Enhancing Availability of Marine Bigdata Repository with a New Fault Tolerance Technique

Abstract

System availability is one of the crucial properties of a dependable knowledge repository system in order to preserve and pull through from minor outages in a short timespan by an automated process. National Marine Bioinformatics System or NABTICS is a Marine Microbial Bigdata Repository that unites the integrated information on genomic sequence and associated metadata which projected to be a large and growing database as well as a metadata system for inputs of research analysis and solving community issues. Therefore, it is decisive to maintain the availability of the system by accurately detecting the failure in a timely manner and a prompt recovery action during the event of failure. The failure in any of NABTICS' system component can be devastating for the system causing the system is inaccessible for a period of time. In this paper, we integrated NABTICS with Cloud-based Neighbour Replication and Failure Recovery (NRFR) in order to enhance the availability of the system. We showed that the implementation resulted in better user experience with minimum system downtime as well as online database application is said to be highly available. Furthermore, NABTICS also performed better resource utilization and higher response application during runtime.
