Cloud Computing


Have you ever had problems because not enough you storage space on your computer, your USB or removable disk? Or, worse still, has happened that your information has been cleared and had no backups or that these also failed?

There is now a new computer system that can help to avoid this kind of annoying drawbacks and which can be used both by people and companies.

A topic that is broader than was thought, since “it involves not only storage, but it also involves capacity for processing and distribution, all this Internet-based" is cloud.
Cloud Computing ordinary users is probably already a thing of every day. We all use Gmail, Hotmail, or any other email service, isn't it? Then we are already using Cloud Computing somehow; and it is that, little by little, the Navigator, which previously served for that, to surf the Web and little more, is becoming our new operating system, given the amount of applications we give. Have you ever thought in everything what the browser can do? Before, if you wanted to send a message, we had to open a specific program; to chat, another; and to listen to music, we had to open a media player. Today, the browser is able to encompass all of that. To then install programs or applications on our computers if we can get the same services without the need to do so?

What is it?
Cloud computing is the delivery of computing and storage capacity as to service to a heterogeneous community of end-recipients. The name comes from the use of to cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts services with a user's data, software and computation over a network.
There are three types of cloud computing:
·          Infrastructure as a Service (IaaS)
·          Platform as a Service (PaaS),
·          Software as a Service (SaaS).
In this type of computing everything you can offer a computer system is provided as service, so that users can access the services available "in the Internet cloud" without knowledge (or at least without being expert) in the management of the resources used. According to the IEEE Computer Society, is a paradigm in which information is permanently stored in servers on the Internet and is sent to caches temporary client, which includes desktop, leisure centers, laptops, etc.

"This model of technology adapts to the needs of the company at all times, which only pay for what you use"

Characteristics

-Agility                                 - Application programming interface (API)
-Cost                                    - Device and location independent
-Virtualization                      - Multitenancy
-Reliability                            - Scalability and Elasticity
-Performance                      - Security
-Maintenance

Advantages

File:Cloud computing types.svg
  • Proven integration network services
  • Services at world level
  • A 100% infrastructure of cloud computing allows the content provider or services in the cloud without installing any type of hardware, since it is provided by the supplier of the infrastructure or platform in the cloud.
  • Implementation faster and with less risk.
  • Automatic updates that do not negatively affect it resources.
  • It contributes to the efficient use of energy.


Disadvantages

  • Centralization of applications and data storage creates an interdependence of service providers.
  •  Application availability is tied to the availability of Internet access.
  • "Sensitive" data of the business do not reside in facilities of the companies, which could result in a context of high vulnerability to the theft or theft of information.
  • The reliability of the services depends on technological and financial "health" of cloud service providers.
  • The availability of highly specialized services could take months or even years that they are feasible to be deployed in the network.
  • Functional maturity of applications that they are continuously modifying its interfaces, so the companies of non-technological orientation learning curve has a significant pending, as well as automatic consumption by applications.
  • Security.
  • Scalability in the long term.

It was the first time my granddaughter came to me and confided about her battle with oral and genital herpes and her self destructive thoughts.
A gaping vacuum of fear and love opened inside me. I knew what it felt like for her to be in such a situation. But after hearing how someone I loved so dearly struggled I have no option but to promise her help. I wanted to help in all possible ways. I sought counsels from an old and experienced nurse whom I've known to deal on natural herbs because I believed in nature. After hearing from me she smiled and before I could say another word she replied me there's cure but natural herbs. I don't care as long as my child is cured! I shouted. She told me about a doctor in Africa who has cured people of herpes. She gave me his email drutuherbalcure@gmail.com ,I contacted him immediately and then ordered medicine for my child which he sent through the UPS courier to me. My daughter started medication and the next day her mouth sores were physically healing and she told me it's working and within four weeks she testified to me that she was cured! I've always believed that nature has cure for any diseases and I'm happy to tell everyone my child is cured.
Six months later we went for another test to be sure and here is the result,
Six months after medications;
Her hsv1&2 test results;
Igm - 1.49
IgG - 0.36
She don't have any symptoms again and has moved on happily and is now in a serious relationship with her fiancee
