BACKGROUND

WHAT IS CLOUD MANUFACTURING ?

• Computing may someday be organized as a public utility just as the telephone system is a public utility. The computer utility could become the basis, of a new and important industry. (John McCarthy, 1961)
• Cloud computing is a large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet. (lan Foster, 2008)

WHAT IS CLOUD COMPUTING ?

• In addition, the platform provides on demand services, that are
• always on, anywhere, anytime and any place.
• Pay for use and as needed, elastic
• scale up and down in capacity and functionalities.
• The hardware and software services are available to
• general public, enterprises, corporations and businesses markets.

CLOUD SUMMARY

• Cloud computing is an umbrella term used to refer to Internet based development and services.
• A number of characteristics define cloud data, application services and infrastructure:
• Remotely hosted: Services or data are hosted on remote infrastructure.
• Ubiquitous: Services or data are available from anywhere.
• Commodified: The result is a utility computing model similar to traditional that of traditional utilities, like gas and electricity - you pay for what you would want!

CLOUD FUNDAMENTALS

CLOUD COMPUTING SERVICE LAYERS

• Application focused : -
• Services - Complete business services such as PayPal, OpenID, OAuth, Google Maps, Alexa
• Application - Cloud based software that eliminates the need for local installation such as Google Apps, Microsoft Online
• Development - Software development platforms used to build custom cloud based applications (PAAS & SAAS) such as SalesForce
• Infrastructure focused : -
• Platform - Cloud based platforms, typically provided using virtualization, such as Amazon ECC, Sun Grid
• Storage - Data storage or cloud based NAS such as CTERA, iDisk, CloudNAS
• Hosting - Physical data centers such as those run by IBM, HP, NaviSite, etc

Resource Management - Taxonomy of Metrics

RESOURCE MANAGEMENT

Design goals : -

• Decentralized decision making
• Fault tolerance
• Scalability
• SLA violations
• Energy efficient
• Reduced complexity
• Security and trustworthiness
• Load balancing

OPPORTUNITIES AND CHALLENGES:

• The use of the cloud provides a number of opportunities:
• It enables services to be used without any understanding of their infrastructure.
• Cloud computing works using economies of scale:
• It potentially lowers the outlay expense for start up companies, as they would no longer need to buy their own software or servers.
• Cost would be by on-demand pricing.
• Vendors and Service providers claim costs by establishing an ongoing revenue stream.
• Data and services are stored remotely but accessible from "anywhere".

• In parallel there has been backlash against cloud computing:
• Use of cloud computing means dependence on others and that could possibly limit flexibility and innovation:
• The others are likely become the bigger Internet companies like Google and IBM, who may monopolise the market.
• Some argue that this use of supercomputers is a return to the time of mainframe computing that the PC was a reaction against.
• Security could prove to be a big issue:
• It is still unclear how safe out-sourced data is and when using these services ownership of data is not always clear.
• There are also issues relating to policy and access:
• If your data is stored abroad whose policy do you adhere to?
• What happens if the remote server goes down?
• How will you then access files?
• There have been cases of users being locked out of accounts and losing access to data.

ADVANTAGES OF CLOUD COMPUTING 

• Lower computer costs
• Improved performance
• Reduced software costs
• Instant software updates
• Improved document format compatibility
• Unlimited storage capacity
• Increased data reliability
• Universal document access
• Latest version availability
• Easier group collaboration
• Device independence

DISADVANTAGES OF CLOUD COMPUTING 

• Requires a constant internet connection
• Features might be limited
• Stored data might not be secure
• Stored data can be lost
• HPC Systems - Not clear that you can run compute-intensive HPC applications that use MPI / OpenMP!

THE FUTURE 

• Many of the activities loosely grouped together under cloud computing have already been happening and centralised computing activity is not a new phenomena.
• Grid Computing was the last research-led centralised approach.
• However there are concerns that the mainstream adoption of cloud computing could cause many problems for users.
• Many new open source systems appearing that you can install and run on your local cluster
• should be able to run a variety of applications on these systems.
