A container deployment system for managing the installation of virtual containers in a cloud computing system is disclosed. The container deployment system retrieves runtime information of a plurality of virtual machines and containers installed in a cloud computing system. The retrieved runtime information includes information of a plurality of read-only layers in the plurality of virtual machines and containers. The container deployment system retrieves a policy requesting one or more of the plurality of read-only layers for installation of a new container in the cloud computing system. The container deployment system determines a virtual environment in the cloud computing system including the one or more of the plurality of read-only layers requested in the policy based on the retrieved runtime information, and installs the new container in the virtual environment.

Virtual container deployment

A solution is proposed for deploying a virtual appliance onto a data processing system. A corresponding, method comprises instantiating the virtual appliance with a basic configuration onto the data processing system, determining a value of each one of a set of environmental features at a virtual data processing environment associated with the virtual appliance, and downloading a set of local software programs corresponding to the values of at least part of the environmental features onto the virtual appliance.

Dynamic configuration of virtual appliances

A solution is proposed for deploying a virtual appliance onto a data processing system. A corresponding method comprises instantiating the virtual appliance with a basic configuration onto the data processing system, determining a value of each one of to set of environmental features of a virtual data processing environment associated with the virtual appliance, and downloading a set of local software programs corresponding to the values of at least part of the environmental features onto the virtual appliance.

A mechanism is provided for distributing a service implemented by a plurality of infra-connected source virtual machines on a source computing environment. Characteristic information of the service comprising an indication of the intra-connected source virtual machines and of each intra-connection between the intra-connected source virtual machines is discovered. The source virtual machines are copied into corresponding target virtual machines on a target computing environment. Reconfiguration information of at least one selected target virtual machine of the target virtual machines is saved that has a source identity of the corresponding source virtual machine in the source computing environment being reconfigured into a target identity of the at least one selected target virtual machine in the target computing environment. Each communication, addressed to each source identity by each target virtual machine intra-connected to a corresponding selected target virtual machine, is redirected to the corresponding target.

Distribution of a service implemented by intra-connected virtual machines

A processor-implemented method, system, and/or computer program product deploys software images onto a computing system. A first computing machine is instantiated from a software image onto a computing system. The first computing machine has a first old access identifier, and is initially connected to a second computing machine in the computing system via a second old access identifier for the second computing machine. The second computing machine is reconfigured to have a new access identifier by: retrieving the new access identifier for said second computing machine, and associating the new access identifier with the second old access identifier; and redirecting each outbound communication, from the first old access identifier to the second old access identifier, to the new access identifier of the second computing machine.

Deployment of software images with run-time reconnection

A method for identifying a problem in a software application is presented. The method may include enabling a user to define at least one usage scenario for a software application. The software application may be executed on a reference computer system according to the usage scenario and data reflecting a status of the reference computer system and the software application during execution may be acquired. The software application may be further executed in a subject computer system according to the usage scenario. Data reflecting a status of the subject computer system and the software application during execution may likewise be acquired. Finally, the data from the reference computer system may be compared with the data from the subject computer system to identify at least one difference therebetween.
