APPLICATION PATTERN DISCOVERY

API associations among a plurality of service application programming interfaces may be identified by analyzing service API call logs, which contain data associated with invocation of the plurality of application programming interfaces by a plurality of applications, wherein sets of APIs that are determined to be called together are identified. For a set of service APIs, a plurality of applications that invoke the APIs in the set is identified. A sequence of API calls by an application in the plurality of applications is identified, wherein multiples sequences of APIs are identified, one sequence of API calls identified respectively for one application in the plurality of applications. An application pattern is determined based on the multiple sequences of service APIs.
