Abstract

The move to the cloud raised expectations to finally leave behind on-premises silos and all the issues that accompany them. The complexity of hybrid scenarios, cloud provider lock-in situations and heavy dependencies on centralised cloud services take problems to a next level. Large and complex cyber systems, often encompassing both legacy and cloud, are difficult to maintain and operate, particularly in terms of cyber security. Investing in cyber resilience brings benefits not only in cyber security but also in building, maintaining and operating these systems. This paper introduces a practical model for building resilience within cyber system architectures. The main goal of the model is to reduce complexity and keep distributed large cyber environments manageable. As an architectural approach, the structure of the model extends from the enterprise level through the system level to the component level. The model is accompanied by a selection of basic patterns for building robust and resilient cyber systems. Its applicability is illustrated by some practical use cases in typical on-premises and cloud scenarios.
