Abstract
Cloud computing is like a virtual computer city, providing the infrastructure to host your mission-critical applications without the burden of managing operational overhead. The reliability of any workload in a cloud environment depends on its architectural design. Here comes the foundational question: “Are you designing your workloads to be resilient?”. Resilience stands as a cornerstone for the stability of the workload along with safeguarding access to your sensitive data. The resilience of the infrastructure components is pivotal, especially when entrusted with the vital task of ensuring uninterrupted service. Based on Uptime Institute - the Global Digital Infrastructure Authority ‘s research in 2022, one in five organizations across the globe have faced ‘severe’ or ‘serious’ outages, and 60% of these outages have cost around $100,000 US dollars to the respective organizations. This paper explains the importance of designing and implementing a fault-tolerant design by exploring scenarios ranging from network connectivity to regional outages within data centers and cross-region environments. This research study will empower and prepare the readers for incident readiness by offering methods to reduce blast radius, protect the environment, and keep informed throughout incident lifecycles. It provides a design process flow for applications, databases, and traffic management, which form the nexus of user interaction. Additionally, it shares remediation strategies for resilience failover and guides on defining service level agreements for mission-critical applications. Testing the system’s resilience against failures is paramount, whether it is through actual disruptions or simulated scenarios. Exploring the architecture’s robustness on how to plan for failures with best practices by using architectural patterns and orchestration techniques plays a pivotal role in fortifying the system against adversities. This research provides a conceptual design guiding practitioners towards safeguarding the integrity and continuity of the mission-critical cloud infrastructure ecosystems from unplanned outages and hardware failures.
