CLOUD COMPUTING

1.Don’t be confused by the expression “cloud services, you are probably already using them if you use Amazon, Gmail, Hotmail, or Facebook. All it means is that your data is stored virtually.

2.Cloud computing is the delivery of hosted services over the Internet .The origin of the term cloud computing is not known but it may be based on practice of using drawings of clouds to denote networks in diagrams of computing and communications systems.

3.Cloud computing provides easy, scalable access to computing resources and IT services. It can be thought of as similar Cloud Computingto a utility like an electricity grid, delivered over a network .It involves the sharing of resources, services and infrastructure and can often be very cost effective.

4.Amazon played a key role in the development of cloud computing by modernizing their data centers, which were using a fraction of their capacity . The new cloud architecture gave significant efficiency improvements and small, fast-moving teams could add new features faster and more easily. Amazon then developed a product that could provide cloud computing to external customers, and launched Amazon Web Service on a utility computing basis in 2006.

There are three characteristics of cloud services that differentiate them from traditional hosting.

They are sold on demand, typically by the minute or the hour;

They are elastic — a user can have as much or as little of a service as they want at any given time;

services are fully managed by the provider , so the consumer only needs a personal computer and Internet access

To be successful, Companies today need to compete in the global economy and keep up with the pace of innovation. Their IT departments must be agile when responding to changing business needs, and must optimise efficiency and manage costs while enabling their business to stay productive. Cloud computing is one of the key technology trends creating opportunities to address these needs.
Private or Public Cloud.

A public cloud sells services to anyone on the Internet. An example is Amazon Web Services which is thought to be currently the largest public cloud provider.

A private cloud is a privately owned network or a data centre that supplies hosted services to a limited number of clients.

When a service provider uses public cloud resources to create their private cloud, this is known as a virtual private cloud.

A hybrid cloud or hybrid IT is a composition of at least one private cloud and at least one public cloud. Some resources are managed in-house and others are provided externally. For example, an organization might use a public cloud service, such as Amazon Simple Storage Service (Amazon S3) for archived data but continue to maintain in-house storage for customer data that is still active. This hybrid approach takes advantage of the scalability and cost-effectiveness that a public cloud environment offers without exposing critical applications and data to third-party vulnerabilities.


Cloud services are broadly divided into three categories:

Infrastructure-as-a-Service (IaaS),

Platform-as-a-Service (PaaS)

Software-as-a-Service (SaaS).

Infrastructure-as-a-Service allows users to start, stop, and access and configure their virtual servers and storage. An example is Amazon Web Services. A user will pay for only the capacity that is needed, and can bring more online when required. Because this pay-for-what-you-use model resembles the way electricity, fuel and water are consumed, it’s sometimes referred to as utility computing.

Platform-as-a-service is a set of software and product development tools hosted on the provider’s infrastructure. An example is GoogleApps. Developers create applications on the provider’s platform.

HIDE YOUR FILES IN YOUR COMPUTER, YOU DO NOT NEED ANY SOFTWARE.

How can you hide your files and folders not to be seen by anyone other you? Its just a simple trick anyone can do, what you need is just a basic understanding of how to use a computer.
Do the following:

  • Click on a start button: In a search files and programs type the word RUN (doesn't matter whether you use capital letter or small letters)
  • Click on RUN and type the word CMD and a command prompt box will open. There you are and now you can hide your files, by:
This is how a command prompt looks like

  • Type the following line of command attrib +s +h D:\pictures (Depends on the file you want to hide, mine was pictures)
  • After you finish typing that press enter button in your keyboard, then go where your file was located and you will no longer find it.
  • What is that? The letter D is the drive where your file is located and pictures is the file name I want to hide which is located in D drive. So if the folder you want to hide is called music and is in drive E the command line will be attrib +s +h E:\music
  • So what if the folder called music is located within another folder called songs? Its easy you just type this                              attrib +s +h D:\songs\music and press enter button to hide your folder.

That was hidding a folder, now is how you can Unhide it.
  • It is just changing the + sign and put a - sign, for example in our first trial we hide the folder named pictures which is in D drive, this is how you can bring it back, 
  • Use the first and second step above to get to a command prompt
  • Type attrib +s +h D:\pictures
  • Press enter in your keyboard and get back to your drive to check your folder

NB:
  1. To unhide you just put a -(minus) sign before s and h while to hide you use +(plus) sign
  2. There are spaces between attrib and +s
  3. The drive letter does not start with a + sign
