Abstract: This paper aims to advance high availability in microservices by a novel approach called recursive redundancy zoning (RRZ). This research adopted an integrated approach to high availability by enhancing the chain oriented load balancing method. It adopts a combination of redundancy nesting and containerisation to ensure early fault detection and isolation. An empirical and concrete insight is provided in this research that indicated that the RRZ approach provides the best performance in terms of response time, load balancing and scalability. Comparison of this novel approach with existing approaches shows an improvement in availability. Since the experimental tests and evaluations carried out was based on a simulated environment, further research is ongoing to evaluate the performance of the RRZ approach in enterprise cloud environment. This research with further refinements could be a standard for design of mission critical information systems that require a high level of stability under unreliable load conditions.
