Clustering composite SaaS components in Cloud computing using a Grouping Genetic Algorithm

Recently, Software as a Service (SaaS) in Cloud computing, has become more and more significant among software users and providers. To offer a SaaS with flexible functions at a low cost, SaaS providers have focused on the decomposition of the SaaS functionalities, or known as composite SaaS. This approach has introduced new challenges in SaaS resource management in data centres. One of the challenges is managing the resources allocated to the composite SaaS. Due to the dynamic environment of a Cloud data centre, resources that have been initially allocated to SaaS components may be overloaded or wasted. As such, reconfiguration for the components’ placement is triggered to maintain the performance of the composite SaaS. However, existing approaches often ignore the communication or dependencies between SaaS components in their implementation. In a composite SaaS, it is important to include these elements, as they will directly affect the performance of the SaaS. This paper will propose a Grouping Genetic Algorithm (GGA) for multiple composite SaaS application component clustering in Cloud computing that will address this gap. To the best of our knowledge, this is the first attempt to handle multiple composite SaaS reconfiguration placement in a dynamic Cloud environment. The experimental results demonstrate the feasibility and the scalability of the GGA

Implementing SaaS Solution for CRM

Greatest innovations in virtualization and distributed computing have accelerated interest in cloud computing (IaaS, PaaS, SaaS, aso). This paper presents the SaaS prototype for Customer Relationship Management of a real estate company. Starting from several approaches of e-marketing and SaaS features and architectures, we adopted a model for a CRM solution using SaaS Level 2 architecture and distributed database. Based on the system objective, functionality, we developed a modular solution for solve CRM and e-marketing targets in real estate companies.E-Marketing, SaaS Architecture, Modular Development

Business and technical requirements of Software-as-a-Service: Implications in portuguese enterprise business context

Software-as-a-Service (SaaS) is a viable option for some companies bearing their business processes. There is a considerable adoption rate, with companies already using more than two services for over two years. However, while some companies have plans to put more business processes supported by these services in the near future, others do not know if they will. They have several concerns regarding the software providers service level. These concerns are mainly technical and functional issues, service availability and payment models. There are major changes compared to the traditional software that have implications on how the software is developed and made available to the users. The existing research addresses specific aspects and few studies give a broader view of the implications of SaaS for anyone who develops and provides software, and also for those who consumes it as an end user. What are the real needs of the Portuguese market? What fears and what is being done to mitigate them? Where should we focus our attention related to the SaaS offering in order to create more value? Thus, to analyze these questions four exploratory case studiesare used to assess the possible implications of SaaS on software developers or software providers based in Portugal and also on end-users. This article appears in the context of a realistic and deep research that includes the involvement of managers, leaders and decision makers of Portuguese companies, to realize what actually constitutes a problem in SaaS and what effectively companies would like to have available in this offer. The results of this study reveal that SaaS effectively constitutes a very interesting and solid solution for the development of Portuguese companies, however there is a lack for greater efforts particularly in terms of customization for each customer (tenant) and integration with the back-end on-premise applications

School finance in Vermont: balancing equal education and fair tax burdens

An education finance system that is constitutional under the Brigham ruling mandates sacrifices on the part of taxpayers for a public good—educated citizens. It remains to be seen if current proposals can make that sacrifice more palatable or ensure that those bearing the burden have the most stake in the outcomes of the system.Public schools - Vermont ; Local finance - Vermont ; Taxation - Vermont ; Education - Vermont

Hollywood east?: film tax credits in New England

Five of the six New England states now provide tax credits or other financial incentives to attract producers to film on location. This policy brief discusses whether these incentives attract more production, and whether they are cost-effective in creating jobs. It focuses on the use of one major incentive: film tax credits.Tax credits - New England ; Motion picture industry - New England

SOFTWARE DEVELOPMENT BUSINESS MOVING TOWARDS A UNIFIED COLLABORATIVE SYSTEM IN IT. SAAS MAY BE THE NEW ORIENTATION.

In this paper we will present an alternative way of programming. Our opinion is that, in the next few years, software development business will suffer serious changes. Software vendors will adopt SaaS (Software as a Service) as the new way of selling their products. We will try to guide you through the basic concepts of this relatively new domain. The article also includes a brief description of an application, developed indoor but using SaaS applications for some of its modules. In the end we want to make an SWOT analysis of the opportunity of using SaaS.Software as a service (SaaS), informatics, business, vendors, new technology.
