## Context
|
|
|
|
The system is made up of five distinct bounded contexts, namely the Task Domain, the Roster Domain, the Executor Pool Domain, the Executor Domain, and the Auction Domain. The way that these bounded contexts function together to fulfil the system requirements can be based on many different architectures. (Feedback needed. Should we name specific 'next-best' alternative architectures to compare, or just leave it as is since technically all architectures were considered)
|
|
|
|
## Decision
|
|
|
|
The system will follow the Microservice architecture.
|
|
|
|
Scalability and fault tolerance are two of the systems top 3 -ilities. Moreover, elasticity and evolvability are two of the systems other main -ilities. These are all non-functional requirements that the Microservice architecture excels at.
|
|
|
|
We do not expect to have a single monolithic database, so this is not a concern.
|
|
|
|
## Consequences
|
|
|
|
There is a considerable amount of communication between bounded contexts. This could cause responsiveness and performance issues due to added latency. This could therefore mean we would need to use asynchronous REST calls or publish-subscribe communication to mitigate these issues as much of the communication does not have to be synchronous.
