The benefits of virtualization across the software development pipeline

Abstract. The emergence of cloud computing and the evolution into service-based solutions across the software industry have influenced many changes in software development paradigms and methods. As a result, various forms of virtualization and container-based solutions have become more and more commonplace throughout the field, with technologies and frameworks such as Docker and Kubernetes becoming industry standard solutions to virtualization. This thesis is a literature review into existing research on virtualization and containers, and their use in various categories of the software industry. The aim of the thesis is to look at the reasons for the proliferation of virtual machines and containers, along with their benefits for the software development process, the continuous integration and delivery pipeline, and the different cloud platforms and providers. The benefits of virtualization are clearest in the cloud infrastructure, as cloud services are inherently built to utilize virtual machines. Containers and container orchestration systems allow container management and dynamic resource allocation, improving efficiency and reducing costs. In software development and testing, the modular and self-contained nature of containers allows for faster iteration and more problem-averse development. And finally, in the continuous integration and delivery pipelines, containers and container management tools allows automation, and lower overhead and complexity, enabling lower-threshold software deployment. Along with enabling cloud infrastructure as it exists today, the evolution of virtualization and containers in the software industry provide benefits across the board

A New Cryptographic Encryption Approach for Cloud Environment

Cloud security and trust management are an important issue in the cloud environment. Cloud computing is the result of the evolution of virtualization, service-oriented design, and the widespread adoption of involuntary and utility computing. Today, cloud computing is the fastest growing technical term and captures a global service-oriented market, so cloud computing service providers and cloud computing consumers need to maintain trust between them. In cloud security, if you discuss the security procedures of traditional IT information systems, designing security into cloud software during the software development life cycle can greatly reduce the cloud attack surface. With cloud computing providing Security as a Service (SAAS), security software is an important issue. From a cloud customer perspective, the use of security services in the cloud reduces the need for security software development. The requirements for security software development are transferred to the cloud provider. This work proposes a new cloud environment security and trust management algorithm, which uses the cryptosystem method to improve the single alphabet based on the concept of multi-letter cipher. Encryption and decryption is applied to plain text to encrypt text and cipher text for plain text conversion. In this work, the algorithm's power consumption, encryption and decryption throughput, and security analysis are also presented

Benchmarking the performance of hypervisors on different workloads

Many organizations rely on a heterogeneous set of applications in virtual environment to deliver critical services to their customers. Different workloads utilize system resources at different levels. Depending on the resource utilization pattern some workloads may be better suited for hosting on a virtual platform. This paper discusses a novel framework for benchmarking the performance of Oracle database workloads such as Online Analytical Processing (OLAP), Online Transaction Processing (OLTP), Web load and Email on two different hypervisors. Further, Design of Experiments (DoE) is used to identify the significance of input parameters, and their overall effect on two hypervisors, which provides a quantitative and qualitative comparative analysis to customers with high degree of accuracy to choose the right hypervisor for their workload in datacenters

Cloud Computing in Resource Management

Swiftly increasing demand of computational calculations in the process of business, transferring of files under certain protocols and data centers force to develop an emerging technology cater to the services for computational need, highly manageable and secure storage. To fulfill these technological desires cloud computing is the best answer by introducing various sorts of service platforms in high computational environment. Cloud computing is the most recent paradigm promising to turn around the vision of “computing utilities” into reality. The term “cloud computing” is relatively new, there is no universal agreement on this definition. In this paper, we go through with different area of expertise of research and novelty in cloud computing domain and its usefulness in the genre of management. Even though the cloud computing provides many distinguished features, it still has certain sorts of short comings amidst with comparatively high cost for both private and public clouds. It is the way of congregating amasses of information and resources stored in personal computers and other gadgets and further putting them on the public cloud for serving users. Resource management in a cloud environment is a hard problem, due to the scale of modern data centers, their interdependencies along with the range of objectives of the different actors in a cloud ecosystem. Cloud computing is turning to be one of the most explosively expanding technologies in the computing industry in this era. It authorizes the users to transfer their data and computation to remote location with minimal impact on system performance. With the evolution of virtualization technology, cloud computing has been emerged to be distributed systematically or strategically on full basis. The idea of cloud computing has not only restored the field of distributed systems but also fundamentally changed how business utilizes computing today. Resource management in cloud computing is in fact a typical problem which is due to the scale of modern data centers, the variety of resource types and their inter dependencies, unpredictability of load along with the range of objectives of the different actors in a cloud ecosystem

Towards multi-tenant cache management for ISP networks

The decreasing cost of storage and the advent of virtualization technology can allow Internet Service Providers (ISPs) to deploy multi-tenant caching infrastructures and lease them to content producers and Content Delivery Networks (CDNs). Serving content requests directly from the ISP network does not only reduce the delivery time, but also allows the ISP to optimize the network resources by controlling the placement and routing of content items. In this paper, we introduce a multi-tenant cache management approach that significantly reduces the bandwidth utilization of ISPs networks by pro-actively allocating caching space, leased by content producers and/or CDNs, and intelligently routing content to the end users. Using real content request traces, we show that the optimal solution to this problem can increase the cache hit ratio by 70.64% while reducing the bandwidth usage by 57.17% on average, compared to a commonly used reactive cache management scheme. These results provide a benchmark for the development of novel multi-tenant cache management strategies
