Figure $1$ Realization of a software system in the form of two service$-$oriented architecture variants $($UI AUser Interface$)$

Figure $1$ shows two different implementations $($variant A and variant B$)$ of a software system. Both variants use the Service$-$Oriented architectural

stvle. Compare and iudge both variants, the properties of Fenler tolerance and scalability as better$/$worse or the same.

Justify your assessment in detail, taking into account the following requirements

If you classify one variant as better or worse than the other variant, then please explain explicitly why one variant is better and also why the other is better in this regard. worse behaved

Your assessment must relate to the architectural level, i$.$e$.$ how well the properties are supported by the architecture

Fault tolerance Stability of the system when errors occur such as: Individual crashes Modules$/$Components

Scalabilitv: Abilitv to adapt a svstem to a higher workload $($as opposed to elasticity no dynamic adjustment is required$)$

Note: When considering fault tolerance, consider the case where services require the data of another service in the database for certain tasks, but not their actual business logic,
