Sharing, transmitting, and storing data has been one of the great needs of today. In the last years, concepts and developed methodologies of cloud computing systems have been improved. This concept created in the 1960s today is present in daily life from ordinary users to even large companies. The present study aims to develop a method of data transmission based on discrete event concepts. This methodology was named CBEDE (by the acronym). The experiments were matched in the MATLAB software simulation environment, where the memory consumption of the proposed methodology was evaluated. Therefore, the CBEDE methodology presents great potential to intermediate users and computer systems, ensuring speed, low memory consumption, and reliability. Being the differential of this research, the use of discrete events applied in the physical layer of a transmission medium, the bit itself, being this to low-level of abstraction, the results show better computational performance related to memory utilization related to the compression of the information, showing an improvement reaching up to 69.93%

The roots of the Internet are in the 1960s, but their relevance to business was only first noticed in the early 1990s. The World Wide Web was born in 1991, and in 1993 a browser called Mosaic was released, allowing users to view text pages with graphics. This fostered the creation of the first corporate websites and, not surprisingly, most of them were from computer and technology companies. As Internet connections became faster and more reliable, a new type of enterprise, called the Application Service Provider (ASP), began to emerge. ASPs managed existing business applications for their customers. These companies acquired computing power and administered the applications to their customers who then paid a monthly fee to access the applications over the Internet (Comer, 2018). But it was not until the late 1990s that cloud computing as we know it today began to emerge. Cloud computing is the on-demand delivery of computing power, database storage, applications, and other IT resources through an Internet-based cloud service platform with a price-by-use setting (Jain, Deshpande, Raghu, & Khanaa, 2017).

In 1997, during an academic lecture given by Ramnath Chellap came to the term Cloud Computing. However, many consider this concept to be associated with John Mccarthy, he is considered the pioneer in Artificial Intelligence technology and also the creator of the LISP programming language. This association of the term cloud computing to Mccarthy is due to the fact that in 1960 he stated that “computing may someday be considered as a public utility.” In addition, since that time he had been discussing the term time-shared computing sharing. For him could computing allow a computer to be used simultaneously by two or more users in order to perform tasks, taking advantage of the amount of time available between each process. In this way, using the computer together could generate better use and decrease of expenses, since the user would pay only for the time of use of the equipment or, in this case, the technology of the Cloud (Jain, Deshpande, Raghu, & Khanaa, 2017; Rittinghouse & Ransome,2016).

At that time along with Mccarthy, the physicist and scientist of ARPA (Advanced Research Projects Agency) Joseph Carl Licklider, was also creating another concept that would revolutionize the world. Licklider was looking for other useful utilities for the computer and ended up discovering a powerful way to connect people, allowing the communication and sharing of data on a global scale. He is currently considered the pioneer in creating the Internet in the form we know today. From this, it was possible to create a global network of sharing and communication, the ARPANET that evolved to the Internet and enabled the Cloud Computing to begin to take shape. The origin of its name, the cloud, comes from the diagrams of the old ISDN (Digital Services Network) and Frame Relay data networks designed by telephony operators. The interconnection between the two was shown by cloud drawings, to signal something that was out of the reach of the companies. Therefore, we do not always know which computers are the applications in Cloud Computing (Jain, Deshpande, Raghu, & Khanaa, 2017; Rittinghouse & Ransome,2016).

Nowadays, more than 50 years after John Mccarthy's phrase about computing as a public utility, Cloud Computing technology already has a strong breadth. This technology began to be offered commercially in 2008, when small, medium and large companies gradually adopted the technology. In the year 2013 already had an immense acceptance by the corporate universe. This great acceptance has been transforming the service, so that the processing and storage of data began to be treated in the same way as a service of electricity supply, where it is only paid for consumption (de Bruin & Floridi, 2017; Chang, 2015).
