  • Patent number: 12355843
    Abstract: A method, system, and computer program product for protecting API KEYs for accessing services in a cloud environment are disclosed. A first request for generating a virtual key for a user in an organization to access a service in a cloud environment is received. The first request includes information of the organization, an identity of the user, and information of the service. A first authentication request is sent to an identity provider of the organization based on the information of the organization and the identity of the user. In response to the first authentication being successful, an API key for the organization to access the service is determined. The virtual key for the user to access the service is generated based on the API key, the information of the organization, and the identity of the user. The virtual key is returned as a response of the first request.

  • Patent number: 12253995
    Abstract: Increasing index search efficiency and availability in a database is provided. An index space matrix corresponding to a plurality of mini-indices of the database is built using ordered boundary values that correspond to key value ranges of each respective mini-index to increase index search efficiency by removing redundant mini-index accesses. Mini-indices of the plurality of mini-indices are consolidated asynchronously without suspending access to the mini-indices using a particular consolidation policy of a plurality of consolidation policies that corresponds to an amount of key value overlap identified between the mini-indices. Data operations corresponding to transactions are performed using the index space matrix during consolidation of the mini-indices without suspending access to the mini-indices.

  • Publication number: 20240160482
    Abstract: A method, computer system, and a computer program product is provided for dynamic allocation of resources. A database access pattern is determined by analyzing and monitoring traffic pattern between a pool of resources and a plurality of clients. The relationship between each of the resources is also determined. Access is enabled to a plurality of resources based on the database access and resource relationships, so that the plurality of resources can be accessed but not allocated until processing a request. A consumption model is generated that predicts resource need during a processing request based on the resource relationships, traffic pattern and resources availability. Upon receipt of a subsequent request for processing, consumption model is used to predict resource needs and to dynamically allocate, re-allocate and release the plurality of resources in a cascading manner until completion of subsequent processing request.

  • Publication number: 20240111550
    Abstract: A computer-implemented process is disclosed. An application is loaded into a local address space. A request by the application to load a target shared library is intercepted by an interceptor. Using the interceptor and based upon the request being intercepted, a shared library correlation table is searched for a loading count and a loading policy associated with the target shared library. Based upon the loading count and the loading policy, a selection is made between loading the target shared library as a shared library container, and loading the target shared library into the local address space. The target shared library is loaded based upon the selecting. The loading count represents a number of times the target shared library was loaded, and the loading policy indicates how the target shared library is to be loaded.

  • Publication number: 20240095072
    Abstract: A method includes, in response to receiving an incoming service request and establishing a call chain of pods of a service mesh network, setting a retry locker parameter to a locked state for each pod in the call chain. A locked retry locker parameter prevents the pod from initiating retries of a service request. The method includes, in response to determining that a pod in the call chain is unavailable, setting the retry locker parameter to an unlocked state for a previous pod just prior to the pod that is unavailable. The unlocked state allows a retry to the pod that is unavailable. In response to the previous pod reaching a retry limit, the method includes setting the retry locker parameter to unlocked for each pod in the call chain and sending a service termination message to a service requester.

  • Patent number: 11853810
    Abstract: Edge device task management is provided. It is determined whether a subtask cancel and migrate plan exists when a request to run a higher priority subtask of a second plurality of subtasks corresponding to a second task is received while a first task comprised of a first plurality of subtasks is running on a first cluster of edge devices. In response to determining that the subtask cancel and migrate plan does exist, a lower priority subtask of the first plurality of subtasks is canceled from a designated edge device of the first cluster of edge devices based on the subtask cancel and migrate plan.
