Credentials management and usage in application modernization

A non-transitory computer-readable medium storing instructions which, when executed by a hardware-based processor, performs operations comprising:

• receiving, at credential management system and via an application programming interface (API), a notification identifying an application modernization operation to be performed on an application deployed by one of a plurality of resources arranged in a plurality of hierarchical levels;
• identifying, by the credential management system, a resource on which the application modernization operation is to be performed, the resource having a resource type and residing at a hierarchical level of the plurality of hierarchical levels;
• searching, by the credential management system and from among a plurality of credentials, for a credential that grants access to the resource to perform the application modernization operation, each of the plurality of credentials mapping to one of plurality of hierarchical levels;
• determining, by the credential management system and in response to the searching, that no credential is specifically associated to the resource;
• performing by the credential management system and in response to determining that no credential is specifically associated to the resource, additional searching for a credential that grants access to the resource to enable performing the application modernization operation but that is not specifically associated to the resource;
• identifying, by the credential management system and in response to the additional searching, a credential included in the plurality of credentials, that grants access either to the resource or to resources of the resource type;
• and
• providing, by the credential management system and in response to receiving the notification, the identified credential via the API.

A system comprising:

• one or more processors including a hardware-based processor;
• and
• a memory storage including a non-transitory computer-readable medium storing instructions which, when executed by the one or more processors including the hardware-based processor, performs operations comprising:
• receiving, at credential management system and via an application programming interface (API), a notification identifying an application modernization operation to be performed on an application deployed by one of a plurality of resources arranged in a plurality of hierarchical levels;
• identifying, by the credential management system, a resource on which the application modernization operation is to be performed, the resource having a resource type and residing at a hierarchical level of the plurality of hierarchical levels;
• searching, by the credential management system and from among a plurality of credentials, for a credential that grants access to the resource to perform the application modernization operation, each of the plurality of credentials mapping to one of plurality of hierarchical levels;
• determining, by the credential management system and in response to the searching, that no credential is specifically associated to the resource;
• performing by the credential management system and in response to determining that no credential is specifically associated to the resource, additional searching for a credential that grants access to the resource to enable performing the application modernization operation but that is not specifically associated to the resource;
• identifying, by the credential management system and in response to the additional searching, a credential included in the plurality of credentials, that grants access either to the resource or to resources of the resource type;
• and
• providing, by the credential management system and in response to receiving the notification, the identified credential via the API.
