2022-05-06	feat(faas): Add helper tools for FaaS simulations	Fabian Mastenbroek
	This change adds a new module, opendc-faas-workload that contains helper code for constructing simulations of FaaS-based workloads using OpenDC. In addition, we add an integration test that demonstrates the capabilities of the helper tool and the FaaS platform of OpenDC.
2022-05-06	refactor(workflow/service): Remove OpenTelemetry from "FaaS" modules	Fabian Mastenbroek
	This change removes the OpenTelemetry integration from the OpenDC FaaS modules. Previously, we chose to integrate OpenTelemetry to provide a unified way to report metrics to the users. See the previous commit removing it from the "Compute" modules for the reasoning behind this change.
2022-05-06	refactor(faas/service): Directly expose scheduler/function stats to user	Fabian Mastenbroek
	This change updates the `FaaSService` interface to directly expose statistics about the scheduler and individual functions to the user, such that they do not necessarily have to interact with OpenTelemetry to obtain these values.
2022-02-18	refactor(utils): Rename utils module to common module	Fabian Mastenbroek
	This change adds a new module, opendc-common, that contains functionality that is shared across OpenDC's modules. We move the existing utils module into this new module.
2022-02-18	feat(utils): Add Pacer to pace scheduling cycles	Fabian Mastenbroek
	This change adds a new Pacer class that can pace the incoming scheduling requests into scheduling cycles by allowing the user to specify a scheduling quantum.
2022-02-15	refactor: Update OpenTelemetry to version 1.11	Fabian Mastenbroek
	This change updates the OpenDC codebase to use OpenTelemetry v1.11, which stabilizes the metrics API. This stabilization brings quite a few breaking changes, so significant changes are necessary inside the OpenDC codebase.
2021-10-25	refactor(simulator): Support running workloads without coroutines	Fabian Mastenbroek
	This change updates the SimMachine interface to drop the coroutine requirement for running a workload on a machines. Users can now asynchronously start a workload and receive notifications via the workload callbacks. Users still have the possibility to suspend execution during workload execution by using the new `runWorkload` method, which is implemented on top of the new `startWorkload` primitive.
2021-09-17	refactor(telemetry): Create separate MeterProvider per service/host	Fabian Mastenbroek
	This change refactors the telemetry implementation by creating a separate MeterProvider per service or host. This means we have to keep track of multiple metric producers, but that we can attach resource information to each of the MeterProviders like we would in a real world scenario.
2021-08-25	build: Upgrade to OpenTelemetry 1.5	Fabian Mastenbroek
	This change upgrades the OpenTelemetry dependency to version 1.5, which contains various breaking changes in the metrics API.
2021-06-17	faas: Rename opendc-serverless to opendc-faas	Fabian Mastenbroek
	This change renames the opendc-serverless module to opendc-faas to better distinguish between the two terms (Serverless and FaaS) and be clearer about the intent of the module. The opendc-faas module holds the code for the FaaS platform on top of OpenDC. Although this is one approach of doing serverless, serverless can also entail other services that will not be covered by this module.
