Let's know about Cloud Computing

To understand the cloud, let’s talk about the computer in your home. It is primarily composed of 3 things. A storage system for storing data. Some chips on the motherboards to perform tasks (tasks like moving data around or running some algorithms), and a user interface device to show the data to the user (computer monitor) through which the user can interact with the system (keyboard and mouse)

The first thing that people started needing more is storage capacity. Back then, like 7 years back, you probably had more external hard drives than you had computers in your home. Cameras started to increase in megapixel count, and all those home videos of birthdays and family trips on digital video cameras needed a lot of space to store.

Managing hard drives and worrying about backups in case they failed were a constant headache. If you ever bought Seagate hard drives, you already know.

Then Dropbox came along where you could buy some storage space online and upload your files to Dropbox. They maintained backups so you didn’t need to worry about losing your data or keeping manual backups. They appeared as another drive on your computer just like if you had plugged your external hard drive in.

No more external drives to manage or USB cables to wrangle or running external power supplies. Your data on someone’s else servers under your name.


That was storing data on the cloud

The one thing you worried about was security and that has come a long way. We’ll talk about that later in this article.

Today we pay $1/month for 1TB of data to Google to buy storage on Google drive. A 1TB Western Digital hard drive would cost about $55. That’s buying 4 years worth of storage on the cloud for which you don’t need to worry about backups, hard drive crashes, or worst — the problem of whatever version of windows would be there 4 years from now not recognizing your USB drive anymore!

While consumers started offloading their storage to the cloud, companies started thinking about how to offload more than just their data.

How it all began?

Though the internet was born in the 1960s, it was only in the 1990s when the potential of the internet to serve business was discovered, which then led to more innovation in this field. As the transfer speeds of the internet and connectivity got better it gave way to a new type of company called Application Service Providers (ASPs).

ASPs took the existing business applications and ran them for the business using their own machines. The customers would pay a monthly fee to run their business over the internet from ASP’s systems.

But it was only in the late 1990s that cloud computing as we know it today emerged and led to this blog on what is cloud computing.

And since it has only grown, recently business insider reported,

The cloud computing service has grown nearly 80% year-over-year in the last two quarters and is on pace to hit $7.8 billion in revenue in 2015, four times the 2012 sales of $1.8 billion.


We now know about the service models, once you offer a service next comes deployment, let us now discuss the deployment models:

  • Public Cloud
  • Private Cloud
  • Hybrid Cloud

Public Cloud

In a public cloud deployment model, the services which are deployed are open for public use and general public cloud services are free. Technically there may be no difference between a public cloud and a private cloud, but the security parameters are very different, since the public cloud is accessible by anyone there is a more risk factor involved with the same.

Private Cloud

A private cloud is operated solely for a single organization, it can be done by the same organization or a third-party organization. But usually, the costs are high when you are using your own cloud since the hardware would be updated periodically, security also has to be kept in check since new threats come up every day.

Hybrid Cloud

A hybrid cloud consists of the functionalities of both private and public clouds. How?

Let’s understand it through an example: Suppose there is a research company, so they would have some published data and also, data which would still be in the research phase. Now anything which is still in research should be kept confidential right? Though your cloud provider may have state-of-the-art security features then it is still open to the public, therefore prone to cyber-attacks.

So to address this risk, you can keep the data still being worked on, in your company’s servers whose access is controlled by the company, and your published data on the public platform, this type of arrangement would be a hybrid cloud.

I think by now you must have a fair idea about what is cloud computing. Let’s go ahead and know the target audience of the cloud, that is YOU, now you can either be looking at the cloud as an individual or a business, let’s take an insight into both perspectives.

Blockchain = Block + Chain = listOf(block)

Image
The concept of blockchain technology is set to revolutionize not just the finance or healthcare industry but many aspects of business, government and even our personal lives. The problem is that there is so much hype and misunderstanding out there, which made me take a step back and explain the basics of what blockchains are and how they work — in a very simple way, that hopefully, anyone can understand, even with no prior technical knowledge necessary. Blocks in the blockchain consist of digital pieces of information and specifically have three parts to them: They  store information about transactions  like the date, time, and the amount transferred They  store information about participants . For example, it will contain information for your purchase from Amazon on a record with your name along with Amazon.com. But instead of using your actual name, your purchase is recorded without any identifying information, it is referred to as “ digital signature ” and is sort of l...

AI a revolutionary invention

Image
  The concept of intelligent beings has been around for a long time. The ancient Greeks, in fact, had myths about robots as the Chinese and Egyptian engineers built automatons. However, the beginnings of modern AI has been traced back to the time where classical philosophers’ attempted to describe human thinking as a symbolic system. Between the 1940s and 50s, a handful of scientists from various fields discussed the possibility of creating an artificial brain. This led to the rise of the field of AI research — which was founded as an academic discipline in 1956 — at a conference at Dartmouth College, in Hanover, New Hampshire. The word was coined by John McCarthy, who is now considered as father of Artificial Intelligence. Despite a well-funded global effort over numerous decades, scientists found it extremely difficult to create intelligence in machines. Between the mid 1970s and 1990s, scientists had to deal with an acute shortage of funding for AI research. These years came to ...
