A computer-implemented method, in accordance with one aspect of the present invention, includes receiving, by a sender multi-protocol gateway (MPG) implemented in software, data from a sender application for transmission to a receiver endpoint. The data is validated against a predefined schema definition by the sender MPG. In response to successfully validating the data, a service request is made, by the sender MPG, using preconfigured information. An endpoint of the service request is a receiver MPG configured to forward the validated data to a receiver application in communication with the receiver endpoint. The receiver MPG is configured to not reply in any way to the sender MPG and sender application in response to receiving the service request.

Software-based cross domain solutions

A computer implemented method comprises receiving a request to provision a container as a software container on a current node of the cluster. The method further comprises accessing a performance information data store (PIDS) to obtain a record associated with the container that includes benchmarked performance metrics including container-required resources associated with a benchmark-specified node of the container. The method further comprises accessing the PIDS to obtain a record associated with the current node of the cluster that includes current-node performance metrics associated with the current node. The method further comprises comparing the benchmarked performance metrics with the current node performance metrics to determine that a difference exists, and conditioned upon the difference existing adjusting, with a resource adjustment calculator, the container-required resources based on the determination of how much of a difference exists. The method then provisions the container on the current node with adjusted container-required resources.

Optimizing CPU requests and limits for a pod based on benchmarked hardware

Mechanisms are provided for optimizing remuneration for computing services. Computing services are registered which stores registration data comprising remuneration associations between computing services and consumers. A hierarchical computer model is generated based on the registration data, where the model represents dependencies between consumers and providers of computing services. For a service request from a consumer, each transaction with each computing service in a service invocation chain associated with the service request is identified and a cost of each transaction is calculated. The calculated cost of the service invocation chain is optimized based on applying an optimization algorithm to a cost function applied to a selected portion of the hierarchical computer model corresponding to the service invocation chain.

Computer service invocation chain monitoring and remuneration optimization

Service assurance is provided. A low priority pod corresponding to a low priority service in an orchestration platform that is to be evicted due to a predicted peak load period of a high priority service is identified based on analysis of historical and resource information. The low priority service corresponding to the low priority pod that is to be evicted due to the predicted peak load period of the high priority service is marked as an assured service for a guaranteed run in response to receiving an input from a user who was notified regarding eviction of the low priority pod. The low priority pod corresponding to the low priority service that is to be evicted due to the predicted peak load period of the high priority service is provisioned on a second host node prior to the eviction of the low priority pod from a first host node.

Selecting low priority pods for guaranteed runs

An approach for providing a framework to maintain continuous access to web content bookmarked in a browser, the framework comprising web content storage, change detection and change notification. Embodiments of the present invention create and store a snapshot of bookmarked web content with a version number in a repository and the snapshot is replaced by a new snapshot whenever bookmarked web content is updated, while access to previously versioned snapshots is maintained. Change detection comprises automatically subscribing to content update notification services provided by a web content provider and receiving updates, comparing the content of a most recent snapshot with the web content available from the content provider and detecting a change to the bookmarked URL. Keywords from a snapshot can be used to relocate web content at a new URL and a web browser user is notified whenever a change to bookmarked web content is detected.

Maintaining continuous access to web content

A migration set list generator specifies a physical topology of a deployed software solution, wherein the software solution comprises software components and data associated with the software components, integrated into a single entity. The migration set list generator specifies at least one solution change to the deployed software solution to meet at least one business requirement and specifies at least one migration strategy for migrating the deployed software solution. The migration set list generator generates migration tasks for making the at least one solution change to the deployed software solution specified in the physical topology based on the at least one migration strategy and generates a recommended physical topology yielded for the software solution if the physical topology is updated according to the migration tasks.

A computer system retrieves from data repositories change information indicating changes to entries. Each data repository is associated with a corresponding interface and at least two data repositories are associated with different interfaces, and at least one data repository lacks tracking of changes to entries stored therein. The change information retrieved from the data repository is stored within a storage unit. The stored information includes identification of each repository entry change without storage of the changed entry. Requests are processed to provide change information for entries within the data repositories, wherein processing the change information request for one of the entries includes retrieving from the storage unit the identification of the repository entry change for the one of the entries. Embodiments of the present invention further include a method and computer program product for tracking changes within data repositories in substantially the same manner described above.

Tracking changes to data within various data repositories

Session state affinity is maintained in a workload balancing system that includes a hypertext transfer protocol (HTTP) routing server and a plurality of application servers. The application servers maintain backup session state information for a first session to a first server of the plurality of application servers at fewer than all of the plurality of application servers, detect the unavailability of the first application server at an application server of the plurality of application servers other than the first application and determine a second server that continues the first session. An identification of the second server and the first session is sent from an application server of the plurality of application servers to a HTTP routing server responsive to detecting the unavailability of the first server. The identification of the second server and the first session is received at the HTTP routing server and communications associated with the first session are routed from the HTTP routing server to the second server responsive to receiving the identification of the second server so that backup session state information maintained at the second server is used to continue the first session from the first server at the second server.
