Python, on the other hand, is a dynamically-typed language. This feature does not suit well when the team grows or the lines of code increase significantly, as developers find more runtime errors. The system, therefore, becomes complex and hard to maintain at a high scale.
Another side of the scalability is human, which is about the situation when the development team grows in size or when the number of code changes done by developers in a system. If we compare Java to Python, then Java’s static typing comes in handy while scaling the system in terms of adding more features (lines of code). As Java is a more verbose language with strict rules of coding and also consists of a type safety system which produces fewer errors at runtime, Java allows the system development to grow at high scale smoothly (in terms of lines of code).
Microservice is the software development technique which structures an application as a collection of loosely coupled service. Each service is self-contained and should implement a single business capability. Microservice architecture is designed to overcome the challenges, failure, and breakdown of the larger applications. Microservices provides opportunities to add resiliency to the system so that components can handle spikes and errors gracefully. With this, every stakeholder can focus solely on one particular element of an overall application, with their own programming style without concerns about other components. The communication in micro-services can be carried out effortlessly because they are stateless and in the well-defined interface (request and response are independent).
