cloud computing is a server or several servers that allow us to connect through the Internet to offer different services or offer services to us. This is widely used today, by many companies and people, every time more are adopting it.
There are many pages or websites that use the computing cloud, but perhaps due to a lack of knowledge on this subject we don’t even know how to recognize thembut for this and other things, we put together this post.
Today, we will show you a clear and simple concept about the computing cloud, where we will explain what it is, its characteristics and other things that will allow you to clearly understand this world. Here you will find why it would be useful or not to use it, and you will give that criticism after reading what we leave below.
What is cloud computing and what are its characteristics?
Computing in the cloud is one of the provision of computer serviceswhich offers us the opportunity to organize and distribute resources in the most flexible way and with economic scales.
Part of the services that it offers us are: good storage, , , and intelligent analysis, all through an Internet network that connects to a server known as the cloud.
You need several servers with Internet connection, which is responsible for meeting all the needs that the client or user may have, one of the most common is access to information and its manipulation.
Although now used mostly for mobile devices, is a service that we can access from any device, be it mobile or fixed, located anywhere. Although the amount of services you offer or not depends on the provider or of the type of user that we have paid or obtained.
But what is cloud computing and how does it work?
In itself the computing cloud, allows us to store documents and filesand it works through a useful system that allows the sharing and transfer of packages.
It is divided into two parts: Front end and Back end, whose objective is to make the system work correctly through the Internet connection:
- the front end, is the one we have on our computer or in some cases on the end user’s computer network, which gives us access to the cloud. This is very common in the case of emails, that works like a web browsersomething like Google Chrome, although this is not always the case, since it needs an App that serves as a complement to its function, which is to give access.
- the back endis directly dedicated to servers and data storage systems, although Apps generally have their own server, which is responsible for controlling the sending and receiving of packages so that everything works correctly.
This server is guided by a series or list of protocols and software known as middleware, allowing computers to communicate with each other.
Being fundamental characteristic in some cases the backup copies, so that when the files are lost we can always access a recovery of them.
Types of clouds, how are they classified?
Cloud computing services can be classified into three, each with different functions and characteristics, such we explain it to you below:
- Private: This is the cloud, which offers us computer services through the Internet, but on a private network, widely used by users who limit the public from viewing their content. This is known as a cloud with corporate services, or also an internal cloud.
- Public: This is a service offered through a public network, therefore the server is mostly provided by external providers through the Internet, and we can find it available worldwide.
- Hybrid: Well, as the name says, it is composed with public and private characteristics, which allows a dynamic between the clouds, all depending on our needs and the costs that arise. In case this is one of the cloud services most used in the worldand all because of its high flexibility in acquiring an external space.
What types of services can be offered in the cloud?
cloud computing can offer us different types of servicesFor this reason they are so important to many people. Next we will show you:
Software as a Service (SaaS)
It is a hosting service on provider servers, where we as customers we can access them through any browser, some provider offers support and availability services. This group includes the best known such as Google Apps and others.
Platform as a Service (PaaS)
It is a type of service that a provider offers us, through remote access. One of the most used is iCloud, where we (users) we can create an account and manage our resources our way, all that infrastructure is provided to us by the provider.
Infrastructure as a Service (IaaS)
This is a service provider that provides a series of software and Internet Apps. Whose cycle is subscribe, access through the web or the APIs of the same provider.
*Note: A common user naturally uses only SAAS.
What uses can be put to cloud computing?
If we are using the cloud computing service, to protect our documents, It is necessary that you know that even if you do not program it or do it manually, it does it automatically after purchasing it.
But this is not the only use that can be given to it, there are others such as the ones that we will show you below:
Build cloud-native apps
This is the main use that advanced people in the matter they give these services, whose focus is to offer technological, mobile and API Apps. These work as containers for a large number of computer packages where at one point they allow access and downloading of them.
Test and build apps
Creating an App takes a lot of time and in some cases even a great cost, but by developing them through a cloud service, time and cost can be greatly reduced.
Store data, create backup copies of it and recover it
When we talk about data protection, we refer to the same thing that we mentioned at the beginning of this section, and that when we use a cloud service our data is exposed to a lower risk of loss, so we will always know where we can recover it in the event of a loss.
analyze data
This is one of the great uses that we can give it to cloud servicesand it is because we can unify our data between different teams, and use the benefits of the cloud such as learning or artificial intelligence, and thus be able to compare the information and make more informed decisions.
Stream audio and video
Streaming is the direct connection between two points, which allows us to connect with our audience at any time and from any device and place. By using cloud services, users can view content whenever they want, as long as we give them permission.
incorporate intelligence
intelligence models we can use them to attract more customers and offer more detailed support or information that allows us to strengthen our relationship with them.
Deliver software on demand
This is in a use that is mostly given through the use of the SaaS service, which allows us to offer our public the latest versions or software, when they want and need it.
What are the main advantages and disadvantages of cloud computing?
Cloud computing offers a number of services which gives us a variety of advantages, and since nothing is perfect we can also find some disadvantages. These are the following:
Advantage
Here we will show you one List of the most common advantages that we can find when using the computing cloud:
- Simple and fast access: We can move our data from any computer no matter where we are, the only thing that is necessary is to maintain an Internet connection, during the process or use.
- easy use: Normally cloud services are complete and very easy to use, since their structure is focused for all types of users, even those who are not advanced.
- Complete security: This is such a secure system that many of us prefer to save our documents or back them up with a service like this, so much so that many companies use it.
- Great privacy: By creating a user and uploading our files or documents with that profile, we will know that only we will see and manage the information contained and supplied by ourselves. There are more closed systems that have greater security in order to avoid cyber risks.
- Very economical: The services offered by cloud computing providers are quite cheap, not to mention the rent or profile that we have on the platform, but we avoid fixed costs such as electricity consumption and others.
Disadvantages
As we already said, Not everything is rosy so we can find different advantages, although the most common are the following:
- Poor security on some servers: We know that we mentioned security well in the advantages, but we cannot ignore the great possibility that there is a cyber robbery, which is very common today.
- Slow connections: If there is a considerable number of people connected to the server, it may affect the speed of data transmission, a situation that many of us are going to hate when it happens to us.
- Services with limits: All providers offer us different plans or profiles that vary in features and limitations, so to access a better service we will have to pay more, so if our plan is medium we will not be able to access the full version.
- Continuous Internet connection: It is extremely necessary that we maintain a constant connection to the Internet because in this way it is possible to link the two points allowing the sending and receiving of documents and files.
