Cloud Computing: What is and what is it for?
The last few years have been a revolution in terms of the emergence of new technologies. Concepts such as Big Data, Cloud Computing, are becoming more and more widespread, both in personal and professional use. However, for many people these terms are still the great unknown. In this article we tell you what is and what is the use of Cloud Computing.
The truth is that we use this type of technology in our daily lives in a much more assiduous way than we think. It is possible that if someone asks you for the definition of “Cloud Computing” you do not know very well what to answer, however it is essential to assimilate and understand this concept if you do not want to be left behind in the digital transformation that we are living.
Cloud computing consists of offering computing services over the network using cloud storage. With this type of service, the user does not have to install anything on his computer, however, he will have access to different services (from the most everyday to the technical).
What is Cloud Computing?
To explain this concept as simply as possible, we will use an example: in this case e-mail. More or less all users use e-mail and the truth is that it is a cloud computing service. That is, you use e-mail without having to install anything on your computer, and also for free
The same applies to applications that do not need to download anything. This is because of their cloud storage or their business management systems. This technology is becoming increasingly important in our lives.
Cloud computing is a fast, ondemand and secure alternative for many services.
What is cloud computing for?
One of the greatest uses of this technology is to avoid the computer having to assume a heavy workload when running applications. Cloud storage speeds up the work, making it accessible and without overloading the computer of the user who is using the service.
The only thing the user will need is access to the Internet (as if it were a website). The cloud will take care of the rest of the work, simplifying everything.
Without a doubt, the advantages of cloud storage today are indisputable. Not only are the resources available to the user multiplied, but it also avoids the cost of unit licences, making them accessible to different people on the team.
How Cloud Computing works?
In Cloud Computing systems, we can find two different parts within the system:
- The Frontend (or user interface).
- The backend (i.e. the cloud service itself).
When we talk about the user interface, we will include the computer network, and also the application to access the cloud service. Thanks to an interface the user will be able to connect to the backend through the internet.
When we talk about backend we mean all the systems that the cloud uses for information storage (including servers and computers).
All the different gears, are in charge of connecting to a central server that will manage the operation of the system. This will use key protocols and middleware software to facilitate the connection between the computers that communicate with each other.
This complex (but apparently simple) system brings great benefits to both users and companies.
Types of Cloud Computing
In summary, we could catalogue three types of cloud computing:
- Infrastructure as a Service (IaaS)
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
