Cloud services are helping with the management and organizational placement of organizational IT resources by providing products that are malleable, versatile, and inexpensive. But as people start using cloud-based applications in areas that cannot afford any disruption in healthcare, finance, public safety and defense, the need for sturdy and reliable systems becomes critical. For critical business processes, performance disruption, availability problem or failure conditions, risk exposure that causes loss, brand deterioration, or death is not acceptable. Durability architectures are built to avoid, accommodate and restore disruptions resulting from equipment breakdown, cyber- attacks, calamities or surge in workload. This paper focuses on fault tolerance, replication of data, disaster recovery, and distributed systems, as methods that can be used to construct reliable systems. It also explores newer trends like Artificial Intelligence, Machine Learning, and Edge Computing that allow the continuous monitoring, analytics, and automated recovery. The issues are presented and discussed in detail, and the trends that include on-premise and cloud environments, compliance issues and evolving threat landscape are highlighted. Specific steps to increase business productivity when using business intelligence, credibility of information, and adaptability are described. This work positions resilience as a competitive advantage underpinning the capabilities of cloud-oriented organisations to navigate the challenges of current technology environments cohesively.
