Hello everyone, My name is Gulshan Negi and i am in the third year of engineering and want to learn Cloud Computing from the scratch, I know cloud computing is the future and many of the small and medium, and large organization are using the cloud and I want to make my career in the cloud computing, so Cloud Computing can be divided into public (ie you rent service from a provider), private (run within a company) and hybrid which is a mix between the two. What is the difference between private/private clouds compared to just running a standard LAN (local area network) within the company? Or is it the same thing?

There are two distinct items here: The computer servers that make up the "cloud", and the communications network that passes data from where you are to wherever the cloud servers are located.
- The servers typically consist of many general-purpose CPUs =Central Processing Units, with large amounts of RAM=Random Access Memory, coupled with lots of disk space, and connection to a communications network (LAN and/or WAN).
- The number of computers dedicated to one task can change dynamically, as the workload changes
- Sometimes specialised processors are available which do things like run Artificial Intelligence models or high-powered number crunching or high-speed encryption.
- A "LAN"=Local Area Network is a communication network within a building. It may have traditional blue Ethernet cables, or, increasingly, use WiFi to connect to your phone or laptop. You use a LAN to reach a local cloud (eg in the same building, run by your company)
- A "WAN"=Wide Area Network is a communication network between buildings. It may have traditional telephone wires, optical fiber, or, increasingly, use 5G mobile to connect to your phone. You use a LAN to get to the edge of your building, and a WAN to reach a public cloud (eg in a Data Center in your city; it might be run by a cloud provider like Amazon or Google)
-Your company can rent space in a public cloud, and let the cloud provider look after the hardware, air conditioning and power supplies. Or it can buy its own hardware for a private cloud.
- But if you need fast responses ("real-time"), you will locate the servers closer to where you are, as there are delays inherent in passing over a LAN or WAN; these delays generally increase with distance.
If you want to get into cloud computing, you should do some general courses on software, and some specialised courses on cloud computing (each cloud computing vendor has their own unique software environment).

Hi,
Whatever is media or server location, administrating it's admission gives (private/vs open).
Cloud introduced in order to increase effectiveness if hardware sharing
Wireless technology encryption is must have, the signal cannot be captured/deciphered.
You might also try open courses to have an insight from scratch.
e.g. Coursera, EDX, etc.

Does that mean a mimicked super cray (by large/huge numbers of PC's) is a cloud?
If it does classify as a cloud, the brain is a complex organism considered one of the most powerful computers,
so too, is it a cloud if it is a narcotics addicts brain?

This means, that somebody stores super-computers and provides you as much of storage and computing facilities as you need. Hence, there is no need to by your own super-computer, when half of it power/ storage you will never need to use.
Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping you lower your operating costs, run your infrastructure more efficiently, and scale as your business needs change.

the Internet (“the cloud”)
That's unusual, because I always assumed that "The Cloud" was the data center with its servers; the internet, was the way you contacted the data centers.
- Wikipedia follows my way of thinking
- While Microsoft Azure uses your way of phrasing it. But maybe Microsoft also sells a lot into homes, so they see the home computers being part of the cloud?
- Or maybe I just misunderstood the phrasing?
People who conscript home computers into mining for bitcoins (they use your electricity to benefit the hackers) or botnets for Denial of Service attacks certainly view home computers as a resource to be harnessed!
- The coming wave of "Internet of Things" devices will also be another resource that some people will attempt to take over..

Hi, I think this is misunderstanding, yes.
Wikipedia: Cloud computing
https://en.wikipedia.org/wiki/Cloud_computing
Cloud computing is the on-demand availability of computer system resources, especially data storage (cloud storage) and computing power, without direct active management by the user.
"The Cloud" was the data center with its servers; the internet, was the way you contacted the data centers.
When I used 'somebody' - that probably brought the misunderstanding. Google, Microsoft..
People who construct something at home for themselves the opposite, I would say. IoT has nothing to do with determining Cloud computing for the definition.
Thank you.
