IMPLEMENTING PRIVATE CLOUD USING OPEN SOURCE SOFTWARE

Abstract

This work is based on setting up private cloud to be used as a platform for deploying various applications over it. In this work a private cloud has been deployed in LANS lab, DTU using Apache CloudStack Infrastructure as Service (IaaS) with ActiveState Stackato Platform as a Service (PaaS) over it. The main cloud setup is used to provide a Health Secure Service for a NFC based healthcare service as suggested in [1]. The Health Secure service provides security as a service for a secure interaction between patient and doctor. The application assumes that patient records are retained with him on a personal electronic device like mobile. In case the records are lost they can be retrieved from the backup of records maintained in the cloud. The cloud provides a PaaS application where patients and doctors can be registered and their security information as well as access control information can be retained on a SQL database. The patient or any hospital staff will connect to private cloud for key retrieval or information retrieval of patient. If hospital staff wants to add new medical record into system then it should be done in very secure way. For this purpose private cloud is necessary which will deliver on-demand service to authenticated devices in a secure manner and users can utilize a shared and elastic infrastructure. Another positive aspect of cloud computing is scalability. If there is peak load or high traffic for a site, cloud can handle easily without any additional hardware infrastructure & without disturbing user's normal work. Another advantage of cloud is fault tolerance, i.e. hardware failure can be easily traced out and rectified.
