Shared Memory vs Message Passing
Developers should learn shared memory when building applications that require low-latency communication between processes, such as real-time systems, high-performance computing (HPC), or multi-process architectures like database systems meets developers should learn message passing when building systems that require high concurrency, fault tolerance, or distributed coordination, such as microservices, real-time applications, or cloud-based platforms. Here's our take.
Shared Memory
Developers should learn shared memory when building applications that require low-latency communication between processes, such as real-time systems, high-performance computing (HPC), or multi-process architectures like database systems
Shared Memory
Nice PickDevelopers should learn shared memory when building applications that require low-latency communication between processes, such as real-time systems, high-performance computing (HPC), or multi-process architectures like database systems
Pros
- +It is particularly useful in scenarios where large datasets need to be shared quickly, such as in scientific simulations, video processing, or financial trading platforms, to avoid the performance penalties of data duplication
- +Related to: inter-process-communication, parallel-computing
Cons
- -Specific tradeoffs depend on your use case
Message Passing
Developers should learn message passing when building systems that require high concurrency, fault tolerance, or distributed coordination, such as microservices, real-time applications, or cloud-based platforms
Pros
- +It is essential for avoiding shared-state issues in multi-threaded environments and for enabling communication across network boundaries in scalable applications
- +Related to: concurrent-programming, distributed-systems
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Shared Memory if: You want it is particularly useful in scenarios where large datasets need to be shared quickly, such as in scientific simulations, video processing, or financial trading platforms, to avoid the performance penalties of data duplication and can live with specific tradeoffs depend on your use case.
Use Message Passing if: You prioritize it is essential for avoiding shared-state issues in multi-threaded environments and for enabling communication across network boundaries in scalable applications over what Shared Memory offers.
