What is Virtualization in cloud?

In this post, we will discuss Virtualization, load balancing, Hypervision, and Machine Imaging





What is load balancing?


In simple terms balancing traffic in an appropriate and effective way is called load balancing.
Example:-
Suppose you have a website and your gateway can handle 1000 visitor at a time but traffic is 2300
what will happen to your gateway? It will stop working and your website may crash.
This is called load and if we manage this using more gateways it will be called load balancing.


Real-time Example:-
Flipkart hosts sale on   22 July 2014 and Site "Crashed"
Do you know why?
Because the traffic was more than expected and the gateway failed to process
The error was 5001,5002,5003 which refer to gateway and service unavailable.

How to overcome crash and the answer is to buy more gateways and handle the traffic.

let's understand it with a simple example
You have a website whose daily traffic is 1000 visitor and on sale, your traffic reached up to 10,000 visitors.
You won't buy a new server or gateway for that what you will do is,
you will rent gateway and you will handle the traffic, it's the cost-efficient and right way to process the traffic. It will be a virtual and the user can access it anytime.


Now, What is virtualization?

Virtualization refers to the creation of a virtual resource such as a server, desktop, operating system, file, storage or network.

Real-time example
If you wanna use the android game in pc what will you do?
You will use bluestacks

What is Bluestacks?

It's an emulator which help you to run mobile apps.
 it will provide you with a virtual platform to access the apps.












Example 2

We use Software for installing 2 operating system (window 7,8, Linux etc)in single PC
its virtualization and the software is emulator which help the user to get a virtual experience.



 The hypervisor is the emulator 
 which support virtualization and through virtualization load balancing is done.

What is BlockChain ?

The blockchain is a chain of blocks which contain information. First used in Bitcoin by " Satoshi Nakamoto " in  2009 for Bitcoins(A digital currency) The blockchain is a distributed ledger.

According to Wikipedia ledger is A  ledger   is the principal book or computer file for recording and totaling economic transactions measured in terms of a monetary  unit of account  by account type, with  debits and credits  in separate columns and a beginning monetary  balance  and ending monetary balance two account. In simple terms a file which stores information like transactions and account details called Block and the connection between them is Chain. A block contains 3 part  Hash of the previous block Data Hash   Block of Blockchain Hash is a  like a fingerprint, which contains details of data(sender, receiver, content, previous block hash etc) Hash looks like this "a 0680c0...

What is Big Data?

Big Data is the huge amount of data which can't be stored and processed using the traditional methods within the given time frame. So, The Question arises that how much big should be the big data . Generally, people think that the data whose size is more than GB, TB, PB is big data. But, it's not the case. some data which is small in size can be a big data. For example 100mb of a document is to be sent by email(we generally use Gmail ), but it's not possible because Gmail  doesn't support this feature.  That's why  100 MB of the document can be referred to as a big data for email service. let's understand bigdata with another Example 1TB of data is given a person, 1 TB contains images which he has to edit and process in a particular amount of Time, for a normal user it will be a Bigdata. Some analysis of data in the real world Facebook-100TB /day twitter- 4400 twites /day LinkedIn - 10TB/day Google+ - 10TB/...
