The national Institute of standards and technology (National Institute of Standards
and Technology - NIST) in the document "the NIST Definition of Cloud Computing v
15" [23] defined cloud computing as a model that enables convenient access via the
network to a shared configurable computing resources (e.g., networks, servers, storage,
applications, services). The same document States that the cloud model promotes
availability and is been characterized by the following elements: on-demand self-
service, wide network access, pooled resource, independent location, fast flexibility,
measurable services, scalability, real-world payment;
In the book of John. Riza [15] cloud been defined as something that a user
accesses when they need to use a particular technology, and uses it as long as they need
it, and not a minute longer. To do this, you do not need to install anything on your
computer and do not need to pay for the technology when you do not use it. The "cloud"
is been considered both software and infrastructure. It can be an application that is been
accessed through the web, or it can be a server that you access when you need it.
In educational organizations, cloud-computing tools for educational purposes do
not been used until recently due to the lack of information about them and the lack of
practical skills to use them for educational purposes. And only relatively recently with
the emergence of the concept of modernization of education, where a lot of attention is
paid to the use of cloud technologies in education, future teachers in their professional
activities began to use these technologies, however, not fully.
One of the first cloud services that European educational institutions started using
is e-mail. Ensuring the efficiency of the e - mail service is a simple task, which certainly
does not play a key role in the work of the educational institution. Google and
Microsoft provide educators and students in educational institutions with free email
access.
E-mail allows users (teachers and students) to exchange text and graphic
messages. To implement the e-mail mode, the user's workplace must be equipped with
the appropriate hardware and software: a computer, a modem, a monitor, a keyboard,
a mouse manipulator and software. Traditional basic computer training is not always
enough for the free work of the future teacher in e-mail mode.

It should been noted that the delivery time of a message consists of the time it
takes to send it from the sender's computer to the recipient's computer, and the time
after which the recipient, if necessary, will contact his "mailbox", read or print the
received message. This allows users to work asynchronously, i.e. for each time in the
