Run-Time Support for Adaptive Heavyweight Services [chapter]

Julio C. Lopez, David R. O'Hallaron
2000 Lecture Notes in Computer Science  
By definition, a heavyweight network service requires a significant amount of computation to complete its task. Providing a heavyweight service is challenging for a number of reasons.  ...  In this paper we present a framework that allows us to build these kinds of adaptive heavyweight services.  ...  In this paper we describe a run-time system and its API for building heavyweight network services.  ...

Heavyweight or lightweight

Cong Liu, David Umphress
2008 Proceedings of the 46th Annual Southeast Regional Conference on XX - ACM-SE 46  
A major motivation of grid computing is to aggregate the power of widely distributed resources to provide services to users.  ...  Nowadays two kinds of software processes are frequently mentioned: heavyweight and lightweight.  ...  So the time for data transmission can be ignored.  ...

Keynote Abstract - On the Use of Quantitative Models for Open-World Software

2010 2010 15th IEEE International Conference on Engineering of Complex Computer Systems  
The author is indebted to Raffaela Mirandola, Giordano Tamburrelli, Danilo Ardagna for their insights and contributions to quantitative modeling.  ...  the whole lifecycle of an application: not only as development-time aids but also the run-time, where they become the central entities that support evolution and adaptation policies.  ...  At this stage, models come into play to support adaptation and evolution. xvii To achieve dynamic adaptation, we suggest adoption of a feedback control loop from the run-time environment back to the model  ...

Generative innovation: a comparison of lightweight and heavyweight IT

Bendik Bygstad
2017 Journal of Information Technology  
This paper proposes a simple terminology for understanding and dealing with two current phenomena; we suggest calling them heavyweight and lightweight IT.  ...  Our findings show that (i) generativity enfolds differently in heavyweight and lightweight IT and (ii) generativity in digital infrastructures is supported by the interaction of loosely cou-Manuscript  ...  Thanks also to the many informants for their time and engagement.

A Semantic IoT Early Warning System for Natural Environment Crisis Management

Stefan Poslad, Stuart E. Middleton, Fernando Chaves, Ran Tao, Ocal Necmioglu, Ulrich Bugel
2015 IEEE Transactions on Emerging Topics in Computing  
An EWS needs to support semantics to support contextawareness of crisis events in order to adapt information services and to support data and service interoperability.  ...  We use heavyweight semantics for top level W3C Web Ontology Language ontology models describing multileveled knowledge-bases and semantically driven decision support and workflow orchestration.  ...  The sensor context, such as space and time, can be represented in a richer semantic form, to better support conditional queries and to adapt data services to these contexts.  ...

Architectural alignment of process innovation and digital infrastructure in a high-tech hospital

Bendik Bygstad, Egil Øvrelid
2020 European Journal of Information Systems  
For practitioners, we show that lightweight IT can serve as a mediating technology in the configuration. ARTICLE HISTORY  ...  We found that (i) the careful deployment of lightweight IT in onsite configuration, loosely coupled from the infrastructure activities, allows for fast process innovation while leveraging the slow and  ...  It co-ordinated the porter service and other support services.  ...

IRI-h, a Java-based distance education system: architecture and performance

R. Maly, H. Abdel-Wahab, C. Wild, C. M. Overstreet, A. Gupta, A. Abdel-Hamid, S. Ghanem, A. Gonzalez, X. Zhu
2001 Journal on Educational Resources in Computing  
We describe our motivation and vision for a reimplementation of IRI that supports synchronous and asynchronous distance education.  ...  This new version, called IRI-h (h for heterogeneous), is coded in Java and executes on several different platforms.  ...  The one really significant problem we need to address is that of the gateway for heavyweight services and synchronous presentation of services.  ...
