More on Advantages
Explore the major advantages of microservices architecture including enhanced robustness through resilience, the ability to scale components independently, freedom to choose diverse technologies, and improved security by isolating services. Understand how isolation supports modularity and long-term maintainability in microservice systems.
We'll cover the following...
Robustness #
Microservice systems are more robust.
When a memory leak exists in a microservice, only this microservice is affected and crashes. The other microservices keep running. Of course, they have to compensate for the failure of the crashed microservice; this is called resilience.
To achieve resilience, microservices can cache values and use them in case of a problem. Alternatively, there might be a fallback to a simplified algorithm.
Without resilience, the availability of a microservice system might be a problem. It is likely that a microservice will fail for any reason.
- For example, due to the distribution into several processes, many more servers are involved in the system. Each of these servers can potentially fail.
- Communication between microservices occurs via the network, which can also fail. Therefore, microservices need to implement resilience to achieve robustness.
Independent scaling #
Most of the time, scaling the whole system is not ...
