Why multi-tenancy is key to successful and sustainable softWare-as-a-service (saas)

Appendix Proof of Lemma 1: We first provide the complete parameter regions and the corresponding consumer equilibrium outcome: (I) Unpatched On-premises only (0 < v u < 1): (A) δ ≤ 1 − c p (i) p ≤ p s (1 − c p)/δ and α ≤ α B ; (ii) p s (1 − c p)/δ < p ≤ p s /δ and α ≤ α A ; (B) δ > 1 − c p (i) p ≤ 1 − c p − δ + p s and α ≤ α B ; (ii) 1 − c p − δ + p s < p ≤ p s and α ≤ α C ; (iii) p s < p ≤ p s...

Understanding the formation of commitment in service-oriented outsourcing such as SaaS is important. We draw on the relational view to examine how client-provider collaboration and a client’s outsourcing management capability, that have hitherto been considered independently, can be combined to improve commitment. Empirical results from 169 firms supported most of our hypotheses. The results sh...

Understanding the antecedents and consequences of trust in an online and on-demand outsourcing context is important. This study explores the effects of service quality on trust, which in turn affects a client firm’s post-adoption use in SaaS. A research model was developed based on the dedication-constraint framework of social exchange theory to measure service quality, trust, and SaaS post-ado...

In this paper, we analyze software production problem profiles and their link to the organizational contexts of European software production units. The data used in our study contains more than 3800 observations representing software production units in the Information Technology (IT), Production, and Service sectors. Software production problems examined in our study include those associated w...

We use audited financial statements to examine claims that service-oriented architecture (SOA) leads to higher profits relative to traditional software delivery models. Specifically, we examine vendors that rely on the Software-as-a-Service (SaaS) pricing model, and compare their performance to other firms that still use the traditional perpetual license model. We find that, relative to their p...

Cloud interoperability is a new problem that is becoming evident as more cloud providers offer competing clouds and more enterprises migrate their applications into the cloud environments. However, for large enterprises the problem lies in enterprise software and middleware non-interoperability and overall complexity more than in the cloud providers incurred issues. In this paper we analyze clo...

Cloud computing supplies software, platforms, and infrastructures as a service (abbr. SaaS, PaaS, and IaaS, respectively) over a network connection. From a user’s perspective, resource efficiency and scalability can be improved through aligning a cloud-based application with the cloud environment. Running an existing software system on a cloud computing basis usually involves extensive reengine...
