During the installation of the REMWAVE ITSP solution the installer displays an info box, recommending the user to contact REMWAVE if the test environment will be tested with more than 5,000 users. I received the question of why we would ask the user to contact REMWAVE?

The REMWAVE evaluation solution we offer for download is somewhat optimized to be installed on a single Windows 2003 server. All components are configured in a way to use the least amount of resources as possible. The SIP proxy starts in a special mode and the Oracle Express DB uses a small footprint and so on. This setup should be fine for a couple thousand registered users. The moment you want to scale it is when REMWAVE outshines the competition. It scales horizontally and vertically perfectly. For those of you who "like to play it safe" there is no single point of failure, addionally,  there is room for almost infinitive scalability. Unlike other solutions available we offer true load balancing of our core components. SIP sessions can be spread equally over a large battery of SIP proxies and fill entire racks with nothing but SIP signaling (yes, also UDP) and PSTN gateways can be load balanced as well. This is unlike other solutions which confuse load balancing with fail over configurations which is way easier to realize. REMWAVE does scale! The first step for larger installations will be to change parameters and the second step will be installation on multiple systems. In some cases we might also consider setting up multiple machines in virtual containers which will be later moved to different servers. Many scenarios are possible. As a matter of fact – even during your system evaluation you will be covered, just ask us and we can show you how you can scale REMWAVEs solutions to meet true enterprise needs.
