HOW CLOUD COMPUTING WORKS


HOW CLOUD COMPUTING WORKS ?






What is cloud:




  A cloud is like a server which communicates with other computers over a

network such as LAN,WIFI etc. What normally a  server does is,it  hosts files of  the user and 

manipulates data according to instructions given to it and the returns the data to the user.





 When internet is first interduced, people used to use there

own computers as servers ,but when net users increased during these past 50 years

it became difficult for a individual or small organisation to maintain their own servers ,as it costed

them more (to maintain servers for power,firewalls,equipment,workers, maintenance etc) than

income they got. Due to this web business reached loss,then they used large computers to maintain

data,but this too failed due to increased users and cost to maintain those equipment,then they thought

of a idea that could make possibility for  users to use  applications without buying them from

vendors,without installing them,without maintaining personal servers and they could access those

 files from any computer . This idea is nothing but cloud.


Formal definition:
  

                Cloud computing is a type of computing that relies on sharing computing resources

rather than having local servers or personal devices to handle applications. This is formal definition

as far as i know.


Let me explain cloud with a example.
          
              
                 Suppose you own a company and you had a server to maintain 10,000 TB data and

several softwares your staff to work, but you couldn't maintain the server because your income is

1,00,000 per month server maintenance costs you 1,20,000; obviously you will run  into loss,so

what to do?

The answer is go to cloud.


So what does cloud  to solve your problem?
          

                  Cloud takes all of your data keeps it in its own location. Then it gives access to those

data to you. So you and your staff can access to the data location and work on it(this is simple as you

access from your own server) do from your own server. Cloud supports logging to that data from any

place,any time,any method and any number of users but to have to pay the vendor(if you get 1,00,00

every month you have to pay 10,000 to 20,000), it rises only one problem,that is,is your secret files

are open to all (though they are secure but thee is is possibility of accessing data by the vendor on

severe circumstances).
              

                  If you still couldn't understand let me give a simple example, you are familiar with

Facebook(every one knows), Facebook takes data such as photos,friend names etc.You just have

to use username,password to login to your data don't have the data (posts,photos,friends,

comments etc) with you .

so how it is possible?
              
                 Answer is simple. Facebook is a kind of cloud which maintains all your data,your friends

and stores it in a place (cloud) and when you log in it links your data to other according to instructions,

but you never installed a program for that  These programs are supplied by Facebook and are used to 

access your data without installing any software,This is what cloud does.



The complete function of cloud is this, a cloud takes softwares from various companies and

maintains it in a place. Users who have access can log in to that data and use it, but you couldn't own it.

You need to pay little amount for it,(instead of paying huge amounts to maintain those data)

,advantage is you need not maintain servers that cost much,no need to buy costly softwares ;just rent

it,no need to maintain strong firewalls to your data.


Advantages:

                        
 1. No need to maintain servers to keep large data.

2. No need to maintain firewalls.

3. No need to buy costly equipment.

4. No need to own large place for offices or business.

5. Business or office can be easily shifted from one place to other.

6. No need to buy costly softwares,firewalls,renew it and all ths nonsense.

7. Capacity of working data,staff can be increased or decreased just in a single

click or a phone call.

 8. Instead of having small firewall to protect from hackers, a firewall with strong

surveillance can be used.


Disadvantages:


1. Your secret data will be open to government,private people.

2. You could not own anything.

 3. Internet connections should be very fast(not a big task to companies).

4. No cracks can be made for softwares(poor college students).



Conclusion:

           Cloud can fulfill dreams of small companies to maintain data as big companies,can show

hope for unemployed and show new path for developers. Data could be securely organised without

any tension.Future with cloud can bring a lot development in ICT (Information and communication

Technology)sector.



Freshen Up Your Home While Vacuuming with Oils and Cotton Balls





Vacuuming is nobody's favorite chore, but when you have to do it, you should at least kill two birds with one stone by taking the opportunity to make your home smell great.
All you have to do is soak a few cotton balls in your essential oil of choice, and drop them in the vacuum bag before you start cleaning. 


