Cloud Computing Definition
The narrow cloud computing is a IT infrastructure deliver and usage model, means deliver and use the resource(hardware,plateform,software) with on-demand and easy to scale through internet. The network to provide resource is called cloud, the cloud seems like scalable infinitely, can get it anytime, and use and scale it on demand, pay per use.
The generalized cloud computing is a service deliver and usage model, means deliver and use the service with on-demand and easy to scale through internet. These service can have relation with IT/software/Internet, or any another service.
Cloud computing is what, isn’t what
Cloud computing is an IT revolution, an IT revolution to improve the social productivity, an IT revolution to advance the infomationization of the whole society, is a collection of business models with the same core features.
Cloud computing is not one business model, is not a kind of payment method, is not an IT technology, is not an IT product, is not SOA, is not virtualization or virtualization management softewrae, is not simply the change of purchase to lease, is not distributed computing, is not high performance computing, is not grid computing, is not Saas.
Why does cloud computing come?
Why does this cloud computing revolution come? Like any other revolution, it is a result of the technology progress, market requirement drive, business model transition. The major driving factors include: The virtualization tech and market's fast develop The hardware's fast develop, like CPU and network device The wide band network's fast develop The fast increase of corporate IT infrastructure requirement The fast change and time-to-market requirement of Internet application The recognize of cloud computing business models Some cloud computing pioneers seems earning money Economy crisis force companies to cut cost
How cloud computing change IT industry?
Cloud computing will give many IT domains revolutionary impact: Chip design and manufacture Server and PC IT infrastructure out sourcing Internet application Desktop application IT department of SME IT department of big enterprise Platform as a service Software develop Software distribution Broad band operator Embedded device and handset Information security
Some impact will be seen in recent year, and others need 5 to 15 years. And some other impact we can not forecast currently, but certainly it will change the IT industry structure.
Cloud computing impact on server and PC
•Cloud computing revolution will increase the difference between server and PC. The servers will have the increasing performance requirement, maybe develop according the Moore's Law. But the PC not always have this requirement.•Servers will provide better support to hardware virtualization, remote management, power saving management. The performance of network and storage will improved greatly.•PC will pursue cost-effective and suitable to maintain agility, Cost-effective, convenient, low-cost. PC will not always pursue high performance or frequent hardware upgrade.•PC’s hardware and OS will give better support to broad band network.•At the same time, the difference of PC/laptop/netbook/mobile telephone will less and less, especially, laptop/netbook/mobile telephone will merge to a super terminal, this terminal have the performance and function of current laptop, but the size will be similar to telephone.
Cloud computing impact on chip industry
Cloud computing, with it’s impact on IT industry, will force chip designer and manufacture:
•Processor company support Processor virtualization and memory management•Network adapter and router/switch company support network virtualization better•Disc company support storage virtualization and capacity scale better•Network adapter support wireless broad band access better
Cloud computing impact on IT infrastructure outsourcing
IT infrastructure provider will have to implement:•Fast Provision•Reduce servers scale•Increase resource utilization rate•Improve management efficiency•Lower maintenance cost•Location of infrastructure in areas with lower costs of real estate and electricity•Provide business continuity service•Improve management efficiency•Improve service levels•Complex architecture•Change of business model and faith
Cloud computing impact on Internet application
After using infrastructure cloud, servers can scale automatically, storage resource can scale infinitely, database can scale infinitely, load balance can adjust automatically, it will be easy to build a large scale network application.Some Paas provider will make the task of deploy and sc
ale a network application to click some buttions.And with the cloud computing infrastructure service’s inc
reasing, Paas provider will arise more and more to conform infrastructure and application develop platform.
Cloud computing impact on traditional desktop application.
•With the rise of Paas and Saas, network application will be more and more, some of the Internet application can replace desktop application directly.•Applications based on browser can replace 90% of desktop applications in next 5years, but this replication is not obligatory.•Using remote desktop or desktop virtualization, all the desktop application can be on the internet, but is not obligatory.•The applications based on Internet will exceed desktop application in 8 years, and get to 80:20.
