Healthcare is one of the most important basic foundations in every country including Thailand. Using information technology has recently been the trends in healthcare services worldwide. Even though there are many existing hospital information system (HIS) deployed in Thailand, there is no defined standard that aims at supporting a growing demand of information exchange. Currently, healthcare data...
Optimizing cloud provisioning for scientific workflow applications is a challenging problem, since the workflows generally contain dependency between tasks and require specific deadlines. Usually, cloud providers offer many options to the consumers. These options include the number of virtual machines, the type of each virtual machine and the purchasing method for each machine. Currently, cloud provisioning...
This research proposes a manufacturing data analysis framework in the form of computing blocks. The aim is to identify the parameters/attributes that affect the production yield as well as the root cause of the manufacturing problems. The framework is designed to be flexible and exploit the cloud as a computing platform. The manufacturing data are obtained from the database of the production lines...
To help SMEs game service provider in supporting a large-scale of multi-players online games (MOGs), a distributed game server deployed in multiple zones has been widely used. Because of the demand of MOGs is dynamically changing over time, game system in some zones may experience the server overloads. Existing load balancing algorithm has been implemented to solve this problem by transferring the...
This paper reports on the development of the Cloud Oriented Data Analytics (CODA) framework which has functions for composing, managing, and processing workflows for data analytics in cloud computing. The framework provides a number of reusable software components for data analytics to users which can be composed as workflows through well-known workflow composers, e.g., RapidMiner, Taverna, and JOpera...
Cloud has been the main technology utilized as a high performance computing (HPC) platform. The characteristics of cloud can satisfy a large scale processing required by scientific applications, which are mostly compute-intensive with big data. Cloud can also reduce the computing cost through sharing and virtualizing of resources. In the cloud, a large number of virtual machines (VM) can be generated...
One of the most important characteristics of a cloud system is elasticity in resources provisioning. Cloud fabric often composes of massive and heterogeneous types of resources allowing the sciences and engineering applications in many domains to collaboratively utilize the infrastructure. As the cloud systems are designed for a large number of users, a large volume of data, and various types of applications,...
A cloud technology has emerged as a prominent workflow computing infrastructure. The need arises to optimize the allocation of resources to cloud provider's customers. An appropriate number of VMs must be created along with the allocation of supporting resources. Moreover, commercial clouds may have many different purchasing options. Finding optimal provisioning solutions is thus an NP-hard problem...
