Cloud Proposal Issues
Txture endeavors to identify the most suitable target architecture for a given application, aligning with the specified target architecture preferences. The resulting cloud proposals are determined by the modeled deployment stack, available data, and the selected strategy. However, Txture's capabilities in finding proper replacements for specific parts of the deployment stack may be limited. There can be various reasons why Txture doesn't suggest a specific cloud replacement. Such reasons include unavailable products at the desired target location, unavailability of marketplace solutions in Txture and others. The cloud proposal issues can help you identify these reasons and, if possible, resolve them so that you can find the target architecture most suitable for your needs.
If there are any potential issues in generating specific cloud proposals, these will be displayed under the 'Available Proposals' tab in the Target Architecture phase for an application. Click on 'Show Issues' to learn more.
The issues are split into two groups: general issues and specific issues, respectively.
General issues
These issues typically pertain to the modeled deployment stack. For example, if a technical component within the application cannot be containerized, cloud products like Kubernetes cannot be used. Another common general issue occurs when an asset lacks an assigned technology property. For instance, if an application uses a database without a designated technology, Txture will not suggest specific replacements such as Amazon RDS for SQL Server.
Each issue comes with an explanation designed to assist you in taking the necessary steps to resolve it. In general, it's advisable to examine the deployment stack of the application, validate the modeled stack, and address data gaps, such as missing technologies.
Specific issues
Specific issues are usually related to the target architecture preferences, such as the selected cloud providers.
They can be accessed the same way as before, namely in the Available Proposals tab.
You have the option to filter the specific issues by providers, location, assets and products. This depends on the Target Architecture Preferences set and the involved issues.
A common example of these issues is that no cloud replacement could be found for a specific asset. Note, that this can be caused by the location that is set in the target architecture preferences. Cloud providers often do not offer all their products at all locations and thus cloud replacements can sometimes not be found at a specific location. To solve this specific issue, relax the constraints set for the allowed location in the target architecture preferences. Other issues might need a varying approach.
