Cloud Computing  It is for service Oriented.  The computing resources are managed centrally and are placed over multiple servers in clusters. Provides services such as hardware, software resources through the internet.  The cloud servers are owned by Infrastructure providers and are placed in physically disparate Locations. Platformas-service, software-as-a-service.  It can also be accessed through the internet.  It involves dealing with common problem using varying number of computing resources.  More than one computer coordinates to resolve the problem together.

Distributed Computing  A computing technique that allows multiple computers to communicate and coordinate work by passing messages through the network to achieve a common task.  Helps to achieve computational tasks faster than using a single computer.  Goals are resource sharing  Openness  transparency  Scalability  Technologies such as Remote procedure Calls and Remote method invocation are used to construct distributed computations.

Grid computing  It is for Application Oriented.  The resources are distributed among different computing units for processing a single task.  Grids are generally owned and managed by an organization within its premises.  It operates within a corporate network.  It provides a shared pool of computing resources on an as needed basis.  It is a collection of interconnected computers and networks that can be called for large-scale processing tasks.

Utility Computing  Utility computing is a business model that charges customers for computing, memory and bandwidth based on how much is used.  Virtualization improves resource Utilization and reduces CAPEX, OPEX.  Metered bandwidth  Self-service provisioning  Rapid scalability.
