Described are techniques for exposing an endpoint for a software function used by microservices. The techniques include obtaining software classes of a plurality of microservices and analyzing the software classes to identify a software function that is eligible for conversion to an application programming interface (API) format. The techniques further include determining a server microservice, which hosts a software class that includes the software function, and one or more client microservices that use the software function. The techniques further include generating deployable source code implementing an API that exposes the software function hosted by the server microservice to the one or more client microservices. The API uses a software wrapper to encapsulate software function semantics used by a monolith application refactored into the plurality of microservices.

Automated generation of application programming interfaces for microservices

Recommending database access patterns for transactions in microservices is provided. A recommendation of a particular database access pattern to improve access by transactions to data in fields of tables in a database corresponding to a microservice is generated based on analysis of field access graphs for the tables accessed by the transactions. The recommendation of the particular database access pattern is output. The particular database access pattern is implemented to improve access by the transactions to the data in the fields of the tables in the database corresponding to the microservice to improve performance of the microservice based on user input and read view implementation guidance.

Automatically recommending database access patterns for transactions in microservices

Techniques for recommending microservices to perform the different functions of a legacy architecture are disclosed. In one example, a computer implemented method comprises receiving a plurality of recommendations comprising a plurality of program components as candidates for assignment to a plurality of microservices, and determining roles of respective ones of the plurality of program components. A user interface is provided which is configured to allow a user to modify one or more of the plurality of recommendations based at least in part on the roles. Modifications to the one or more of the plurality of recommendations are analyzed, and one or more metrics are computed based at least in part on the analysis.

Microservices recommendation framework

Methods, systems, and computer program products for translating clusters of a monolith application to microservices are provided herein. A computer-implemented method includes obtaining a plurality of candidate microservices for refactoring a monolith application, each candidate microservice including one or more of a plurality of software classes of the monolith application; analyzing the monolith application to identify one or more software functions in the plurality of software classes to expose as one or more application programming interfaces; automatically isolating non-overlapping software functions of the monolith application between the plurality of candidate microservices; converting source code corresponding to the identified one or more software functions into a standardized application programming interface format based at least in part on the isolating; and using the converted source code to generate a plurality of deployable microservices corresponding to the plurality of candidate microservices.

Translating clusters of a monolith application to microservices

Generating a user interface template is provided. A user context corresponding to an action request by a user to perform a task on a computer is determined. A set of user interface templates corresponding to the action request by the user and the user context is retrieved. Components of different user interface templates within the set of user interface templates are compared. Relevant components of the different user interface templates are combined based on the action request by the user and the user context. The user interface template corresponding to the action request by the user and the user context is generated based on the combined relevant components of the different user interface templates.

One embodiment provides a method, including: monitoring a first chat channel within a distributed collaboration environment; identifying an outage affecting a service associated with the first chat channel; providing, to at least a second chat channel associated with at least a second service, a notification of the outage affecting the service, wherein the at least a second service is identified as having a dependency on the service; determining, at the at least a second chat channel, the outage is causing an incident with the at least a second service, wherein the determining comprises monitoring the at least a second chat channel for messages related to the incident; and interjecting, within the at least a second chat channel, a message regarding the outage affecting the service.

Real-time fault localization detection and notification

Methods, systems, and computer program products for determining a recommended set of actions from operational data are provided herein. A computer-implemented method includes associating multiple action templates with a set of operational data corresponding to a query; selecting a first action template from the multiple action templates; identifying one or more attributes associated with the first action template; forming a first step of a resolution action in response to the query by populating the first action template with at least one of the attributes; repeating, based on the first step of the resolution action and the set of operational data, said selecting, said identifying, and said forming for at least a second action template to form a second step of the resolution action; and outputting the resolution action, wherein the resolution action comprises a fixed sequence of at least the first step and the second step.

A method and system. A library method stub is created in a predefined programming language by use of a library method signature associated with an original library call, at least one idiom sentence, and a call invoking the original library call. Creating the library method stub includes composing source code of the library method stub by matching the at least one idiom sentence with idiom-stub mappings predefined for each basic idiom of at least one basic idiom. The original library call appears in sequential code. The library method signature specifies formal arguments of the original library call. The at least one idiom sentence summarizes memory operations performed by the original library call on the formal arguments. The created library method stub is stored in a database.

Analyzing task associations may compute artifact associations for a plurality of artifacts based on historical task submission logs. From the computed artifact associations, shared artifacts that have artifact association with targeted artifacts that are associated with planned tasks, may be determined. Task association between the planned tasks may be identified based on the shared artifacts. Task associations may be analyzed to determine one or more of task assignment and task schedule for the planned tasks.
