The IP Multimedia Subsystem (IMS) is a key component in the Mobile Next Generation Network, which is used by telecommunications operators throughout the world to provide access to multimedia and broadband services. As these services become more sophisticated, and as the number of clients rises drastically, it is increasingly expensive to install and operate a network that will satisfy the users' expectations. Cloud computing combined with high-speed networks provides a potential method for reducing the installation and operational costs of IMS. However, their use may introduce performance degradation in certain parameters, such as the delay. We will construct a test environment that will permit us to model a cloud-based IMS system, after determining which components of IMS could benefit from this approach. Successful adaptation of IMS to the cloud-based environment will permit telecommunications operators to improve the availability of their Application Servers, which will enhance the user experience.
