1 Università degli Studi di Roma Tor Vergata Dipartimento di Ingegneria Civile e Ingegneria Informatica Progetti Corso di Sistemi Distribuiti e Cloud Computing A.A. 2013/14 Valeria Cardellini Scelta e validità del progetto Comunicare entro 20/6/2014 le seguenti informazioni: componenti del gruppo (nominativi ed ) progetto scelto Numero max di prenotazioni per ogni tipo di progetto Inviare successivamente richiesta per accesso al grant AWS Comunicare e concordare tempestivametne eventuali modifiche relative al gruppo Progetto valido solo per l'a.a. 2013/14 Valeria Cardellini - SDCC 2013/14 1

2 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 Valeria Cardellini - SDCC 2013/14 2 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 Valeria Cardellini - SDCC 2013/14 3

3 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) Valeria Cardellini - SDCC 2013/14 4 Overview of projects Project 1: Mobile Cloud Computing application 2/3 students per team Project 2: Sensor Cloud service - 2/3 students per team Project 3: Elastic file system in the Cloud - 3 students per team Project 4: reinvent Facebook/Twitter in the Cloud - 3 students per team Valeria Cardellini - SDCC 2013/14 5

4 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 Valeria Cardellini - SDCC 2013/14 6 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 Valeria Cardellini - SDCC 2013/14 7

5 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 Valeria Cardellini - SDCC 2013/14 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 9

6 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 Valeria Cardellini - SDCC 2013/14 10 Project 2 Propose your service by June 20 In 1 page briefly describe your project s service The number of students in the team depends on the chosen service Additional requirements: Use at least 2 AWS distinct services Valeria Cardellini - SDCC 2013/14 11

7 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) Valeria Cardellini - SDCC 2013/14 12 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!
