Everything you need to know about Cloud computing.

1. What is cloud computing?

The on-demand, pay-as-you-go delivery of IT resources through the Internet is known as cloud computing. You can use technological services, such as computing power, storage, and databases on an as-needed basis from a cloud provider like Amazon Web Services (AWS) rather than purchasing, operating and maintaining physical data centers and servers.

Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service(SaaS) are the three main categories or types of cloud computing into which these services run.

A cloud can be either public or private. Anyone online can purchase services from a public cloud. With specific access and authorization settings, a private cloud is a proprietary network or data center that offers hosted services to a small group of users. Cloud computing's objective, whether it's private or public, is to offer simple, scalable access to computer resources and IT services.

2. Who is using cloud computing?

A wide range of use cases, including data backup, disaster recovery, email, virtual desktops, software development, and testing, big data analytics, and customer-facing web apps, are being used by businesses of every size, type, and sector. For instance, healthcare organizations are utilizing the cloud to provide more patient-specific treatments. Companies that provide financial services are utilizing the cloud to support real-time fraud prevention and detection. Additionally, online games are distributed to millions of players worldwide by video game developers via the cloud.

3. Types of cloud computing services.

Infrastructure as a Service, Platform as a Service, and Software as a Service are the three basic categories of cloud computing. You can choose the appropriate collection of services for your needs by taking advantage of the various levels of control, flexibility, and management offered by each form of cloud computing.

A. Infrastructure as a Service (IaaS).

the most fundamental class of cloud computing offerings. IaaS allows you to pay-as-you-go rent IT infrastructure from a cloud provider, including servers and virtual machines (VMs), storage, networks, and operating systems.

B. Platform as a Service (PaaS).

Cloud computing services that provide an on-demand environment for designing, testing, delivering, and maintaining software applications are referred to as platforms as a service. The goal of PaaS is to free developers from having to set up or manage the servers, storage, networks, and databases required for development to swiftly create online or mobile apps.

C. Software as a Service (SaaS).

You can get a full product through SaaS that is operated and controlled by the service provider. Most often, when individuals mention SaaS, they're talking about end-user applications (such as web-based email). You don't need to consider how the service is handled or the underlying infrastructure is maintained while using a SaaS provider. You only need to consider how you plan to use that specific software.

4. How does it work?

An internet network connection links the front end, which includes the accessing client device, browser, network, and cloud software applications, with the back end, which consists of databases, servers, and computers. The back end functions as a repository, storing data that is accessed by the front end.

A central server controls communications between the front and back ends. The central server uses protocols to speed up data exchange. To control connectivity between various client devices and cloud servers, the central server makes use of both software and middleware. Usually, each distinct application or workload has its dedicated server.

5. Top benefits of using cloud computing.

A. Cost

With cloud computing, there is no longer a need to invest in hardware, software, or the infrastructure needed to set up and maintain on-site datacenters, including server racks, 24/7 electricity for power and cooling, and IT professionals to oversee the infrastructure. It quickly adds up.

B. Speed

The majority of cloud computing services are self-service and on-demand, making it possible to provide even large quantities of computing resources quickly and generally with only a few mouse clicks. This gives enterprises a great deal of flexibility and relieves the burden of capacity planning.

C. Productivity

Hardware installation, software patching, and other time-consuming IT management tasks are frequently needed for on-site datacenters. Many of these duties are no longer necessary thanks to cloud computing, freeing up IT employees' time to focus on more crucial business objectives.

D. Performance

The largest cloud computing services are powered by a global network of safe datacenters that are routinely updated with the newest models of quick and effective computing gear. In comparison to a single corporate data center, this has several advantages, including lower network latency for applications and greater economies of scale.

BLOCK CHAIN: Introduction

 What is blockchain?

Blockchain is a mechanism for storing data in a manner that makes it impossible to change or hack.

A blockchain is simply a network of computer systems that duplicates and distributes a digital ledger of transactions across the entire network. Each block on the chain comprises several transactions, and each participant's ledger receives a copy of each new transaction that takes place on the blockchain. Distributed Ledger Technology refers to the decentralized database that is governed by numerous users ( DLT ).

In a blockchain, data is stored in blocks that are connected in a chain. because data connect in a chain so nobody can change or modify it.

As a result, if hackers try to hack a blockchain system, then he has to change every block in the chain which is not possible.

History of blockchain.

In 2008, Satoshi Nakamoto conceptualized the theory of distributed blockchains. He makes a special improvement to the design that makes it possible to add blocks to the initial chain without needing them to be signed by reliable parties. The updated trees would include a safe record of data transfers. It timestamps and verifies each exchange via a peer-to-peer network. It might be run independently without a centralized authority. These developments were so advantageous that they established blockchains as the foundation of cryptocurrencies. In the cryptocurrency industry today, the design acts as the public ledger for all transactions.

Blockchains have been steadily and optimistically evolving. In Satoshi Nakamoto's initial paper, the phrases "block" and "chain" were used individually, although they later gained popularity as one word, The blockchain.

by 2016. The blockchain file size for cryptocurrencies, which keeps track of all network transactions, has increased recently from 20 GB to 100 GB.

How does blockchain work?

