Another Approach to Service Instance Migration [chapter]

Nannette Liske, Niels Lohmann, Christian Stahl, Karsten Wolf
2009 Lecture Notes in Computer Science  
We present a novel approach to the behavioral (service protocol) aspects of instance migration.  ...  For long running services, it may even be necessary to change a service while instances are actually running and interacting with other services. This problem is referred to as instance migration.  ...  Acknowledgements Niels Lohmann and Karsten Wolf are funded by the DFG project "Operating Guidelines for Services" (WO 1466/8-1).  ...

Toward Middleware-Based Online Application Migration

Fang Deng, Qianxiang Wang, Jin Shao
2009 2009 33rd Annual IEEE International Computer Software and Applications Conference  
As an effective approach to maintain software system without interrupting the service, online migration has been applied for many goals, e.g. achieving a higher system performance, tolerating faults, and  ...  A J2EE application migration framework (JAMF) is developed to demonstrate the proposed approach. The experiments with two typical examples show that our approach is feasible and effective.  ...  • How can we move an application from one node to another while not interrupting the service and keeping the migration process transparent to the end users?  ...

Enhancing Performance of Applications in Cloud using Hybrid Scaling Technique

Madhukar Shelar, Shirish Sane, Vilas Kharat
2016 International Journal of Computer Applications  
Generally dynamic scaling is achieved by the conventional live VM migration technique to create additional VM instances, but VM migration spends CPU time and consumes large amount of IO and network traffic  ...  The proposed technique postpones live VM migration as long as possible with the help of vertical scaling technique to improve the performance of applications.  ...  In conventional horizontal scaling, VMs are migrated to create additional instances on the same or another host for load balancing.  ...

Aspect-Oriented Checkpointing Approach of Composed Web Services [chapter]

Soumaya Marzouk, Afef Jmal Maâlej, Mohamed Jmaiel
2010 Lecture Notes in Computer Science  
In fact, strong mobility enables a running BPEL process to be migrated from a host to another and to be resumed on the destination host starting from a previous execution state called also checkpoint which  ...  Thus, the proposed approach may be used for self-healing and self-adaptivity of composed Web services acting in case of failure or QoS violation.  ...  Aspect-Oriented Checkpointing of Composed Web Services Strong mobility of orchestration processes consists in interrupting all (or a subset of) their executing instances, migrating them to another node  ...

A CORBA Environment Supporting Mobile Objects [chapter]

Sang Choy, Markus Breugst, Thomas Magedanz
1999 Lecture Notes in Computer Science  
The objective is to develop a flexible, unified, prototypical CORBA environment, supporting both remote interactions and object migration, only by considering already existing CORBA services as a basis  ...  This paper is targeted for input to the new OMG Agent Special Interest Group and describes a way how to integrate object mobility into a CORBA environment.  ...  An instance of it has the ability to migrate from one physical network location to another without loosing its internal state.  ...

How to Supercharge the Amazon T2: Observations and Suggestions

Feng Yan, Lihua Ren, Daniel J. Dubois, Giuliano Casale, Jiawei Wen, Evgenia Smirni
2017 2017 IEEE 10th International Conference on Cloud Computing (CLOUD)  
Cloud service providers adopt a credit system to allow users to obtain periods of performance bursts without additional cost.  ...  This extension of the high performance transient period is combined with proactive migration to further take advantage of the initially assigned credits.  ...  One natural way to get new CPU credits is to migrate to a new instance. Migration is expensive: service is interrupted as AWS does not support live migration.  ...

Modeling for Dynamic Cloud Scheduling Via Migration of Virtual Machines

Wubin Li, Johan Tordsson, Erik Elmroth
2011 2011 IEEE Third International Conference on Cloud Computing Technology and Science  
However, current approaches are restricted to static scenarios, where changes in characteristics such as pricing schemes, virtual machine types, and service performance throughout the service life-cycle  ...  Our model can be applied in various scenarios through selections of corresponding objectives and constraints, and offers the flexibility to express different levels of migration overhead when restructuring  ...  We are also grateful to the anonymous reviewers for their constructive comments.  ...

Lightweight component-based scalability

Hussein Suleman, Christopher Parker, Muammar Omar
2008 International Journal on Digital Libraries  
A set of lightweight services and extensions were created to migrate and replicate services as the load changes.  ...  It can be argued that such distributed components also can be an enabler for scalability of service provision in medium to large systems.  ...  Migration may be defined as the movement of a service from one machine to another while replication is when a copy of the service is created on another machine.  ...

Elastic Application Container: A Lightweight Approach for Cloud Resource Provisioning

Sijin He, Li Guo, Yike Guo, Chao Wu, Moustafa Ghanem, Rui Han
2012 2012 IEEE 26th International Conference on Advanced Information Networking and Applications  
To evaluate our approach and implementation, we conducted experiments and collected performance data by comparing VM-based and EAC-based resource management with regards to their feasibility and resource-efficiency  ...  The experiment results show that our proposed EAC-based resource management approach outperforms the VM-based approach in terms of feasibility and resource-efficiency.  ...  The EAC migration requires the application instance to be stopped, transferring to another EAC in a target node, and then restart the application instance in the target node.  ...
