a multi tenant web application framework for saas
International Conference on Cloud Computing, 2012Co-Authors: Min ChoiAbstract:Software as a Service (SaaS) is a software delivery model in which software resources are accessed remotely by users. Enterprises find SaaS attractive because of its low cost. SaaS requires sharing of application servers among multiple tenants for low operational costs. Besides the sharing of application servers, Customizations are needed to meet requirements of each tenant. Supporting various levels of configuration and Customization is desirable for SaaS frameworks. This paper describes a multi-tenant web application framework for SaaS. The proposed framework supports runtime Customizations of user interfaces and business logics by use of file-level namespaces, inheritance, and polymorphism. It supports various client-side web application technologies.

product Customization and price competition on the internet
Management Science, 2003Co-Authors: Rajiv M Dewan, Bing Jing, Abraham SeidmannAbstract:The Internet provides an unprecedented capability for sellers to learn about their customers and offer custom products at special prices. In addition, Customization is more feasible today because of advances in manufacturing technologies that have improved sellers' manufacturing flexibility. We first develop a model of product Customization and flexible pricing to incorporate the salient roles of the Internet and flexible manufacturing technologies in reducing the costs of designing and producing tailored consumer goods. We show how a monopoly seller may earn the highest profits by producing both standard and custom products and can raise prices for both types of products as Customization and information collection technologies improve.Simultaneous adoption of Customization in a duopoly reduces the differentiation between their standard products but does not intensify price competition. Compared with a two-facility monopolist, the duopoly may underinvest in Customization. Consumer surplus improves after sellers adopt Customization but does not monotonically increase as Customization technologies advance. When firms face a fixed entry cost and adopt Customization sequentially, the first entrant always achieves an advantage and may be able to deter subsequent entry by choosing its Customization scope strategically.

product Customization and price competition on the internet
2001Co-Authors: Rajiv M Dewan, Bing Jing, Abraham SeidmannAbstract:The Internet provides an unprecedented capability for sellers to learn about their customers and offer custom products at special prices. Advanced manufacturing technologies have improved sellers' manufacturing flexibility. To examine how these advances affect sellers' products and pricing,we first develop a model of product Customization and flexible pricing to incorporate the salient roles of the Internet and flexible manufacturing technologies in reducing the costs of designing and producing tailored consumer goods. A monopoly seller may earn the highest profits by producing both standard and custom products. Surprisingly, the monopoly can raise his prices for both standard and customized products as Customization and information collection technologies improve. Simultaneous adoption of Customization in a duopoly reduces the differentiation between their standard products but does not intensify price competition. Compared with a two-facility monopolist, each duopolist may under-invest in Customization. Consumer surplus improves after sellers adopt Customization but does not always increase as technologies advance. When firms face a fixed entry cost and adopt Customization sequentially, the first entrant always achieves a profit advantage and may even deter the entry of the late entrant by choosing his Customization scope strategically.

the effect of service Customization on customer loyalty towards mobile network operator in pakistan the mediatory role of perceived quality value customer satisfaction and trust
Social Science Research Network, 2020Co-Authors: Nausheen Ashraf, Danish Ahmed SiddiquiAbstract:Companies often engage in product and service Customization as part of a differentiation strategy, as it represents a source of competitive advantage. However, its effect on customer relationships as well as contingencies for its effective application is not well understood. In Particular, how it has an impact on the loyalty of a brand or company is still an open question. This paper modified Coelho and Henseler (2012) model to explore the influence of service Customization on customer loyalty in the cellular phone operators. We hypothesized that Customization increased product quality that would increase perceived value. The increased value would lead to customer satisfaction and ultimately loyalty. Customization also has effects on loyalty by increases in customer trust. Empirical validity was established by conducting a survey using a close_ended questionnaire. Data was collected from 305 respondents and analyzed using confirmatory factor analysis and structured equation modeling. The results suggested Customization has a direct but inverse effect on loyalty. Moreover, it has a significant and positive effect on perceived quality as well as customer satisfaction. Perceived quality positively affects perceived values and Customer satisfaction. On focusing on the other channel, we found a negative effect of Customization on trust. However trust positively affects loyalty, hence trust plays an inverse role in mediating Customization and loyalty nexus. Lastly, customer satisfaction has a positive effect on both loyalty and trust. Customization has both direct and mediated effects on customer loyalty and interacts with the effects of customer satisfaction and customer trust on loyalty. Hence, the finding implies that Customization has both direct and mediated effects on customer loyalty and interacts with the effects of customer satisfaction and customer trust on loyalty. This paper fills an important gap in the knowledge of Customization outcomes, and clarifies under which circumstances Customization is most effective. These results help managers to decide upon resource allocation to enhance customer satisfaction, trust, and loyalty.

