SCIENTIFIC VOCABULARY
The term "cloud computing" is in style nowadays
but it is not a new concept.
When we talk about "cloud" we are referring to the Internet.
What changes is the way in which we work with servers.
Previously, a server was a physical machine
with its hard disk drive, memory and processing capacity.
Now, servers are virtual. This means, that we can have
only one physical part as virtual server
or have a large virtual server formed by physical servers.
This offers companies the ease of extending
or decreasing the ability of calculation or storage instantly,
without having to install servers or to disconnect existing servers.
This implies a reduction in time and realisation costs.
In relation to this concept, we spoke about cloud storage.
There are virtual devices in the cloud as Dropbox,
and storage services as Mega.
And what these services offer us is the possibility of having
all our information, music, videos and documents on the Internet
to be able to access them from anywhere and any device.
It is comfortable and with advantages, but it has a disadvantage
because we are condemned to be connected to the Internet
permanently and connection costs are high
so it is not a clear choice for the future.
