Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions according to review and approval workflows. The transaction exchange platform may receive transactions from origination sources, which may be added to the SDP as transaction objects. Microservices on the transaction exchange platform may interact with the transaction objects based on configured workflows associated with the transactions. Processing on the transaction exchange platform may facilitate clearing and settlement of transactions. Some aspects may provide for pausing the processing of transactions during a workflow. Other aspects may provide for a messaging microservice that permits communications between the transaction exchange platform and external third-parties.

Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions according to review and approval workflows. The transaction exchange platform may receive transactions from origination sources, which may be added to the SDP as transaction objects. As the transactions are processed, the transactions may require access to a resource (e.g., a key value in a database). A microservice processing the transaction may request, from a locking microservice, a lock for the resource. The locking microservice may query a local cache to determine whether a lock exists for the resource. If the local cache determines that no lock exists for resource, the locking mechanism may employ a consensus protocol to obtain a lock for the resource from a plurality of clusters. If consensus is reached, a lock for the resource may be granted to the requesting microservice.

Aspects described herein may relate to a transaction exchange platform using a streaming data platform (SDP) and microservices to process transactions in accordance with corresponding workflows. The transaction exchange platform may generate configuration transaction objects to reconfigure microservices with salt values and time periods of salt value validity. Further, the microservices may retrieve transaction objects from a streaming data platform and generate hash signatures as part of determining the validity of the transaction objects. Furthermore, in some aspects the microservices may retrieve salt values for transaction objects that cannot be verified due to the absence of a hash signature. The salt values may be retrieved from a blockchain associated with the streaming data platform and may be used to update the microservice to include the salt value.

Systems as described herein may include generating an aggregated service status report for a real-time service delivery platform. A plurality of services running in a service domain may be determined. A request for a status of system behavior corresponding to a particular service may be received. Service connection details of the particular service may be discovered and metric data of real-time data movement may be tracked. Real-time snapshot aggregation of the particular service may be provided. In a variety of embodiments, a real-time system behavior report for the service across availability zones may be presented.
