Until a few years ago, business applications list of telegram users in brazil such as ERPs , CRMs, databases or custom applications used by companies were maintained within local networks using a client-server architecture, so that users could use the applications from their workplace. The Internet was used to host the corporate website and to carry out some data or file exchanges.
The emergence of different models of Cloud services, IaaS, PaaS and SaaS, means that the applications used by companies are beginning to cross the barriers of the local network. Much of the software that was previously relatively safe behind the firewall and enjoyed the transmission speeds offered by local networks connected by cable dedicated to the company, is now hosted on external servers and Cloud Computing platforms .

To achieve this, it is essential that the provider offering Cloud Computing platforms for applications 'in the cloud', or that hosts company servers, has a wide communications network made up of various Data centers located in different countries, and is an expert in connectivity services, which allows offering a comprehensive Service Level Agreement for the entire solution, that is, from the user station to access to the Cloud platform where the application is hosted.
In this way, if necessary, the data arrives from the Data Center closest to the client, or if there is an eventual failure of part of the network, the rest absorbs all the traffic and the provider can provide High Availability solutions, which allow connections between all the offices to be ensured at all times, so that the applications continue to function, even in the event of local disasters.
