Future Work

This page contains a list of potential future projects and extensions for MiSim. These are rather high-level targets for future releases.

Features

Status	Name	Description
Done ✔️ (3.1+, external)	Kubernetes Orchestration	see here
Done ✔️ (3.1+)	Branching of Requests	Request dependencies can now branch between multiple targets
In Progress ⏳ (target 3.3+)	Asynchronous Output Writing	Instead of saving all generated output data in memory, it is now written continuously and asynchronously. This hugely improves performance and allows for data analysis even when the simulation should crash.
In Progress ⏳	Testing Framework Improvements	Currently, the testing framework mainly supports unit testing and a bit of E2E testing (e.g. Reproducibility). The new framework aims to add the option to do integration test by supplying MiSimModel and Experiment Mocks that can be used to acces the inner workings of the simulation during testing.
In Progress ⏳	MTL/LTL Input Support	Complex architecture or experiment behaviour can be described by MTL or LTL formulars.
Idea 💡	Simulate Asynchronous Communication	Currently MiSim only simulates synchronous communication and that also in a non-optimal way.
Idea 💡	CPU performance degradation	The more load/heat a CPU experiences, the slower it gets. Goes along with boosting behavior.
Idea 💡	Modelling I/O loads	Improve the resource modelling to simulate I/O tasks.
Idea 💡	Request Paths	Define concrete Paths of specific requests.
Idea 💡	Fix Dependency Graph	see Issue 40
Idea 💡	Selectable Output Metrics	Instead of outputting all Metrics, just output the ones needed.
Idea 💡	Cold Start Behavior

Resilience Mechanisms

Status	Name	Description
Done ✔️	Autoscaling
Done ✔️	Circuit Breaker
Done ✔️	Retry
Done ✔️	Load Balancer
Idea 💡	Rate Limiter
Idea 💡	Throttling	May makes sense in combination with modelling CPU performance degradation
Idea 💡	Simulating Caching
Idea 💡	Bulkheads
Idea 💡	Fallback
