Cluster Computing Parallel and distributed system Connects Multiple stand-alone computers into a

Single integrated computing resource Connects through Fast LAN Used for Load Balancing and High Availability

Distributed Computing A problem is divided into many tasks, each of

which is solved by one computer. The system has to tolerate failures in individual

computers.

Grid Computing parallel distributed computing Combination of computer resources from multiple

administrative domains

Enables sharing, selection, and aggregation of geographically distributed computers

Connected by a conventional network interface, such as Ethernet

Cloud Computing Software as a Service

software for customer use

Rather than purchase the hardware and software to run an application, customers need only a computer or a server to download the application and internet access to run the software.

Cloud Computing Platform as a Service

user-built applications onto the cloud infrastructure built using programming languages and software

tools supported by the provider (e.g., Java, python, .Net)

Cloud Computing Infrastructure as a Service

Allows users to rent processing, storage, networks, and other resources.

User can deploy and run the guest OS and applications

User has control over OS, storage, deployed applications, and possibly select networking components

Cloud types

21from wiki

Cloud Computing Public Cloud

Used by general public cloud consumers Owned by service provider Earn profit base from users’ requirement

22

Cloud Computing Private Cloud

Operated and managed by single organization or third party

Maximize and optimize the utilization of existing in-house resources

Security concerns Organizations always require full control For academic research and teaching purposes

23

Cloud Computing Hybrid Cloud

Combination of 2 or more clouds To optimized their resources Help raised the issues of standardization and

cloud interoperability
