An article at PC World discusses the pros and cons of cloud based streaming. There is a growing collection of suppliers in the consumer and business market for music streaming services however in my experience streaming services haste weaker and thus secondary to satellite and downloaded music simply because the Internet isn’t the perfect technology for delivering a consistent stream of audio. For starters the quality of the audio will be lower than other methods to deal with the challenges of an inconsistent technology but even with this, Internet streaming services are challenged with variable demands on central servers and metropolitan and local networks that can at busy times of the day become congested. Te Internet is build on a type of network that encapsulates the data and sends it to its destination much like a postal service. The way it does this harks back to the original design of the internet which was based on having to deal with war situations. Because of this the network cuts up any data to be sent and packets the chunks up to send across to the destination in any way it can get there, which could be various.
So ultimately, streaming audio and video are the lost challenging types of data to provide a business class service with.
This is why satellite services still provide a quality that Internet radio or streaming can not albeit at a higher price. However downloaded music overcomes the cost of satellite services and the quality that streaming pushes down.
So when considering a service for music for your business see if you can get trials first and make a decision in real business day use.
