+# 2. Seperate service for Executors and Executor Pool
+
+Date: 2021-11-21
+
+## Status
+
+Accepted
+
+## Context
+
+The executor pool has a complete list of all executors and knows if they are available or not, executors can execute tasks that match their type. The executors can therefore be part of the executor pool service, or each executor is a standalone service, as well as the executor pool.
+
+## Decision
+
+We will use a separate microservice for each executor and one service for the executor pool.
+Having the executor pool and the executors as separate services would increase fault tolerance. If the executor pool goes down, the executors would stay online and execute their tasks without being affected by the executor pool’s outage. Likewise, if an executor goes down it does not impact other executors or the executor pool.
+Different executors can have different execution times and a different load. This means the executors scale differently. Thus, we need a separate service for each executor.
+Executors of different kinds will also scale differently than the executor pool and new executors of new types might be added at some point, further increasing the need for separate services to guarantee scalability and evolvability.
+New executors will be added/removed during runtime. Therefore, we need a high extensibility.
+
+## Consequences
+
+Executors will be added/removed quite frequently, making the deployment of the system easier and less risk-prone if each executor is a separate service, also separated from the executor pool, which just keeps track of the executors and their status. However, having these separate services, the complexity might increase, and the testability of the system will decrease.

+## Status
+
+Accepted
+
+## Context
+
+Tasks are created in the task list, and the status of each task (created, assigned, executing, executed) is tracked in the task list as well. The task list mainly communicates with the roster so that tasks can get assigned and the roster will give the task list feedback about the tasks’ status.
+
+## Decision
+
+The task list will be its own service.
+The task list needs to scale based on the number of active users and the intensity of their activity at any time while the scaling of other parts of the system can be constrained by other factors.
+
+## Consequences
+
+Although having the task list as its own service might slightly increase the complexity of the system and decrease the testability, it also makes the system easier to deploy and protective of its data. However, to ensure that this data is always available and does not get lost, the task list needs to be able to recover all its data (the entire history of all tasks) in case it goes down.

+
+## Status
+
+Accepted
+
+## Context
+
+The auction house is the service that can connect to other groups’ auction houses. If there is a task whose task type does not match that of our executors, the auction house can start an auction where other groups can bid on doing the task for us. Moreover, it can also bid on other groups’ auctions.
+
+## Decision
+
+The auction house will be its own service.
+The auction house is the only part of our system that has external communication; therefore, it makes sense to have it as its own service, also to guarantee better deployability.
+The auction house does not scale directly based on the number of tasks, but only the proportion which needs external executors. Moreover, there could be limits on the number of auctions that could be started. Therefore, the auction house scales differently to other services.
+Moreover, having the auction house as its own service also improves the fault tolerance of our system.
+
+## Consequences
+
+Since the auction house will be a standalone service, we have to make sure that if it goes down, it can recover its data in some way (which auctions it has launched, which auctions it has placed bids on or even won, etc.). Even though the testability and latency of our system might worsen by having a separate service for the auction house, we can implement different kinds of communication for internal and external communication in a much easier way.

+
+Date: 2021-11-21
+
+## Status
+
+Proposed
+
+Supercedes [5. Event driven communication](0005-event-driven-communication.md)
+
+## Context
+
+Our Tapas App is currently implemented based on a microservice architecture, where the services communicate synchronously via request-response. Each service encapsulates a different bounded context with different functional and non-functional requirements. Internal communication could also be done using asynchronous or event-driven communication.
+
+## Decision
+
+Pros:
+Scalability: Different services within the Tapas app are not always able to scale at the same rate. For example, we could have thousands of users adding printing tasks at the same time, but maybe we only have one printer. In this scenario we might want to scale the task-list service up to handle the creation load, but scaling up the printing executor operates on a different time-scale (i.e. adding a printer takes time). Moreover, we could have a lot of new tasks coming in, most of which can be executed internally. In this case we want to be able to scale up the task list but might not need to scale up the auction house. Event-driven communication would decrease the coupling of services. Consequently, the scalability of individual services would be enhanced as they no longer depend on the scalability of other services. This improves the apps overall scalability. Since scalability is one of the systems top 3 -ility, this seems quite important.
+Fault tolerance: Another of the systems top 3 -ilities is fault tolerance. We could have highly unstable IoT executors that fail often. This should not disrupt the system’s overall operation. The decoupling facilitated by event-driven, asynchronous, communication ensures that when individual services go down, the impact of other services is limited and once they go back up then can recover the systems state from persisted messages.
+Cons:
+Error handling, workflow control, and event timing:
+The aforementioned topics outline the drawbacks of event- driven architecture. These drawbacks can be mitigated by using an orchestrator (like we currently do with the roster) to orchestrate assignment of tasks, auctioning off tasks and error handling when executors fail. More research needed.
+
+## Consequences
+
+Consequences to be determined but would relate to the three concepts mentioned as cons.

+# 10. executor base library
+
+Date: 2021-11-21
+
+## Status
+
+Accepted
+
+## Context
+
+Executors all use the same logic to communicate with other services. This means that their code base is near identical except for the code that implements their specific task execution. The code that implements the executor's shared logic can either be implemented by a shared library, or replicated across all executors.
+
+## Decision
+
+Since all executors use the same logic to communicate with other services, any change to this logic would have to be made for every executor. We will therefore use a shared library for executors, called executor-base. The library includes all the shared logic which every executor needs. 
+Having this shared logic in a separate library makes it easy to change the common logic at one place. The code sharing happens at compile time, which reduces the chance of runtime errors, compared to other code sharing approaches. If other people need to create executors, they can just reference the executor-base library and implement the actual execution part. Therefore they don’t need to worry about the the connection implementations to the Tapas system. 
+
+## Consequences
+
+It becomes easier to change the way that the executors communicate with the rest of the system. Moreover, changes are less risky as they only need to be implemented once. It also becomes easier for other teams within the organisation to create executors as they can use the executor-base to implement the shared logic. However, using a shared library will increase the complexity of the executors. Also there needs to be a clear way to use proper versioning. Lastly, by using this library we might be making assumptions for future executors that might not hold. For example, if we want to create more lightweight executors for IoT devices we might need to create a separate base package (if the current one becomes too fat), so that the executors can stay lightweight and don’t implement unused code.

+# 11. seperation of common and executor-base library
+
+Date: 2021-11-21
+
+## Status
+
+Accepted
+
+## Context
+
+We have two code sharing libraries, the executor-base and the common library. The executor-base implements shared logic that all executors need, but other services don't. The common library has much more wide reaching implementations, such as the implementation of the SelfValidating class. These could form a single common library, or two seperate common libraries. 
+
+## Decision
+
+There will be a separate library for common and executor-base. The libraries share different type of code, and have different reasons to change. It would not make sense to have the shared code from executors in every other service which needs access to other shared code. Services that use the code in the common library should not need to be dependent in any way on the executor-base.
+
+## Consequences
+
+Changes impact fewer services. However, this decision will increase the number of service dependencies and therefore increase complexity in managing those dependencies.
