Due to the huge amounts of traffic, telephone network analyzers are complex systems with beefy hardware requirements, complex setup procedures and the need for constant monitoring. For bigger networks the costs to run them is easily worth it, but for smaller networks deploying them might not be feasible. Be it for lack of time to learn how to run them, or because of a too big initial investment.
A recent trend in IT is the introduction of cloud services including for example cloud based service assurance or cloud based VoIP troubleshooting. In this setup the main part of the analyzer system is run in a central system, where it is managed by a knowledgeable and dedicated staff experienced in network monitoring and efficient VoIP troubleshooting. This leads to rapid deployment times and minimal investment to the point where one can just 'Try before you buy' so in other words, troubleshooting on Demand. The advantage of economy of scale brought by cloud based Network Management or cloud based Network Monitoring makes the most advanced analyzers available for even the smallest VoIP providers, leveling the playing field for all. You can even install it at the last minute in just a few seconds and use it when you have a problem
By deploying a VoIP traffic analysis in the cloud, you can usually achieve up-times far better than by using a complicated local setup and you can make sure that your running costs stay predictable. With today's technologies, security and data safety are a well-managed issue, all traffic streams being encrypted. A centralized software setup or hosted service assurance makes updates easier and your service provider is also able to diagnose and fix problems more efficiently by having complete access to the stack.
Cloud-based service assurance or network monitoring or VoIP troubleshooting can now be made available on a pay for use basis. Basically, you pay when you login to troubleshoot a problem on your network. If you do not have a problem, do not ever log in, you do not pay a cent. If you do login, for a small charge for one use, you fix the urgent problem that is troubling your customer. The return on investment for use of the network troubleshooting service is instant. The advantage of having paid the Per-Use fee is obvious to your management, because you have just fixed a difficult problem impacting your voice service. Keeping your customer, your customer and allowing you to move on to creating a new service or engineering your network
Cloud-based network monitoring gives you universal visibility and centralized and universal access to the analysis. One Installation and setup is so rapid it can be used on-demand when needed i.e. VoIP troubleshooting on Demand. In summation, cloud computing brings lots of advantages to VoIP service providers, (ITSP’s) who could not previously afford or justify the expense for a traffic analysis. With generally better availability, a transparent pricing structure (based on usage) and better support options, cloud solutions are surely an understandable trend in today's VoIP software stack market.
