WHAT IS CLOUD COMPUTING
• Cloud computing is Internet-based computing, an Internet based computing environment where you pay only for resources that you use .
• A set of pooled computing resources delivered over the Internet.
• Resource allocation can be adjusted.
• Cloud Computing provides the infrastructures (both software and hardware) as services on a semi –permanent (rented) basic.

CLOUD COMPUTING - TYPE
Hybrid cloud – This system is a composition of Public cloud and Private cloud. It also use for transferring data from one to another cloud.
Public cloud – Suitable for applying to general systems not particular systems and serving massive clients and also cheap price.
Private cloud – Suitable for particular systems or needed high security systems through cloud provider.

INFRASTRUCTURE AS A SERVICE (IAAS)
Entire systems (virtual machines) will be provided to the users. Users can access the systems through internet Service providers charge based on the resource allocated
Access to infrastructure stack: Full OS access Firewalls Routers Load balancing

PLATFORM AS A SERVICE (PAAS)
In this model entire system along with the operating systems, software is provided.
Platforms are built upon Infrastructure, which is expensiveEstimating demand is not a science!
Platform management is not fun!

SOFTWARE AS A SERVICE (SAAS)
This one is more common Software created by service provider.
End users use these services on a subscription basis
No hardware or software to manage
Service delivered through a browser

CLOUD ARCHITECTURE
Individual users connect to the cloud
from their own personal computers or
portable devices, over the Internet. To
these individual users, the cloud is
seen as a single application, device, or
document.
The hardware in the cloud (and the
operating system that manages the
hardware connections) is invisible.Shailendra Singh

For those who follow trends in web hosting, cloud computing is a term that they come across often these days. There are many benefits of cloud computing irrespective of the size of the organization. The benefits include secure and affordable managed hosting, accessibility of data from anywhere at anytime, offsite backup, no need of internal IT resources, scalability and so on.
But there are some limitations as well since it is still an evolving technology. Some weaknesses of cloud computing are listed below:

LIMITATIONS
• Control of Data Security
• Hard to log for compliance
• Cascading effect
• Network Connection
• Large companies have internal cloud
• Dependent on service providers even for trivial applications.

CONCLUSION
• Cloud computing is a better way to run your business. Instead of running your apps yourself, they run on a shared data center. When you use any app that runs in the cloud, you just log in, customize it, and start using it. That's the power of cloud computing.
• Finally, cloud apps don't eat up your valuable IT resources, so your CFO will love it. This lets you focus on deploying more apps, new projects, and innovation
• Cloud computing increases profitability by improving resource utilization. Costs are driven down by delivering appropriate resources only for the time those resources are needed. ? Cloud computing has enabled teams and organizations to streamline lengthy procurement processes.