Mass Customization: Reflections on the State of the Concept
International Journal of Flexible Manufacturing Systems, 2004Co-Authors: F T PillerAbstract:The opportunities of mass Customization are acknowledged as fundamentally positive by theoretical and empirical studies for many years. Many companies are already operating on this new business model successfully. But most of them are rather small start-ups which utilize the novelty effect of mass Customization to enter mature markets. Large scale mass Customization operations are still limited to a few examples. The objective of this paper is to analyze the recent state of mass Customization practice by answering four basic questions which are frequently raised by managers and scholars when talking about the challenges of this approach: Do customers need customized products? If yes, what prevents them from purchasing these offerings? Do we have the enabling technologies for mass Customization? And why do many firms fail during and after the introduction of mass Customization? To answer these questions, this paper develops twelve propositions. These refer to terminological problems, a shortage of reliable information about the real demand for customized products in various markets, the state of implementation of configuration technologies, lack of management knowledge about organizational and strategic capabilities of mass Customization operations, and the demand for sincere change management activities. These issues may explain why the present state of practical implementation of mass Customization lacks behind the description and discussion of the phenomenon in the management literature.

does mass Customization pay an economic approach to evaluate customer integration
Production Planning & Control, 2004Co-Authors: F T Piller, Kathrin M Moeslein, Christof M StotkoAbstract:Keywords Mass Customization, flexible manufacturing, customer integration, economies, cost and profit drivers Abstract. The paper provides an integrated view of value creation in mass Customization-based production models. While flexible manufacturing technologies are often seen as the main enabler of mass Customization, we argue that modern information technologies play a similar important role. Their significance is based on enabling a distinctive principle of mass Customization efficiently: customer integration into the produc- tion processes. The customer is integrated into value creation during the course of configuration, product specification and co-design. Customer integration is often seen as a necessity and source of additional costs of Customization. However, we argue in this paper that customer integration may also be an important asset to increase efficiency and could pave the way for a new set of cost-saving potentials. We coin the term 'economies of integration' to sum up these saving potentials. Economies of integration arise from three sources: (1) from post- poning some activities until an order is placed, (2) from more

customer interaction and digitizability a structural approach to mass Customization
2002Co-Authors: F T PillerAbstract:Enterprises in all branches of industry are being forced to react to the growing individualization of demand, yet, at the same time, increasing competitive pressure dictates that costs must also continue to decrease. Companies have to adopt strategies which embrace both a closer reaction to the customers’ needs and efficiency. Mass Customization meets this challenge by offering individually customized goods and services at mass production efficiency. However, while Mass Customization has already been discussed in the literature for more than a decade, increased practical implementation of this strategy can been found in business only within the last years. This time lag may be explained by the fact that only since few years sufficient technologies exist to handle the information flows connected with mass Customization. Especially as mass Customization enters more and more consumer markets, new Internet technologies can be seen as its main enabler. To connect strategies discussed in e-business with the field of mass Customization, the paper deploys a structural approach to create mass customized concepts within electronic business.

from economies of scale towards economies of customer interaction value creation in mass Customization based electronic commerce
Bled eConference, 2002Co-Authors: Kathrin M Moeslein, F T PillerAbstract:Mass Customization is seen more and more as an application of electronic commerce rather than a manufacturing approach. The paper sets a framework for value generation in mass Customization based business models. Traditionally, mass Customization was argued to be possible due to the capabilities of modern manufacturing technology. We argue that these capabilities are supplemented by a new set of economies arising not from new possibilities in the fulfillment system, but from a better knowledge position and switching costs resulting from the direct interaction with each customer provided by innovative applications of electronic commerce. By examining and structuring the underlying economic principles of mass Customization, not only the limits and constraints, but also the benefits of this competitive approach will be better understood. For better planning mechanisms, the value and costs of a single process have to be known. In this context, we want to provide a starting point for further exploration.

Thread-level resource consumption control of tenant custom code in a shared JVM for multi-tenant SaaS
'Elsevier BV', 2021Co-Authors: Makki Majid, Landuyt, Dimitri Van, Lagaisse Bert, Joosen WouterAbstract:Software-as-a-Service (SaaS) providers commonly support Customization of their services to allow them to attract larger tenant bases. The nature of these Customizations in practice ranges from anticipated configuration options to sophisticated code extensions. From a SaaS provider viewpoint, the latter category is particularly challenging as it involves executing untrusted tenant custom code in the SaaS production environment. Proper isolation of custom code in turn requires the ability to control resource consumption of each tenant. In current practice, OS-level virtualization tools such as hypervisors or containers are predominantly used for this purpose. These techniques, however, constrain the number of tenants that a single node can cost-effectively accommodate. Furthermore, additional overhead will be incurred for (un)marshaling objects and possibly a network round-trip of data when these techniques are applied. In this paper, we present a practical solution for thread-level resource consumption control of tenant-provided custom code. This solution provides control mechanism for four types of resources, namely CPU, memory, network and storage. Usage data are gathered using the Java Resource Consumption Management API (JSR-284). In case of CPU and memory, where this API is not capable of imposing limits, both the Java Runtime Environment (JRE) bytecode and tenant code are instrumented with usage control checkpoints which ensures that CPU and memory usage of tenants remain within their Service-level Agreements (SLA) limits. Our experiments show that the proposed solution outperforms containers in terms of tenant accommodation capacity and performance overhead. It is shown that 84 times more tenants can be accommodated on a single node when our solution is adopted while, at the same time, the performance overhead of the control mechanism is less than hosting the tenant code as a remote process.keywords: SaaS, Customization, Multi-tenancy, Resource management, Tenant isolation, JR
