CLOUD COMPUTING

INTRODUCTION
Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network.
Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallel to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.

Cloud computing providers deliver applications via the internet, which are accessed from web browsers and desktop and mobile apps, while the business software and data are stored on servers at a remote location. In some cases, legacy applications (line of business applications that until now have been prevalent in thin client Windows computing) are delivered via a screen-sharing technology, while the computing resources are consolidated at a remote data center location; in other cases, entire business applications have been coded using web-based technologies such as AJAX.
Types of Cloud Computing
1. Web-scale problems
2. Large data centers
3. Different models of computing
4. Highly-interactive Web applications
1. Web-Scale Problems:
• Characteristics:
a. Definitely data-intensive
b. May also be processing intensive
• Examples:
c. Crawling, indexing, searching, mining the Web
d. “Post-genomics” life sciences research
e. Other scientific data (physics, astronomers, etc.)
f. Sensor networks
g. Web 2.0 applications…
2. Large Data Centers:
• Web-scale problems? Throw more machines at it!
• Clear trend: centralization of computing resources in large data centers
3. Different Computing Models
• Utility computing
• Platform as a Service (PaaS)
• Software as a Service (SaaS)
4. Web Applications:
• A mistake on top of a hack built on sand held together by duct tape?
• What is the nature of software applications?
• How do we deliver highly-interactive Web-based applications?
Accessing resources by cloud computing:
Cloud computing provides computation, software, data access, and storage services that do not require end-user knowledge of the physical location and configuration of the system that delivers the services. Parallel to this concept can be drawn with the electricity grid, wherein end-users consume power without needing to understand the component devices or infrastructure required to provide the service.
Cloud storage:
Cloud storage is a model of networked online storage where data is stored on virtualized pools of storage which are generally hosted by third parties. Hosting companies operate large data centers; and people who require their data to be hosted buy or lease storage capacity from them and use it for their storage needs. The data center operators, in the background, virtualizes the resources according to the requirements of the customer and expose them as storage pools, which the customers can themselves use to store files or data objects. Physically, the resource may span across multiple servers.
Different workers:
• Different threads in the same core
• Different cores in the same CPU
• Different CPUs in a multi-processor system
• Different machines in a distributed system
