In lieu of shared memory, shared structures can be stored locally and retrieved via interprocess communication. What architectural flaws does it possess?

It would be preferable if the structures weren't kept in shared memory but rather were kept in each process' local memory and accessible via interprocess communication. What are a few of this design's flaws?

What is dynamic memory, and how is it distinct from static memory?

What difficulties does an operating system need to address when implementing a concurrent multithreading architecture?

In software architecture, what is the difference between microservices and monolithic architecture, and what factors influence the choice between them?

Explain the concept of multithreading and list three common threading models used in concurrent programming.

Is concurrency feasible in operating system threading without parallelism?

Multiprogramming's primary benefit is...

In what ways may an operating system's thread-rich design provide difficulties?

Instead of keeping the structures in shared memory, it would be preferable to have them kept in the local memory of each process and accessible through interprocess communication. I was wondering what the flaws of such a layout may be.
