Many ITs when trying to dive into Cloud world for the first time, they got lost, we cam sum the below simplified points to understand this technology in an easy way:
1- Computing:
Basicly means VM, whether it is OS like Windows, or a virtual Router, or Firewall, or any other VM, the basis here is ( CPU & RAM ), It is basicly as you were going to buy a computer from a store, which is the Cloud in our case, you must specify CPU & RAM. What about the hard disk.. Continue to the second point.
2- Storage
Here you will choose the type of hard drive, whether it is SSD or HDD. Now, What about the motherboard, here the cloud roles as a main board.
Now that computer, device, or anything that we called VM Virtua is ready to work, but now I should secure the network which will connect this computer to the Internet or connect it to other servers inside the cloud.
3- Network
Here there are NAT/DNS/ Loadbalance/Subnet/ and other networking matters.
4- Application
After completing the servers in the first and second points, and the third point was networked. Now the application is installed, and here the application can be a Web-site, or programme. Of course, every application has parts, and the most important of these parts are Data base / Web server and other matters related to applications.
5- Security
Finally, the security will be present in all the points above, with many complexities.
So, to summarize, when you start learning the cloud, keep those points in mind and classify everything you see there under these points:
Computing / Storage / Network / Application / Security.