Cloud computing impact on SME IT department
The IT infrastructure investment of SME will decrease, the software company and Internet company’s initial hardware investment will decrease greatly.
Non-IT companies can not have IT department, or no need to have servers besides office computer, they can use standard or customized remote corporate database service.
SME can use few stuff, with using Paas and Sass service, to have large business.
Cloud computing impact on IT department of big enterprise
Big enterprise will experience three phase: use public cloud for non-critical business, use hybrid cloud for critical business, use public cloud for critical cloud.
The employees of IT department will have a little decrease, but only a little. Cloud computing will give cost-saving and management-convenient to companies, but there will be other problems to deal with because of cloud computing.
IT department can monitor the resource consumption of very business or department, and do internal capital settlement, and this will force the business develop and operation department to save IT resource.
Cloud computing impact on Paas
Cloud computing infrastructure service give many benefits, and the kind of these service will increase, there will be Paas provider to consolidate these service and shield the difference of different IaaS, to give more convenience to application develop.
Paas will drive midware market and software assemble pipeline.
Cloud computing impact on software develop
Cloud computing operating system will come, it will shield Iaas api and Paas service, form a uniform Cloud computing OS API.
It will be possible to develop auto-scale distributed software.
New software develop model will come with new programming language. The traditional memory scale, memory cache, server scale, database scale, storage capacity scale, backup will not be developer’s main problem, it will be resolved by Paas and cloud computong OS.
Cloud computing impact on software distribution
Saas model revenue will exceed license model revenue in 10 years, license model will only used in special industry.
Free and open source software with the service-pay model will increase.
Most of Opensrouce/Free/propriety software will be distributed online, cloud computing give great convenience for online sell.
Cloud computing impact on broad band operators
In the next ten years, broad band operators will need two major network device upgrades. The first are going, and will last for some years because of the fast develop of online video and SNS website. The second will take place five years later, cloud computing revolution produce more requirements on band rate and quality.
Broad band operators can provide IaaS service with IaaS provider, but they will fail to launch IaaS by themselves.
Cloud computing impact on embedded and handset device
Performance of embedded and handset device will be improved, but not infinitely, to be a suitable cloud client is enough.
Intelligent Mobile and laptop will mostly use IaaS. Intelligent Home Appliances will connect to Inter
net, people can control home appliances through Internet.
The size of Mobile Internet will exceed desktop-access internet. By the way, Mobile operators, broad band operators, mobile terminal manufactures will fail at trying to control Internet entry or content.
Cloud computing impact on information security
Antivirus and hacker will still be there. Cloud computing give convenience to standard client and client management, but this can not prevent attack action.
Antivirus model will change. Antivirus models based on virus database and virtual machine will exist, but the effect is not good.
There will be security search engine corporate. After the engine’s working, it will monitor the computer’s action and all the application and all the website pages, and it will analysis the applications and web pages based on it’s action throughput the whole network.
How cloud computing change the world?
Cloud computing as the third IT revolution, not only impact IT industry, but also deeply impact human society, such as:Most industry’s informationization and intellectu
alization will improved greatly.Human society will be a information-centric soci
ety.Information system will be the basic condition fo
r a company.The IT and information system can be migrated
to different providers.
Informationization and Intellectualization
Embedded device, sensor, artificial intelligence device will be use broadly in many industries.
There will be sensors and manipulator at the manufacture pipeline, instead of workers.
Robot will do all the dangerous work for human. Corporate will manage embedded device, sensor,
artificial intelligence device on cloud computing Iaas.
Human society will be a information-centric society
Every people will have two heads: body head and information head.
A major part of actions of the organization and corporate will be performed on Internet.
Network will be social infrastructure like water and electric.
Wireless broad band will replace mobile communication.
