The Cloud model is composed of 5 Essential Characteristics, 3 service models, & 4 deployment models.

 A) The 5 essential characteristics are as follows:

• On-demand self-service

• Unlimited  network access

• Resource pooling

• Location independence

• Rapid elasticity

• Measured service

 B) The 3 service models are as follows:

•  Cloud Software as a Service (SaaS) — Use provider’s applications over a network.

•  Cloud Platform as a Service (PaaS) — Deploy customer-created applications to a cloud.

• Cloud Infrastructure as a Service (IaaS) —Rent processing, storage,network capacity, and other fundamental computing resources.

 C) The 4 deployment models, which can be either internally or externally  implemented,are summarised as follows:

•  Private cloud-Enterprise owned or leased

•  Community cloud-Shared infrastructure for specific community

•  Public cloud-Sold to the public, mega-scale infrastructure

•  Hybrid cloud-Composition of two or more clouds

In Next post we'll explain it in Detail. Hope you liked the post , Please do drop your responses and share with your friends.  

Now the cloud is simply the latest and fashionable term used in industries today for Internet,though Internet may be foundation for the cloud but it more than Internet .In cloud we can used the service whenever we needed and as long as we needed we do not need to install any application on the Desktop,and we need not need to pay for the service when  we are not using it.

Note: We can call Internet as the cloud but every time cloud cannot be called as a Internet

WAY 1:

There are several sorts of  Cloud Computing Model for

        a) PUBLIC CLOUD  
        b) PRIVATE CLOUD
        c) HYBRID CLOUD

 THE FOLLOWING ARE THE MAJOR 9:

  1)  IaaS – Infrastructure as a service
  2)  PaaS – Platform as a service
  3)  Saas – Software as a service
  4)  Data as a service
  5)  Desktop as a service
  6) Storage as a service
  7)  Test environment as a service
  8)  Security as a service
  9)  API as a service

 BUT THE 3  MOST SUCCESS FULL MODEL FOR BUILDING AND WORKING

 PRIVATE CLOUD, PUBLIC CLOUD,HYBRID CLOUD




In this model of cloud  of (IaaS), which is the most basic, the providers of cloud offer computers, in the form of physical or  more like the virtual devices, along with other resources. The virtual devices are run by hyper visor as guests, like KVM or Xen. The hyper visors pools management by the OSS (operational support systems) of cloud  to direct the capability to scale for supporting a huge number of the virtual machines. The other resources that are in the (IAAS) clouds are  the images in the virtual machines image library as well as file-based storage's, load balance's, firewalls, VLANs (virtual local area networks), IP addresses, and bundles of software. depending on demands from their huge pools that are installed in the carrier clouds, which is the dedicated private virtual networks that can easily be configured.




The fact of cloud computing claim that it allows the enterprises getting their apps up & running faster, improving the manageability while requiring less maintenance. It also enables the information technology to adjust resources more rapidly for meeting the unpredictable and fluctuating business demand.

WAY 2:

 Now Cloud computing is divide into 2 ways

           a) FRONT END 
           b) BACK END





a)Front Ends Include: Clients computers Consists of network application that user will
use for interface to access the back end of the system.(now each application in network
varies from one another and play there specfic role for the client to access the network)

b) Back Ends Include: Computer server, Data storage system router,switch,
and other networking  device which comes under cloud section of th system.
Basically the back end is accessed by the public through internet mostly operted through
single or multiple location supported by the ISP (INTERNET SERVICE PROVIDER)
Cloud Computing system maintain the communication between both which require
various (Networking application,Protocols,System software as the middle-ware).
through with it moniter various request from client,s and maintain the traffic
between both end's and maintain the communication.

WAY 3:

Let's simply equate cloud computing to the Internet,cloud allows us to access application that actually reside at location other than our computer or Internet based service simply we can say DISTANCE  DATA CENTRE.

Lets say we are executive of corporation and our job is to make sure all employee
should have right (Hardware and Software) to their jobs.now buying Hardware isn't enough we have to purchase software or software licenses to give employee proper tool for their jobs.now here we set up software distribution server which automatically install application on client machine.
    Now every single time if a software we are using issued a service pack or patch
    we also had it install it through(DVD-ROM OR CD).or through Distributed server
    to distribute it, Now here don't forget the cost all license of service pack or patch.
    that will led organisation in huge pile of money.

   There is alternative for this.Instead of installing a suite of software for each computer
   we will load only one application, that would allow employee to log the application to
   web service like (Firefox or opera) and complete there jobs.now this application will
   perform all complex job role as we require, depending how we craft the service.

  The beauty of cloud is that other company host your application,this means
   they will handle the costs of server, they will manage the software update depending
   on how we craft our contract...now Don't forget the cost of hardware we won't need
   to buy. nor pay for electricity for colling down the Data Centre this will save our capital
   expenditures.

