The quality of a web application depends not only on the content and application functionalities, but also on the the way in which information is presented\nto the user<\/strong> and from the performance that he perceives in using the application itself.

\nStatistics indicate a strong correlation between web application performance and user abandonment rates.
\nIt is therefore important to have, at every stage of the process that leads from creation to Web application management<\/strong>, regarding methodologies and tools\nthat allow for the prediction and measurement of reliability,\nperformance, and the level of service provided, based on\nvarious operating conditions.
\nThe aim of the course is to provide skills<\/strong> and \nmethodology<\/strong> to address the different phases of the design and management process of web applications with a focus on the application's service level, both in terms of performance and information presentation.
\nThe course, starting from elementary queueing theory notions, also addresses aspects connected with the capacity planning of IT systems.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
