Cloud database management systems (DBMSs) often decouple database instances from physical storage to provide reliability and high availability to users. This design can robustly handle a single point of failure, but needs substantial effort to attain good performance. In this paper, we analyze the decoupled architecture and present important optimization issues that we faced in implementing the design...
During the spring and summer of 2017, the guest editors of this special issue conducted an asynchronous panel discussion among several experts concerning the nature of cloud-native applications.
The drastic increase in the commodity computer and network performance for the last generation has a resultant of faster hardware and more sophisticated software. But, the supercomputers of the current generation are still incapable of solving the current problems in the field of science, engineering, and business. This problems arises as a single machine cannot facilitate the availability of various...
This paper focuses on the theoretical modeling of sensor cloud, which is one of the first attempts in this direction. We endeavor to theoretically characterize virtualization, which is a fundamental mechanism for operations within the sensor-cloud architecture. Existing related research works on sensor cloud have primarily focused on the ideology and the challenges that wireless sensor network (WSN)-based...
This paper introduces the performance analysis of OpenStack Cloud with the commodity computers in the big data environments. It is necessary to analyze the performance of virtual system in cloud infrastructure with the commodity computers to identify effective and efficient system for processing big data. To determine performance measures, virtual systems were created in the Openstack cloud and Hadoop...
A reference architecture guides an organization with best-practice knowledge about existing architectures, including an elaboration of the organization's mission, vision and strategy of a specific domain. Current e-learning architectures, however, focus on the theoretical framework of the application layer, service layer and database engineering while in reality, a networking layer is required for...
Cloud computing technologies have significantly changed the way in which organizations implement their information technology infrastructure. It is a new paradigm that turned the long-held promises of computing services into reality. It allows organizations to focus on their business with minimal effort placed upon building, managing and maintaining their IT requirements. However, security and incident...
With the appearance of distributed computing, associations are hoping to move their Customer Relationship Management (CRM) applications from an On-Premise environment or we can say local servers to an On-Demand environment that is on cloud server. On-Premise environment is when association has the framework and programming inside their system. In On-Demand environment, outsider has the base and programming...
The use of digital content is increasing day after day and now it is an essential element of our day today life. The amount of stored information is so huge that it is highly difficult to manage the content especially in a distributed cloud environment. There are many open source software solutions available in cloud to handle huge amount of digital data. However none of these solutions addresses...
Cloud computing has become an extremely attractive area of research and practice over the last few years. However, there are many concerns over privacy of shared documents while adopting and using public cloud solutions. Private cloud solution is useful for organizations to implement their own privacy policies. Through this paper we propose a method to upload privacy preserving application on private...
Challenges in bioinformatics include tools to treat large-scale processing, mainly due to the large volumes of data generated by high-throughput sequencing machines. Besides, many of these tools are not user friendly, and do not distribute their workloads properly. In federated cloud environments, even though services and resources are shared and available online, the processes of a workflow execution...
We propose ‘VDroid’ a lightweight virtualization architecture based on operating system level virtualization technique for a smartphone. We modify Condroid architecture by addition of a system service called KSMManagerService to the host android framework and KSM daemon to kernel. We define the workflow, running criteria and detail integration of both KSMManagerService and KSM daemon. The results...
DIGITAL transformation is a major challenge for many organizations. IT managers in particular not only wonder what the next digital trends in their industry will be, they also need to understand how today's IT organizations will change in light of digital transformation. I will first discuss some foundations of digital transformation and will then present 10 theses on how digital transformation will...
Wisdom aligns with technology is the key factor for sustainable business development. By increasing amount of public and private data, organizations need to find new solutions to manage data and information which lead to knowledge, better decision making, and value. In the big data-bang, smart organization surfing on-line technology and start planning big data strategy. However, many organizations...
Information security management is a complicated task in cloud environment. Cloud service layers and multi-tenant architecture have created a complicated environment for developing and managing a monitoring and incident response environment in organizations. The main goal of this paper is to receive and analyze events from OpenStack environment. Events and system logs are received from OpenStack environment...
Today's era is cloud era. Maximum organizations already are using cloud services for their data storage and many more looking forward to shift on cloud computing. Data stored on cloud data servers by data owners or organization should be accessible to privilege users. On cloud enormous data is stored but when authorized users wants to access specific data of his interest resource matchmaking is required...
Cloud Computing (CC) is a computing infrastructure paradigm that provides elasticity to software or hardware solutions on organizations, and is more powerful than traditional architectures for storage, processing, and distribution of data. Meanwhile, Enterprise Architecture (EA) describes organization's structure and allows assurance its objectives. Recent studies face to integration of EA with CC...
Cloud providers can be organized in associations of multiple clouds with the objective of achieving all canonical properties expected from the cloud computing paradigm. However, problems inherent to the resource offering and consumption arise as one limitation to furnish cloud computing at its full extent. This work describes a multiple cloud architecture that utilizes a tournament model to promote...
Cloud Computing is a Service Delivery Mechanism. Computing resources are delivered as a service over the network. These services are Scalable, Autonomous, and Cost effective in nature. Cloud Computing is responsible for the exponential growth of IT Industry. In spite of having so many advantages it has various security challenges that cannot be ignored. In order to make the Cloud Computing all the...
In the last years, the Cloud services market experienced an extremely rapid growth, which may lead to severe scalability problems. Therefore, in order to cope with the resource capacity limits of a single Cloud provider, as well as to address the vendor lock-in problem associated to the choice of a single proprietary Cloud solution, the concept of federating multiple heterogeneous organizations is...
