A computer-implemented method for distributing a copy of event data recorder (EDR) data of a vehicle includes sending index information uniquely identifying respective member vehicles of a dynamic vehicle network that include candidate vehicles located within a predetermined geo distance of a host vehicle, sending a fragment of a private key associated with EDR data of the host vehicle to the respective member vehicles of the dynamic vehicle network, distributing segments of replicated EDR data from the host vehicle among the respective member vehicles, and responsive to an expiration of a predetermined lifecycle duration associated with the dynamic vehicle network and an absence of an incident of the host vehicle: disbanding the dynamic vehicle network, and initiating a next dynamic vehicle network including a set of next candidate vehicles.

Methods for managing a connection pool for cloud-based applications accessing databases are provided. Aspects include establishing a plurality of connections to one or more databases, receiving connection requests from a plurality of cloud-based applications to access the one or more databases, and allocating the connection requests to among the plurality of connections, where the allocation is determined based at least in part on one or more connection pool parameters. Aspects also include monitoring a usage of the plurality of connections by the plurality of applications and updating the one or more connection pool parameters based on an analysis of the usage of the plurality of connections by the plurality of applications.

A computer-implemented method for a service mesh to simulate and address a situation in which there are several transactions among services with an asynchronous relationship between the services is provided. The computer-implemented method includes identifying that the situation occurs with a response provided to a user upon a user invocation of one of the services, analyzing the situation to determine that the asynchronous relationship between the services caused an error in at least one of the several transactions, recording data of a next user invocation of the one of the services, modifying the data of the next user invocation of the one of the services to correct the error and to thereby generate modified data, simulating an execution of the next user invocation of the service using the modified data and confirming that the modified data corrects the error based on results of the simulating.
