Course Description

Topics

Recently, new technologies have appeared that have definitely changed how internet and the web are used. Cloud computing, service computing and engineering, Hardware as a Service, Infrastructure as a Service, Platform as a Service, Software as a Service, are the basis of what is generally called “Enterprise3.0.” Scalability, reliability, availability and security are the main features that must be provided to users of these architectures. New applications, like Big data and/or data intensive applications introduce also new challenges for the management of the underlying infrastructure and can leverage effectively the adoption of service based and on demand cloud paradigms.

This course will overview a wide set of technologies, providing the rational that governs the design and operation of modern data centres and cloud based systems, introducing also new frameworks for Big data and business intelligence applications (e.g., Hadoop, Spark, Storm, etc.). Moreover, the course will provide an introduction to the fundamental laws for performance evaluation and capacity planning of modern computing infrastructures.

Evaluation

The exam consists in a written test (32 points overall). Students obtaining at least 24 points can work on a project and obtain up to 4 points to improve their grade.  More extended projects can be an alternative to the written test (ask instructors).
