Here's a helpful table summarizing the cost components:

- Pay-as-you-go model for most services. |
- High upfront costs for hardware, software, and facilities. |
OPEX |
- Variable costs based on usage. |
- Fixed costs for IT staff, power, cooling, and bandwidth. |
Additional Considerations |
- Highly scalable and flexible. |
- May require additional investment for scalability, flexibility, and security.

Ultimately, the best option for your organization will depend on your specific needs and requirements. A thorough TCO analysis that considers all of the relevant costs and factors can help you make an informed decision.
