KVM and XenServer are popular choices for hypervisor technology and recommended for most use cases. Linux container technology such as LXC is also supported for scenarios where users wish to minimize virtualization overhead and achieve greater efficiency and performance. In addition to different hypervisors, OpenStack supports ARM and alternative hardware architectures[14] [16]. An Users OpenStack OpenStack example primarily is Compute of designed some ...

... approach was tested using three physical servers as shown in figure 3. In the setup, the first server hosts a web service and the second server hosts a database service as illustrated in figure 14.

The implementation of the system requires only the creation, execution and spinning up of virtual machine instances by specifying the details and required specification in openstack as demonstrated in figure 10. Any direct manipulation of the physical servers or hardware equipment is not necessary. ...

... From a functional and architectural perspective, a number of studies have compared OpenStack to other IaaS solutions and concluded it as being massively scalable and agile as discussed in [19,20]. For instance, Bashir et al. [21] present a case study using OpenStack to demonstrate the feasibility of migration from a traditional web service to a cloudbased solution. A similar study to analyze migration of scientific applications to a cloud-based environment concludes that cloud-based solution results in negligible performance degradation [22]. ...
Cloud adoption has significantly increased using the infrastructure-as-a-service (IaaS) paradigm, in order to meet the growing demands of computing, storage, and networking, in small as well as large enterprises. Different vendors provide their customized solutions for OpenStack deployment on bare metal or virtual infrastructure. Among these many available IaaS solutions, OpenStack stands out as being an agile and open source platform. However, its deployment procedure is a time taking and complex process with a learning curve. This paper addresses the lack of basic infrastructure automation in almost all of the OpenStack deployment projects. We propose a flexible framework to automate the process of infrastructure bring-up for deployment of several OpenStack distributions, as well as resolving dependencies for a successful deployment. Our experimental results demonstrate the effectiveness of the proposed framework in terms of automation status and deployment time; that is, reducing the time spent in preparing a basic virtual infrastructure by four times, on average.
With technological developments and the emergence
of the Internet, other methods of trade had to emerge that differ
from traditional commerce, so what is known as e-commerce
appeared, and to keep pace with these developments it was
necessary to know what e-commerce is and how to use it, it is the
process of buying or selling products through electronic means,
such as The Internet or other electronic services, and the need for
e-commerce emerged from the need to use computers more
efficiently in banks and companies, and with the increase in
competition, it was imperative for organizations to work on ecommerce in order to increase customer satisfaction and
exchange information. In our research, we prepared a
questionnaire containing a set of questions and gave them to
more than 150 people from different categories and disciplines to
find out their opinions on this topic, and we benefited from the
data analysis program (SPSS). Then we collected the data and
then wrote the conclusions and reached what we reached, and
then we made suggestions to address the problems faced by
digital marketing. Since the outbreak of the Coronavirus (Coved
19), more than 85% of customers around the world are shopping
via the Internet, so there is no doubt that despite the setbacks in
various sectors around the world; On top of them are the
commercial sectors, but there are many other sectors that have
made the most of this crisis, and perhaps the most prominent of
them is "e-commerce", which has witnessed an increasing
demand in light of customers' fear of being in crowded places.
Cloud computing is one of the frontier technologies, which over the last decade has gained a widespread commercial and educational user base. OpenStack is one of the popular open source cloud management platforms for establishing a private or public Infrastructure-as-a-Service (IAAS) cloud. Although OpenStack started with very few core modules, it now houses nearly 38 modules and is quite complex. Such a complex software bundle is bound to have an impact on the underlying hardware utilization of the host system. The objective is to monitor the usage of system resources by OpenStack on commodity hardware. This paper analyzes the effect of OpenStack on the host machine's hardware. An extensive empirical evaluation has been done on different types of hardware, at different virtualization levels and with different flavours of operating systems comparing the CPU utilization, memory consumption, disk I/O, network, and I/O requests. OpenStack was deployed using Devstack on a single node. The novel aspect of this work is monitoring the resource usage by OpenStack without creating virtual machines on commodity hardware. From the analysis of data, it is observed that standalone machine with Ubuntu server operating system is the least effected by OpenStack and thereby has more available resources for computation of user workloads.

Cloud computing is one of the frontier technologies, which over the last decade has gained a widespread commercial and educational user base. OpenStack is one of the popular open-source cloud management platforms for establishing a private or public Infrastructure-as-a-Service (IAAS) cloud. Although OpenStack started with very few core modules, it now houses nearly 38 modules and is quite complex. Such a complex software bundle is bound to have an impact on the underlying hardware utilization of the host system. This paper analyzes the effect of OpenStack on the host machine’s hardware. For this purpose, an extensive empirical evaluation has been done on different types of hardware, different virtualization levels and with different flavors of operating systems comparing the CPU utilization, and memory consumption. OpenStack was deployed using Devstack on a single node. From the results it is evident that standalone machine with Ubuntu server operating system is the least affected by OpenStack and thereby has more available resources for computation of user workloads.