 EXAMPLE:

a)If You walk into a Cyber cafe or library and sit down at any computer without the preference of operating system and access browser as our service that service is said to be as Cloud-Based Service.  
                                                        OR
 b)If You have a E-mail account with Web-Based E-mail service like(YAHOO or GMAIL) then You  are using cloud.Instead of running a E-mail program on our PC,we simply log into Web E -mail account remotely  the software and storage of Your account doesn't exist on Your computer it's on cloud.



Please Leave your responses/queries . They are precious for us.

In our previous article "Cloud Computing Defined in 7 Ways"we gave you basic idea on cloud computing now we'll little deeper into the concept.


So Lets begin , In simple topological sense cloud computing components is made of  several element such as

a) Clients

b) Datacenter

c) Distributed server

a) CLIENTS

          

b) DATACENTRE

 

c) DISTRIBUTED CLIENTS

 

Cloud computing is everywhere. Pick up any tech magazine or visit almost any IT
website or blogs and you’ll be sure to see talk about cloud computing. The only
problem is that not everyone agrees on what it is. Ask ten different professionals
what cloud computing is, and you’ll get ten different answers.

Even it is worth for such hype lets see........................

                                            WE CAN DEFINE CLOUD AS

 a)The service is accessible via web browser or web services.

 b)Zero capital expenditure for hardware and software  to get started for business.

c)pay as you go service i.e you pay for what you used.
          






                      BUT  TECHNICALLY WE CAN DEFINE CLOUD IN 7 WAYS.

1) Cloud Computing is transforming the business to increase efficiencies while reducing the cost.

2) It is Metaphor for Internet (Internet is referred as network diagram as cloud).

3) Application running on hosted server as the services.

4) Cloud Computing is model for convenient on demand access to a computing Resource
   (networks, server, storage, application and service) that can be made available by service provider  from computing resource pool.

5) We can also refer as accessing software and storing data on Internet.

6) We can also refer as the modern version of time sharing model.
                                                             
7) We can also  define on 5 attributes as
                  - Shared resource
                  - Elasticity
                  - Pay as you Go Service
                  - Self provisioning and scalability).


At last it make the it department to focus on strategic aspect rather than keeping the Data center running.

We are back again with new topics to discuss on, that is 5 best compressing tools for Windows and Linux Users. The Compressing/Archiving  tools, without which drives in our PC/Laptops would be bottle necked. These tools have made our life easier than before by saving an effective amount of precious storage space.


Getting on to the point , Today we'll be discussing Best Freeware/Shareware Compressing/Decompressing tools for our users, lace with Windows/Linux OS. Those tools are as follows.

• 7-Zip  

• PeaZip 

•  FreeArc 

•  WinRAR

•  Universal Extractor

   

 

7-zip (Freeware):

 

               7-zip ranks first in our top 5 list as there is absence of all useless and extra elements in its UI. besides its UI,  it supports variety of packing/unpacking formats like 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM with incorporation of AES-256 bit Encryption to ensure Tight Security for your files. Also provides integration with windows shell and command line support too.


Supported OS: Windows, Linux, Mac.

PeaZip (Freeware)

 


             On Second ranking comes Peazip , similar to 7-zip it is  again freeware tool with good, clutter free User-Interface . Talking about formats supported , it supports about 150 of them. moving onto the exciting features , it facilitates archive conversion, file splitting/merging,  byte-to-byte file comparison, discovering duplicate files. other common features  Encryption and Command Line support provided is similar to that of 7zip.


Supported OS: Windows, Linux, BSD.
Download link for Peazip



FreeArc (Freeware)

 

           Third ranker, FreeArc again freeware compressing/archiving tool with PeaZip User Interface. Best part of this tool is according to our testing we found it quite faster than above two. All Features are almost identical to above tools the only point where it stands aside is Encryption provided, it supports AES/Blowfish/Twofish/Serpent . but due other downsides of it like no support for 64bit and lack of support  multi-volume archives , it stands at third position in our list.


Supported OS: Windows, Linux.
Download link for FreeArc



WinRAR(Shareware)

 


         Fourth runner-up WinRAR ,though it is not freeware li ke above three. But due to its Extensive User Interface covering novice/intermediate/advance user makes it stand in our list. It supports RAR and ZIP for packing/unpacking and CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives for unpacking. With support for AES encryption and ability to create self extracting and multi-volume archives. According to its developers it could support archives up to 8,589 billion gigabytes in size sounds interesting.


Supported OS: Windows.
Download link for WinRAR




Universal Extractor(Freeware):

 



 

                 Last in our List , Univeral Extractor . As the name suggest it is only unpacking tool , sounds weird what this tool is doing here if it can only unpack, right ? but wait a sec it can unpack virtually any archives, self extracting EXE sufficient and the only interesting features about it.
   
Supported OS: Windows.
