A Unified Framework for Digital Delivery: Transition Strategies from Legacy to Cloud-Native Systems

Abstract

In this essay, the paradigm changes in cloud migration strategies—from lift-and-shift to full cloud-native transformation—is examined. By examining technology elements, organisational factors, and architectural patterns, the paper offers a comprehensive framework for comprehending and deploying cloud native infrastructure. The demands of contemporary analytics workloads, real-time processing needs, and the exponential expansion of data volumes are becoming more and more difficult for legacy data warehouse systems to handle, despite their decades of dependability. Cloud-native tactics are revolutionising how businesses link heterogeneous systems, manage processes, and provide uniform user experiences. In order to address the particular security needs of cloud-native systems, this paper looks at a range of privacy-enhancing and trust-centric tools and strategies. In particular, a range of solutions are discussed, including cloud-native endpoint security solutions for guaranteeing trust and resilience in dynamic contexts, runtime protection platforms for real-time threat detection and responses, and service mesh technologies for secure service-to-service communication. To improve trust and transparency in cloud-native security, the significance of threat detection and response systems, cloud-native security information and event management (SIEM) solutions, and network security are also discussed. To guarantee comprehensive security in a cloud-native architecture, we also provide an extensive case study that illustrates how security measures are implemented across many levels, including application, network, infrastructure, security, and compliance. Organisations may strengthen the security posture of their cloud-native implementations by looking at these privacy-enhancing techniques and technologies. This will lower risks and guarantee the reliability of their data and apps in the dynamic ecosystem of today's digital world.
