Abstract: Determining correct base container images to support custom container images is provided. A comparison between layers of a base container image corresponding to a current version of an operand and layers of a custom container image built by a user is performed using an operator. It is determined whether the user utilized a correct base container image to build the custom container image based on the comparison between the layers of the base container image corresponding to the current version of the operand and the layers of the custom container image built by the user. A runtime is generated in a cluster of host nodes to provide a service based on the custom container image in response to determining that the user utilized the correct base container image to build the custom container image.

Abstract: Dynamically calculating and re-calculating priority values for a set of microservices that are deployed and run in a containerized environment. Before new priority values are assigned to the microservices, an initial default priority value is assigned to a microservice of interest. When the microservice of interest is deployed and run in the containerized environment, the generated telemetry data is used, in part, as a basis to determine a frequency in which any given microservice is being utilized, and more particularly, the microservice of interest. Based upon the determined frequency, a role for the microservice of interest can be inferred. As a result, this inferred role for the microservice of interest is used to dynamically assign a current priority value for the microservice of interest.

Traffic is then routed to configured shards.

Abstract: A method, computer system, and computer program product for migrating a service (e.g. microservice) from using a first application programming interface version to using a second (e.g. newer or updated) application programming interface version. The method may include determining a difference between specifications of the first and second versions of the application programming interface. Historical usage of the first version of the application programming interface by the service may then be analyzed with respect to the difference so as to determine if the service meets the specification of the second version of the application programming interface. Responsive to determining the service meets the specification of the second version of the application programming interface difference, the service may be migrated from using the first version of the application programming interface to using the second version of the application programming interface.

Abstract: Batch compression management of messages. A message being sent to a batch for transmission is intercepted. The message is assigned to a batch pool, in which multiple batch pools are provided as sub-sets of the batch. The assigning of the message to the batch pool is based on a similarity of properties of the message with other messages and determined by looking up the properties in a batch pool mapping database. The message is added to the batch pool or a new batch pool is created for the message. A batch pool of messages is compressed using a dictionary of the properties common to at least some of the messages in the batch pool. The compressed batch pools are transmitted over an input/output channel.

Abstract: A computer-automated method, computer system and computer program for managing resources in applications. The resources are managed in groups, each group having a unique group name which is dynamically resolvable to an address specific to a particular application. The resources may be application program interfaces object instances or data sources, for example. When a resource placement request is received to place a resource in a particular application with an associated address, the resource is assigned to a group and given a unique resource identifier which combines with the group name to form a unique endpoint for the resource. Subsequently, in response to detection of a resource performance bottleneck, or in response to an external request, a resource is moved to another application by reassigning its group name to the second address, thereby moving all resources in that group to the other application.

Abstract: Disclosed embodiments provide automated techniques for evaluation of a user interface of a computer application. A computer function associated with a graphical element such as an icon or button is analyzed. The resultant text that appears as a result of invoking the button is analyzed and keywords are identified to determine a function type for the function. A graphical element category is determined for the button/icon that is invoked to produce the function. The graphical element category can be determined by analyzing underlying markup code for the button. Keywords pertaining to the button may be extracted from the markup code. The keywords from the button are compared with the keywords of the resulting function and a score is generated based on the amount of common keywords. The score is used as a criterion for a recommendation about the appropriateness of the button for use with the application function.
