Aspects of the present disclosure relate to audio/video (A/V) stream functionality verification. A stream segment of a video feed prior to transmission over a network as captured by a transmitting device within a web-based conference can be stored. A stream segment of the video feed after transmission over the network as received by a receiving device within the web-based conference can be stored. The stream segment of the video feed prior to transmission over the network can be compared with the stream segment of the video feed after transmission over the network to determine a video feed quality.

Audio/video (A/V) functionality verification

Various embodiments migrate a legacy application to a multi-tenant computing environment. In one embodiment, at least one virtualized computing container is instantiated on a host system in a multi-tenant computing environment. An instance of the legacy application is executed within the virtualized computing container. The legacy application having been initially configured to run on premise and serve one tenant at a time. The virtualized computing container securely isolates the executing instance of the legacy application from other executing instances of the legacy application. At least one request received from a first client is sent to the instance of the legacy application executing within the virtualized computing container. The virtualized computing container is quiesced based on at least one quiescing criterion having been satisfied by the instance of the legacy application.

Migrating legacy applications to a multi-tenant computing environment

Methods, systems, and products are disclosed in which generating evidence of web services transactions are provided generally by receiving in an ultimate recipient web service from an initial sender a request, the request containing a proof of message origin ('PMO'). The PMO contains an element addressed to the ultimate recipient web service and the element bears a first signature, the first signature having a value. Embodiments also include authenticating the identity of the initial sender; creating a proof of message receipt ('PMR') including signing the value of the first signature; sending the PMR to the initial sender, receiving, by the initial sender, the PMR; and saving, by the initial sender, the PMR.

Generating evidence of web services transactions

Embodiments relate to determining a process outcome based on a computed probability and altering the path of a process instance based on an expediting rule. An aspect includes executing, by a processing device, a process instance in a process diagram, which includes a plurality of process steps. A condition associated with a first process step is identified. An outcome for the first process step is then determined based on a computed probability. Accordingly, the first process step is bypassed and the process instance is branched to a second process step based on an expediting rule. The expediting rule includes the condition and a branching action according to a selected outcome.

Expedited process execution using probabilities

A method, system and computer program product for security model for workflows aggregating third party secure services. In one embodiment, a workflow model described in a workflow language is provided and configured to declare security requirements of a composite application integrating protected data from two or more external network resources. The method also incorporates providing an authentication service executing on at least one secure server computer. The authentication service is configured to conduct user authentication and authorization to access the protected data at the external network resources on behalf of the composite application executing on at least one host server computer according to the workflow language.

Security model for workflows aggregating third party secure services

A computer implemented method, apparatus, and computer usable program product for processing application code. In one embodiment, a call is received to invoke a set of methods of annotated application code. The annotated application code includes a set of annotations specifying a selection of the set of methods. A selected method from the set of methods is invoked in response to determining that the call is valid according to the set of annotations. Thereafter, a subsequent set of valid methods for execution is identified based upon an annotation associated with the selected method.

Controlling navigation of application logic using annotated application code

A method for modeling a process includes receiving a plurality of graphs representing processes wherein for each graph. A sequence of process steps of the processes are represented as nodes and edges connecting pairs of nodes represent transitions between process steps. A numeric value representative of graph appearance for each of the plurality of received graphs is calculated. Each of the plurality of received graphs is stored within a tree-like data structure according to its corresponding numeric value. Each of the above steps is performed using a computer system.

Dynamic storage and retrieval of process graphs representative of business processes and extraction of formal process models therefrom

A method for modeling a process includes collecting data pertaining to executed process steps from one or more activity log files. The collected data is parsed to determine a set of process steps that have been performed. An incidence value representing how many times each performed process step follows each of the other performed process steps is determined. A graph representing a model of the executed process by representing each process step that has been performed as a node of the graph and each transition between process steps within each process thread as an edge on the graph is generated. The edges connecting the pairs of nodes are assigned numbers that depend upon the incidence value corresponding to how many times the process step represented by a first node of the pair is followed by the process step represented by a second node of the pair.

Dynamic adaptive process discovery and compliance

A method for predictive analytics in a semi-structured process including receiving traces of the semi-structured process, at least one of the traces including a document content value, determining a process model from the traces, the process model comprising tasks at nodes of the semi-structured process and embodies all possible execution sequences in the process, determining a probabilistic graph including a probability at each of the tasks of the semi-structured process advancing from one task to another task, and combining the process model and probabilistic graph to determine a probabilistic process model including probabilities and strengths of transitions between tasks.
