Canonical Resources (Erl)
How can unnecessary infrastructure resource disparity be avoided?
Service implementations can unnecessarily introduce disparate infrastructure resources, thereby bloating the enterprise and resulting in increased governance burden.
The supporting infrastructure and architecture can be equipped with common resources and extensions that can be repeatedly utilized by different services.
Enterprise design standards are defined to formalize the required use of standardized architectural resources.
If this pattern leads to too much dependency on shared infrastructure resources, it can decrease the autonomy and mobility of services.
Services use the same standardized infrastructure resource for the same purpose. Note, however, that they do not share the same implementation of the resource.
