Based on Kumar (2024) and Corbari et al. (2024)
1. What are some of the main vendor lock-in issues the authors identify? How would you mitigate them? According to Kumar (2024), vendor lock-in manifests primarily through Technical and Organizational obstacles.
- Technical Issues: The use of proprietary APIs and non-standard data formats creates high switching costs. Once an organization integrates deeply with a specific cloud provider’s ecosystem (e.g., using AWS Lambda or proprietary databases), migrating to a different DR provider becomes technically prohibitive due to compatibility issues.
- Organizational/Legal Issues: Restrictive contracts and the lack of interoperability standards further bind organizations to a single vendor.
Mitigation Strategies: To mitigate these risks, I would recommend a Multi-Cloud Strategy combined with Containerization (e.g., Docker/Kubernetes). By abstracting the application layer from the underlying infrastructure, organizations can move workloads between providers with minimal friction. Additionally, enforcing the use of Open Standards and avoiding proprietary PaaS (Platform as a Service) features where possible ensures that the DR solution remains portable.
2. What are some security concerns with the modern cloud? How can these be mitigated? A major security concern in modern cloud environments is the loss of visibility and control over the underlying infrastructure. However, a more subtle but critical concern identified by Corbari et al. (2024) is the complexity of dependencies. In complex cloud environments, it is difficult to identify exactly which assets are critical to a specific business function. If a DR plan fails to account for a hidden dependency (e.g., an external authentication service), the recovery will fail.
Mitigation Strategies:
- Mission Thread Analysis (MTA): I would apply the framework proposed by Corbari et al. (2024) to map the “Mission Relevant Cyber Terrain.” This process involves tracing a specific operational thread (e.g., “Process Customer Payment”) end-to-end to identify every critical node and link.
- Shared Responsibility Awareness: Organizations must clearly define where the vendor’s security responsibility ends and theirs begins, particularly regarding data encryption and access control.
