Consegna e discussione del progetto
•  Consegna: circa dieci giorni prima della discussione
del progetto
•  Quando consegnare? Durante l’A.A, non ci sono date
predefinite
•  Cosa consegnare? CD con codice, relazione ed
eventuali risultati sperimentali; relazione (no codice)
anche in formato cartaceo
•  Discussione: tutti i componenti del gruppo nella
stessa data
•  Cosa presentare? Una parte del progetto per ciascun
componente del gruppo con ludici (max 10 minuti per
studente)
•  Domande e testing del sistema/servizio durante la
discussione

Common requirements for all projects
•  You can choose the programming language
•  You must use Amazon Web Services (AWS)
•  You can use support libraries and tools to develop
your project (of course they should not overlap with
the project goals!)
–  Be careful: their use must be properly mentioned in the
project report
•  System/service with configurable parameters (no
hard-coded!)
–  Through a configuration file/service
•  You must test all the functionalities of your developed
system/service and present and discuss the testing
results in the project report

Common requirements for all projects (2)
•  System/service supports multiple, autonomous entities
contending for shared resources
•  System/service supports real-time updates to some
form of shared state
•  System/service state should be distributed across
multiple client or server nodes
–  The only allowed centralized service can be one that supports
users logging on, adding or removing clients or servers, and
other housekeeping tasks
•  System/service scalability and elasticity
•  System/service fault tolerance, in particular system/
service continues operation even if one of the
participant nodes crashes (optionally, recovers the
state of a crashed node so that it can resume
operation)

Project 1
•  Mobile Cloud Computing (MCC) application
•  Create a Mobile Cloud Computing application
and exploit the idea of remedying the limited
resource availability on mobile devices
(computing cycles, storage and battery
energy) with the resource abundance in the
Cloud

Project 1
•  Which kind of application? It is your choice!
•  Think of a next generation context-aware
mobile application, e.g.,
–  Context-rich sensing on mobile devices in support
of quality-of-life enhancing applications, such as
photo and video processing to perform face/
activity recognition, speech processing to perform
automatic translation
–  Interactive and delay-sensitive applications, such
as multi-party video conferencing
–  Fast and reliable key-value store service: a mobile
application can store and retrieve application-wide
state information by using key-value pairs

Project 1
•  Propose your service by June 20
–  In 1 page briefly describe your project’s application
–  The number of students in the team depends on
the chosen application
•  Additional requirements:
–  Use at least 2 AWS distinct services
8

Project 2
•  Sensor Cloud service
•  Idea: data streams coming from sensors, IoT
devices, smartphones are processed in the
Cloud
Valeria Cardellini - SDCC 2013/14

Project 2
•  Which kind of service? It is your choice!
•  Some examples:
–  Smart building applications that optimize power
use, air conditioning, lighting, door locking/
unlocking, finding people
–  Mobile crowdsensing applications, e.g.,
applications that fall within the domain of smart
cities, real-time traffic monitoring, crowdsourced
environmental monitoring, ambient assisted living,
or social sensing
–  Possibly saving energy consumption on the data
sources

Project 3
•  Elastic file system in the Cloud
•  Idea: distributed file system that supports
application scale-up and scale-down
–  Applications tag files with different levels of
consistency and persistence (only certain files and
directories are to be kept consistent across VMs)
–  The file system leverages the elastic nature of VM
instances
–  Scale-down can be challenging due to need to
perform state reintegration in case of stateful
services (if a file is divided into chunks, chunks
have to be properly moved/replicated before the
corresponding VM is retired)

Project 4
•  Reinvent Facebook/Twitter in the Cloud
•  In a nutshell: create an eventually consistent
distributed publish-subscribe system with a
social network interface
•  Goal: exploit the use of AWS!
