A study and evaluation of the management complexity of Cloud infrastructures

In this paper, we describe the experience obtained during undergraduate dissertation. We work on cloud infrastructure and particularly in Eucalyptus cloud [1]. We configured and managed a cloud system which fulfills availability, scalability and reliability criteria.

Cloud computing has created a revolution in IT industry, combining the model of virtualized resources with the model of offering platforms (middleware) or an application as a service over the Internet. There are several solutions to group computers in a network, like Amazon Web Services (AWS) and OpenNebula.

In early 2008, Eucalyptus became the first open-source, AWS API-compatible platform for deploying clouds. Eucalyptus 2.0 is an Linux-based software architecture that implements scalable, efficiency-enhancing private and hybrid clouds within an organization's IT infrastructure. Eucalyptus provides Infrastructure as a Service (IaaS).

Eucalyptus does not support a tool for monitoring events that take place in the center such as crashing of a Virtual Machine (VM). For this purpose we deploy OpenPegasus [3]. OpenPegasus is an open-source implementation of the DMTF CIM and WBEM standards. It is designed to be portable and highly modular. It is coded in C++ so OpenPegasus effectively translates the object concepts of the CIM objects into a programming model but still retains the speed and efficiency of a compiled language.

The paper structure as follows: In section 2, we describe how we deploy Eucalyptus, alternative implementations and the problems we face. In section 3, we focus on monitoring the cloud and give solutions in unexpected events that take place. In section 4, we provide some measurement regarding the speed of the cloud. Finally, in section 5 we conclude
