Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Cloud computing provides a dynamic model that provides many more
services to users, as well as organizations, that can purchase based on their
requirements. Cloud offers services such as storage for data, a platform for application
development and testing, providing an environment to access web services, and so on.
Common issues in a cloud environment are maintaining the application performance
with Quality of Service (QoS) and Service Level Agreement (SLA) provided by the
service providers to the organization. The major task done by the service providers is to
distribute the workload among multiple servers. An effective load-balancing technique
should satisfy the user requirements through efficient resource allocation in Virtual
Machines. A review of various LB techniques that result in overall performance and
research gaps is discussed in this paper.
