Currently, microservice architecture is very popular, which also led to many teams to adopt microservices in practice without thinking ( not considering the size of the team, nor the development of the business, nor the support of the underlying technology ). However, there are also many problems after blindly using microservices. Contents Pitfalls of Implementing Microservices ...

Microservices include the concept of “service”, and SOA (Service Oriented Architecture) also has the concept of “service”, we will naturally ask: what is the relationship between microservices and SOA? Why do we still need microservices when we have SOA? If you are going to use microservices architecture, it is important to understand the above questions. If you don’t understand these question...
