Correct answer: B) Host all your subsidiaries' services together with your existing services on the public cloud.
Hosting all your subsidiaries' services, along with your existing services, on the public cloud offers several advantages. Here's why:

Reduced Overhead: Public cloud providers offer managed services that can significantly reduce the overhead associated with infrastructure management. You can leverage these services for various tasks, such as server provisioning, scaling, and maintenance, allowing your teams to focus on application development and business growth.

Cost Efficiency: Public cloud services often follow a pay-as-you-go model, allowing you to scale resources based on demand. This flexibility can help in optimizing costs, especially during periods of variable workloads.

Global Reach: Hosting on the public cloud enables you to have a global presence without the need for significant infrastructure investments in each country. This is particularly beneficial when dealing with subsidiaries in different countries.

Security and Compliance: Leading cloud providers invest heavily in security measures and compliance certifications. Leveraging these services can enhance security without the need for extensive in-house security expertise.

Options A, C, and D may not be as efficient or cost-effective:

Option A: Hosting everything on-premises might lead to increased infrastructure management overhead and may not scale well for global operations.

Option C: Building a homogenous infrastructure at each subsidiary may increase training costs and may not provide the same level of efficiency as leveraging managed services from a public cloud provider.

Option D: Hiring more engineers may not be the most cost-effective solution, especially if the goal is to reduce overhead. Additionally, finding and retaining skilled engineers in different countries may pose challenges.
