Cloud computing definition
Cloud computing is a resource delivery and usage model, it means get resource (Hardware, software)via network. The network of providing resource is called ‘Cloud’. The hardware resource in the ‘Cloud’ seems scalable infinitely and can be used whenever.
Cloud computing and technology
New advances in processors, virtualization technology, distributed storage, broadband Internet access , automated management and fast, inexpensive servers have all combined to make cloud computing a compelling paradigm. This vast process power is usually got with a distributed, large-scale server cluster and server virtualization software.
What cloud computing means to service provider?
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
What cloud computing means to uSers?
Lower client workload
Lower Total Cost Ownership
Separation of infrastructure maintenance duties from domain-specific application development
Higher integratability
Not have to purchase assets for one-time or infrequent intensive computing tasks
Expand resource on-demand
Make the application have high availability
Quickly deploy application
Pay per use
Difficulties for cloud computing
Continuous high availability
Consistency
Interoperability and standardization
Scalability of all components
Data secrecy
Legal and political problem of data store and translation across regions
Performance issue
Difficulty customizing
Organizational obstacle
Architecture
Cloud architecture, the systems architecture of the software systems involved in the delivery of cloud computing, comprises hardware and software designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services.
Cloud architecture extends to the client, where web browsers and/or software applications access cloud applications.
Cloud storage architecture is loosely coupled, where metadata operations are centralized enabling the data nodes to scale into the hundreds, each independently delivering data to applications or user.
How does this benefit the companies?
The companies don't have to buy a set of software or software licenses for every employee.
Instead, the company could pay a metered fee to a cloud computing company.
Cloud computing gives these companies the option of storing data on someone else's hardware, removing the need for physical space on the front end.
The benefits of cloud computing include that it can minimize:
infrastructure costs
save energy
reduce the necessity and frequency of upgrades
lessen maintenance costs
Cloud application services or "Software as a Service (SaaS)" deliver software as a service over the Internet
It eliminates the need to install and run the application on the customer's own computers and simplifying maintenance and support.
