The new computational modalities have allowed a radical change in the way of doing computing. We will discover the fundamentals and characteristics that make possible the operation of innumerable digital services in the cloud.
The foundations of the world of computing and computing have not changed radically. The elements and principles that make calculations, programs, and computation, in general, have not changed significantly, but have become more powerful and effective. Even so, the disruptions and new models created that are giving way to the rise of cloud computing are simply based on a reorganization of these elements and a new business model to trade these services.
To go into greater detail, we will say that the change that makes this new world possible is based on moving these services from the local to the remote, driven by the advance in communications and the great speed of the internet that can be enjoyed today. In this way, you can trade services that mutually benefit the provider and the customer, even giving rise to new services previously unimaginable.
Many benefits appear when reorganizing computing on remote devices:
The technical responsibility of maintaining the proper functioning of the computer equipment is the owner of these. The data centers are those that have clusters of servers where the computation is made, and, therefore, they must be responsible for the proper functioning and maintenance tasks.
We no longer have to acquire all the necessary equipment to run computing solutions, whatever they may be because we only need the devices where the interface and the data results will be displayed. This translates directly into lower equipment costs because it does not require large computing power.
In addition to the above situations, it was necessary to have qualified personnel to manage all these components and provide technical support in case of errors and failures. Now it is unnecessary, because the responsibility of the support is the owner of the equipment, so the costs decrease drastically due to these 3 factors.
The radical difference is in the billing model, while in the traditional model equipment and software licenses were purchased, now it is simply paid for use in units of time or computation, but in any case, they make these resources more accessible.
Some of these services in the cloud are:
1: The software:
This indispensable element of commercialization has remained invariant for a long time because the commercial model was always the same: develop a computer solution and sell licenses for local use. Thus, users installed the program or application on their devices and paid only once to be able to use them for life.
It seems somewhat profitable to be perpetual, but the problem appeared when the developer launched a new version with desired improvements, accompanied by the cession of technical support and compatibility of the previous version, so that it is retiring to the software already acquired, which it pushed us to pay for the latest version entering an infinite cycle.
But with the paradigm of Software as a Service ( SaaS for its acronym in English) always available the latest version, since the developer implements these updates without users having to take any action, so we will never have an obsolete software. The obvious disadvantage is that the user of the system no longer has the freedom to choose the version he wants, but must always stick to the last one.
2: Hardware and infrastructure:
While to carry out a particular task requires specific hardware, which we previously had to acquire and implement on our own. Nowadays, we can access virtualized hardware paying only for use ( IaaS ).
In this category, we find many services that allow us to simplify processes and computing tasks such as:
Hosting or web hosting:
If you want to know how to make a blog or another type of web, you should consider this service. It is required of him to provide a website of any magnitude, in such a way that we should not take care of the infrastructure, but pay for the use.
Certain corporate tasks require some infrastructure to develop them. In this way, you can create virtual local networks or private cloud to maintain complete control over resources without having to have the necessary equipment and devices.
To store large volumes of data requires computer equipment with disks that give us the ability to store our information and thus be able to process it. Although a mass storage device is not a great cost to face, there are enormous advantages in the computational model of the cloud (STaaS):
Easy to share:
When we want to send a file to another person, we must take charge of transferring it, and depending on the volume of information it can take a considerable time, even more, if the internet connection is asymmetric. But this is not the case in the cloud since you simply share a link where the file is already available online.
Better accessibility to information:
It is not necessary to configure remote access to your computer since the files are available 24/7 on the internet, which is protected by a password so that only you and the authorized persons can access it.
The possibility of collaboration in teams:
The group dynamic of document editing changes forever. It is no longer necessary to send versions and revisions of the same file by email to all team members. Now the files reside in a remote location and in combination with the SaaS, which benefits you with software in the cloud of editing and processing of text, your team can work on the same document in real time and always updated.
In this way, and simply reordering the processes and ways of managing the data, you can obtain an excellent business model, where the rules are not all given so you can innovate and get everything you need to run your business project.
