This change removes the opendc-core module. This module was an artifact
of the old codebase and remained mostly unused. This change removes all
usages of the module and if necessary introduces replacement classes.
|
|
|
|
This change adds the ability to define labels and meta-data for
resources. This can be used in the future to identify servers and pass
data between client and server.
|
|
This change adds more methods for controlling the lifecycle of Server instances.
|
|
This change removes the usage of bare-metal provisioning from the OpenDC
Compute module. This significantly simplifies the experiment setup.
|
|
This change moves the bare-metal provisioning packages outside the
compute module since these modules represent different layers in the
ecosystem and should not be mixed.
|
|
This change introduces the ComputeService interface (previously
VirtProvisioningService) and provides a central implementation in
opendc-compute-service.
Previously, the implementation of this interface was bound to the
simulator package, which meant that independent business logic could not
be re-used without importing the simulator code.
|
|
This change extracts the API for the OpenDC Compute service into a separate
module to establish a clearer boundary between the interface meant for
consumers and interfaces meant for the the serve implementation.
|
|
This change converts the Server data class which can be used as a
stateful object to control an instance running in the cloud.
|
|
This change refactors the OpenDC Compute module so that the
VirtProvisioningService is now responsible for managing the lifecycle of
Server objects as opposed to the VirtDriver and BareMetalDriver
previously.
|
|
This change removes the use of ServiceRegistry in the OpenDC compute
module. It was not actually being used by any of the code and we are
moving to another interface in the future.
|
|
This change separates the cloud compute layer in OpenDC (e.g., Server)
from the bare-metal layer (e.g., Node), such that Node and
BareMetalDriver are unaware of the existence of Server and co.
|
|
This change removes the SimWorkloadImage implementation and changes
Image to a data class without workload. Simulation workloads should now
be pased via image metadata as the image storage should be unaware of
any simulation details.

This commit implements the energy models that are present in CloudSim:
1. Constant
2. Linear
3. Cubic
4. Square root
5. Interpolation based on data.

|
This change allows users to select the hypervisor scheduler to use when
deploying hypervisors onto bare-metal machines.
|
|
This change adds a new hypervisor implementation that supports virtual
machine that have exclusive access to resources (e.g., CPU).
|
|
This change converts the low-level workload model to be pull-based. This
reduces the overhead that we experienced with our previous co-routine
based approach.
|
|
This change updates the workflow service to delegate the resource
scheduling logic to the virtualized resource provisioner.

This change splits the opendc-compute module into two modules:
1. opendc-compute-core
The interfaces and APIs that represent a IaaS platform.
2. opendc-compute-simulator
The implementation of these interfaces using simulation components
from opendc-simulator-compute.
