Cloud computing is a model for ubiquitous and convenient on-demand network access to
a shared pool of configurable computing resources (e.g., networks, servers,
data storage devices, applications and services — together or separately) that
can be rapidly granted and released with minimal operating costs and/or
referrals to the ISP.
The main advantages:
· Does not require large computing power of a PC - in fact any smartphone, tablet, etc, when you open the browser window gets a huge potential;
· fault tolerance;
· a certain level of security;
· high speed data processing;
· the savings on the purchase of software - all software is already in service that will run the application;
· your own hard disk does not gum up - all data is stored on the network.
There are a number of disadvantages:
· Cloud-based service is always provided by a third party, therefore the data security is dependant on this third-party;
· the emergence of cloud-based monopoly;
· the need to always stay online in order to work;
· the danger of hacker attacks on the server (when storing data on your computer you can always disconnect from the mains and clean the system with an antivirus);
· further possible monetisation of the service - it is possible that the third-party chooses to charge users for the services at a later stage.
