing over an internet A Cloud is a pool of virtualized computer resources. Workloads can be deployed and scaled out quickly through rapid Virtual Machines. Virtualization of server resources has enabled cost effectiveness and allowed cloudsystems to low costs to benefit both users and providers. Cloud computing applies a virtualized platform with hardware, software, and data sets dynamically.