Blockchain aims to make it possible to share and record digital information without editing it. A blockchain serves as the basis for immutable ledgers, or records of transactions that cannot be changed, removed, or destroyed. Blockchains are also referred to as distributed ledger technologies because of this we also called it (DLT).

You can easily understand it's the mechanism by these steps.

1. Record the transaction.

2. Gain consensus.

3. Link the blocks.

4. Share the ledger.

What are the benefits of blockchain?

Blockchain technology brings many benefits. In the subsections that follow, we list some of them.

1. Advance security.

Modern digital transactions require a high level of security and trust, which blockchain platforms offer. A constant worry is that someone may alter the underlying program to create fictitious funds for himself. Contrarily, blockchain leverages the three principles of decentralization, consensus, and cryptography to build a very secure underpinning software system that is virtually impossible to alter. No single point of failure exists, and only one user is unable to alter the transaction records.

2. Improved efficiency.

Business-to-business transactions can be time-consuming and lead to operational bottlenecks, particularly when third-party regulatory agencies and compliance are involved. Such commercial transactions are quicker and more efficient thanks to blockchain's transparency and smart contracts.

Conclusion.

No little part of the reason why blockchain is finally gaining recognition is due to bitcoin and cryptocurrencies. Blockchain, a buzzword on everyone's lips as an investor in the country, promises to reduce middlemen while increasing accuracy, efficiency, security, and cost-effectiveness in commercial and government activities.

Cyber Fraud : An exponential threat to Digital India

AS the numbers of cases registered are increasing the primary question rises whether the Online systems are secure or not? the Answer is simple we need to be more careful and systems are there but in 90 % cases the fraud happens due to the negligence and ignorance of users. To minimize the threat and safeguard from these fraud there are some basic and best practices which we will discuss in our next blogs.

Smart work or Hard work

The topic is not so much controversial and anybody would say both are required in your path to success but when to work hard and when to work smart that is the tricky part and it makes all the difference between success and failure.

As I remember myself back in the day I preferred to work smart and hardly did any hard work but whenever I was working smartly I put a lot of hard work in that smartness. I know this is oxymoron language and anybody would say now " कहना क्या चाहते हो भाई ?"  so let me share you my experience. Back in my memorable training days in Infy Mysore one of the session was how to work smart and he said when client gives requirement first search if the solution is already there then don't waste your time to do something which is already done. Hard work is needed when you are doing something novel and unique. So apply this funda in your day to day life also and see how smartly you can achieve what you are aiming for.

Still have some doubts then refer these lines: " Choose the Lazy person to do the hardest work and he will smartly find the easiest way to complete it."

Success is not the destination Its a Journey

I thought of venting my feelings and giving them the words so no better place than to write a blog about it but before I could start It took me two hours to reach the starting. Before typing anything I got stuck with the title.

As of now while I am writing these lines I don't have the title but eventually we will find it before we end this blog. If you are thinking who is the other one in this "WE" then it's none other than I and my writing.

So after skipping the title I thought I must start with some phrase or motivational stuff but then again confusion of selection. now in this era of information (or we should say data) its so hard to compile something useful from this haystack and quite a task to perform.  So later on I decided to write some answers on quora before writing something here. But there are so many questions and again so much confusion for whether this question should be answered or not.
 
So I am back to square one and here we are stuck with lack of title and content. So after retracing my thought process that the idea of writing the blog today occurred to me due to the lines I came across reading today which are " With so many things coming back to trend I am waiting for MORALS, RESPECT and INTELLIGENCE to trend again ". and apart from these things I hope the amount of time spent on social media today to spread information will be saved from circulating rumors. The youtube has the data to watch which can't be completed in a single lifetime.  Why people are so obsessed with making money through Tiktok or other video status app? 

I might be sounding like someone who is judging everyone for their actions but believe me when I say we are wasting a complete generation and there is no way to stop these things. Anyways that's the beauty of writing you start with no idea where it will go but eventually you will find the road and reach the destination once you start. Let me conclude here with these fabulous lines  from Mirza Galib (Image: storypick.com):

Goal of the Year...Happy 2018!!!

Don't know how to start and yet it's already begun. Sometimes the dilemma of your mind don't allow to clear the blur of future vision.  Why we contemplate so much.

When you decide to stop thinking or actually you are trying to stop(hold yourself) for thinking. anyways if I myself won't understand then how I will convince others for the same. 

As the title suggests the goal of 2018 is to be happy.

here are few tips which I will follow to do the same:

1. Speak less listen more.

2. Whenever having the rush of thoughts stay calm and don't spit it to everyone.

3. People are good listener but not everybody is a good adviser. 

4. Listen to your heart. Mind will never support the illogical ideas which gives you happiness.

5. Last but not the least Never Judge anyone in any condition.

I think one can't follow more than this. These are more than sufficient steps to stay away from trouble and have a happily ever after feeling.

Till the next post... Adios Amigos!!!!!!!

Hi All,

Today I am writing here about converging technologies of Information Technology which will make noticeable changes in field of data analysis. Sparse technology is also known as "thin data processing technology" is the next big thing in  the field of IT. The definition of data has been changed now days and information supplied to system through Non - IT sources are so much valuable and bulk in size. Sparse Technology is the method to process and generate new information from that data.

So people in IT who are looking to learn new technologies should look up for this.
