Cost-Effective Cloud Solutions for Migrating Perpetual License Database Applications

D.

The most cost-effective option when moving to the cloud with a perpetual license for a database application is "BYOL" (Bring Your Own License).

Explanation: When a company moves to the cloud, they have different pricing models to choose from, such as fixed pricing, subscription-based pricing, and pay-per-use pricing. However, when a company already owns a perpetual license for an application, the most cost-effective option is to use that existing license in the cloud environment. This is where BYOL comes in.

BYOL allows a company to use their existing licenses in the cloud environment without having to purchase new licenses or pay for additional software. This can save the company a significant amount of money, as they do not have to pay for additional licensing fees.

Fixed pricing is not the best option as it can be expensive for the company, especially if they only need to use the application for a short period. Subscription-based pricing may also not be cost-effective, as the company may end up paying for more licenses than they need. EULA (End User License Agreement) is not a pricing model, but rather a legal agreement that outlines the terms and conditions of using the software.

In summary, the most cost-effective option when moving to the cloud with a perpetual license for a database application is to use BYOL, as it allows the company to use their existing licenses without having to pay for additional licensing fees.
