Cloud computing is a subscription-based service where networked storage space and other computer resources can be obtained. Due to its high availability, easy accessibility, scalability and adaptability, cloud computing is highly desirable in the rapidly growing world of computer technology. Because of this high demand, the Cloud Computing and Distributed Systems (CLOUDS) Laboratory built the CloudSim framework, which became very popular open source cloud simulator among the researchers and students. CloudSim is new simulation framework which allows uninterrupted modeling and simulation of cloud computing infrastructure. It helped open up the possibility of evaluating the hypothesis in a controlled environment where experimental results can be reproduced easily. This basic goal of this paper is helping the researchers to understand CloudSim's most important functions and its practical usage, and to take insights on hands-on example of creating a simulated cloud environment.

“…Recently, the emerged software-defined networking (SDN) and network function virtualisation (NFV) enable DC virtualisation to offer virtualised I/O, virtual desktop, unified communication virtualisation and so on [5], [6]. However, most studies focus on the traditional packet-based DC network architectures [7], [8]. A worth-noting trend is that optical switching technology will play a significant role for future hyperscale data centers [9], [10].…”

Virtual Data Centre (VDC) solutions provide an environment that is able to quickly scale-up and where virtual machines and network resources can be quickly added ondemand through self-service procedures. VDC providers must support multiple simultaneous tenants with isolated networks on the same physical substrate. The provider must make efficient use of their available physical resources whilst providing high bandwidth and low-latency connections to tenants with a variety of VDC configurations. This paper utilises state of the art optical network elements to provide high bandwidth optical interconnections and develop an VDC architecture to slice the network and the compute resources dynamically, to efficiently divide the physical network between tenants. We present a Data Centre Virtualisation architecture with an SDN-controlled all-optical data plane combining Optical Circuit Switching (OCS) and Time Shared Optical Network (TSON). Developed network orchestration dynamically translates and provisions VDCs requests onto the optical physical layer. The experimental results show the provisioned bandwidth can be varied by adjusting the number of time slots allocated in the TDM network. These results lead to recommendations for provisioning TDM connections with different performance characteristics. Moreover, application level optical switch reconfiguration time is also evaluated to fully understand the impact on application performance in VDC provision. The experimental demonstration confirmed the developed VDC approach introduces negligible delay and complexity on the network side.
