Implementing loose coupling for isolating faults

While redundancy plays a vital role in achieving fault tolerance, it is not a panacea on its own. Even with redundant components in place, tightly coupled systems can propagate failures across the entire architecture, leading to widespread outages and compromising the overall resilience of the system. This is where the principle of loose coupling becomes crucial.

Loose coupling is a design approach that emphasizes decoupling components and services within a system, reducing their interdependencies, and minimizing the impact of failures. By embracing loose coupling, you can create more modular and independent systems, where failures in one component do not cascade through the entire architecture. This isolation of faults not only enhances fault tolerance but also simplifies the maintenance, scalability, and future extensibility of your applications. In a tightly coupled system, components are heavily dependent on each other, often...
