Cloud environments provide elastic capacity and flexible pay-as-you-go business model, and can significantly reduce the operational cost for resource-intensive applications like big data, deep learning and the Internet of Things (IoT). The virtual infrastructure, including networked virtual machines, for large scale applications, is often distributed, and involve resources not only from data centers, but also distributed Fog and Edge nodes. It is not always feasible to use resources all from a single provider. The provisioning of a complex virtual infrastructure requires dynamic partitioning of the topology and seamless configuration of the network, to meet the latency constraints of geolocation devices, to optimize the price and Service Level Agreements of the application. In many cases, the partition solution of a virtual infrastructure cannot be done in the design phase and has to consider the actual resource availability of providers at the provisioning stage. This paper presents a virtual infrastructure partitioning and provisioning solution with consideration of the QoS and resource constraints from the application.

“…Unlike traditional physical infrastructure, the virtual infrastructures provide developers with flexibility for planning not only capacity and type of the VM, but also their locations, i.e., the chosen clouds and data centers used [9]. Moreover, provided network resources can also be customized [10], [11].…”

“…However, these tools need infrastructure resources provisioned in advance, which does not have controllability on the underlying infrastructure at runtime. Koulouzis et al leveraged the programmability of the network to optimize the data transfer, but the control on the switch of the data center is required, which is not practical for cloud computing from the customer perspective.…”

The infrastructure-as-a-service (IaaS) model of cloud computing provides virtual infrastructure functions (VIFs), which allow application developers to flexibly provision suitable virtual machines' (VM) types and locations, and even configure the network connection for each VM. Because of the pay-as-you-go business model, IaaS provides an elastic way to operate applications on demand. However, in current cloud applications DevOps (software development and operations) lifecycle, the VM provisioning steps mainly rely on manually leveraging these VIFs. Moreover, these functions cannot be programmatically embedded into the application logic to control the infrastructure at runtime. Especially, the vendor lock-in issue, which different clouds provide different VIFs, also enlarges this gap between the cloud infrastructure management and application operation. To mitigate this gap, we designed and implemented a framework, CloudsStorm, which enables developers to easily leverage VIFs of different clouds and program them into their cloud applications. To be specific, CloudsStorm empowers applications with infrastructure programmability at design-level, infrastructure-level, and application-level. CloudsStorm also provides two infrastructure controlling modes, ie, active and passive mode, for applications at runtime. Besides, case studies about operating task-based and big data applications on clouds show that the monetary cost is significantly reduced through the seamless and on-demand infrastructure management provided by CloudsStorm. Finally, the scaling and recovery operation evaluations of CloudsStorm are performed to show its controlling performance. Compared with other tools, ie, "jcloud" and "cloudinit.d", the scaling and provisioning performance evaluations demonstrate that CloudsStorm can achieve at least 10% efficiency improvement in our experiment settings.

In comparison, there are also some environment-centric 1 tools to help developers orchestrate their applications, which include Puppet, # Chef, ‖ etc. These tools more focus on the cluster management, ie, deployment and configuration, instead of provisioning and scaling automation. Some academic research studies also propose architectures for developing and orchestrating applications on clouds, eg, CometCloud 6 and mOSAIC. 7 However, most of these architectures themselves are platforms, which require manually to set up the cluster in advance and lack the ability of provisioning VM resources.

“…The logically centralized controller of SDN can control and view all the forwarding packets between network devices using OpenFlow interface [6]. This is why SDNs are highly flexible compared to traditional networks, where in the latter the administrators need to make custom policies and protocols on each network device [8]. Furthermore, OpenFlow architecture supports security since the OpenFlow channel can encrypt traffic by using Transport Layer Security (TLS) [7].…”

The number of students who obtained degrees via distance learning has grown considerably in the last few years. Services provided by distance learning systems are expected to be delivered in a fast and reliable way. However, as the number of users increases, so does the stress on the network. Software-Defined Networking, on the other hand, is a new technology that provides a rapid response to the ever-evolving requirements of today's businesses. The technology is expected to enhance the overall performance of cloud services, including those provided by distance learning. This paper investigates the benefits of employing such a technology by educational institutions to provide quality services to the users. The results of the experiments show an improvement in performance of up to 11%, when utilizing the technology. In addition, we show how resource reservation features can be utilized to provide quality service to users depending on their role in the distance learning system.
