CLOUD COMPUTING
UNREVIEWED SUMMARY:

When we say "Cloud Computing" we mean storing and accessing data through internet, instead of saving them to your hard drive.
There are three different types of cloud (Public, Private, Hybrid):
1- public cloud:
Public clouds are based on the standard cloud computing model, they provide spaces for several businesses' resources on one server, where if any of the businesses are hacked, then other businesses are at risk. The public cloud may be free to use or offered on a pay-per-usage model. It is easy and has a low-priced set-up because hardware and sotware costs are covered by the cloud owner. So, no resources are wasted because you pay for what you use.
2- Private cloud:
Private clouds store cloud resources as private. They can be ideal for private companies that cannot host their resources on public cloud. Because it is important to keep the data is a safe place, in order to save data. For example, private companies, and hospitals must have their data in a private cloud . So private clouds are not suitable for all buisnesses. But they still provide the same basic benefits of the public cloud. They also have some disadvantages. For example, it is more difficult to access the data that is held in a private cloud from remote locations as a consequence ot the high security measures.
3- Hybrid:
Hybrid cloud is a cloud computing enviroment that uses a mix of on-premises private clouds, and third party public cloud services with composition between the two platforms. It allows businesses to be more flexible and gives more data deployment options. This is all by allowing workloads to move between private and public clouds. Hybrid clouds can present challenges, as their workloads must approach and join public cloud providers, so it requires API empathy and solid network connectivity.

There are three main categories of cloud computing:
1- Software as a Service(SaaS):
It is a software model that has been used to distribute third party provider hosts applications, and makes them able to be shown to customers on the internet. Google is the most well-known example
2- Platform as a Service(PaaS):
Used to design, build, and test applications that are provided by the cloud structure.we have Google App Engine as an example of (PaaS).
3-API as a Service(IaaS):
Provides services like storage, database, and computer capabilities. Amazon web Services is a very famous website, it is an example of API.

There is an unlimited number of cloud computing applications.Users can access it through any computer or device that is connected to the internet. The most widely-known applications of cloud computing are Dropbox , Amazon Web Services, Google Compute Engine, and google docs,etc..

There is an unlimited number of cloud computing applications. This is beneficial because clients would be able to access their applications at anytime and anywhere; they can access it through any computer or device that is connected to the internet. The most widely-known applications of cloud computing are Dropbox , Amazon Web Services, Google Compute Engine, and google docs,etc..

My questions about cloud computing:
1- Can we replace cloud computing with anything else?
2- How can I make a cloud by myself?
3- Is it important as Artificial Intelligence?
