Cloud computing: Advantages and disadvantages is a new model of digital services, which offers the possibility of accessing unlimited computing resources, such as: networks, servers, virtual machines, storage and applications, through the use of the Internet.

The first known service of this type is e-mail, which allows private messages to be exchanged with other Internet users, from anywhere in the world. In addition, it is the most popular and traditional digital communication medium in history.

The use of cloud computing, as it happened with email, has been expanding throughout the world, where more and more users are joining this technology. Various sectors of society have adapted this tool to their way of working, such is the case of the economic, educational, government, financial and business sectors, among many other important areas that contribute to the progress of countries.

Similarly, many people, from an individual point of view, use these tools for recreational and recreational purposes.

Although it is true that at first there was some reluctance to use this digital medium, mainly due to the fear that personal information would be exposed to thousands of cloud users. The truth is that, today, the number of people who hire cloud services continues to grow exponentially.

Cloud computing: Advantages and disadvantages shows that it has three service modalities and four implementation models, the possible combinations of which provide the user with a wide range of opportunities when choosing the service of their choice.

Service models range from software to infrastructure to platform. While the implementation of services is aimed at both the public user and the private, community or hybrid.

SaaS model

It refers to software as a service, that is, the provider provides the application already developed and executed in the cloud. The user accesses it through an interface with an internet connection, without knowing the infrastructure that made the enjoyment of the service possible.

PaaS model

It’s about platform as a service. The service provider provides the user with the tools and programming languages ​​necessary for the user to develop their own applications in the cloud.

IaaS model

It constitutes infrastructure as a service. The consumer can process and store computing resources in the cloud, resulting from the execution of the software of their choice.

Public cloud

It implies access to the cloud by the general public, as long as it is connected to the internet.

Private cloud

The service is directed only to the contracting user of the same.

Community cloud

The service complies with characteristics defined by groups with equal interests.

Hybrid cloud

In the hybrid cloud, the service is shared by several proprietary users who benefit from the advantages of the others.

Service Providers

Today, more and more companies provide cloud computing services worldwide. Among the main ones we find: Salesforce, Dropbox, Zoho, Google App Engine, Windows Azure, Amazon Web Services, Right Scale, etc. Each and every one of them oriented towards specific service models, and experts in implementation modalities according to the type of user to whom they are directed.

Collectively, cloud computing service providers: Advantages and Disadvantages have resulted in a diverse group of digital applications that many of us use on a daily basis, in every aspect of our lives. Such is the case of the Google Calendar agenda and calendar, the Doodle activity planner, the Padlet multimedia tool, the Zoho word processor, the free storage site Google Drive, the Spotify music application, the Teamviewer business tool, among many others. useful and innovative applications.

Advantage advantages and disadvantages of cloud computing

Cloud computing: Advantages and disadvantages has multiple attributes, among the main ones are:
• The user only cancels based on the use of the service and the time consumed. In other words, you do not overpay for a service you did not enjoy, which ultimately translates into time and money savings.
• It does not require the use of the client’s computing resources, since the client performs the work using the remote machines of the service provider. Therefore, the wear and tear of your own equipment decreases.
• It lowers the costs arising from the possible purchase of new computer equipment and the payment of the corresponding licenses for each of the required software.
• Similarly, it reduces costs for electricity consumption, due to the decrease in computer equipment in use.
• It does not require the use of large spaces to function, and it is not necessary for the customer to know the physical location of the service provider.
• Allows each user to log into a web platform that contains all the applications they may need, instead of requiring the installation of software on each of the computers. Access is made through the use of usernames and personalized keys.
• The contracting of the service can be easily modified, depending on the appearance of new user needs, without this representing a breach of the initial conditions.
• The user can access the services from anywhere in the world and at any time of the day, as long as they have an internet connection.
• The technology is compatible with any device that has an internet platform, for example: cell phones, tablets, laptops, etc.
• It stimulates the creation and use of new technologies, as well as the growth of companies, since anyone who wants to offer cloud services has the freedom to start and stay.
• The service seeks to benefit the client, at the same time as providing economic benefits for the provider.
• In the event of loss of information, its recovery is quick and easy thanks to the storage service available in the cloud.

Disadvantages advantages and disadvantages of cloud computing

Fortunately, cloud computing has more advantages than disadvantages. However, it is fair to make them known.
• Creates dependency on the service provider, due to the ease of use that most of them offer, as well as their centralization.
• There may be information loss due to the considerable volume of information to be shared through the cloud.
• There is a certain level of vulnerability of sensitive data, which could expose the client to serious computer attacks, such as identity theft and information theft.
• The enjoyment of the service depends, to a great extent, on the operation of the internet network. When this fails, consequently, the contracted service can be interrupted.
• Free computing services that store data in the cloud do not offer users as many security and privacy options as they would like.
• It is necessary to strengthen the existing legislation regarding data protection, privacy and responsibility for the violation of content and licenses.
To get an idea of ​​what the downsides of cloud computing truly represent, let’s take a real-life example.

Example advantages and  disadvantages of cloud computing

Let us suppose the case of a company dedicated to the manufacture and sale of medical supplies, which decided to store all its information in the cloud to access it automatically from any device when required. What will happen if when you need to carry out the monthly inventory of your merchandise the internet platform does not work? How can you proceed with the inventory replenishment if you do not know the behavior of the sales? Will you be able to meet the needs of your customers if you do not have access to their requirements?

Undoubtedly, these and many other questions will constitute real problems when making decisions related to the operation of the organization.

While it is true that cloud computing service providers usually have several servers scattered around the world, it is also true that these can fail simultaneously, preventing the provider from giving instant help and technical support to the company. of medical supplies, and any other that is in the same situation.

As we’ve already mentioned, the risks are less than the payoffs of cloud computing. So, based on this same example, we can also say that, under normal operating conditions of the services, the members of the organization will be able to consult the information of their clients and suppliers without schedule limitations.

It will be possible for them to continue with a half job from the comfort of their home, and the lack of synchronization of the information modified by various team members will no longer be a problem, among many other qualities in favor of computer services in the cloud.

In figures advantages and disadvantages of cloud computing

It is expected that in 2020 the economic benefit generated by cloud computing will exceed 270 billion dollars worldwide. 70% of people use services and applications from the cloud, as part of their daily activities. By 2020 there will be more than 30 billion devices connected to the internet, enjoying the diverse range of digital services available in the cloud.

60% of companies hiring cloud computing services see positive results in the medium term. Also during 2020, the cloud will store 35 zettabytes of data worldwide.
43% of public companies lack the information and communication technology skills required to face the digital solutions offered by cloud computing.

The use of digital services reduces between 30% and 90% the use of electrical energy in the contracting organizations.
60% of cloud service revenue comes from North America. Cloud computing will continue to expand its services to all corners of the world.

recommendations advantages and disadvantages of cloud computing

Cloud Computing: Advantages and Disadvantages shows among the recommendations that because it is a contracted service, it is important and necessary that the user carefully read the conditions of use before accepting them. Avoid being reckless when storing and sharing data through the cloud. Use strong passwords, with more than six digits or combined characters.

Keep usernames and passwords in safe places. Frequently change the passwords associated with the contracted services. Do not share them with other people. Optimize privacy and visibility options that depend directly on the user.