The cotton balls will infuse the air ejected by the vacuum with the scent of the oils. The effect will be subtle, but it's so easy to do that it's worth trying every time you vacuum. 
If your house really smells bad, you can cook your leftover oils in the oven for an hour or so to fully infuse your house with a pleasant scent.

Linux Directory Explained



Linux and Unix file system is defined by 'Filesystem Hierarchy Standard(FHS)', If you are a complete windows user and are new comer to linux based OS like Ubuntu or Fedora then the file system structure of linux may look alien with all those cryptic named folders.

In this post we will go in to great detail explaining the file system structure of linux. To this particular post we will be using Ubuntu as the base and even if you are using other linux based OS, the file system will mostly be similar to Ubuntu, So no worries.

Note: Ubuntu may also contain files and folders which are not yet included in FHS.          EX: /cdrom



Linux Filesystem Hierarchy Standard


/

This is the root directory of your linux box, typically every thing goes from here. This is something like C drive of your windows machine.

/bin

/bin directory contains essential user binaries which are required when the system is mounted in single-user-mode. Don't get this confused with /usr/bin where user specific applications like compiz or firefox are stored.

/boot

The name says it, Here the static files like GRUB and linux kernels required to boot the system are stored.

/cdrom

In simple this is the temporary location for CD-ROMs inserted in to your system. As mentioned above this is not part of FHS but you can see it in Ubuntu and other linux based OS's.

/dev

The /dev directory contains all the device files. In linux world, everything is seen as files and folders including your hardware. For example you can find your hard drive under '/dev/sda' and cd-rom under '/dev/cdrom', etc.
This drive not only contains physical devices but also contains virtual pseudo-devices.

/etc

/etc contains system wide configuration files which can be edited using simple text editor. It does not contain user specific configuration files as they are situated under each user's home directory.

/home

The /home directory contains the home folder of each user. Each user has write permission to his/her folder only and must obtain elevated permission to modify system files.
Each users home folder contains user-specific-config files and data files.

/lib

The /lib directory contains library files which are used by the binaries in /bin and /sbin directories.

/media

The /media directory contains sub folders of mounted removable media. For example, if you insert some usb stick or cd-rom then you can see a folder mounted automatically inside /media directory.

/mnt

Simply speaking this is the temporary mounting point for system administrators to mount other file systems like windows.

/opt

This /opt directory is used by propitiatory software packages which doesn't follow FHS.

/proc

This is the directory which contains files representing system and process information and basically it is very similar to /dev directory.

/root

To be simple, this is the home directory of *root* user. It contains data and config files of root user. Unlike normal users whose home folders are situated in /home/user, Root users have their home folder directly under /root directory.

/run

This /run directory contains application state files which provided application to store their transient files required like processes ID and sockets.

/sbin

This /sbin directory is actually similar to /bin directory but contains system administration binaries which are generally intended to run by the root user.

/selinux

This directory has nothing to do with Ubuntu as Ubuntu doesn't use SElinux. Actually /selinux is used to store security related files which is also similar to /proc directory. SElinux is used by other linux distros like Fedora and Red Hat.

/srv

/srv is defined as the directory containing the service data.

/tmp

The /tmp directory contains all the temporary files of running application which are deleted as soon as the application is closed or after some interval.

/usr

The /usr directory contains user binaries and other read only data of specific user and not the system specific binaries or data.
There are other sub folders in /usr directory like /usr/local where locally compiled applications are installed, /usr/bin where non-essential applications are installed, /usr/sbin where non-specific system administration binaries stored.

/var

To be simple this is a writable version of /usr(which is read-only) folder which contains variable data files like logs files.

Windows 8 Fix :This user wasn’t added to this PC. Code: 0xd0000225
