Cloud is shared… experience, Infrastructure, resources (CPU, memory, network).
Due to the very high complexity and cost of such infrastructures it is easier to lease such platforms/ instances from a provider, vendor. This centralized massive infrastructure enables the deployment of massive centralized applications to be created, and to be accessed/ shared from a massive audience simultaneously from Everywhere there is Internet connection.
Which changes the game of a traditional enterprise environment…
The result… lowering the end user cost for accessing these applications
at a better quality, speed, security (Video streaming and Netflix is one good example of cloud utilization).
