In this paper we study entrepreneurship and firm survival, using as our empirical backdrop the Indian software service industry. We develop a model that has contrasting predictions about the impact of the scale of entry on firm performance, after conditioning on lagged output. We test predictions of the model. We find that current size positively influences the firm survival but initial size...

Traditional software applications are typically customized before being delivered to a client. This customization was a paid service delivered by software development organisations. With the growing demand of applications delivered with a SaaS model, software development organisations are increasingly responding with the migration of traditional applications to a multi-tenant SaaS deployment mo...

The main objective of this study is to investigate the impact of corporate research and development (R&D) activities on firm performance. To this end, the stochastic frontier technique is used on a unique balanced longitudinal dataset comparing top global software enterprises over the period 2005-2010. The software companies is divided into system software companies, application software compan...

Cloud computing is a kind of distributed computing over the internet i.e. it can run a program or application on more than one computer at the same time. It is divided into three categories namely: (i) Infrastructure as a service (IaaS), (ii) Platform as a service (PaaS), and (iii) Software as a service (SaaS). Software as a service is a kind of service which provides many benefits to the servi...

Cloud technology is evolving at a rapid pace with innovation occurring throughout the software stack. While updates to Software-as-a-Service (SaaS) products require a simple push of code to the production servers or platform, updates to the Infrastructure-as-a-Service (IaaS) or Platform-as-a-Service (PaaS) layers require more intricate procedures to prevent disruption to services at higher abst...

Cloud computing has heralded many advantages including self-service, elasticity, pay as you go, improved accessibility to computation resources, and ease of deployment and deployment automation. However, to extend those advantages to a larger audience, higher-level abstractions such as Software as a Service (SaaS) or Platform as a Service (PaaS) are needed. This paper presents Stratos, which is...

Abstract This paper proposes the methods of the operation-oriented software availability measurement and assessment. Considering the difference of the software failure-occurrence phenomena and the restoration characteristics between the testing and the operation phases, we first introduce the environmental factors into the existing Markovian software availability model. Next we discuss the stoc...

We argue that the software-as-a-service (SaaS) paradigm has advantages as a sustainable delivery method for scientific software. We report on our experience developing and delivering the Globus Online research data management system using SaaS approaches. We note problems encountered and, for some problems, solutions that appear effective. We also identify conditions that we consider necessary ...

This paper proposes a highly automated mechanism to build an undo facility into a new or existing system easily. Our proposal is based on the observation that for a large set of operators it is not necessary to store in-memory object states or executed system commands to undo an action; the storage of input data is instead enough. This strategy simplifies greatly the design of the undo process ...
