Abstract

Cloud computing is one of the most challenging concepts on IT industry. These systems provide a big variety of applications on every level. This thesis describes the functionality, tools and architecture of okeanos cloud computing service. Okeanos platform is an Iaas cloud computing system by Grnet that aims to provide a cloud based fully virtualized solution for academic and research community. Α basic set of compute and network resources used, in order to develop a fully functional VOIP system. The related system used Asterisk opensource software project to manipulate and coordinate communications between clients. Then an automated monitoring procedure starts a python program. This happens, when networks interface traffic exceeds a minimum threshold. The above Program, communicates with okeanos platform through restful APIs, and creates a new cluster of servers with more compute and network resources. Also, a multi-tier network connectivity schema handles the connection not only between client and servers but also manipulates a trunk connectivity between servers. During the implementation of the above system a smart configuration was designed for the Asterisk servers just to make the transformation easier and with better efficiency.
