Cloud computing

This “cloud computing” democratizes access to an extraordinary source of resources for SMEs, since now an important variety of tools and applications are available from the Internet, which they can use as if it were any service.

ORGANIZATIONAL ADVANTAGES OF USING CLOUD COMPUTING

“The cloud provides service to companies of all sizes… the cloud is for everyone. The cloud is a democracy” Marc Benioff

We can highlight among the important advantages granted by Cloud Computing, the following:

It is no longer necessary to buy an application from a traditional software provider (more expensive than on the Internet); This translates into cost reduction and no payment of software licenses.

It offers multilocation of the service, that is, you do not have to run a software on a single computer or local server, but from any device with an Internet connection we can use Cloud Computing services.

You pay for each service you use at the time you need it, without having to purchase custom software that would eventually become obsolete.

You have the most up-to-date applications on the market, something that until recently only large companies could afford.

It is not necessary that you need in your devices of great storage capacity, but the same cloud provides you with an unlimited amount of space in which you can operate at ease in your work.

You contribute to not increasing the carbon footprint, since the resources that you should have stored in the different devices of the company become virtual, which saves on energy consumption and can reduce pollution by up to 60%.

The cloud provides security to your work in three different ways: a computer failure will not erase your virtual data; If your PC crashes, there is no problem, since you can access your data from any other device; And if you’re forgetful about making backups, don’t worry, since the cloud makes them automatically.

It allows SMEs to be at the same level of business competitiveness as large companies.

CLOUD COMPUTING OPERATION

You have to distinguish Cloud Computing in two parts: the frontend and the backend. For Cloud Computing to work, both parties must be connected through the Network. We will explain each part separately:

Frontend: is where the user’s computer or computer network is located and the program used to access the cloud. If an email is used for this, the program is simply a web browser like Mozilla or Google Chrome. On other occasions, a specific application for access will be required.

Bakend: the place where the computers, data storage systems and servers that form the cloud are located. Each application usually has its own server. To control the entire process of using the cloud by users, there is a central server that monitors both the traffic and the demands of each client. This server follows some protocols (rules) and uses a specific software, the middleware. This software allows computers on the Network to establish communication with each other. Cloud Computing systems, to guarantee data accessibility whenever needed, use twice as many devices as are required to save them and make backup copies of them. In this way, if a computer fails, the copy data can be used.

Cloud types

On the Internet there are several types of clouds, different according to their characteristics and the needs of each company to use. We can differentiate them into:

Public cloud: is that cloud managed by third parties who are not part of the organization. Any client’s data is mixed between the cloud servers. Applications, stored files and more resources can be used by customers through the service provider, owner of all the infrastructure stored in the different devices. Its access by the client is almost always through the same network: Internet.

Private cloud: these clouds are managed for a specific company, a single client that specifies what applications are running and where. They are usually the main option of large companies, which demand more data protection and exclusive services. The company owns the infrastructure, and she decides who has the right to use the cloud.

Hybrid cloud: combines the two types of clouds mentioned above. The client owns part of the cloud and shares the rest. It allows the scalability of public cloud computing resources to regulate workflows, without other third-party data centers being able to access private data from these flows. The part of the public cloud is used for minor tasks, unlike sensitive applications and data, which are saved locally. The hybrid cloud offers the advantages of Cloud Computing (flexibility, scalability and profitability) without the risk of being seen by third parties.

Community cloud: This type of cloud is created by different organizations that are associated for common purposes (for example, security reasons), and is managed by those organizations or third parties.

There are also several operating systems that have or allow cloud computing services, such as Microsoft and Linux.

Types of cloud service

There are three types of models to offer services in the cloud, let’s see them in detail:

SaaS: called in Spanish Software as a Cloud Computing Service, it allows the end user to more easily use the applications through access through a browser or program interface. It is a fairly popular model: approximately, 59% of cloud services are thought to be SaaS until 2018.

PaaS: called in Spanish Platform as a Service, you benefit from the Cloud Computing service while you are free to develop custom software applications. This service is accessed the same as with the SaaS.

IaaS: called Infrastructure as a Service in Spanish, it allows organizations to take advantage of server resources while the rest of the administration of the platform and software belongs to the company.

Have you been clear about what Cloud Computing is and its many advantages? And now that you know, do you also think about taking advantage of the cloud? Comment your opinion and share.
